Acid Gas Removal
HP Industry Perspectives: Is it too early to be optimistic for 2014?
The increased availability of natural gas supplies are redefining energy conditions. New natural gas reserves are shifting the order for producing nations. Shale gas reserves, once difficult to extrac..
Mitigate fouling in crude unit overhead—Part 1
In a refinery crude distillation column, up to 40% of the total heat removal may be found in the tower overhead condenser. The quantity of duty available makes heat integration (HI) between the column..
Improved oxidation process increases sulfur recovery with Claus unit
Since its development in 1936, the “modified Claus” technology has been the preferred process used by refineries and gas processing plants for the recovery of sulfur from acid-gas streams. M..
Evaluate surfactants as antifoam substitutes in amine systems
The handling capacity of gas sweetening plants using amine solutions is greatly affected by foaming problems. To mitigate foaming problems, antifoam is injected into the amine recirculating system at Oil and Natural Gas Corp.'s Uran refinery in India.

Tune up the ‘sweetening’ process for your facility
Novel catalysts can improve the oxidation of thiols (RSH) found in light oils. Thiols in petroleum products, such as liquefied petroleum gas (LPG) and light straight-run naphtha (LSRN), usually found ..
HP Viewpoint: Consider integral-gear compressors in CO2 services
In 1998, the author began researching suitable technology for compressing 95 MMSCFD of “bone dry” (–100°F dew point) carbon dioxide (CO2) from 16.7 psia to 2,710 psia. The compress..
