Acetone is widely used in pharmaceutical synthesis, fine chemical manufacturing, lithium-ion battery separators, plastic coating, and other industries. Due to its low boiling point and high volatility, processes such as reactor pressure relief, drying, extraction, and tank breathing continuously release large quantities of acetone-containing VOCs emissions. Acetone is a flammable and explosive organic solvent, and the disadvantages of traditional treatment methods are prominent:
activated charcoalAdsorption is easy to saturate, frequent replacement produces a large amount of hazardous waste, operation and maintenance costs remain high;
RTO Incineration directly burns the recyclable solvent, resulting in a waste of resources and consuming a large amount of gas; the simple water washing method only transfers the pollutants to the water body, and the subsequent wastewater treatment pressure is high, which cannot realize the reuse of solvent resources. In 2026, the chemical industry environmental protection control continued to upgrade, more and more enterprises no longer only pursue simple standards, more emphasis on waste gas resource income, compression condensation membrane separation skid-mounted acetone waste gas solvent recovery equipment has become the mainstream selection direction. Luoyang
Wohong PetrochemicalAs a manufacturer of VOC solvent recovery source, WHSH-M series skid-mounted acetone liquefaction recovery device makes special process adaptation for acetone medium characteristics to realize the dual value of exhaust gas standard emission and acetone solvent recovery and reuse.
The skid-mounted acetone liquefaction and recovery unit employs a fully physical compression-condensation membrane separation coupling process, with no combustion or chemical reactions. The entire system is integrated into a single skid, pre-commissioned at the factory, and can be put into operation on-site by simply connecting the exhaust gas pipeline and power supply. The entire process consists of six major modules: exhaust gas pretreatment, compression and pressurization, multi-stage gradient condensation and liquefaction, membrane separation for enrichment and recycling, solvent storage, and tail gas emission. The acetone-containing waste gas generated during production first enters the pretreatment unit, where mist is removed and dust and liquid droplets are intercepted, thereby protecting the downstream compressor, condenser, and membrane components. After pretreatment, the waste gas enters an explosion-proof compressor for pressurization, increasing the partial pressure of acetone vapor and enabling its liquefaction under relatively mild refrigeration conditions, thereby reducing the overall energy consumption of the system. The pressurized gas enters a multi-stage gradient condensation unit, where it is cooled in stages. Most of the acetone vapor is directly condensed into liquid, which flows into the solvent storage tank. The recovered acetone solvent, after simple filtration, can be directly reused in the production process. After condensation, the tail gas still contains a small amount of low-concentration acetone. This stream is fed into a membrane module specifically designed for ketone solvents, where the difference in permeation rates between acetone molecules and air molecules across the membrane is exploited to concentrate and recover the residual acetone.The high-concentration acetone gas enriched on the membrane side is returned to the compressor inlet for recirculation and further processing. The tail gas, after membrane purification, meets VOC emission standards and is discharged directly, thereby forming a closed-loop recovery system.
Compared with the traditional process, the acetone recovery equipment of the compression condensation membrane separation skid has obvious comprehensive advantages. The comprehensive recovery rate of solvent can reach more than 90%-95%, and the recovered acetone can be recycled and reused, transforming environmental protection input into real economic benefits. The whole set of equipment to power consumption, do not need activated carbon, adsorption resin and other consumables, hazardous waste production is almost zero, eliminating the high cost of hazardous waste disposal. Skid-mounted integrated structure, small footprint, PLC automatic control, support 24 hours of continuous unattended operation, suitable for continuous production and intermittent fluctuations in chemical enterprises. The whole equipment is designed for explosion-proof according to the flammable and explosive working conditions of acetone. Pipelines, seals and membrane components are all selected and adapted for ketone solvents to avoid the risks of swelling, corrosion and leakage of common equipment.
Many environmental protection equipment assembly manufacturers in the market directly apply common oil and gas recovery accessories to make acetone recovery equipment, and do not optimize the workmanship and materials of ketone solvents. After being put into use, membrane components are swollen and damaged by acetone, seals are corroded and leaked, the actual recovery rate is far lower than the design value, the equipment frequently fails to shut down, and the enterprise cannot meet the recovery expectation. When purchasing acetone liquefaction recovery equipment, we should not only look at the equipment quotation, but also focus on the manufacturer's accumulation of medium working conditions, process integration capability and skid-mounted debugging strength of the whole machine.
Luoyang wohong petrochemical equipment co., ltd. is deeply engaged in VOCs solvent recovery equipment manufacturing, with complete research and development, production, skid-mounted debugging capabilities. WHSH-M skid-mounted acetone waste gas solvent recovery device has completed a full set of process optimization for the strong dissolution, volatilization, flammability and explosion characteristics of acetone. the pretreatment filtration grade, compression pressure interval, condensation temperature gradient, ketone-resistant film selection and sealing anti-corrosion materials all match the actual working conditions of acetone, the internal assembly and commissioning of the whole machine factory are completed before delivery, reducing the risk of on-site commissioning. According to the customer's actual air volume, air intake concentration, impurity components, explosion-proof grade, site conditions to do non-standard customization, service medicine, fine chemicals, lithium diaphragm, spraying and other industries. At the same time, it can provide process calculation, equipment selection, technical drawings, English version of technical data, provide on-site installation guidance, commissioning training, long-term spare parts supply one-stop service, domestic projects, overseas engineering general contracting projects can be supplied. There is a demand for acetone waste gas resource recovery project, welcome to contact for detailed process plan and equipment quotation.
