Project Summaries for Chemical Facilities
Client: Chemicals Manufacturer – Emission Source: Thermal Oxidizer
An emission compliance test program was performed in evaluation of a thermal oxidizer and wet scrubber system associated with a pilot plant chemical processing facility. The total hydrocarbon removal efficiency was determined by EPA Method 25A in conjunction with mass balance data. Hydrogen chloride and carbon monoxide emissions were also determined concurrently at the control system outlet utilizing EPA Method 26A and 10.
Client: Chemicals Manufacturer – Emission Source: Batch Reactors
AirNova, Inc. conducted an emission test program to determine compliance with state regulatory limits for an organic compound manufacturing process. The process incorporates a series of raw material reactor vessels, receivers, and storage tanks which are vented to a caustic venturi scrubber system for emission control. Total volatile organic compound concentrations and emission rates were determined at the scrubber outlet utilizing EPA Reference Methods 1, 3A, 4, 18, 25A, and ASTM D3464.
Client: Specialty Chemicals Manufacturer – Emission Source: Spray Dryer
An evaluation test program was performed to assess emissions resulting from a product spray dryer system operating under modified processing scenario. Emission sampling was performed downstream of a cyclone, baghouse and wet scrubber control system in determination of concentrations and mass rates of ammonia. Emission determinations were performed in accordance with EPA Reference Methods 1, 2, 3A, 4 and 206.
Client: Chemicals and Plastics Manufacturer – Emission Source: Product Spray Dryer
Emission sampling was conducted at the outlet of a spray dryer and fabric filter control system in determination of phenols, formaldehyde, particulate, sulfur dioxide and nitrogen oxides. EPA Reference Methods 5, 6 and 7E were utilized for this purpose in addition to BIF Method 0011A and TO-8.
