SUBJECT: Petroleum Refinery Sector Rule: Evalua tion of Flare Tip Velocity Requirements

I. Purpose

This memorandum documents the data review conducted regarding the flare tip velocity

requirements for petrol eum refinery flares.

II. Peer Review Comments Related to Flam e Liftoff and Flare Tip Velocity

In April 2012, the EPA released a technical report for peer revi ew ( EPA, 2012) that discussed

observations regarding the operation and performance of flares, incl uding trying to correlate flare

flame lift off with flare tip veloci ty. The report states that as the velocity increases, the flame

will eventually lift off from the tip of the flar e and progress to a condition where the flame will

become unstable and inconsistent, and in so me cases the flame can be extinguished.

Flare researchers have evaluated various equatio ns to determine operating conditions in which

the flare tip velocity is high enough to cause flam e lift off and instability. These equations and

researchers’ evaluations were referenced in the April 2012 tec hnical report, with the Shore

equation (Shore, 2007) receiving additional attenti on because the input parameters used in the

Shore equation are more readily available than so me of the input parameters used in the other

equations. The technical report stated that the data suggested that “... the actual flare tip velocity

(i.e., actual flare vent gas velocity plus center steam velocity, if applicable) should be less than

an established maximum allowable flare tip ve locity calculated usi ng an equation [Shore

equation] that is dependent on combustion zone gas composition, the flare tip diameter, density

of the flare vent gas, and density of air.”

As part of the peer review pr ocess, reviewers were asked to comment on whether the flare data

adequately supported these obs ervations; and whether there were other parameters or

methods/equations that should be given more or less emphasis. All of the peer reviewers

commented to some extent on this question, yet only one reviewer agreed with the agency’s

observations (Richardson Fry and Coburn, 2012). The rest of the peer review comments related

to this question can be summarized as follows:

 The equation that was developed by Shore (2007) cannot be adequately assessed or

validated due to lack of data at high flare tip velocities.

 The existing data is not adequate to a ssess whether the Shore equation offers any

advantages over the current flare tip ve locity equations in 40 CFR 60.18 and 40 CFR

# 2 63.11 (i.e., maximum flare tip velocity (Vmax) as a function of vent gas net heating

value (NHV)).

 One peer reviewer also argued that flam e liftoff does not automatically imply poor

combustion efficiency; however, the EPA already had acknowledged this observation

in the April 2012 technical report. 1



# Considering the first two bullets in the list above, it is tr ue that the Shore equation (and any other

parameters or methods/equations br iefly discussed in the technical report) cannot be examined to

the fullest extent because of the following reason s: (1) actual flame liftoff data is not available

for the passive fourier transform infrared (PFTIR) flare performance test data that EPA reviewed

in the technical report; and (2) all of the PFTIR flare performan ce tests are performed at very

high turndown ratios and conseque ntly, have relatively low flare tip velocities (all recent test

runs were performed at less than 10 feet per s econd) so validating any eq uation over a very large

range of possible flare tip velocities is not possible.

Given the narrow window of flar e tip velocities studied within the new test data and the

uncertainty of how well the Shore equation models fl are operation at a much larger range of flow

rates, as well as the fact that flame lift o ff does not always indica te poor combustion, it was

determined that not enough information was avai lable to validate the use of the Shore equation

or to show that the Shore equation is more effec tive than the existing flare tip velocity equations

at indicating flame stability at this time. Peer reviewers did not provi de suggestions for any

other equation or velocity monitoring techni que (although one peer revi ewer suggested that

detailed transient large eddy simulation based on computational fluid dynamics analyses are

required to monitor flame stability and a single parameter is not appropriate) (Richardson Fry

and Coburn, 2012). Therefore, the EPA decided to review the existi ng flare tip velocity

equations in 40 CFR 60.18(f)(5) and 63.11(b)(7)(iii) for steam-assist ed and non-assisted flares

and in 40 CFR 60.18(f)(6) and 63.11(b)(8) for air-a ssisted flares (herein referred to as the

General Provisions (GP) flar e tip velocity equations).

III. Flare Tip Velocity Equations for Stea m-Assisted and Non-Assisted Flares

In studying the correlation between flare flame stability and fl are tip velocity, several different

testing protocols were used by the EPA in the 1980’s to better understand their overall relation.

