As one of the oldest compressor designs, reciprocating
compressors (recips) enjoy unique capabilities and are quite
flexible with features such as broad capacity control ranges
and the ability to compress gas regardless of mole weight or
k value. Add multiple stages and they can compress a gas toextremely high pressure ratios. Consequently, they are an ideal fit
for selected applications—such as hydrogen compression in thede-sulfurization process of many refineries—and as part of the
low-density polyethylene production process in chemical plants.

However, reciprocating compressors suffer from one very serious
drawback: high maintenance costs. In fact, compared to similarly
sized centrifugals, recips can consume as much as five times theamount in maintenance costs.

That’s why a continuous monitoring system is so important.
Specifically designed to meet the unique machinery protection
and condition monitoring needs of recips, our solutions, which
include safety integrity level (SIL) certified products can help close
the gap, bringing your recip maintenance costs closer to thelevels associated with centrifugals while simultaneously improving
reliability, availability, and safety. And, with patented technology,
comprehensive services, and over 55 years of experience
monitoring reciprocating compressors, no one is better equipped
to help you than Bently Nevada, a Baker Hughes business.

Recip monitoring—in detail
1. Crosshead vibration

Crosshead-mounted accelerometers can detect machinery problems due toimpact-type events such as excessive crosshead clearance, liquid ingestion into thecylinder, excessive clearance in the crosshead pin bushing, and loose or cracked
nuts, bolts, liners, or pistons.

3500 Monitor: 3500/70M Four-Channel Impulse/Velocity Monitor
Transducer: 330425 Accelerometer
Crosshead shoe temperatureContinuous monitoring of crosshead shoe (slipper)
temperature provides useful information on developing
slipper problems such as overload, fatigue, andinsufficient lubrication.

3500 Monitor: 3500/60 or 3500/61 Six-Channel or
3500/65 16-Channel Temperature Monitor
Transducer: RTD or Thermocouple
2. Frame vibration

Increases in frame vibration can indicate problems such as imbalance due tounusual pressure differential or inertial unbalance, looseness in the foundation
attachment (such as deteriorating grout or shims), and high moments caused byexcessive rod load.

3500 Monitor: 3500/70M Four-Channel Impulse/Velocity Monitor
Transducer: 190501 Velomitor CT Piezo-Velocity Transducer
3. Main bearing temperatureThis measurement indicates problems related to fluid-film bearings, including
overload, bearing fatigue, or insufficient lubrication.

3500/65 16-Channel Temperature Monitor
Transducer: RTD or Thermocouple
4. Cylinder chamber pressure profiles

The single most effective way of determining the overall health of a reciprocating
compressor is by examining the cylinder pressure profile. Online access to theinternal pressure for each cylinder chamber enables continuous monitoring of
cylinder pressures, compression ratios, peak rod loads, and rod reversal. This
provides valuable information on the condition of suction valves, discharge valves,piston rings, packing glands, and crosshead pins. And, interfacing the 3500 systemwith System 1 software provides valuable diagnostic plots such as Pressure versus
Volume (P-V), Log P versus Log V, Pressure versus Crank Angle (Theta-θ) (P-T), androd load curves. Performance monitoring is a standard feature of System 1 software
for chamber pressure measurements and delivers important information such as
indicated horsepower, flow balance, and power losses.

Continuous rod load

Combined (inertia and gas) rod load calculated at the crosshead pin provides
information about the lubrication condition of the crosshead pin. Insufficient reversal
or excessive rod load can be identified and corrected before costly running gear
damage occurs.

3500 Monitor: 3500/77M Four-Channel Cylinder Pressure Monitor
Transducer: 165855 Cylinder Pressure Transducer
5. Piston rod/plunger position

Horizontal and vertical proximity probes observing
the piston rod provide information on rod bow, rod
flex (vibration), and rider band wear. Continuous
monitoring gives maximum magnitude and directionof rod movement along with the crank angle at which
the maximum occurs. The source of movement canbe identified, enabling the proactive scheduling ofmaintenance for rider band replacement or crosshead repair. Monitoring the piston
rod vibration provides early warning for rod break. Monitoring the plunger position in
hyper compressors provides protection against deteriorating plungers.

3500 Monitor: 3500/72M Four-Channel Rod Position Monitor
Transducer: 3300XL Series Proximity Transducer
6. Multi-event Keyphasor signal

A proximity probe observing a multi-toothed wheel on the crankshaft provides aprecise reference timing signal every 30 degrees of rotation in comparison to aonce-per-turn reference point. The torsional vibration of the crankshaft changes
from revolution to revolution for each load step on the machine. Having multiple
events per revolution improves the ability of the system to capture data with respect
to crank position, regardless of the shape or change in shape of the torsional
vibration. This allows measurements such as rod position and cylinder pressure to
be correlated with a highly accurate crank angle measurement. Rod position canbe captured at the same point in the piston rod stroke, and cylinder volume can becomputed precisely at each point in the stroke for highly accurate P-V curves.

