Abstract
The natural gas wellhead conditions vary over the life of a production well. These variations affect the performance, production and product quality of liquefied natural gas (LNG) plant. This study, through a simulation-based sensitivity analysis, highlights the significance of the effects imparted by the feed natural gas conditions on process performance of a propane precooled mixed refrigerant (C3MR) LNG process. The results show that the specific shaft work and thus OPEX is sensitive to the feed composition, flowrate, and pressure. For instance, as LNG production decreases from its design capacity of 3.0 MTPA to 2.4 MTPA over time, the specific OPEX increases from $128/t-LNG to $154/t-LNG.
