In industrial production, the treatment of high-concentration VOC (volatile organic compound) exhaust gases has long been a challenging issue. These exhaust gases not only cause severe environmental pollution but may also pose a threat to human health. At present, there are a variety of processes on the market to deal with high concentration of VOC waste gas, the following is a detailed comparison of several mainstream processes.
Activated carbon adsorption is a common VOCwaste gas treatmentMethod. Its principle is to use the porous structure of activated carbon to adsorb the organic matter in the exhaust gas on its surface. However, this process has many drawbacks. Many companies use activated carbon equipment and have to replace the carbon once a month. Each replacement, along with hazardous waste disposal, involves cumbersome procedures and high labor costs. Moreover, activated carbon adsorption merely transfers the organic compounds from the exhaust gas into the carbon, without truly resolving the underlying issue. The replaced waste carbon can not be thrown away, and qualified companies should be asked to take it away, which undoubtedly increases the operating cost and management difficulty of the enterprise.
The RTO equipment has a good effect on treating exhaust gas. It decomposes VOC exhaust gas into carbon dioxide and water through high-temperature combustion. However, the operating cost of RTO is relatively high, especially when treating low-concentration exhaust gas, it needs to continuously supplement natural gas, and the burned gas is more valuable than the recovered solvent. If the operating load is reduced, emissions will still fail to meet the standards. When many enterprises use RTO process, they often face the problem of unbearable operating costs, which has a great impact on the economic benefits of enterprises.
Wohong PetrochemicalThe membrane condensation recovery unit uses three-stage condensation plus.gas separation membraneCombination process for high concentrationVOC waste gas treatmentA new solution is provided. This process has many advantages and is suitable for the treatment of medium and high concentration organic waste gas in chemical, pharmaceutical, gas station and other industries.
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 burning gas, the membrane condensation recovery process has obvious advantages in operating costs, which can save a lot of operating costs for enterprises.
The equipment can be the waste gas in the organic solvent condensation liquefaction recovery, recovery purity can reach more than 90%. The recovered solvent can be directly reused in production or sold to external customers, thereby converting environmental protection expenditures into economic benefits. This not only reduces the waste of resources, but also brings additional economic benefits to enterprises, and achieves a win-win situation for environmental protection and economy.
The service life of the core consumable membrane module is three to five years. Daily maintenance primarily involves weekly checks of the refrigeration system pressure and the recovery liquid level, monthly cleaning of the heat exchanger fins, and annual replacement of the refrigerant oil and the dryer filter, eliminating the hassle of frequent consumable replacements. Compared with the problem of frequent carbon exchange in the activated carbon adsorption process, the membrane condensation recovery process has greatly improved the maintenance cost and management difficulty.
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, it also has explosion-proof configuration options, suitable for chemical, pharmaceutical and other explosion-proof places, a wide range of applications.
Relying on the R & D platform of Henan Oil and Gas Recovery Engineering Technology Research Center, Wohong Petrochemical has set up a professional scientific research, manufacturing and marketing team, which can customize equipment according to customer working conditions and provide complete support from the early stage to the late stage. Provide free working condition research and exhaust gas composition analysis in the early stage, and issue targeted technical solutions and investment payback period calculations; provide equipment manufacturing, factory testing, transportation, installation guidance, commissioning and operator training in the medium term; provide one-year warranty, spare parts supply, remote technical support and regular inspection services in the later stage.
In the choice of high concentration VOC waste gas treatment, enterprises need to consider the operation cost, treatment effect, resource recovery and other factors. With its unique advantages, Wohong Petrochemical's membrane condensation recovery process provides enterprises with an efficient, economical and environmentally friendly solution, which is worthy of the attention and choice of enterprises.
