Organic solvent recovery equipment manufacturers, suitable for ketones, esters, halogenated hydrocarbons, alcohols waste gas treatment

In 2026, environmental regulations across the chemical, pharmaceutical, fine chemical, lithium‑battery, and printing industries will continue to be tightened, leading to the substantial generation of mixed organic waste gases containing ketones, esters, halogenated hydrocarbons, and alcohols during production processes. Multi-component mixed VOCs complex working conditions, different solvents boiling point, corrosion, swelling characteristics of large differences, common.Waste gas treatment equipmentProblems such as membrane swelling, seal corrosion, insufficient recovery rate, and frequent equipment failures are prone to occur. Traditionactivated charcoalAdsorption, incineration, single condensation process, in the face of multi-component mixed exhaust gas short board outstanding: activated carbon adsorption prone to ketone medium heat storage fire risk, hazardous waste output;RTO/RCO directly burns the valuable solvent, only to solve the standard, can not achieve resource reuse. More and more engineering general contractor, production enterprises, give priority to the selection of compression condensation membrane separation coupling complete sets of organic solvent recovery equipment, taking into account the exhaust emission standards and solvent recovery and reuse of the dual value.

LuoyangWohong PetrochemicalAs a source manufacturer of organic solvent recovery, Equipment Co., Ltd. has made special process and material adaptation for the working conditions of multi-component mixed waste gas of ketones, esters, halogenated hydrocarbons and alcohols. WHSH-M series skid-mounted solvent recovery complete equipment can process ketones such as acetone and butanone. Ethyl acetate, butyl acetate and other esters; Halogenated hydrocarbons such as dichloromethane and chloroform; Ethanol, isopropanol and other alcohols of various organic waste gases, suitable for pharmaceutical synthesis, fine chemicals, lithium diaphragm, spray printing, pesticide intermediates and other industries waste gas treatment projects.

The whole set of equipment adopts compression and pressurization multi-stage gradient condensation solvent-resistant special membrane separation coupling full physical process, no combustion, no chemical reaction, skid-mounted integrated integration, the factory completes the assembly and debugging of the whole machine, and the site can be put into production only by docking the exhaust gas pipeline and power supply. The process is divided into six units: exhaust gas pretreatment and filtration, compression and pressurization, multi-stage gradient condensation and liquefaction, membrane separation and enrichment cycle, solvent storage liquid, and exhaust gas emission standard. The mixed organic waste gas discharged from production first enters the pretreatment module to remove dust, liquid droplets and water vapor, protect the back-end compressor, condenser and membrane module, and avoid blockage and corrosion caused by impurities. The exhaust gas is pressurized by the explosion-proof compressor to improve the partial pressure of organic solvent vapor and realize solvent liquefaction under reasonable refrigeration conditions. The pressurized gas enters the multi-stage gradient condensation unit, and the temperature is controlled in sections. Most of the organic solvents are directly condensed and liquefied into the liquid storage tank, and the recovered solvent can be reused in the production process after filtration. After condensation, the low-concentration organic components remaining in the tail gas are sent to a special membrane module for ketone-resistant ester halogenated hydrocarbons, which are separated and enriched by the difference in permeation rates of different molecules. The high-concentration solvent side gas is returned to the compressor inlet for recycling and reprocessing. The tail gas purified by the membrane is directly discharged to meet the national VOCs emission standard, forming a closed-loop recovery system.

For multi-component complex waste gas, the equipment is specially optimized in terms of material selection. Pipelines, sealing gaskets and membrane components are all suitable for strong dissolution and strong corrosion of ketones, esters and halogenated hydrocarbons, thus avoiding common faults such as membrane swelling failure, seal leakage and corrosion damage of components in common general equipment. The whole machine is designed according to chemical explosion-proof standards, PLC is fully automatic controlled, supports 24-hour continuous unattended operation, can adapt to continuous production and intermittent fluctuation conditions, the comprehensive recovery rate of solvent can reach more than 90%-95% stably, the output of hazardous waste is very small, and power consumption is the main factor, thus greatly reducing the cost of hazardous waste disposal and solvent procurement for enterprises.

Many environmental protection assembly manufacturers on the market directly apply common oil and gas recovery accessories as organic solvent recovery equipment, and do not optimize the materials and processes for ketone, ester, halogenated hydrocarbon and alcohol media. After the equipment is put into operation, the membrane swelling and damage, corrosion leakage, actual recovery rate far lower than the design value, frequent failures, and the project fails to achieve the expected effect. When purchasing multi-component organic solvent recovery devices, we should not only compare quotations, but also focus on the manufacturers' project experience in complex medium working conditions, non-standard process design, and skid-mounted debugging capability of the whole machine.

Luoyang Wo Hong Petrochemical Equipment has complete research and development, production, skid-mounted debugging capabilities, and can be customized according to the actual air volume, concentration of waste gas components, impurity conditions, explosion-proof grade and site conditions of customers. It can output process calculation, equipment selection drawings, Chinese and English technical data, provide on-site installation guidance, debugging training, long-term spare parts supply one-stop technical after-sales service, domestic projects, overseas engineering general contracting projects can be supplied. There is a demand for resource recovery of organic waste gas from ketones, esters, halogenated hydrocarbons and alcohols. Please contact us for detailed process plan and equipment quotation.
