Which of the deep-processing products of dichloroethane in the VCM distillation residues is the most economically viable?
Thread Content
Dichloroethane is mainly used in the production of VCM, but in PVC manufacturing plants, it is used in small quantities as an EDC. The investment required for its use in the decomposition process to produce VCM is high, making it uneconomical. In addition to producing VCM, it can also be used to manufacture chlorinated solvents such as trichloroethylene, ethylamine, vinyl chloride, and trichloroethane. It is also employed as an intermediate in the production of tetrachloroethylene and as a catalyst for the production of hexachlorophenolmethane. Does anyone knowledgeable know which products offer relatively good economic returns? This post was last edited by shizhiyong001 on 2009-2-17 08:59
Our company sells dichloroethane to customers; it is said to be used in waterproof coatings, but I’m not entirely sure about the details.
We sell it here as well; although the price isn’t high, it seems to sell quite well. At the moment, our selling price is around 800 yuan per ton.
800 yuan per ton is way too low. I’ve seen online quotes for dichloroethane at 3,000–4,000 yuan per ton; if we purify it, the profits should be considerable
We also sell the distillation residues to some small factories; it is said that they purify them through simple distillation for use as solvents, and the returns are quite good
