Use a hierarchical process to evaluate sales gas compressor selection

S. Zardynezhad, Wood Group Mustang, Calgary, Canada Compressors are key equipment pieces in gas processing projects because they are long-lead delivery items that require the allocation of a significant portion of the budget, and their performance significantly affects operating expenditures (OPEX).
