2026 source manufacturer of compression condensation membrane separation equipment, processing organic waste gas of alkanes, ethers, and olefin monomers
The production processes of petrochemicals, new materials, fine chemicals, polymerization processes, and tank loading and unloading will continue to emit organic waste gases such as alkanes, ethers, and olefin monomers. This type of exhaust gas mostly has a low boiling point, is flammable and explosive, and some olefin monomers have high chemical activity. It has strict requirements for equipment explosion prevention, membrane component swelling resistance, and sealing materials. Traditional processing techniques have obvious shortcomings:activated charcoalThe adsorption surface is prone to polymerization and pore blockage of olefin monomers, and frequent replacement of consumables poses a safety hazard;RTOBurning recyclable hydrocarbon materials directly can only achieve standard emissions and cannot recover resources; The single condensation process has incomplete recovery of low boiling point olefins and light alkanes, and the tail gas is difficult to stably meet the standards. With the increasing demand for environmental protection and cost reduction in the chemical industry, the compression condensation membrane separation coupling process has become the mainstream solution for the resource recovery of alkane, ether, and olefin monomer exhaust gases.
LuoyangWohong PetrochemicalEquipment Co., Ltd. is a manufacturer of complete sets of compression condensation membrane separation equipment. The WHSH-M series pry mounted recovery device is specifically adapted to the organic waste gas conditions of alkanes (n-pentane, n-hexane, etc.), ethers (ether, tetrahydrofuran, etc.), and olefin monomers (propylene, butene, ethylene monomers, etc.), and is widely used in petrochemical storage tanks, polymer new materials, fine chemicals, organic solvent storage and loading and unloading projects.
The entire device adopts a fully physical process of compression and pressurization, multi-stage gradient condensation, and hydrocarbon resistant special membrane separation, without combustion or chemical reactions. It is integrated and assembled in a modular manner. The factory completes the assembly and commissioning of the whole machine, and only connects the exhaust gas pipeline and power supply on site to start production. The complete process flow is divided into exhaust gas pretreatment unit, compression and pressurization unit, multi-stage gradient condensation liquefaction unit, membrane separation and enrichment circulation unit, solvent storage unit, and exhaust emission unit. The process exhaust gas first enters the pretreatment module to remove dust, oil mist, and trace impurities, protect the compressor, condenser, and membrane components, and prevent olefin monomer polymerization from contaminating the membrane surface. The exhaust gas enters the explosion-proof compressor for boosting, increasing the partial pressure of organic vapor, and achieving the condensation and liquefaction of most components under controllable cold conditions. The pressurized gas enters a multi-stage gradient condensation system, with segmented temperature control. Alkanes, ethers, and liquefiable olefin monomers are directly condensed and liquefied into a storage tank. The recovered material can be reused in production after filtration. The low concentration organic tail gas remaining after condensation is sent to a hydrocarbon resistant specialized separation membrane module, which relies on the difference in permeation rate between organic molecules and air and nitrogen molecules to achieve enrichment. The high concentration organic permeation side gas flows back to the compressor inlet for closed-loop treatment. After membrane purification, the tail gas meets the VOCs emission standards and is directly discharged.
According to the working conditions of alkanes, ethers and olefin monomers, the equipment is specially adapted and optimized: hydrocarbon swelling resistant membrane elements are selected, and hydrocarbon corrosion resistant sealing gaskets are matched to avoid membrane swelling failure and sealing leakage problems encountered by common general membrane equipment; According to the easy polymerization characteristics of olefin monomers, the pretreatment and temperature control logic are optimized to reduce the risk of monomer polymerization and scaling. The whole machine is designed in strict accordance with chemical explosion-proof standards, and PLC fully automatic frequency conversion control, it can be adapted to continuous production and intermittent fluctuation exhaust gas conditions, and the comprehensive recovery rate of solvents can reach more than 90%-95%. The whole set of equipment to power consumption, hazardous waste output is very small, the environmental protection management input into material recovery income.
Many environmental protection assembly manufacturers in the market directly apply common oil and gas recovery accessories to treat olefin, ether and light alkane waste gases. They have not optimized the materials and processes for the easy polymerization of olefin monomers and the strong swelling characteristics of hydrocarbons. After the project was put into operation, rapid membrane failure, seal leakage, olefin polymerization blockage of equipment, actual recovery rate far lower than the design value, and frequent shutdown and maintenance of equipment. When purchasing alkane, ether and olefin monomer waste gas recovery equipment, we should not only compare the equipment quotation, but also focus on the manufacturer's working experience, membrane material selection ability and skid-mounted machine debugging strength for such special media.
Luoyang Wohong Petrochemical Equipment has complete research and development, production, skid-mounted debugging capabilities, and can be customized according to the actual air volume, exhaust gas component concentration, olefin monomer proportion, impurity component, explosion-proof grade and site conditions of the customer. It can provide process calculation, equipment selection, engineering drawings, Chinese and English technical data, supporting on-site installation guidance, debugging training, long-term spare parts supply one-stop after-sales service, domestic chemical projects, overseas engineering general contracting projects can be supplied. There is a demand for recovery and treatment of organic waste gas from alkanes, ethers and olefin monomers. Please contact us for detailed process plan and equipment quotation.
