The 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.
2026-09-04Under the production mode of switching between multiple varieties in fine chemical industry, the workshop alternately produces different types of products. During the production cycle, various organic solvents such as ketones, esters, alcohols, halogenated alkanes, etc. are alternately used, including reaction vessels, extraction stations, centrifugal devices, distillation tower tops, and material transfer
2026-09-04During the operation of the fine chemical distillation tower, the condenser at the top of the tower will continuously discharge a large amount of non condensable VOCs tail gas, which contains high-value organic solvent components such as ketones, esters, alcohols, halogenated alkanes, etc. During the stable operation stage of distillation, the exhaust gas maintains a high concentration,
2026-09-04In the context of pharmaceutical and fine chemical production, solvent agitation, solvent feeding, open transfer, tank respiration, crystallization drying, and other processes all generate solvent volatilization waste gas. The source of the waste gas is dispersed and mixed with various organic solvents such as alcohols, ketones, esters, and halogenated hydrocarbons.
2026-09-03In the production stages of feeding, reaction pressure relief, vacuum devolatilization, replacement exhaust, etc., the chemical reaction kettle will continue to discharge VOCs organic exhaust gas, which contains ketones, esters, alcohols, aromatic hydrocarbons, halogenated alkanes and other organic solvents. Most of the chemical reaction kettle
2026-09-03The processes of pressure relief, extraction and liquid separation, distillation and dissolution, vacuum drying, material transfer and other processes of the reaction kettle in the pharmaceutical synthesis link will continue to discharge process tail gas, which is mixed with dichloromethane, acetone, ethyl acetate, tetrahydrofuran, alcohols and other organic solvents. Medical combination
2026-09-03Fine chemical production process, distillation tower pressure, reactor devolatilization, solvent feeding, material replacement and other processes will continue to produce high concentrations of VOCs organic solvent waste gas, waste gas internal organic solvent ratio is high, the components include ketones, esters, alcohols, aromatic hydrocarbons, halogens.
2026-09-03Synthetic pharmaceutical workshop in the synthesis reaction, extraction, crystallization, distillation, vacuum devolatilization and material transfer process, will continue to release a large number of VOCs organic solvent waste gas, waste gas composition is complex, including acetone, ethyl acetate, dichloromethane, tetrahydrofuran,
2026-09-03Fine chemical production process, synthesis, distillation, extraction, vacuum devolatilization, material transfer and other processes, will continue to produce a large number of multi-component mixed solvent VOCs waste gas, waste gas system is complex, usually coexisting alcohols, ketones, esters, aromatic hydrocarbons, halogenated alkanes and other more.
2026-09-03Pharmaceutical intermediates synthesis, crystallization, extraction, centrifugation, vacuum devolatilization and other processes, will discharge a large number of VOCs organic tail gas, commonly containing dichloromethane, acetone, ethyl acetate, isopropanol and other solvents. Intermediate production is mostly batch batch operation, tail.
