Sour Gas Processing Facility

Compression & Process

This Startec-designed mechanical refrigeration unit (MRU) is one of the largest single-train units built in western Canada. 

Always searching for a better way, the Startec team provided an innovative design, which removes much of the water that is entrained in the gas due to sour processing by the amine plant. This design provided lower propane chiller and Ethylene Glycol injection duties, which offers significant savings on capital and operational expenses. The advanced design also allowed a compact plot plan layout so that, unlike most MRU’s, we were able to avoid mounting the very large gas/gas exchangers up high on large structural steel. This added to the economic savings and provided better operational access.
