Raw carbon four generally refers to the components remaining after the separation of carbon three from liquefied gas produced by catalytic cracking units through gas separation； High-olefin C4 mainly refers to the butylene resources generated as a by-product of coal chemical processing
Thank you; these two raw materials have a high sulfur content
High-olefin C4 generally contains no sulfur; it’s harder to say the same for C4 after etherification
The carbon tetra-sulfur content in the gas fractionation unit is generally kept at around 20 ppm; this depends on the sulfur content of the liquefied gas fed in
