The molecular weight of the stream is calculated from the weighted average gas molecular weight given by: The molecular weight of the gas stream of…
Coriolis mass-flow controllers (MFCs) are widely used in the chemical process industries (CPI) for applications that require precise and accurate measurement and control of critical…
This process uses propylene carbonate as a physical solvent to remove CO2 and H2S. Propylene carbonate also removes C2+ hydrocarbons, COS, SO2, CS2, and H2O…
A bed of structured packing consists of a bed support upon which elements of structured packing are placed. Beds of structured packing typically have lower…
The purpose of the gas separation section of the vessel is to condition the gas for final polishing by the mist extractor. From field experience…
For distillation services, as in condensate stabilization, tray design is well understood, and many engineers are more comfortable with trays than with packing. In the…
Figure 13-2 shows a cross section of a conventional relief valve and Figure 13-3 is a schematic that shows the valve’s operation. Convention al relief…
Tube holes cannot be drilled very close together, since this may structually weaken the tube sheet. The shortest distance between two adjacent tube holes is…
These are thin diaphragms held between flanges and calibrated to burst at a specified static inlet pressure. Unlike relief valves, rapture discs cannot reseal when…
Separator operation can be adversely affected by an accumulation of paraffin. Coalescing plates in the liquid section and mesh pad mist extractors in the gas…
