Summary This project uses butene component in the mixed C4 to produce MEK, which would improve the resource utilization of C4 and comprehensive economic benefits. The design size of mixed C4 feeding is 51000 tons/year, the production of methyl ethyl ketone is 40000 tons/year, while the production of byproduct includes tertiary butanol 1130 tons, crude sec-butyl alcohol 2960 tons, the heavy constituent 140 tons, hydrogen (≥98 wt %) 1100 tons, waste butene 2640 tons, butane 4500 tons. The total investment of the project construction is 520 million RMB. Ⅰ Technology Introduction The Choice of Raw Material Factory Site Selection The raw material, as instructed in the project specification, comes from the branch of Petroleum Refining, with purity of 89%wt. The branch will be located in the Qingdao Economic and Technological Development Zone, Shandong Province, relying on Sinopec Qingdao. Qingdao has plenty of material resources, well-developed transportation network and a cheaper labor market. With advantages above, we consider Qingdao as a quite ideal location for petrochemical industry. Process Overview The project selects the technology of butene hydration make up butanol, butanol gas hydrogen system make up methyl ethyl ketone, which will exchange catalyst for the high- temperature acid resin to produce butanol and use Copper and Zinc alloy catalyst (Model BC-DH2004) to produce methyl ethyl ketone. Innovations in Process The application of Yantai University extractive distillation separation of the carbon process Because of its contribution to Alkane and alkene relative volatility and low toxicity, the mixed solvents with MEK and N-formex testosterone is the best solvent for the separation of butane and butane. Improve the viscosity and surface tension of the solvent systems, the mass transfer efficiency and the heat transfer efficiency in extractive distillation column is improved, the foaming is reduced. operation stability; The egeneration of solvent will reduce
