Process qas chromatography: Avoid the iceberg of hidden expenses

摘要

Process gas chromatographs (GCs) are the most common multi-component, online chemical analyzer used in modern hydrocarbon processing industry (HPI) facilities-refineries, petrochemical plants and natural gas sites. GCs are proven and can provide data to control processes, supervise product quality and monitor facility emissions. Historically, GCs were placed in shelters that provided a stable temperature environment and a clean work area for operation and maintenance periods.To ensure optimal performance and reduce sample lag time- the time required for a sample to travel from the sample tap to the GC-the shelters were often located in areas classified as hazardous by industry codes and standards. Also, the space for the GC and shelter was not always available in close proximity to the process line being sampled.
