Scrubber

In our scrubber system, EO waste gas by gas capture system will send into a gas-liquid separator and water separation, gas atomization absorption into atomization system, then the gas through the atomization system into the core of the chemical absorption system. Gas is dissolved in the liquid first in the absorption tower and then provides hydrogen ions in a sulfuric acid catalytic hydration reaction. Reaction products are mainly C2H6O2 and very little C4H10O3, C6H14O4, multivariate and trace of polyester glycol. The product of the liquid entrainment is entered into the collecting tank and the liquid is recycled for use when the liquid is unsaturated. After treatment, the gas was discharged from the top of the tower, and the tower was collected at the next level, with several washing towers, and a small amount of unabsorbed reaction was discharged by the exhaust cylinder.
The gas treatment principle of ethylene oxide is the hydrolysis reaction of ethylene oxide, Ethylene glycol is produced by hydrolysis of ethylene oxide in dilute sulfuric acid (50% sulfuric acid, diluted in waste gas treatment system).

FIRSTEO Machinery
Equipment Co., Ltd.

FIRSTEO Machinery Equipment Co., Ltd. is one of the well-known China Scrubber manufacturers and Scrubber suppliers in China. We have our own technology development, design, production, sales and service department. Our products include the overall facilities of the ethylene oxide sterilization workshop, the pretreatment room, the ethylene oxide sterilizer, the analytical room and the ethylene oxide waste gas treat equipment. Our company has established in a quality management system which accordance with ISO9001:2008 and ENISO134585:2003/AC2009. Our company is engaged in: pretreatment - sterilizer - strong analytical --EO waste gas treatment, the whole process equipment manufacturing factory to provide custom Scrubber and wholesale Scrubber . We are a famous China Scrubber suppliers and Scrubber factory of ethylene oxide sterilization that uses hot air heating system in China, and had applied the "utility model patent certificate" (energy saving, water-saving, no corrosion, fast heating speed; which can extend the life of the equipment for 10-15 years). Our own FSTEO-WQ series of ethylene oxide waste air absorption and treatment equipment was developed with the domestic universities. It allows the low temperature reaction process and reselected the catalyst reacting under low temperature. The removal rate of the waste gas was more than 99.9% after the purification of the waste gas. The emission residual gas is far below the national standard requirements. We have also developed an automatic control system which can join the operation between the waste gas treat process and the sterilizing cabinet. Our technical engineers have decades of experience in the industry. So we can provide professional man to install, test, training or repair machine for customer. We have a large number of high-quality customers: Jiangsu Fresenius Medical Care (Germany), Nanchang Kelinnike Medical Appliance (Germany), Shenzhen DooJung Group (Korea), Nanjing micro-tech, Winner Medical and other well-known Pharmaceutical equipment or other related products enterprises in China. We can also provide you with the best equipment and services.
