Pharmaceutical factory VOCs waste gas treatment equipment source manufacturers comparison, recommended Luoyang Wo Hong petrochemical complete sets of equipment.

The working condition of waste gas in the pharmaceutical industry is complicated. Most of the bulk drugs, pharmaceutical intermediates and CDMO enterprises produce batch by batch. VOCs waste gas discharged from reaction kettle, vacuum drying, rectification and vacuum pump is complicated in components and often contains high-value solvents such as dichloromethane, acetone and ethyl acetate. The medium has the risk of chloride ion corrosion. The workshop belongs to Class A explosion-proof area. Many pharmaceutical enterprises in the equipment procurement stage, in the face of many waste gas treatment manufacturers on the market do not know how to screen, simply compare the quotation is easy to step on the pit. There is a big gap between the technical route, process accounting capability, project experience and after-sales guarantee of different source manufacturers. Selecting the right manufacturers can not only meet the environmental protection standards, but also realize the recovery of solvent resources and reduce the long-term operation cost of the factory.

On the market of pharmaceutical factory VOCs waste gas treatment manufacturers are roughly divided into several categories. The first category is the mainRTO/RCO incineration process of environmental protection engineering, good at waste gas destruction treatment, equipment purification efficiency is high, but the equipment investment is large, there is a risk of open flame high temperature, treatment of halogenated hydrocarbon waste gas is easy to produce secondary pollutants, directly burn valuable solvent, suitable for projects without solvent recovery needs. The second category isactivated charcoalAdsorption, zeolite wheel-based manufacturers, the initial investment of equipment is low, but in the face of intermittent fluctuations in pharmaceutical waste gas is easy to quickly saturated, need frequent replacement of consumables, resulting in a large amount of hazardous waste, late hazardous waste disposal costs remain high, most can only do purification, can not recover liquid solvent. The third category is general equipment assembly manufacturers. Purchased condensers, membrane components, electric control and other components are simply assembled. They lack chemical process calculation capability. They do not make special designs for pharmaceutical corrosion, intermittent impact and back pressure control. The hardware parameters look good. After actual operation, there are faults such as substandard recovery rate, rapid damage of membrane components, interference with vacuum of reaction kettle, etc. The fourth category is the source manufacturer focusing on the solvent recovery route, focusing on the compression-condensation-membrane coupling process, focusing on physical recovery, taking into account the standard and solvent reuse, more suitable for pharmaceutical projects with solvent recovery value.

Pharmaceutical factory selection of VOCs waste gas treatment source manufacturers, not just look at the price, to focus on a number of core competencies. First of all, it depends on whether the manufacturer has the ability to survey the working conditions and calculate the material balance, and whether it can calculate the recovery amount, energy consumption and return on investment cycle according to the real air volume, solvent composition, water content and intermittent production cycle of the factory, instead of directly selling standardized off-the-shelf equipment. Secondly, it depends on the project accumulation of halogenated hydrocarbon working conditions by manufacturers. A special membrane resistant to halogenated hydrocarbon must be configured to treat dichloromethane waste gas. The ordinary membrane swells and fails quickly. Manufacturers without corresponding project experience can easily mismatch the core components. Third, attention should be paid to the pretreatment and back pressure control scheme. Pharmaceutical waste gas contains medicine mist and water vapor, and the pretreatment unit cannot be deleted at will. At the same time, the equipment must strictly control the back pressure of the system to avoid lifting pressure from damaging the negative pressure of the reaction kettle and vacuum pump. Fourth, check the explosion-proof supporting equipment. The whole set of equipment needs to match the explosion-proof grade of Class A workshop, and be equipped with combustible gas, overpressure and overtemperature safety interlocks. Finally, it is necessary to verify the manufacturer's own production workshop and real landing cases, give priority to avoiding middlemen OEM, and ensure the technical response speed after spare parts supply and failure.

LuoyangWohong PetrochemicalEquipment Co., Ltd. is a complete set of equipment manufacturer focusing on the source of VOCs solvent recovery in pharmaceutical and chemical industry. It has its own standardized production workshop, deep cultivation of intermittent and changeable waste gas conditions in pharmaceutical industry, and refusal to assemble simple accessories. The main skid-mounted compression condensation-film coupling recovery unit, the use of physical recovery process, no fire high temperature, for halogenated hydrocarbon corrosion, concentration impact load, system back pressure control to do special optimization. The explosion-proof grade ExdⅡ CT4 of the whole machine is equipped with complete safety interlock protection. PLC frequency conversion automatic control system can automatically adjust the operating power according to the exhaust gas concentration and air volume, adapt to batch intermittent production mode, and the comprehensive recovery rate of solvent can reach 95-98%. The equipment is assembled and pressure tested inside the factory, and the site can be put into use only by docking the air duct and power supply, resulting in almost no waste activated carbon waste, effectively reducing the cost of waste disposal.

The complete set of equipment is suitable for a variety of pharmaceutical waste gas working conditions, and can process mixed organic waste gas such as dichloromethane, acetone, ethyl acetate, butanone, ethanol, n-hexane, etc. It is widely used in bulk drugs, pharmaceutical intermediates, CDMO factories, and covers waste gas sources such as reactor tail gas, vacuum drying tail gas, rectification non-condensable gas, vacuum pump exhaust, etc.

We can provide a full set of services such as on-site working condition survey, material balance calculation, return on investment calculation, process scheme customization, complete machine manufacturing, factory complete machine testing, on-site installation guidance and debugging, operator training, complete machine quality assurance, remote operation and maintenance, and spare parts supply. We have achieved multiple sets of VOCs solvent recovery projects in the pharmaceutical industry, helping pharmaceutical enterprises to achieve the dual goals of exhaust emission standards and organic solvent resource recovery.
