Methanol is emitted from Oxygenated Gasoline Storage Tanks. Tank emission information is taken from the quarterly report file, VOC.xls. All the information below comes from the Tk_calc tab of that spreadsheet. E methanol Vmet VPmet ( Evoc , tpy) 2000 100 VPavg VPmet was obtained using Antoines equation. Antoine's coefficients A Methanol 7.897 B 1474.08 C 229.13 MW 32 Methanol is formed as a byproduct in the hydrogen plants. Process literature shows 70 ppm, wt. of methanol in the condensate streams. Assume all methanol is released to air during the process. From Burton Tredway - ext 1797. There are two H2 plants. 1 and 2. Condensate streams from both are measured. methanol formed lb / hr (condensate lb / hr ) 70 / 1000000 methanol formed lb / hr methanol lb / H 2 lb H 2 formed per hour methanol released Mlb ( H 2 production MSCF / yr ) ( h 2 , lb / SCF ) (methanol lb / H 2 lb) data : condensate formation rate H2 formation rate H2 production rate Controlled (monitored) equipment leaks are calculated via Correlation Equations which use real monitoring data to calc emissions. Fugitive emission data managment software (ORR-Leak DAS) helps calculate these emissions. Bev Kiecker is the contact for these calculations. Speciation data was added to the software for 1996RY, and this data is located in "Fugitive Speciation in LeakDAS.xls". The results are listed in LEAKDAS99.xls. The summed results are listed below. The maintenance fugitives were calculated based on bulk issued amounts of SARA compounds and mixtures containing SARA compounds for the reporting year. It was assumed that all bulk amounts issued from the warehouse were actually used. A list of materials containing SARA compounds (as well as a list of materials that do not contain SARA compounds) is located in "96KRCMaint.xls". For mixtures containing at least one SARA listed compound, MSDS information was used to calculate the mass of each SARA compound present in the mixture. In all cases, estimates were conservatively based on the upper end of the composition range given in the MSDS. Fugitive emission rates from maintenance activities were assumed to be directly related to chemical vapor pressure. A high vapor pressure chemical vaporizes much more quickly in an open space than a low vapor pressure one, so higher emission rates were assumed for higher vapor pressure chemicals. To determine emissions from Maintenance, need to know the amounts of materials containing SARA reportable compounds that were used this reporting year. Asked Steve Heiniger (x0583) to write a query in Impac to determine the amount of materials issued this reporting year. Assume that the amount issued is the same amount used for that reporting year. Take this electronic data and determine which contain SARA reportable compounds and which do not. Use data in 99IMPAC.xls which contains information to help make this determination. Also, if the item was not issued in '99, it may be in KEH's list copied into 99IMPAC.xls in the tab called "KEH Doc for SARA Lab&Maint". If data is not available here, then check the vendor MSDS's in safety (currently filed in Dewey Goulson's office).
