Most companies have a detailed general specification for the construction of pressure vessels, which defines the overall quality of fabrication required and addresses specific items…
Coalescing of the small water drops dispersed in the crude can be accomplished by subjecting the water-in-oil emulsion to a high-voltage electrical field. When a…
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…
This is not strictly a cut but consists of all the light material in the crude absorbed into the total overhead distillate from the crude…
Two common internals not discussed are coalescing plates and sand jets. It is possible to use various plate or pipe coalescer designs to aid in…
Liquid carryover and gas blowby are two common operating problems. Liquid carryover occurs when free liquid escapes with the gas phase and can indicate high…
Balanced relief valves are spring-loaded valves that contain a bellows arrangement to keep back-pressure from affecting the set point. Figure 13-4 shows a cross section…
For an oil and gas separator to accomplish its primary functions, pressure must be maintained in the separator so that the liquid and gas can…
The process of coalescence in water treating systems is more time dependent than the process of dispersion. In dispersions of two immiscible liquids, immediate coalescence…
Hydrocarbon streams as produced at the wellhead are composed of a mixture of gas, liquid hydrocarbons, and sometimes free water. In most cases it is…
