A New Process for Peracetic Acid Production from Acetic Acid and Hydrogen Peroxide Based on Kinetic Modeling and Distillation Simulation

Abstract

The reaction kinetics of peracetic acid from acetic acid and hydrogen peroxide in a helical capillary microreactor was investigated and modeled via regression of the measured conversion rate of hydrogen peroxide. It was found that the activity of the proton in the sulfuric acid solution played a significant role in the synthesis as a catalyst. The activities of the proton were calculated with the ELECNRTL equation and used to obtain a kinetic model with apparent activation energies of peracetic acid synthesis and hydrolysis of 53.63 and 54.45 kJ/mol, respectively. A new continuous process for industrial manufacture of peracetic acid solution (30 wt %) was proposed, where the reacted solution from the microreactor is distilled to separate unreacted reactants and sulfuric acid, which are recycled as a feed. The feasibility of the new process was validated by Aspen Plus simulation and economic assessment.

“…Після завершення процесу реакційну суміш легко розділити. Широкому застосуванню ПК у багатьох процесах заважає їхня низька стабільність, оскільки як у чистому вигляді, так і у розчинах ПК здатні інтенсивно розкладатися навіть за кімнатних температур [6][7][8]. У багатьох промислових процесах застосовують пероксиоцтову кислоту, яка за високих концентрацій здатна розкладатися з вибухом.…”

Machining studies on Monel K − 500 using TiAlN coated tungsten carbide inserts under Ag nanoparticles incorporated modified pongamia pinnata oil lubrication

“…For chemical treatment of pongamia pinnata oil, peracetic acid was indigenously prepared. Peracetic acid was made by combining acetic acid, hydrogen peroxide and sulphuric acid [56]. 74.24 ml of peracetic acid was mixed with 21.44 ml of pongamia pinnata oil and the solution was maintained at 20 °C for 6 h. After 6 h, the processed oil was poured in water and allowed to settle for 1 h. Epoxy oil was allowed to float collect in the top.…”
