The iron-sponge process generally uses a single vessel to contain the hydrated ferric oxide wood shavings. A drawing of an iron-sponge unit showing typical provisions…
Each of the previous treating processes has advantages relative to the others for certain applications; therefore, in selection of the appropriate process, the following facts…
Gas permeation is based on the mass transfer principles of gas diffusion through a permeable membrane. In its most basic form, a membrane separation system…
The Ryan-Holmes distillation process uses cryogenic distillation to remove acid gases from a gas stream. This process is applied to remove CO2 for LPG separation…
Sour gas sweetening may also be carried out continuously in the flowline by continuous injection of H^S scavengers, such as amine-aldehyde condensates. Contact time between…
The molecular sieve process uses synthetically manufactured solid crystalline zeolite in a dry bed to remove gas impurities. The crystalline structure of the solids provides…
The zinc oxide process is similar to the iron sponge process. It uses a solid bed of granular zinc oxide to react with the H2S…
SulfaTreatĀ® process is similar to the iron sponge process. It uses a patented proprietary mixture of ferric oxide and triferric oxide to react with H2O…
Next to sales contract specifications, corrosion protection ranks highest among the reasons for the removal of acid gases. The partial pressure of the acid gases…
