When any source ,uses FGD equipment or another technology to control 802 emissions. either the fuel basis

must be used for the manufacturing and release oalculalions. or GEMS data can be used but only when the

Sulfuric: Acid Released from Combustion (ERComb)

For units that do not employ SCR or SNCR NOx control or FGC. the sUlfuric acid released is the product of the

Sulfuric Acid M~nufactureby SCR (EMSeR)

The following relationship estimales the total H2S04 manufactured from an SCA equipped utility boiler or steam

generator:

Equation 4-4 EMSCR = K· S2· fsops • E2' F3SCR

where,

EMSCR =Total H2S04 manufactured from SCA, lbs per year

K =Conversion factor =: 3063

S2 =: SeR catalyst S02 oxidation rate (specified as a decimal, typically from 0.001-

0.03)

fsops =Operating factor of SCR system. or the fraclion of coal burn when the flue gas is dIrected fhrough Ihe

SCR, whether NH3 reagent Is injected to derive NOx reduction or not. This value should reflect the hours the SCA

reactor processed flue gas, whi

E2 =S02 produced, tons per year

F3SCA =Technology Impact Factor, for SCR

An F3SCR factor for PAB coals is shown in Table 4-2. This factor is derived from measurements at two PRS-flred

units. S03emilted from these units was lower than specified in the catalyst guarantee, which was based on

laboratory test data. At present, the .

Sulfuric Acid Released fram SCR and SNCR

The sulfuric acid released .from SCR or SNCA is determined by subtracting from the sulfuric acid manufactured

the amount removed by the residual ammonia, or ammonia slip. For SCR, the sulfuric acid released (ERSCR) is

estimated with the following relations

Equation 4-5 EASCR::: [EMSCR - (Ks • B· fs-reagent· SNH3)]· F2x

where,

ERSCR =0 Tatar H2S04 released from SeR, Ibs per year

EMSCR == Total H2S04 manufactured from SCR, Ibs per year

fsreagent = fraction of seR operation with reagent injection, when residual NH3 is produced Ulat will remove

S03. The value of fsreagent will be similar to, but slightly less than, the value of fsops, defined for Equation 4-4.

SNH3 = NH3 slip from SCRlSNeR, ppmv at 6% 02, wet:

• SCR averages 0.75 ppmv over catalyst guarantee period

• SNCR averages 5 ppmv

• Nole: actual NH3 slip data shollld be used it available

F2x = Technology Impact Factors, all that. apply

The conversIon faclor Ks, equal to 3799, considers all relevant oonstants to yield the result in pounds per year of

sulfuric acid. The derivation of this constant. for the case where residual NH3 Is reported in terms of 6% oxygen

and "wer' flue gas at B.1

The coal burn rate in TBtulyr is. obtained from coal use reoards, such as those reported to ErA in Form 767. The

operating factor of the SCR describes lhe portion of the coal burn thai reflects the period of SCR operation, based

on whether Ihe unit operate

Accordingly, total sulfuric acid manufacture (TSAM) and release (TSAR) is estimated for agenerating unit

equ[pped with SeR and flue gas conditioning by the following equations:

Equation 4-11a: Manufacture

TSAM = EMComb + EMSCRlSNCR + EMFGC

Equation 4-11b: Release.

TSAR =ERComb + ERSCRISNCR + ERFGC
