process selection of acid treating processes

An expert system to select acid gas treating processes for

An expert system was developed to select near-optimum acid gas treating processes in natural gas processing plants using heuristic knowledge from experts and literature. The near-optimum processes are defined as highly applicable processes for given conditions.

Acid Gas Treating Process Selection Hydrocarbon Compression

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 should be considered: 1. The type of acid contaminants present in the gas stream. 2. The concentrations of each contaminant and degree of removal desired. 3.

PROCESS SIMULATION AND IMPROVEMENT OF

Acid gas removal process, which is also known as gas sweetening process, is a very important industrial operation that has been described in many works. The main processes installed are based on absorption, and the selection of the solvent is based on its capability to absorb or remove acid gases such as carbon dioxide (CO2)

Acid Gas Removal FSC 432: Petroleum Refining

The rich solution containing the acid gases is sent to a flash drum to recover the C 1 and C 2 hydrocarbons from the rich solution to be used as fuel gas in the refinery to generate process heat, or steam in fired furnaces. The rich solvent is then sent to a regenerator still to remove the acid gases that are sent to the sulfur recovery unit.

Wet sulfuric acid process Wikipedia

The wet sulfuric acid process (WSA process) is one of the key gas desulfurization processes on the market today. Since the Danish catalyst company Haldor Topsoe introduced and patented this technology in the late 1980s, it has been recognised as an efficient process for recovering sulfur from various process gases in the form of commercial quality sulfuric acid (H 2 SO 4), with simultaneous

Treating Processes

Treating Processes Thioalcohols or thiols, more commonoly known as mercaptans, are a family of organic sulfur compounds present in a wide variety of untreated petroleum distillates, such as LPG, naphtha, kerosene, and gas oils. Specific mercaptans found in petroleum distillates originate in the crude or may form during subsequent crude refining.

The treatment must be compatible with the material of construction of the equipment and safe to use. The foulant (Unwanted material on solid surfaces) must show sufficient solubility in the treatment selected so when it is considered together with any insoluble matter that may reasonably be expected to detach fully during the process, it will achieve the desired degree of cleaning.
