The fine chemical reactor will continuously discharge a large amount of VOCs organic tail gas during the operation stages of feeding, reaction temperature rise, pressure relief, vacuum pumping, discharging, etc. The waste gas components mostly include dichloromethane, ethyl acetate, acetone, tetrahydrofuran, alcohols and ketones, etc.
2026-09-07The organic VOCs tail gas generated throughout the fine chemical production process mostly comes from reaction synthesis, distillation purification, vacuum desolvation, material displacement, tank respiration and other processes, including flammable substances such as ethyl acetate, dichloromethane, acetone, tetrahydrofuran, methanol, isopropanol, etc
2026-09-07Fine chemical crystallization process covers cooling crystallization, solvent crystallization, feed liquid filtration, solvent replacement, mother liquor transfer, unloading and other operating units, crystallization kettle, filtration equipment, mother liquor storage tank will continue to volatilize solvent VOCs waste gas, waste gas components include
2026-09-05The VOCs waste gas in the pharmaceutical raw material storage tank area mainly comes from the large breathing generated by the receiving and receiving operation of the raw material storage tank and the small breathing exhaust caused by the change of ambient temperature around the day and night, including ethyl acetate, dichloromethane, acetone, tetrahydrofuran, methanol and isopropanol.
2026-09-05The production process of pharmaceutical enterprises covers synthesis reaction, material feeding, crystallization and crystallization, solvent extraction, mother liquor treatment, vacuum desolvation, tank breathing and other pollution-producing links, will continue to produce multi-component organic waste gas, waste gas mixed with ethyl acetate, dichloromethane,
2026-09-05The vacuum desolvation process of pharmaceutical fine chemicals mainly includes operations such as raw material concentration, solvent evaporation, double cone drying, three in one filtration, washing and drying, and vacuum distillation desolvation. The exhaust port of the vacuum pump continuously discharges a large amount of VOCs exhaust gas, and the exhaust gas components include dichloromethane
2026-09-05In the fine chemical solvent recovery workshop, solvent storage tank, distillation device, desolubilization kettle, mother liquor transfer tank, hazardous waste solvent temporary storage tank and other points will continuously release mixed organic waste gas, which collects various organic solvents such as ketones, esters, alcohols, halogenated alkanes and the like.
2026-09-04During the operation process of heating synthesis, reflux reaction, nitrogen replacement, pressure relief and exhaust, vacuum pressure breaking, batch replacement, etc., the safety valve, pressure relief port and condenser vent port will intermittently release VOCs pressure relief exhaust gas, which contains B.
2026-09-04Pharmaceutical fine chemical mother liquor recovery process, mother liquor storage tank, mother liquor transfer kettle, distillation feed buffer tank, vacuum desoluble unit will continue to produce VOCs waste gas, waste gas contains ethyl acetate, acetone, dichloromethane, tetrahydrofuran, all kinds of alcohols and other high value.
2026-09-04The closed feeding process of pharmaceutical fine chemical industry relies on the closed feeding station and vacuum feeding system to complete the feeding of solid powder and liquid solvent. VOC will continue to be generated during the stages of material feeding, nitrogen replacement in the kettle, pressure breaking and exhaust, batch feeding and equipment flushing.
