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…
Developed by Allied Chemical Company, this process is selective toward removing sulfur compounds. Levels of CO2 can be reduced by approximately 85%. This process may…
This fraction is usually the first side stream of a conventional atmospheric distillation unit. It may be cut to meet a burning oil specification or…
This is the bottom product from the atmospheric distillation of the crude oil. Most crude oils are distilled in the atmospheric crude oil tower to…
For sizing a horizontal three-phase separator it is necessary to specify a vessel diameter and a seam-to-seam vessel length. The gas capacity and retention time…
Foam at the interface may occur when gas bubbles are liberated from the liquid. This foam can be stabilized with the addition of chemicals at…
A fixed bed of solid particles can be used to remove acid gases either through chemical reactions or ionic bonding. Typically, in solid bed absorption…
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…
Shell-and-tube heat exchangers are cylindrical in shape, consisting of a bundle of parallel tubes surrounded by an outer casing (shell). Both the tube bundle and…
The principal items of construction that should be present in a good liquid-gas separator are the same regardless of the over-al1 shape or configuration of…
