Two-stage Isobutylene Recovery Compressor Package
We just completed this two-stage Isobutylene recovery compressor package for Monument Chemical in Houston. The system uses a BLACKMER® NGH1023 6X3.25 two-stage, oil-free reciprocating compressor to recover IB down to 0 psig from an upstream process reactor. Due to the high gas temps, we included a custom designed inlet cooler to manage the inlet gas temps while ensuring there was no condensation. Because of trace levels of H2S, corrosion and leakage were a concern. We used all 316SS piping, welded bellows sealed valves and 316SS vessels. It includes Endress+Hauser instrumentation and meets Class 1, Div.II electrical requirements.
