Bearings for sour gas application.
No requirement for NACE due to no direct sour gas contact.
Meet and beat your sour gas and sulphur process safety and reliability.
Can be used in outdoor and ammonia(sour gas) environment.
The term/s acid gas and sour gas are often incorrectly treated as synonyms.
Thus, carbon dioxide by itself is an acid gas, not a sour gas.
Application example at a sour gas exploration site.
Thus, carbon dioxide by itself is an acid gas but not a sour gas.
Thus, the extraction and treatment of sour gas is subject to strict safety regulations.
Sour gas contains a high percentage(up to 25%) of hydrogen sulphide, which is extremely toxic and corrosive.
We understand the valve requirements and challenges of the sour gas and sulphur processing.
Stable, flexible and well-controlled sour gas and sulfur processing starts with selecting the right valves.
Alloy tubes are cold worked to high strength levels for downhole service in moderately corrosive deep sour gas.
Hydrogen sulfide is most commonly obtained by its separation from sour gas, which is natural gas with high content of H 2S.
Sea-water-cooled heat exchangers; offshore product piping systems;tubes and components in sour gas service.
Any excess gas from the gas separator vessel joins the sour gas from the stripping of the reaction product liquid.
The higher levels of chromium also provide excellent corrosion and oxidation resistance,which is a must in sour gas applications.
Sour gas is natural gas or any other gas containing significant amounts of hydrogen sulfide H2S.
Co2 for chemical synthesis is capable of generating value-added products andcontribute to a reduced release of this sour gas into the atmosphere.
Because of high sour gas content, a continuous control of the injection rate of ethylamine into the risers to avoid sulphur crystallisation is crucial.
In addition to being toxic, hydrogen sulfide in the presence of water also damages piping andother equipment handling sour gas by sulfide stress cracking.
The process steps for the purification of raw natural gas extend from separation, sour gas treatment, gas dehydration, NGL capturing up to final compression into the gas pipeline grid.
Strictly speaking, a sour gas is any gas that specifically contains hydrogen sulfide in significant amounts; an acid gas is any gas that contains significant amounts of acidic gases such as carbon dioxide(CO2) or hydrogen sulfide.
Likewise, an unexpected change in the gas composition, such as excessive carbon dioxide orhydrogen sulfide, sour gas, can cause dangerous problems.
That sour gas is sent to the refinery's central gas processing plant for removal of the hydrogen sulfide in the refinery's main amine gas treating unit and through a series of distillation towers for recovery of propane, butane and pentane or heavier components.
It also restricts the materials that can be used for piping andother equipment for handling sour gas, as many metals are sensitive to sulfide stress cracking.
Hsla steels exposed to environments containing co2 and h2s(sour gas) suffer general corrosion that promotes the diffusion of atomic hydrogen into the metal structure, which may decrease its toughness and induce cracks by the presence of hydrogen(hydrogen induced cracking- hic), leading the material to severe failures.
But, valve selection for control and isolation within the sour gas plant and sulfur recovery unit is about more than just efficiency and profitability- valve leaking and fugitive emissions must be prevented since such failures would create serious environmental and safety risks.
Although the terms"acid gas" and"sour gas" are sometimes used interchangeably, strictly speaking, a sour gas is any gas that specifically contains hydrogen sulfide in significant amounts, whereas an acid gas is any gas that contains significant amounts of acidic gases such as carbon dioxide(CO2) or hydrogen sulfide.
