Process Design• Multiple train design (75 mmscfd, 0.5 mta) improves reliability & availability• Less equipment than SMR, DMR & Cascade = less cost, easier operation• Fits on LNG carrier (new / converted) or barges (steel or concrete)
Operations• Responds quickly to oil and gas field fluctuations• Handles variable gas feed rates and compositions• Turndown to zero, recycle flash gas keeps system cold• No cryogenic compression required, lower cost, shorter delivery• Proven gas plant components: compressors, expanders, brazed aluminum heat
exchangers, gas turbine or electric drives• Quick, warm startup. No long cool-down or refrigeration sequence• Insulated “cold box” keeps systems at temperature for several days
