A French chemical company needs to quickly condense and recover organic vapors generated during the production process to improve resource utilization and reduce emissions. We KDP company has decided to adopt a plate condenser, utilizing its high heat transfer efficiency, compact structure, and easy maintenance to achieve process optimization. The main components of the medium are a mixture of ethanol and ethyl acetate. We used 316L 0.6mm stainless steel that is resistant to weak acid corrosion. The sealing gasket is made of EPDM, which can withstand high temperatures up to 120 ℃. The corrugated plate design enhances turbulence, reduces the amount of cooling water used, and saves costs. Reduce comprehensive energy consumption by 30% to meet the carbon neutrality target requirements of enterprises. This case solves the efficiency and maintenance problems of traditional condensing equipment in chemical steam recovery through the innovative application of plate condenser, especially suitable for working conditions of medium and low temperature, medium and low pressure, easy scaling or corrosive media, creating significant economic and environmental benefits for enterprises.
