Sweetening, dehydration, natural gas liquid (NGL) recovery, and sale gas compression are four major treatment stages for the general natural gas processing. Here, a comprehensive gas processing plant (CGPP) coupling sweetening, dehydration, NGL recovery, and compression subsystems have been conceptually designed, modeled, and optimized based on field data. The development includes four major stages of work: (i) CGPP process development with Aspen HYSYS simulator; (ii) sensitivity studies for all distillation columns involved in the CGPP process to optimize their performances; (iii) sizing of major equipment of the CGPP; and (iv) economic evaluations with Aspen process economic analyzer to calculate the expected capital and operating expenditures for the developed CGPP process. Valuable insights of natural gas monetization from the viewpoint of large‐scale process system integration, modeling, and optimization are provided.
