What does “conversion” mean in chemical plants?
Thread Content
The term “conversion” is often seen in the chemical industry; I’m not sure what it means or what purpose it serves. I would appreciate it if an expert could provide an explanation! This post was last edited by yfq4308 on 2009-3-2 08:24]
This type of transformation is commonly found in ammonia and methanol production facilities; its main purpose is to convert harmful components into useful ones, such as converting organic sulfur into inorganic sulfur, and converting CO into CO2
This transformation is used in both ammonia and methanol production processes, primarily to convert CO and water vapor into CO2 and H2.
The transformation is used in both ammonia and methanol production processes; it primarily converts CO and water vapor into CO2 and H2 under high temperature and pressure, with the aid of a catalyst. CO+H2O=CO2+H2
In H2 production processes such as gasification and hydrocarbon steam reforming, large amounts of CO are generated. If CO is not required in subsequent steps, it must be removed through a reaction; since CO is difficult to remove, industrially, water vapor reacts with CO in the presence of an iron catalyst to produce H2 and CO2, which is easier to remove. (Of course, combustion is the best method, but it also destroys the useful hydrogen gas.) This process is known as \"shift reaction\".
In the chemical industry, conversion refers to the transformation of CO into CO2 and the release of H2 from water vapor. The purpose of doing this is to adjust the ratio of CO to H2 in the syngas. It is present in the ammonia and methanol production processes. The catalysts used are iron-based or cobalt-molybdenum-based. It is divided into sulfur-intolerant shift and sulfur-tolerant shift.
Function of the transformation: It converts carbon monoxide in the feed gas into useful hydrogen through chemical reactions, turning waste into a valuable resource (carbon monoxide is a harmful gas not required in the ammonia synthesis process).
The transformation involves converting the CO in the feed gas into CO2 through a chemical reaction; the specific chemical reaction is: CO + H2O = CO2 + H2
Adjust the hydrocarbon ratio to achieve optimal results!
