Thermo Scientific Prima PRO:The Next Generation Begins
Backed by more than 30 years of process mass spectrometry success,the next-generation Thermo Scientific Prima PRO has been engineered
to meet a number of challenging iron and steel applications, including:• Blast furnace optimization• Primary steel production• Secondary steel production• Direct reduced iron processing• Electric arc furnace control• Coke oven gas optimization.
The Prima PRO decreases coke consumption and increases yields via
precise analysis of a wide range of process gases. Highly reliable andeasy-to-own, this modern process mass spectrometer (MS) delivers
faster, more complete, lab-quality online gas composition analysis,
enabling real-time optimization of many hot metal processes. Gas
concentration and derived value measurements include higher and lower
calorific value (CV), density, specific gravity (SG), Wobbe Index (WI),
Stoichiometric air requirement (SAR) and combustion air requirement
index (CARI) as well as complete and precise compositional analysis.
Rapid payback, superior measurement quality and minimal maintenancerequirements make the Prima PRO the analytical technology of choicefor gas analysis within the iron and steel industry.

Principles of Operation
The cornerstone of the Prima PRO, and the preferred technology forhighly stable, rapid gas analysis, is the scanning magnetic sector MS.
Using this technology, gas is continuously drawn from the sample
conditioning system via a multi-stream inlet into the ion source where
the gas molecules are ionized and fragmented. The ions are accelerated
at high energy into the electromagnetic mass filter before selected ionsare counted at the detector. The fragmented molecules produce a very
repeatable ‘fingerprint’ spectrum, allowing gases with similar molecularweights to be measured with high accuracy and without interference.
The onboard controller presents gas concentration data and derived
values, such as CV and WI, directly to the process control system using
a variety of industry standard protocols. A rugged, fault-tolerant design
ensures availability, typically exceeding 99.7%, while maintenancerequirements are significantly minimized.

New Models Deliver Strong ROI• Fast (1 to 20 seconds per point) online gas analysis for accurate
tracking of process dynamics• Comprehensive compositional gas analysis results in more data
supplied to advanced process control (APC) models• Stable with a 30- to 90-day calibration interval (automated)• Reliable, fault-tolerant design for availability of >99.7%• Small footprint with no large shelter required; standard A/C sufficient• Minimal maintenance requirements reduce operating costs

Imagine a Gas Analyzer that Can Pay You Back in Days.

Blast Furnace Optimization
The blast furnace is charged with iron oxide bearing sinter pellets (FeO),
flux and coke which are loaded into the furnace through a rotating
distributor or chute. To achieve correct distribution of these materials,
the feed rate and the order that the materials are fed into the top must
be controlled. Indirect reduction of the iron ore by carbon monoxidetakes place inside the top of the blast furnace stack between+300°C to +1400°C (+570°F to +2550°F):

g 2Fe3O4 + CO2
Fe3O4 + CO g 3FeO + CO2
FeO + CO g Fe + CO2

3Fe2O3 + CO

At higher temperatures, direct reduction takes place:
FeO + Cg Fe + CO

For a blast furnace producing 5,000 tons of pig iron,a reduction in coke consumption of just 10 kg per tonof iron produced provides a payback of approximately$13,000 per day. Upgrading to a Prima PRO can result
in complete installation payback within 30 days.

Precision is the standard deviation observed over 24 hours and assumes
an analysis time of 15 seconds. For shorter analysis time (n seconds),
down to three seconds minimum, the precision specification data aremodified according to:
Precision for n seconds analysis time equals (12/(n-3)) 0.5 x (precision
for 15 s analysis time). For five and 10 second analysis times,
the precision will be worse by factors of 2.4 and 1.3 respectively.

The optimum coke rate is achieved when direct reduction is maximized.
Table 1: Typical mass spectrometer performance specification

Top Gas Analysis Using the Prima PRO
The Prima PRO provides accurate measurement of CO, CO2, N2 and H2.
If there is too much CO in the top gas, chemical heat will leave
the furnace and coke consumption will be too high. If the CO2 is too
high, heat will be carried from the furnace by the exothermic reaction
2CO > C + CO2.
The N2 measurement is an important parameter for the online kinetic
process models that are used for deriving mass balance, heat balance,
fuel capacity and hot metal production.
H2 is measured for safety reasons. If the reading is too high, it indicateswater is leaking into the furnace, creating a dangerous situation thatcan result in explosions. Gas composition measurement is particularly
important during the end-of-campaign blowdown that takes place prior
to rebuilds and relines because explosive gas mixtures can be generated.
Burden probes are often used to collect periodic temperatureand gas composition profiles. These data points are used to monitor
burden distribution.

