APPENOIX E REFERENCE HETHOOS AXO PROCEDURES ' Introduction This Appendix presents the reference Methods and procedures required for Implementing Reasonably Available Control Technology. (RACT). Methods and procedures are Identified for two types of ACT Implementation: . a) Oetermlnatlon.of.VOC destruction efficiency for evaluating..eompl lance with, the 98 weight percent VOC reduction of 20 ppmv emission limit specified In Sections 215.528 through 215.527: and b) Determination of offgas ilowrate. hourly emissions and stream net heating value for . calculating TRE.- .All reference methods Identified In this Appendix refer to the reference methods -i specified at 40 CFR 60. Appendix A; Incorporated by reference In Section 215.10S. VOC DESTRUCTION EFFICIENCY OETERHINATION The following reference methods and procedures are required for determining compliance with the percent destruction efficiency specified In Sections 215.520 through 215.527. a) Reference Hethod 1 or 1A for selection of the sampling site. The control device Inlet sampling site for determination of vent stream molar composition or total organic . compound destruction efficiency shall, be prior to the Inlet of any control device and after all recovery devices.. \ b) Reference Hethods 2. 2A.2C or 2D for determination of the volumetric flowrate. c) Reference Method 1 to measure oxygen concentration of the air dilution correction. The emission sample shall be corrected .to 3 percent oxygen. . d) Reference Hethod .18 to determine the . concentration of .total organic compounds . (oitr-js.'methane and ethane) In the control device outlet and total organic compound reduction efficiency of the control device. TRE DETERMINATION The following reference methods and procedures are required for determining the offgas flowrate, hourly emissions, and the net heating value of the gas combusted to calculate the vent stream TRE. a) Reference Hethod 1 or 1A for selection of the sampling site. The sampling site for the vent stream flowrate and molar composition determination prescribed in (b) and (c) shall be prior to the Inlet of any combustion device, prior to any post-reactor dilution of the stream with air and prior-to any post-reactor Introduction of halogenated compounds Into the vent stream. Subject to the preceding restrictions on the singling site, it shall be after the filial recovery device. If any gas stream other than the air oxidation vent stream' Is normally conducted through the recovery system of the affected facility, such stream'shall be rerouted or - turned off while the vent stream is sampled, but shall be routed normally prior to the measuring of the initial value of the mohitored parameters for determining compliance with the recomaended RACT. If the air oxidation vent stream Is normally routed thibugh'any equipment which is not a part of the air dxtdatlon process as defined in 35. 111. Ada. Code 211.122. such equipment shall be bypassed-by jtb*-vent stream-while- the vent stream is sampled, but shall not be bypassed during the measurement of the Initial value of the monitored parameters for determining ' compliance wlthrsubpart v; .' b) The molar composition of the vent stream shall be determined using the following methods: 1) Reference Hethod 18 to measure the concentration of all organics, including those containing halogens, unless a . rtgntMcawtrpcrrtton of the* compounds of -- Interest are polymeric (high molecular weight), can polymerize before analysis Or hive Tow vapor pressures T fn wffffch ease Reference Method 25(a) shall be used 2) Asm D1946-67 (reapproveM77>v Incorporated by reference In Section 215.105. to measure, the concentration of carbon monoxide and'hydrogen. 3) Reference Method 4 to measure the content of water vapor. If necessary. *c) The volumetric flowrate shall be determined using Reference Hethod 2. 2A, 2C or 20. as appropriate.' d) The net heating value of the vent stream ' shall be calculated'using -the- following -equation: n, H K 2 C1H1 lil Where: ... H. = Net heating value of the sample. HJ/scm. where the net enthalpy per mole of offgas Is based on combustion at 2SC and 760 nra Hg. but the standard temperature for determining the volume corresponding to one mole Is 20C. as in the definition of F (venLstream-tlowciLel.below- - 141
