Improving Natural Gas Liquefaction Plant Performance with Process Analyzers

with high energy density, which makes it useful for storage and transportation over long distances from the gas fields to the consumers. LNG is recovered from natural gas in largescale liquefaction plants. Process automation is a key issue in LNG plants to ensure cost efficient plant operation and high product quality. Process analyzer deliver important data therefore. Siemens Sensors & Communication, a leader in process analytical instrumentation, has proven over decades its capability to plan, engineer, manufacture, implement and service analyzer systems for NG liquefaction plants. This Case Study provides an overview of the processes and describes how Siemens with its analyzer and application know-how meets best the process requirements. Liquefaction of natural gas to LNG
