Several proprietary processes have been developed based on the hot carbonate system with an activator or catalyst. These activators increase the performance of the hot…
Licensed by Shell the Sulfinol® process combines the properties of a physical and a chemical solvent. The Sulfinol solution consists of a mixture of sulfolane…
These processes are based on the solubility of the H2S and/or CO2 within the solvent, instead of on chemical reactions between the acid gas and…
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…
The German Lurgi Company and Linde A. G. developed the Rectisol® process to use methanol to sweeten natural gas. Due to the high vapor pressure…
A bed of random packing typically consists of a bed support (typically a gas injection support plate) upon which pieces of packing material are randomly…
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…
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…
For stripping service, as in a glycol or amine contactor , bubble cap trays are the most common. In recent years, there has been a…
