Manage contaminants in LNG feed gas and cryogenic processing—Part 2

The process of treating and liquefying natural gas into LNG is a complex and often delicate operation. LNG production is growing rapidly to meet demand, and processing facilities are highly profitable when designed and operated correctly. The profitability of a plant depends on throughput, which is maximized by maintaining stable operation, consistently meeting product specifications and identifying and managing contamination. These goals must be met in several systems throughout the LNG process. Part 1 of this article reviewed requirements for contamination management, common issues in LNG processing and feed gas contamination. Part 2 presents a case study to demonstrate how proactive cont
