What are alanedial/alane triol?
Thread Content
What are alkanedi/alkanetri? It might be a very simple question, but I, as a layperson, don’t know the answer. Also, the material used for the tower body and its internal components in tower C407 is carbon steel; is heat treatment required during the manufacturing of the tower body? Thank you!
Alkanedi? Alkane tri? Is it ethane and propane? Steel definitely needs to undergo heat treatment.
I study chemical engineering. The term “alkanedialkane tri” isn’t the standard term, but I can give you an answer based on its literal meaning: Petroleum hydrocarbons are generally divided into alkanes, cycloalkanes, alkenes, and aromatics. . . Alkanes and cycloalkanes generally belong to saturated hydrocarbons. . . Olefins and aromatics are both unsaturated hydrocarbons. . . C407 may be the number of a tower in a certain gas separation process. . . The original poster mentioned alkanediols and alkanotriols; these can be simply referred to as carbon diols and carbon triols. . . In the case of towers used in gas fractionation units, given that the hazard level of such units is classified as Class A, the manufacturing requirements for their towers, heat exchangers, and containers are generally quite high. Moreover, corrosive acidic gases such as hydrogen sulfide are often present; therefore, regardless of the material chosen, it is essential to carry out heat treatment on those areas subject to welding stresses. . . :lol
I’ve never heard of the terms alkandie and alkantri; are they terms used by some old scholars? What is C407 used for? What are its medium and operating conditions? Please provide more details, OP.
I’ve really never heard of the terms alkadiene or alkatriene; do they refer to ethane and propane?
Tower C407 is the last unit in the alkylation and fractionation process of the alkylbenzene plant; it is known as the alkylbenzene recovery tower. It contains no HF or hydrogen sulfide, and all of its components are made of carbon steel. I’m not sure whether it refers to ethane or propane
Oh, if there is no exposure to hydrogen sulfide or similar substances, then there is no need to require heat treatment. . . :lol
You’d better ask the design engineer in the process field who commissioned you for the design to see if that term refers to ethane or propane. . . In alkylation units, the main components of the gas released from the tower top are hydrocarbon gases such as ethane and propane, which are basically non-corrosive. . . :lol
If the sulfur content is high, heat treatment is necessary for safety reasons.
I already know the answer; this question is incorrect. “Alkylbenzene Plant 2, Plant 3” is not a chemical term but rather the name of factories. There is also Alkylbenzene Plant 1, located in Nanjing. Thank you to all those who have offered their help!
I see; I even asked a few experienced workers, and none of them had heard of that term. I’ve learned it.* .
