Petrochem Products Project Profile
An expansion project to build a large capacity urea plant and make improvements to the existing urea and ammonia plants included adding a Subpart Db Boiler.
The driver for this installation was an expansion project to build a large capacity urea plant and make improvements to the existing urea and ammonia plants. Construction of a new 450 MMBTUH boiler to support the expansion was part of the project. The facility was also getting modern smart analyzers and there was a need for PI data to go into the DAS as well. The facility falls under Oklahoma Department of Environmental Quality (ODEQ) regulation. The boiler falls under NSPS Subpart Db, but the state permit is overall more restrictive than Db. There were specific requirements from the state for both the CEMS and data management.
