Chemical and pharmaceutical high concentration exhaust gas compression condensation membrane separation equipment, fully qualified supplier Luoyang Wohong Petrochemical

In the process of chemical and pharmaceutical production, processes such as distillation, devolatilization, reactor pressure relief, and solvent feeding generate a large amount of high concentration VOCs organic exhaust gas, which contains high-value solvents such as alcohols, ketones, esters, and halogenated hydrocarbons. High concentration exhaust gas has a high partial pressure of organic matter, and the medium is flammable and explosive. Some components are corrosive, and the production conditions fluctuate intermittently, often carrying material droplets and water vapor. Traditional incinerationactivated charcoalThe adsorption process has prominent drawbacks when used in high concentration exhaust gas scenarios. Burning will consume a large amount of solvent resources, and activated carbon adsorption load exceeding the limit is prone to failure. Compression condensation membrane separation equipment has become the preferred equipment for the resource recovery of high concentration exhaust gas.

There are obvious shortcomings in adapting traditional treatment processes to high concentration exhaust gases. The incineration process directly destroys organic solvents, resulting in significant resource losses. The combustion of halogenated media also generates corrosive flue gas, requiring high investment in the supporting post-treatment system. Activated carbon adsorption faces high concentration exhaust gas, the adsorption material quickly reaches saturation, consumables are frequently replaced, hazardous waste output is large, and operating costs remain high. The pure cryogenic condensation process can recover some solvents from high concentration exhaust gas, but the energy consumption is high and the residual exhaust gas is still difficult to meet the standard. Compression condensation membrane coupling belongs to a pure physical recovery process, without combustion or chemical reactions. The high concentration exhaust gas is first subjected to filtration and foam removal pretreatment to remove impurities from the droplets; By using an explosion-proof compressor to increase the partial pressure of organic vapor, most organic solvents are directly liquefied and collected through multi-stage gradient condensation; The uncondensed residual gas enters the organic membrane unit for selective enrichment, and the high concentration permeate gas is circulated and recovered at the inlet of the reflux compressor. After treatment, the tail gas meets the emission standards, and the recovered solvent can be reused in production after passing the testing, balancing the recovery benefits and environmental compliance.

There are several key points for equipment selection under high concentration exhaust conditions. High concentration media are more prone to corrosion and leakage risks, and overcurrent components, valves, and seals should be made of corrosion-resistant materials such as 316L stainless steel. The explosion-proof level of the whole machine shall not be lower than ExdIIBT4, and it shall be equipped with a complete set of safety protection devices such as overpressure protection, overtemperature interlock, and combustible gas leakage alarm to ensure production safety under high concentration conditions. The front-end filtration and foam removal pretreatment unit cannot be omitted, as droplets and impurities can cause blockage and damage to the heat exchanger and membrane components. The self-control system is suitable for intermittent production, supports variable frequency regulation, and can cope with the impact load of exhaust concentration and air volume. In the early stage of the project, it is necessary to provide measured parameters such as exhaust gas volume, composition, concentration range, and water content, and carry out customized process accounting. Standard models cannot be directly applied.
