Comparison of solvent recovery processes in petrochemical industry: membrane condensation shows significant advantages over other processes

In the petrochemical industry, solvent recovery is a crucial link, which is not only related to the economic benefits of enterprises, but also has a profound impact on environmental protection. At present, there are many kinds of solvent recovery processes in the market, among which the membrane condensation recovery process has significant advantages compared with other traditional processes.

Many businesses adoptactivated charcoalEquipment carried outwaste gas treatmentHowever, activated carbon replacement is frequent and costly. Carbon must be changed once a month, and hazardous waste disposal must be added for each carbon change. The waste carbon cannot be discarded at will. Qualified companies must be invited to take it away. The procedures are complicated and the labor cost is high. And activated carbon adsorption is only the organic matter in the exhaust gas transferred to the carbon, the problem is not really solved. In addition,RTOAlthough the equipment has a good effect on waste gas treatment, the operating cost is too high to bear. Especially when treating low-concentration exhaust gases, continuous natural gas supplementation is required, and the value of the natural gas consumed exceeds that of the recovered solvents. If the operating load is reduced, emissions will still fail to meet the standards. At the same time, the solvents in the exhaust gas are either burned off or adsorbed, which not only wastes resources but also increases environmental protection costs.

In contrast, LuoyangWohong PetrochemicalThe membrane condensation recovery unit of Equipment Co., Ltd. shows many advantages. The device employs three-stage condensation plusgas separation membraneCombined process with low operating costs. Only consume electricity, refrigeration compressor and vacuum pump are frequency conversion control, can automatically adjust the power according to the exhaust gas load, effectively control power consumption. The equipment can condense and liquefy the organic solvent in the exhaust gas for recovery, and the recovery purity can reach a high level. The recovered solvent can be directly reused for production or external sales, and the environmental protection expenditure can be converted into economic benefits.

The service life of the core consumable membrane components of the membrane condensation recovery unit of Wohong Petrochemical Company is three to five years. The daily maintenance is mainly to check the pressure and recovery liquid level of the refrigeration system every week, clean the heat exchanger fins every month, and replace the refrigerating oil and drying filter every year. There is no trouble of frequent replacement of consumables. Its skid-mounted integrated design is also very excellent. All components are integrated on a stainless steel base, and assembly and testing are completed before leaving the factory. The site can be used only by connecting the power source and air duct. The installation period is short, the floor area is small, and the explosion-proof configuration is optional. It is suitable for explosion-proof places such as chemical industry and pharmacy.

From the perspective of the scope of application, the equipment has a good recovery effect on common organic solvents such as hydrocarbons, esters, ketones, alcohols, halogenated hydrocarbons, etc., and is suitable for chemical, pharmaceutical, printing, coating, electronics, gas stations, etc. The medium and high concentration exhaust gas treatment scenarios in the industry can also be customized according to customer working conditions.

Relying on the R & D platform of Henan Oil and Gas Recovery Engineering Technology Research Center, Luoyang Wo Hong Petrochemical Equipment Co., Ltd. has set up a professional scientific research, manufacturing and marketing team, and designed a variety of technical solutions and equipment for VOCs waste gas recovery and treatment. The company focuses on working closely with customers, in-depth understanding of customer needs, to provide customized solutions. With profound professional knowledge, rich practical experience and continuous innovation spirit, we continue to promote technology upgrading and product optimization. In the field of petrochemical solvent recovery, the membrane condensation recovery process of Wo Hong Petrochemical deserves the attention and selection of enterprises.
