Reports from McMaster University Provide New Insights into Chemical Engineering

May 14, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- Research findings on Chemical Engineering are discussed in a new report. According to news reporting originating from Hamilton, Canada, by VerticalNews correspondents, research stated, "In this work, a semicontinuous system is investigated for the separation of biomass-derived dimethyl ether from a vapor-liquid mixture. This novel semicontinuous system operates in a cyclic campaign and utilizes one partial condenser column coupled with a middle vessel to achieve the separation typically carried out using two continuous distillation columns."

Our news editors obtained a quote from the research from McMaster University, "The performance of six control configurations based on composition or temperature inferential control were analyzed. Dynamic simulation results demonstrate the effectiveness of the semicontinuous system and its temperature inferential control configuration in achieving the separation objectives, remaining within operational limits and rejecting fresh feed disturbances."

According to the news editors, the research concluded: "Finally, the semicontinuous system is compared to the traditional continuous system from an economic standpoint with the sensitivity of operating cost to middle vessel product target purity highlighted."