Primary Steel Production
Basic Oxygen Steel Making
Molten iron from the blast furnace is decarburized at the steel plant
when pure oxygen is blown at supersonic speeds through a water-cooled
retractable lance. This process reduces the carbon content by oxidization.
Furnaces used for this process are often referred to as converters,
basic oxygen furnaces (BOF), or the basic oxygen process (BOP) or
Linz Donawitz (LD) converters. A typical vessel holds 280 tons of steel
with the carbon content reduced on average from 4% to 0.3 to 0.6%,
depending on the target chemistry.
During this process, the ladle is charged with 20% scrap. Molten
iron is added to achieve the required charge balance. Before the lanceis lowered, the typical chemistry is 4% carbon, 0.5% silicon, 0.1%
phosphorous and 0.02% sulfur. Once the lance is lowered, the carbon isburned to form CO and CO2. The temperature rises to +1700°C (+3000°F),
melting the scrap and lowering the carbon content. At this point, fluxes
are fed into the vessel to form slag which absorbs impurities. In addition,
the CO helps to purge N2 from the steel. Variations to the converter
include bottom-blowing Tuyeres which enable efficient stirring via
a mixture of oxygen and inert gases, including N2 and/or Ar.

Furnace Effluent Gas Analysis
Using the Prima PRO
Analysis of CO and CO2 using the Prima PRO enables detection of theprocess endpoint to minimize oxygen use, ensure a faster process
and avoid slopping which damages the furnace. Where a process uses
both N2 and Ar to reduce chromium oxidation, the Prima PRO’s gas
composition data helps to minimize consumption of expensive Ar byaccurately controlling the optimum switchover point. However, reducing
the number of reblows is the primary goal. Fast, accurate gas analysis
reduces the need for intermediate hot metal at-line sampling whichadds up to six minutes to the heat time or up to 6% of tap-to-tap time.
Furthermore, a reblow adds 5 to 10 ppm of N2 to the steel when air
is added to the furnace during the sampling rotation.

Cryogenic Air Separations
Air separation plants generate pure O2, pure Ar and pure N2 which
are required for primary steel conversion. A molecular sieve in the
pre-purification unit (PPU) removes water, CO2 and oxides of N2.
The dry air entering the cold box consists of 78.11% N2, 20.95% O2 and
0.94% Ar. Distillation columns cryogenically separate the three gases,
and the residual O2 is removed from the Ar in a second distillation stage.
With Ar costs approximately 80 times those for nitrogen, N2 is thepreferred inert stirring gas. Unfortunately, low carbon sheet steels
intended for special applications (i.e., automobile body panels) requirevery low N2 contents (20 to 50 ppm), making it is necessary to use
Ar once the N2 limit has been reached.

Recirculation Degassing (R-H Process)Degassing removes the H2, N2, O2 and C that react with the O2 whenthe vacuum is applied. This process reduces the number of inclusions,improving toughness, fatigue strength and machinability of the final
product. Better control of the steel’s cleanliness is also a prime
degassing benefit. Alumina, inherent in all steel making processes,
is a major source of poor steel cleanliness. The use of slags with anaffinity for alumina enables production of very clean steel products.
In the R-H version of this process, an evacuated vessel is lowered into
the ladle and hot metal is drawn up through one of a pair of snorkel
tubes into the degassing vacuum chamber. Ar is injected into one tube inorder to initiate vigorous recirculation as well as boiling of the hot metal.

Vacuum-Oxygen Decarburization (VOD)
Using the Prima PRO
The VOD process is used to convert unrefined steel into stainless steel
or other high quality, ultra-low carbon steel. Once the ladle is charged,
the converter top, consisting of a vacuum hood with an oxygen lance anda hopper for desulfurizing slag treatments and alloying elements, is closed.
The pressure in the vessel is lowered from atmosphere (1000 mbar) to
1 mbar or less using large multi-stage steam ejectors or three-stage dry
pumping systems. The lance blows O2 over the melt while Ar is bubbled
up from the bottom in order to purge the carbon oxidation products andremove impurities. Incorporating the Prima PRO’s sample tap into thevacuum system enables direct monitoring of decarburization and degassing
for optimum process control. The Prima PRO can also be used to calculate
total gas flow from the vessel via an accurately metered helium injection,an arrangement that provides comprehensive data to the kinetic control
models. In the production of ultra-low carbon steel (less than or equal to
30 ppm), a mean error of 1 ppm in the carbon content is achievable when
the Prima PRO’s unique magnetic sector MS provides data to the APC system.

