Pharmaceutical and chemical skid-mounted recovery equipment, condensing membrane separation process, the manufacturer recommends Luoyang Wo Hong petrochemical equipment, which is suitable for various production conditions in the workshop.

The pharmaceutical and chemical workshop will continue to discharge organic tail gas containing ethyl acetate, acetone, dichloromethane, alcohol ketones and other components in the processes of pressure relief in the reactor, vacuum dissolution, rectification of non-condensable gas, crystallization centrifugation, material transfer, storage tank respiration and so on. The pharmaceutical industry is mostly intermittent batch production, with obvious fluctuations in exhaust air volume and concentration, solvent droplets and water vapor entrained in the air flow, and some media have corrosion characteristics. The workshop belongs to Class A explosion-proof area. The traditional incineration process directly destroys valuable solvents, which consumes high energy and easily produces toxic by-products from the combustion of halogen-containing solvents;activated charcoalAdsorption is easily affected by water vapor, adsorption materials quickly fail, resulting in a large amount of dangerous solid waste; single condensation process is limited by steam partial pressure, low concentration tail gas recovery is not sufficient, it is difficult to balance resource recovery and stable compliance.

Pharmaceutical and chemical skid-mounted recovery equipment adopts condensation and membrane separation coupling full physical process, no open flame, no chemical reaction, no secondary pollutants. The whole set of equipment is integrated on the skid-mounted base. The pipeline assembly, pressure test and linkage debugging of the whole machine are completed in the factory and transported to the project site. It can be put into operation only by docking the exhaust gas collection pipeline, water and electricity and other public works, thus greatly shortening the construction period, occupying a compact floor area and not affecting the long-term shutdown of the original production line.

The VOCs waste gas at each stain production point is collected by a closed negative pressure pipeline and enters the pretreatment unit to remove liquid droplets, aerosol impurities and free moisture entrained by the airflow, protect the back-end condenser and membrane module, and prevent blockage, pollution and corrosion. The pretreated organic waste gas enters the compression unit to increase the partial pressure of organic steam, and is sent to the multi-stage gradient condensation module. Most of the organic solvent steam is liquefied and separated under low temperature conditions. The collected liquid solvent is purified by water separation and precision filtration. The quality meets the production reuse standard and can be returned to the workshop production line for recycling. The low-concentration tail gas remaining after condensation enters the polymer membrane separation unit, and the VOCs component is enriched by the selective permeation of the membrane material to organic molecules, and the purified tail gas meets the environmental emission requirements; the high-concentration organic mixture enriched by the membrane is returned to the front-end compression section for recycling treatment, further improving the overall recovery rate of the solvent.

The contact parts of equipment and medium are made of suitable anti-corrosion materials according to the exhaust gas components. The whole machine is designed and manufactured according to Class A explosion-proof standard. The motor, sensor and valve instrument are all made of explosion-proof type. The system is equipped with over-temperature, over-pressure, combustible gas concentration interlocking protection and emergency venting bypass to effectively avoid potential safety hazards caused by flammable and explosive media. Supporting PLC full-automatic frequency conversion control system, real-time monitoring of temperature, pressure, intake air concentration, automatic adjustment of equipment operating load, flexible adaptation to continuous production, intermittent pressure relief, multi-solvent switching and other workshop production conditions, support long-term unattended stable operation.

LuoyangWohong PetrochemicalAs a manufacturer, the equipment can be customized according to the project exhaust gas air volume, solvent composition, intake temperature, explosion-proof partition of the workshop and site restrictions, and provide a full set of services such as site condition survey, material balance calculation, skid-mounted equipment manufacturing, factory inspection, site installation guidance, operator training and operation and maintenance spare parts supply. The skid-mounted recovery equipment is suitable for API, pharmaceutical intermediates, CDMO and other pharmaceutical and chemical projects, in the recovery of organic solvents to reduce the cost of raw materials at the same time, stable to meet the requirements of VOCs environmental protection, reduce the output of hazardous waste.
