Fluid Handling: Ensure Satisfactory Sampling

Drawing representative streams from pressurized systems demands care

mn fluid handling sample

When accurate, online analyzers often give the best information on process compositions. However, such analyzers generally are expensive and delicate as well as time consuming and costly to maintain. So, plants tend to install a minimum number of them. Instead, most facilities send samples to a laboratory for monitoring and troubleshooting. Permanent sample installations with flow-through loops provide the most consistent method for gathering samples (see: “Get Valid Samples”). Flow-through loops also may be costly, though, and pose their own problems.Troubleshooting frequently requires taking samples from rarely used locations. Samples from pressurized systems…