Each 1% increase in throughput is worth approximately $20,000 per day

Direct Reduced Iron (DRI)
The direct reduction process converts iron ore into metallic iron by
reducing gases in a shaft furnace. Reducing gases, including coke ovengas (COG), can be generated by an external gas steam reformer orby gasification of fossil fuels. During the DRI process, O2 is removed
from the iron ore by chemical reactions based on H2 and CO, resulting
in the production of DRI pellets. During electric furnace steelmaking,
DRI pellets or briquettes are used to dilute the contaminants present
in the scrap metal. When the DRI is delivered hot to the furnace,energy consumption is reduced by as much as 20%.

Technology: Midrex
With Midrex technology, the charge is fed continuously from the topof the furnace, passing uniformly through the furnace’s preheat,
reduction and cooling zones. The H2 and CO reducing gas is heated
to +760°C to +925°C (+1400°F to +1700°F) and is fed from the bottomof the furnace, below the reducing section. The gas flows upward
through the descending iron ore fines. The partially spent reducing
gas (approximately 70% H2 and CO) exits the top of the furnace.
It is recompressed, enriched with natural gas, and transported to the gas
reformer where the mixture composition is returned to 95% H2 and CO.
In the cooling zone, the cooling gases flow countercurrent to the DRI.
At the top of the cooling zone, the cooling gases exit, are sent torecycling and finally return to the bottom of the cooling zone.
The reduced iron fines are turned into pellets or briquettes, producing
a usable DRI product.

Technology: Tenova HYL
In the Tenova HYL process, reformed natural gas (NG) is used to reduce
lump ore and fixed pellets in four reduction reactors. Prior to the gas
reformer, NG is mixed with steam and is passed over nickel-based
catalysts. Excess steam is added to prevent carbon formation and toextend catalyst life. Once past the gas reformer, the NG is quenchedto remove the water, resulting in a hydrogen-rich reducing gas.
Reduction of the charge occurs in two sections and takes place above+980°C (+1800°F) to raise the reduction efficiency. The cold NG entersa third section and is used for product cooling and carburization.
Product cooling occurs at or around +550°C (+1000°F) and resultsin time carbon being deposited to form a cementite (Fe2C) shell that
retards reoxidation. The DRI is transported hot to the electric arc furnace
to reduce the amount of energy required to melt the furnace charge.

Benefits of Prima PRO Gas Analysis• Optimizes production of reducing gases• Optimizes direct reduction process• Optimizes fuel gas mixing• Reduces energy consumption• Provides rapid installation payback• Ensures low total cost of ownership

Electric Arc Furnace (EAF)The EAF, together with the basic oxygen furnace, is one of two modern
steelmaking techniques. Unlike the basic oxygen process, the EAF does
not use hot molten metal. It is charged with solid material, normally steel
scrap and DRI. The steel scrap is first tipped into the EAF from an
overhead crane. Next, a retractable cover, containing electrodes thatare lowered into the furnace, is swung into position over the furnace.
An electric current, typically supplied by a 100 mw transformer, is passed
through the electrodes to form an arc that generates enough heat
to melt the scrap. O2 can also be lanced into the scrap, or wall-mounted
oxygen fuel burners can be used to provide additional chemical heat.
The retractable cover includes a hood that diverts gases through a
post-combustion section and a dust removal system. As with othersteel processes, burnt lime and dolomite are added to form a slag thatblankets the molten steel and absorbs impurities. The slag also covers
the arc, preventing radiant heat damage to the furnace cover andsidewalls. Carbon in the form of coke or coal is lanced into the slag,
partially combusting to form CO which causes the slag to foam.
Greater thermal efficiency and better arc stability result. Once themeltdown is complete, the oxygen lance is used to burn off impurities(Si, P, S, Al, Mn and Ca) and any byproduct oxides are absorbed by
the slag. Finally, the C content is lowered by the O2 from the lance.
Once the process is complete, the furnace is tilted and the molten
steel is tapped into a preheated ladle.

Furnace Control Using the Prima PRO
The primary furnace control goals are to minimize energy usage, provide
consistent steel specifications, achieve environmental compliance andensure safe operation. Furnace off-gas composition, measured in realtime, is used to continuously optimize chemical energy and to control
post-combustion for bag house safety and environmental compliance.
The gas measurement is achieved via an extractive system that employs
rugged water-cooled probes and a sophisticated sample conditioning
system. The output is a reliable off-gas sample for the Prima PRO which
in turn provides precise gas composition measurement for dynamic,
model predictive process control.

