Study on the Absorption Processing Technology of Ethyl Acetate

Abstract: Now days people increasingly pay attention to environmental protection, so using high-grade solvents in paint and ink production is the general trend. As the country’s economic sustained growth, construction、automobile and other industries rapidly development, it will drive more and more demand on ethyl acetate which was considered a high-grade solvent. This article explore an economical and effective method to recycle ethyl acetate by experiments, thus decrease industrial production costs and reduce environmental pollution when ethyl acetate solvent used in industry and  reduce the waste of resources. Design a technical improvement to overcome the shortcomings of traditional absorption, develop a new type of cleaning technology of recycling ethyl acetate exhaust and design process. Experimental determination of the efficiency of absorption is 90%, Henry coefficient is 1.59, so calculate and design the high of tower is 8.6 meters.

Keywords：ethyl acetate; absorption; process design
