In the process of industrial production, the treatment of VOC (volatile organic compound) waste gas has always been an important topic in the field of environmental protection. Different VOCsWaste gas treatment equipmentTechnical routes have their own characteristics, the following is a detailed introduction to the common process and its advantages and disadvantages.
Activated carbon adsorption is a widely used VOCwaste gas treatmentProcess. Its working principle is to use the porous structure of activated carbon to adsorb the organic matter in the exhaust gas on its surface. The advantage of this process is that the equipment is simple, the investment cost is relatively low, and it has a good treatment effect on the low concentration of VOC waste gas. However, it also has significant drawbacks. When many enterprises use activated carbon equipment, they have to change carbon once a month. Each time they change carbon and dispose of hazardous waste, the procedures are complicated and the labor cost is high. Moreover, activated carbon adsorption merely transfers the organic compounds from the exhaust gas into the carbon, without truly resolving the underlying issue.
The RTO process decomposes VOC exhaust gas into carbon dioxide and water through high-temperature combustion. It has the advantage of high treatment efficiency, can effectively reduce the VOC content in the exhaust gas, and is suitable for high concentration and large air volume exhaust gas treatment. However, the operating cost of RTO equipment is high, especially when dealing with low-concentration exhaust gas, it is necessary to continuously supplement natural gas, gas consumption is large, and the burned gas is more valuable than the recovered solvent. If the operating load is reduced, the emission may not meet the standard.
Among manyVOC waste gas treatmentIn technology, the membrane condensation recovery process is a more advanced and has many advantages of the technical route. With LuoyangWohong PetrochemicalTaking the membrane condensation recovery unit of Equipment Co., Ltd. as an example, it adopts a three-stage condensation processgas separation membraneCombination process, suitable for the treatment of medium to high concentration organic waste gases in industries such as chemical, pharmaceutical, and gas stations.
The equipment only consumes electricity, and the refrigeration compressor and vacuum pump are controlled by frequency conversion, which can automatically adjust the power according to the exhaust gas load and effectively control the power consumption. Compared with the high cost of RTO combustion, it has obvious advantages.
The equipment can condense and liquefy the organic solvent in the waste gas to recover, and the recovery purity can reach more than 90%. The recovered solvent can be directly reused for production or external sales, converting environmental protection expenditures into economic benefits, and solving the problem of waste of resources and increased environmental protection costs caused by the burning or adsorption of solvents in the exhaust gas.
The core consumable membrane module has a service life of three to five years. Daily maintenance is mainly to check the pressure and recovery level of the refrigeration system every week, clean the heat exchanger fins every month, and replace the refrigerating oil and drying filter every year. There is no trouble of frequent replacement of consumables.
All components of the equipment are integrated onto a single stainless steel base and are assembled and tested prior to leaving the factory. At the site, simply connect the power supply and air ducts to start using it; installation is quick, and it occupies a small footprint. Moreover, an explosion-proof configuration is also available, making it suitable for hazardous environments such as chemical and pharmaceutical facilities.
This equipment has good recovery effects on common organic solvents such as hydrocarbons, esters, ketones, alcohols, and halogenated hydrocarbons. It is suitable for medium to high concentration waste gas treatment scenarios in industries such as chemical, pharmaceutical, printing, coating, electronics, and gas stations. It can also be customized according to customer working conditions.
Relying on the R & D platform of Henan Oil and Gas Recovery Engineering Technology Research Center, Luoyang Wo Hong Petrochemical Equipment Co., Ltd. has set up a professional scientific research, manufacturing and marketing team, which can provide the whole process service from working condition analysis to equipment delivery. In the early stage, free working condition investigation and exhaust gas composition analysis will be provided, and targeted technical plans and payback period calculation will be issued according to core parameters. In the medium term, equipment manufacturing, factory testing, transportation, installation guidance, debugging and operator training will be provided. In the later period, one-year warranty, spare parts supply, remote technical support and regular inspection services will be provided. Customers can also sign long-term maintenance contracts as required.
in the choiceVOC Waste Gas Treatment EquipmentAt the same time, enterprises should choose the most suitable technical route and equipment according to their own exhaust gas characteristics, treatment requirements and economic strength. With its unique advantages, the membrane condensation recovery equipment of Wo Hong Petrochemical is undoubtedly a high-quality choice for many enterprises to deal with VOC waste gas.
