A generalized disjunctive programming model for multi-stage compression for natural gas liquefaction processes [PDF]

E3S Web of Conferences, 2023
The primary driver of operating costs in natural gas processes is the energy consumption of the compression system. Multistage compression configurations are commonly employed and hence play a vital role in optimization of natural gas processes.