Many of the protocols involved observing the flare flame for signs of instability using various

flare designs and sizes. In reviewing the result s of the studies’, the EP A report “Evaluation of

Flare Efficiency of Industrial Flares: Test Results” (Pohl, J ., R. Payne, and J. Lee. 1984)

concluded:

“Figure 4-15 shows that at low velocities, st able flames could be obtained with gases of

heating values of approximately 300 Btu/ft 3 

# . However, high heating values of the gases

were required to stabilize the flares at higher velocities.”

This conclusion appears to be the basis for the development of the steam-assisted and nonassisted GP flare tip velocity equation. Figure 1 presents all of the data collected in the 1980’s

1 

### The April 2012 technical report stated that: “Flame stability can exist when flame lift off oc curs; however, as flame stabilit y

decreases (which can be caused by a variety of reasons, such as changes in flare tip velocity, combustion zone gas

composition, or wind direction and speed), a flare operating at flame lift off can progress to a condition where the flame is

extinguished; at a minimum, the flame will be in consistent (Kalghatgi, 1981a; and Shore, 2007).”

# 3 studies, prior to the development of the GP flare tip velocity equations (see Attachment 1 for all

data used to support this technical memorandum).

Figure 1. Summary plot of all data fr om the 1980’s flare efficiency tests



# Reviewing this plot, one can see the limits in the data available across the full range of velocities

and heating values of the gas being combusted in the flare. It should be noted that the maximum

velocity limits for non-assisted flares are depicted in Figure 1 a nd start at 200 Btu/ft 3 

# , then come

in line with the maximum velocity limits for steam-assisted flares, which start at 300

Btu/ft 3 

# (based on the current GP requirements 40 CFR 63.11(b) and 40 CFR 60.18(b)). There are

basically two groups of da ta, those near 300 Btu/ft 3 

# and those at about 1000 Btu/ft 3 

# and above. It

appears that the GP flare tip velocity equation for steam-assist ed and non-assisted flares was

derived by connecting the maximum velocities of these two data gr oupings with a straight line

(on a semi-log plot). In other words, c onnecting the point at approximately 300 Btu/ft 3 

# and 60

ft/sec with the point near 1000 Btu/ft 3 

# and 400 ft/sec on a semi-log scale and performing a linear

regression, establishes the equation that is included in General Provisions for steam-assisted and

non-assisted flares. This GP flar e tip velocity equation for thes e two flare types is shown in

Equation 1 (SI units) and Equati on 2 (English units) below. 0 50 100 150 200 250 300 350 400 450

IV. Flare Tip Velocity Equations for Air-Assisted Flares

The GP flare tip velocity equation for air-assist ed flares was also developed from a 1980s flare

efficiency study (McDaniel, M. 1983). Fi gure 2 below shows a plot of this data.

However, later Pohl and Soelberg (1985) evaluated the efficiency of flares considering flare head

design and gas composition. Including the data fr om Pohl and Soelberg (1985) with the data

from McDaniel (1983), it appears that a wider envelope of accep table flare velocities may be

appropriate (see Figure 3 below).

# 6 Figure 3. Plot of air-assisted test data from flare efficiency study (all air-assist data).



# V. Flare Tip Velocity Equations for Refinery Flares

As evidenced by the inclusion of the Pohl and Soelbe rg (1985) air-assisted fl are test data with the

data from McDaniel (1983) in Figure 3, it appe ars that a less stringent maximum velocity

requirement could be warranted for air-assisted flar es, especially when considering all data that

exceeds 98 percent combustion. In order to assess wh at this flare tip velo city requirement could

be for air-assisted flares opera ting at petroleum refineries, we first took all the data used to

generate the steam-assisted and non-assisted flare tip velocity requirements (see Figure 1) and

added to it all air-assisted flare test data fr om both Pohl and Soelberg (1985) and McDaniel

(1983) that meet the air-assisted NHV

cz 

# and NHV dil 

# criteria discussed in the memorandum

entitled “Petroleum Refinery Sector Rule: Operating Limits for Flares.” The results of this

analysis are presented in Figure 4 below. Since the air-assisted flare st able operating envelope

appears to be consistent with the stable operating envelope for steam- and non-assisted flares, it

appears reasonable to use a single flare tip ve locity equation (i.e., the logarithmic equation

historically used for steam- and non-assisted flares) for all petroleum refinery flares. 0 50 100 150 200 250 300 350 400 450
