Project - Denison, Iowa Plant - Chemical Processing

Capacity: 100 mmBTU
An energy company owns and operates a combustion process at an ethanol processing facility in Denison, Iowa. The ethanol process combusts exclusively pipeline natural gas to drive a 100 mmBTU heat recovery steam generator (HRSG) for production of steam used in the distilling process. The exhaust gas stream is discharged to the atmosphere and emissions are monitored using a PEMS and a data acquisition system under the requirements of 40 CFR Part 60.

Federal Regulations promulgated in the New Source Performance Standards of 1974 are applicable to the unit. These regulations specify emission limitations for nitrogen oxides. The regulations require installation, calibration, maintenance, and operation of a data acquisition system for documentation and reporting of operating data and nitrogen oxides emission rates. Additional monitoring, record keeping, and reporting requirements are specified in the local operating permit (AQB IDNR).