Suction gas temperatureContinuous monitoring of suction gas temperature provides a useful baseline
against which to compare suction valve temperature. Relative changes intemperature between suction valves and suction gas can give an indication of worn
suction valves. In addition, suction gas temperature, combined with the integrated
equation of state engine in System 1 software, provides the information necessary to
calculate capacity at suction conditions and cylinder flow balance numbers.

Discharge gas temperatureContinuous monitoring of discharge gas temperature can give an indication of worn
valves, unloaders, excessive compression ratio, or insufficient cooling water.

Prime mover

Placing accelerometers on the cylinder monitors the opening and closing events ofthe valves. The impact-type waveform information can be combined with cylinderpressure data to assess the health of the cylinder valves. Valve related malfunctions
such as loose valve cover bolts, valve fluttering, or capacity control malfunctions
can be detected. For hyper compressors, the cylinder acceleration changes
significantly when valve springs break or valve seats wear out.

9. Pressure packing case temperatureContinuous monitoring of pressure packing temperature provides useful information
on developing problems related to the packing including excessive wear, insufficientcooling, and inadequate lubrication.

Packing vent line temperature
7. Suction/discharge valve temperature

Suction and discharge valves are typically the highest maintenance items onrecips. Faulty valves can significantly reduce the compressor’s efficiency aswell as increase combined rod load. By recompressing the same gas, a leaky
valve becomes hotter than normal, causing the valve cover plate temperature
to increase. By monitoring both absolute valve temperature and differential
temperature between a group of valves, valve problems can be spotted early andrepaired before efficiency losses mount.

Continuous monitoring of the vent line provides an indication of leaking pressure
packing. With an increase in process flow, the vent line becomes hotter. For years,
operators have used the subjective method of touching the line to see if gas
is leaking.

Cylinder pressure—where the action is
The single most important measurement
for condition monitoring of reciprocating
compressors is cylinder pressure. Armedwith accurate cylinder pressure at eachpoint in the piston’s stroke, a PressureVolume (PV) curve can be constructed toprovide indispensable information on yourmachine’s health.

That’s why we’ve given particular attention tothis vital measurement. With a robust sensor,
advanced signal processing functionality
in our 3500/77M recip cylinder pressure
monitor, and a suite of plots in System 1

Pressure ports

BakerHughes_BN_ReciprocatingCompressorsMonitoring_Brochure-Print-NA-022324.indd 8

software, specifically for analyzing cylinderconditions, there’s simply no better way to
get inside your cylinders—where the action is.
Historically, measuring these conditions
meant temporarily attaching transducers
to isolation valves on each cylinder.
Although cumbersome, this practice wasnecessary because pressure transducers
simply couldn’t survive under long-term
exposure to the harsh environment ofcylinder chambers. We knew that thekey to reliable and effective assessmentof machinery health—not to mention
convenience—was to design a sensor that
could endure 24/7 exposure to such anenvironment, eliminating the burden of
constantly connecting and disconnecting
every time you wanted data.

With our proven Bently Nevada 165855
cylinder pressure transducer, we’ve done
just that. It provides continuous static anddynamic pressure data and is specificallydesigned for use with our 3500/77M recip
cylinder pressure monitor. Innovative
materials and construction techniques
allow it to deliver reliable measurementsin the extreme temperatures, pressure
cycling, and harsh chemical environments(such as H2S) inherent in reciprocating
compressor cylinder applications.

Available in a variety of pressure ranges from100 psia to 10,000 psia (68947 kPa/689 bar),the 165855 has undergone extensive testing.
In fact, we’re so confident of its performancethat we offer something unique to theindustry: a three-year warranty.

Decision Support: enhanced insights

Decision Support contains a collection ofproven Bently Nevada machine condition
monitoring analytics engineered to provide
a variety of insights. Configured property rules can beadapted to suit the unique operational characteristics
specific to a machine or asset. Extractions provide a setof rules that combine different measurements, statuses,
reference values and machine properties which can befurther used to evaluate the behavior of the reciprocating
compressor and can be used in developing custom rules.

