Cracked gas composition

WebThe composition of the cracked gas with methane and naphtha and the plant feed and energy requirements are given in Table 9. The overall yield of acetylene based on methane is about 24% (14). A single burner with methane produces 25 t/d and with naphtha or LPG produces 30 t/d. The acetylene is purified by means of /V-methy1pyrro1idinone. [Pg.387] WebThe composition of the the products depends crucially on the feedstock used. For example, a much higher proportion of ethene to other products is formed from ethane and propane than from other feedstocks. ...
