Nitrogen Rejection Process

A Nitrogen Rejection Unit is used to remove nitrogen from natural gas to increase the heating value of the gas. This process is generally involved cryogenic distillation to separate nitrogen gas from liquefied natural gas. The below process flow diagram illustrates the nitrogen rejection process. The design may vary from Read more…

n-methyl-2-pyrrolidone

It is a colorless liquid, although impure samples can appear yellow, and miscible in water. It is generally used in the petrochemical and plastics industries as a solvent, exploiting its nonvolatility and ability to dissolve diverse materials. CAS no: 872-50-4 Properties Generic Properties Critical Properties Temperature Dependent Properties Specific Heat Read more…

Natural Gas Sampling

Natural gas sampling is commonly used to secure a representative sample of produced gas for a specific period of time. To truly represent the varying composition stream, the more often sampling is required. The sampling system commonly consists of: Sample probe Connecting tubing Sample containers Sample valve Heat tracing and Read more…
