Resolving Design Challenges
Many small-scale LNG plants use the two-stage single mixed-refrigerant compressor or the nitrogen expander technology.
Its typical design presents challenges. These include molecular weight variations and lack of non-return valves.
However, it’s possible to re-design the piping layout of the typical single mixed-refrigerant compressor so that it is compatible with good anti-surge control requirements.
We lay out typical compressor design, its challenges and how to resolve them.
