A sustainable solution to reduce Europe’s reliance on natural gas

6/13/2023

This analysis shows that Europe will need to reduce natural gas demand by 55 Bm3 this year alone to mitigate against a potentially colder winter, a possible end to Russian supplies or rebounding Asian demand. This comes at a time when Europe has little bandwidth for additional energy rationing without sustaining a steeper slowdown in economic activity.

Take the mystery out of running your LNG plant

5/19/2023

While process simulation software can be used by plant engineers to calculate the dewpoint temperature of mixed refrigerant, this is of limited use to the plant operators at the control panel in maintaining an appropriate amount of mixed refrigerant superheat as they adjust the plant. To address these challenges, the authors’ company has developed a simplified method of calculating mixed refrigerant superheat that can be programmed in the distributed control system (DCS) and made available to panel operators.
