Summary: MEK is a promising bulk chemical with numerous applications, but its purification process faces challenges due to the formation of azeotropes. Therefore, a intensified process has been proposed to reduce the energy investment for MEK purification and replace traditional distillation methods. Comparison results showed that the intensified design performed excellently in terms of energy investment.

Summary: The semiconductor industry's rapid growth has made significant progress in addressing clean energy concerns, but unresolved issues regarding waste solvents remain. Pyrolysis is a promising approach to tackle these challenges. This study selected waste methyl ethyl ketone (MEK) as the feedstock for pyrolysis, resulting in various residual products. Experimental results demonstrated the yield of fixed carbon, tar, and fuel gases under specific operating conditions. The research included lab-scale experiments and field-scale system studies to develop a comprehensive concept for a thermal cracking plant, incorporating software calculations and a scaled-up pyrolysis process.

Summary: This study investigated the biofiltration of methyl ethyl ketone (MEK) using pressmud and cornstack as packing materials. The performance of the biofilter was evaluated under different operating conditions, and parameters such as removal rates, elimination capacity, temperature, pressure drop, carbon dioxide production, and bed height variation were measured. The results showed that the mixture of 80% cornstack and 20% pressmud achieved a MEK removal efficiency of 97% at an inlet concentration of 0.2 g m(-3) and a gas flow rate of 0.03 m(3) h(-1). The maximum removal efficiency was obtained at an inlet concentration of 1.2 g m(-3) and a gas flow rate of 0.12 m(3) h(-1) for all tested conditions.

Summary: This paper investigated the Lipozyme 435-catalyzed synthesis of xylose oleate in MEK, studying the effects of substrate ratios, temperature, and time on esterification rates. Results showed that an excess of oleic acid was favorable for the reaction, and the highest Lipozyme 435 activities occurred between 55 and 70 degrees C. The study also found that the predicted kinetic model fitted well with experimental data and there was no evidence of inhibitions.

Summary: A clean coupling process was proposed to recover ethyl acetate and water using a reactive distillation column, avoiding over-recycling of raw materials. An extractive distillation scheme using DMSO was introduced to reduce energy requirements for the purification of a mixture of ethanol, water, and ethyl acetate. By optimizing operating conditions and heat integration, the energy intensity was further reduced.