In addition to packaged algorithms, Decision Support
allows users to create and deploy custom rules that help
you capture, disseminate, and leverage knowledge of yourequipment, processes, and business solutions. Custom rules
preserve operational knowledge in a useable format that canbe broadly applied in an easily repeatable and manageableway. You want to trend the total horsepower delivered byyour compressor? No problem; a simple custom rule can be
written to sum all the chambers’ Indicated Horsepowers andcan provide you with a trendable value. Further, this trended
variable can be used for comparison with frame rating to
identify overload conditions.
Decision Support InsightPak™ Analytics provide early
detection of failure modes associated with machine, process
and auxiliaries. The application acquires logic rules and feeds
the results back to System 1 for notification, visualization androot-cause diagnostics. For
example; Decision Support
can detect gas leakthrough packing rings andcan provide notifications
on System 1 and via emails
once the pressure packing
temperature case/ventratio extractions exceed
beyond pre-defined
threshold levels within
configured property
of pressure packing
limit constants.

Pressure versus displaced volume—PV plot

Rod load plot

Log PV

Pressure versus crank angle (θ-Theta)—PT plots

Plotting indicated and theoretical cylinder chamber pressure
versus displaced volume enables detection of malfunctioning
seals (rings, valves, and unloaders). A patented algorithm also
smartly draws the theoretical compression curve when steplessunloaders are used as the software detects the valve closure point
and adjusts the theoretical curves in real time. Multiple reference
samples can be stored and configured for display with yourcurrent values too.

Plotting PV curves on a logarithmic scale makes valve and piston
ring leaks more apparent to the diagnostic user.

Cylinder pressure is used to calculate total gas force. This is added
to the inertia force of the reciprocating components to calculate
combined rod load, and all three are plotted against the crankangle. Peak rod load compression and peak rod load tension areused to ensure overload conditions are not present for the throw.
Additionally, the crossing points of the combined rod load curve
across the 0 force axis determines the degrees of rod reversal,
which is an indicator of adequate lubrication in the crosshead
pin area. This plot shows a partially loaded condition (solid lines)
overlaid with a baseline fully‑loaded condition (dashed lines).

The crank angle domain is another useful format. Any timing
issues, as well as cylinder trim conditions, can be readily identified
using this view. Simply double-clicking on the units of thehorizontal scale of the PT plot shown here conveniently toggles
between it and the PV plot shown in the upper left and vice versa.

Rod position plots

Rod position plots display the total movement of the plunger
or piston rod at the pressure packing case. Typically, effects ofchanges in mechanical clearances, such as plunger to guidebearing, crosshead-to-crosshead guide, etc., and changes inaverage position, such as the thermal growth of a piston from cold
to operating conditions can be seen in this format. In this example,
the reference curves reflect a progression away from the bore
center over a seven week period.

Variables in crank angle domain

Leveraging the 3500 Series architecture, which simultaneously
captures data across multiple channels, this plot format enables
users to correlate events across different measurements and tocorrelate events with piston position inside the cylinder. Piston
rod monitoring can be represented in eight crank angle bands of
45 degrees width for each revolution with the maximum amplitude
shown for each 45-degree band.

For any plot the headers can be collapsed for maximum plot
viewing area.

Crosshead and cylinder vibration can be represented in 36 crankangle bands of ten degrees width for each revolution for both thefiltered and unfiltered waveforms with the maximum amplitude
shown for each 10-degree band.

Variables in crank angle domain—other views

The software allows plotting the waveforms from different
transducers in the same view. The plots below have the PT plot
(top view) with the crosshead acceleration and combine rod loadplot (bottom view) with the same crosshead vibration. Both views
show an example of a loose piston-to-piston rod connection.
The PT reveals the acceleration impacts at the points where thepressures cross in the expansion and compression curves andthe combined rod load reveals the acceleration impact eventsoccurring when the total gas force (blue curve here) crosses the
0 force line.

The software allows the diagnostic engineer to review the data on
a per throw basis or even looking at all the stages in one view asshown below.

Mechanical integrity

System 1 provides an intuitive user interface that enablesplotting of multiple measurements across events within a single
pane, facilitates efficient arrangement of multiple panes, andsynchronizes cursors and/or samples across panes. The plot
format incorporates graphics optimization algorithms to enhancedata presentation quality. This helps the user to more quickly andaccurately correlate events across multiple measurements.

Band waterfall plots

Trendable variables are configured for the impulse
acceleration channel to have 36 bands (10 degrees wide)
for both the filtered and unfiltered waveforms. These arethen graphically displayed in a band waterfall plot with acolor-contoured amplitude scale for easy viewing of amplitudechanges. This format allows the user to see how individual
events in the compression cycle behave over time and during
operational or process changes. The plot on the left showsan unfiltered crosshead Accel signal (3-20 kHz) that had apeak of 43 g’s towards the end. The filtered crosshead signal
on the right (3-2000 Hz) reveals the maximum value of 6 g pk
following an upward trend that began six days prior. The
obvious diagnosis was mechanical looseness, and a loose
suction valve cage with broken tie rods was discovered uponinspection after the shutdown.
