Luoyang Wohong Petrochemical Equipment Co., Ltd. skid-mounted VOCs organic solvent liquefaction recovery device adopts the delivery mode of factory prefabrication, whole machine debugging and on-site rapid docking, supporting operation guidance and after-sales support, shortening the technical transformation cycle and reducing the impact of shutdown.
2026-09-11What are the on-site inspections for environmental protection at gas stations? One unloading oil recovery, two refueling oil recovery, three treatment devices, tank sealing, online monitoring, hazardous waste disposal, and environmental impact assessment procedures are explained item by item.
2026-10-23The solvent recovery device is prone to freezing blockage, instrument drift and parameter mismatch in winter, and this paper explains the drop point, parameter adjustment method and inspection arrangement of antifreeze matching.
2026-09-20Fine chemicals will continue to produce VOCs organic tail gas in the production links such as distillation, reactor pressure relief, vacuum desolubility, centrifugal discharge, storage tank respiration, etc. The waste gas composition is complex, often containing ethyl acetate, acetone, dichloromethane, n-hexane, alcohols and so on.
2026-09-10In the process of fine chemical production, synthesis reaction, distillation operation, vacuum desolvation, material transfer, storage tank storage and other processes will continue to produce a large amount of volatile exhaust gas, the exhaust gas is rich in ethyl acetate, dichloromethane, acetone, methanol and other high-value organic solvents.
2026-09-07The 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.
2026-09-05During 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.
2026-09-04Fine 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,
2026-09-03Chemical, new materials, polymer synthesis, pharmaceutical production process, will produce halogenated alkanes, ethers, alcohols, olefin monomer VOCs waste gas, common components include dichloromethane, chloroform, methyl ether, ethyl ether, methanol, ethanol, ethylene, butadiene, etc.