Benefits of Prima PRO Gas Analysis• Minimizes power consumption• Minimizes oxygen consumption• Minimizes tap-to-tap times• Improves process safety

Coke Oven Gas
In the coke oven plant, coal is converted into coke by pyrolysis.
To begin the process, the coal is baked in an airless furnace or ovenat +2000°C (+3600°F) or higher to extract volatile constituents, including
water, coal gas and coal tar. A large quantity of gas with high CV isgenerated, with the oven operating largely by reusing or burning thegases emitted by the coal. There are two main aspects to analyzing thehigh CV gas. The first is to precisely measure its energy characteristics,
enabling it to be used efficiently as fuel for the oven batteries as well
as fuel for other stoves and furnaces. Properties of the gas, includingCV, density, SG, WI and SAR, are simultaneously calculated by thePrima PRO. These variables enable tight combustion control to maximize
energy use and to extend burner life. The second aspect to the gas
analysis is the essential cleaning of the gas to prevent problems
associated with gas handling and to limit harmful emissions. Rapid andcomplete analysis of the gas at various points, including at the secondary
cooler, ammonia absorber, final cooler and benzol scrubber, allows for
closed loop control of the cleaning process. One multi-stream Prima PRO
optimizes both the fuel burning and gas cleaning processes for a
cost-effective installation with low cost of ownership.

Fuel Gas Analysis
In general, furnaces are operated at constant temperature with a gas
fired furnace ideally burning a gas of constant composition that isdelivered at a constant rate and is using a constant air intake at thecorrect rate for complete combustion. However, gas supply in iron andsteel works is of varying composition and the rate of gas supply needs tobe varied to maintain a constant temperature. The rate of air supply mustalso be varied to minimize energy wastage if too little or too much air isused. In addition, excess air can cause metal surface defects due tooxidation. In a typical integrated iron and steel works, the gases listed inTable 4 are used either singly or in mixtures as fuel gases. The tableillustrates typical CV and the corresponding SAR needed for optimum
combustion.
Analysis of fuel gas composition enables the precise heating
properties to be predicted for feed-forward control. CV is calculated fromthe analyzed composition according to the sum of the pure component
CVs that are weighted on a mole fraction basis. However, in practice, thefuel gas flows through a restriction, such as an orifice or valve. The
actual flow is inversely proportional to the square root of the density of
the gas, making WI more practical than CV. The WI is defined as:
Wobbe Index =calorific value
specific gravity

The ideal analyzer is capable of fast, online determination of both WI
and CARI, enabling feed-forward control. The Prima PRO is the preferredtechnique for these measurements because the magnetic sector MS
provides comprehensive, accurate, fast and very stable fuel gas analysis.
Using the Prima PRO, analysis of all components present in fuel gas,including H2, CH4, CO, N2, O2, C2H6, CO2, C3H8, C4H10 and C6H6, iscompleted in less than 30 seconds with a precision of typically better
than 0.1% relative or 0.01 mol% absolute.
The multi-stream Prima PRO measures blast furnace gas (BFG), cokeoven gas (COG), LD converter gas (LDG) and NG. It provides accurate gas
compositions as well as reports precise values for lower and/or higher
heating value, lower and/or higher WI, density and CARI. These data arecommunicated directly through one of many available data highways forfeed-forward control of gas mixing and air supply.

Alternative Technology Comparison
In principle, there are simpler, lower cost instruments capable ofmeasuring some fuel gas properties. However, the measurements
made by the Prima PRO are more complete, accurate and faster.
Calorimeters, which measure the heat effect of burning fuel gas, canbe used to measure CV or WI but not both simultaneously. A calorimetercan be combined with a density meter to provide data for calculating
the other property. The precision of a Prima PRO is typically a factorof 10 times better (0.1% relative compared with 1% relative for acalorimeter). Response time is also typically a factor of 10 times better(15 seconds for the Prima PRO compared with 2.5 minutes for acalorimeter). Calorimeters cannot be used to measure CV of fuel gasesof widely varying composition or to calculate the SAR which is essential
for efficient combustion. SAR is sometimes determined by measuringexcess oxygen in the furnace using a discrete oxygen analyzer. However,this approach involves additional complexity and can be prone to errors
if there are air leaks in the furnace. Prior to using a MS to measure fuelgas and due to the unsuitability of the calorimeter to measure multiple
streams and sample types, the only solution included multiple
calorimeters and density meters plus a discrete oxygen analyzer.
The cost, complexity and maintenance requirements of a single
Prima PRO make it an extremely favorable solution in comparison
with the older multi-analyzer system. Flexibility is another advantageof the Prima PRO. It is very easy to modify the analytical method tomeasure different components, negating any problems if the sample
gases are changed over time. For example, the analytical method
for NG can be easily changed to include CO2, C5H12 and C6H14,
if significant concentrations of these components are present due
to changes in the supplied NG.

Benefits of Prima PRO Gas Analysis• Reduces natural gas consumption• Extends burner lifetime• Reduces scab formation caused by excess O2• Enables environmental complianceEnhance Productivity and Increase ROI.
