The laboratory is a place for scientific research and innovation, but the organic waste gas discharged from the fume hood-acetone, dichloromethane, ethyl acetate, ethanol, toluene, etc., is a long-neglected source of pollution. Laboratory exhaust has its particularity. Air volume is small, usually every small
2026-06-11How to deal with dichloromethane waste gas in pharmaceutical factories is a recognized problem in the industry. This solvent has low boiling point and fast volatilization, and belongs to halogenated hydrocarbon VOCs. Traditional treatment methods have their own limitations: activated carbon adsorption saturation fast, frequent carbon exchange, saturated carbon as a hazardous waste.
2026-06-11Gas separation membrane VOCs concentration process Gas separation membrane VOCs concentration process is a membrane separation as the core of the waste gas pretreatment technology. The process uses the difference in the permeation rate of different gas molecules in polymer membrane materials,
2026-06-09Compressed condensed film method VOCs recovery system Compressed condensed film method VOCs recovery system is a kind of waste gas treatment device with physical separation as the core. The system couples the three technical gradients of compression, condensation and membrane separation through each.
2026-06-09Condensation membrane separation skid-mounted complete equipment Condensation membrane separation skid-mounted complete equipment is a modular VOCs exhaust gas treatment device that integrates compression condensation and membrane separation technology. The equipment adopts a skid-mounted design, which combines the compressor, condensing
2026-06-09Pharmaceutical halogenated hydrocarbon membrane condensation recovery pharmaceutical industry in the production of cephalosporins, amoxicillin and other raw materials, halogenated hydrocarbons (mainly dichloromethane) as extraction and crystallization solvents are widely used. These solvents have low boiling point, strong volatility,
2026-06-09Skid-mounted oil and gas recovery membrane separation unit Skid-mounted oil and gas recovery membrane separation unit integrates compression condensation and membrane separation technology, adopts modular design, compressor, condenser, membrane module and control system are all integrated on the steel base, completed before leaving the factory
2026-06-09Compressed condensation membrane separation VOCs recovery technology Compressed condensation membrane separation technology is a physical separation as the core of the VOCs waste gas treatment method. The technology through the compression, condensation and membrane separation of the three units of the gradient combination, real.
2026-06-04The principle of this process is to realize selective separation by using the difference of permeation rate between dichloromethane gas and nitrogen gas in the polymer separation membrane, so as to achieve the purpose of enrichment and recovery of organic solvent. High concentration organic matter is recovered by condensation method,
2026-06-04Chemical storage tank area is the key area of VOCs unorganized emission. When the storage tank is loading and unloading materials and the temperature difference between day and night changes, the breathing valve is frequently opened, and the high concentration organic waste gas is discharged intermittently. This kind of exhaust gas concentration fluctuations, complex components, the treatment.
