BAHXs are essential for cryogenic gas processing. Turboexpander A turboexpander, also referred to as a turbo expander or an expansion turbine, is a centrifugal or axial flow turbine, through which a high pressure gas is expanded to produce work that is often used to drive a compressor or generator.. Because work is extracted from the expanding high pressure gas, the expansion is approximated by an isentropic process (i.e., a constant entropy process), and ... Safe Design and Operation of a Cryogenic Air Separation Unit Technology for separating air into its primary components (oxygen, nitrogen & argon) by cryogenic distillation has been practiced for over 100 years. Figure 1 is a basic flow diagram for the separation of air by cryogenic distillation. Air is compressed in the Main Air pressor (MAC) to between 4 and 10 atm. TUTORIAL ON CRYOGENIC TURBOEXPANDERS product that is recovered as a result of the condensation process, making the plant more efficient. The amount of this liquid can vary from about zero to 50 percent of the inlet stream (weight percent age basis), depending on the process conditions. A typical process is shown in Figure 3. Figure 3. Typical Process Flow Diagram. Natural Gas Processing | FSC 432: Petroleum Refining Natural gas hydrates are crystalline ice like solids or semi solids that can impede the passage of natural gas through valves and pipes.
