Achieve three efficiencies in MR compressors for SSLNG

In the equipment they use, investors in small-scale LNG (SSLNG) face a steep challenge: They must achieve cost efficiency, operational efficiency and energy efficiency—all with maximum availability. In this context, the design of single mixed-refrigerant (SMR) compressors, a critical piece of technology in SSLNG plants, takes on an important role in both the plant’s efficiency and its return on investment (ROI). As the benefits of integrally geared compressors (IGCs) have become better known across hydrocarbon processing industries, this compressor type has achieved broader acceptance. For SSLNG, this pertains particularly to compressors requiring gas or electric drives with a rated power o
