In the context of today's increasingly stringent environmental requirements,waste gas treatmentIt has become an important issue for many enterprises. The complexity of the exhaust gas composition has a vital impact on the treatment effect, and also determines the treatment process for different pollutants.
The composition of waste gas is varied, and the chemical and physical properties of different components are very different, which is directly reflected in the difficulty and effect of treatment. The first is the particulate matter in the exhaust gas, which will cause wear and blockage to the processing equipment, reducing the operating efficiency and service life of the equipment. For example, some dust particles contained in industrial waste gas may affect the normal operation of the subsequent treatment process if they are not removed by pretreatment.
Some exhaust gas components are highly corrosive, such as sulfur and chlorine-containing exhaust gas, which will cause corrosion to equipment materials, resulting in equipment leakage and damage, which not only affects the treatment effect, but also may cause safety accidents. In addition, different organic components in the exhaust gas have different boiling points, volatility and other characteristics, and their adaptability to condensation, adsorption and other treatment processes is also different. Low-boiling organics may require lower temperatures during the condensation process, while high-boiling organics may be more easily captured by the adsorbent material during the adsorption process.
Next, we look at the process adaptability of different pollutants. For common hydrocarbons, esters, ketones, alcohols, halogenated hydrocarbons and other organic solvent waste gas, membrane condensation recovery process is a good choice. With LuoyangWohong PetrochemicalTaking the membrane condensation recovery unit of Equipment Co., Ltd. as an example, it adopts a three-stage condensation processgas separation membraneThe combined process has a good recovery effect on these common organic solvents. The process is suitable for the treatment of medium and high concentration waste gas in chemical, pharmaceutical, printing, coating, electronics, gas station and other industries. Its skid-mounted integrated design, small footprint, fast installation, operation only electricity without burning gas, can effectively reduce operating costs. Moreover, the equipment can also condense and liquefy the organic solvent in the waste gas for recovery, and the recovery purity can reach more than 90%. The recovered solvent can be directly reused for production or external sales, and the environmental protection expenditure can be converted into economic benefits.
activated charcoalThe adsorption process is also a commonly used waste gas treatment method, but it also has its limitations. Many enterprises use activated carbon equipment, and 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. In contrast, the service life of the core consumable membrane components of the membrane condensation recovery unit of Wohong Petrochemical Company is three to five years. The daily maintenance is mainly to check the pressure and recovery liquid 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.
RTO(Regenerative thermal oxidation furnace) The equipment has good effect on waste gas treatment, but the gas consumption is high. Especially when dealing with low-concentration exhaust gas, it is necessary to continuously supplement natural gas, and the value of the burned gas is higher than that of the recovered solvent. If the operating load is reduced, emissions will still fail to meet the standards. However, the equipment operation of Wohong Petrochemical only consumes electricity. The refrigeration compressor and vacuum pump are controlled by frequency conversion, and the power is automatically adjusted according to the exhaust gas load, thus effectively controlling the power consumption and avoiding the problem of high operating cost.
LuoYang WoHong Petrochemical Equipment Co., Ltd., leveraging the R&D platform of the Henan Provincial Engineering Research Center for Oil and Gas Recovery, has assembled a dedicated team specializing in research, manufacturing, and marketing. They can according to the different composition of exhaust gas, from the early free working condition research and exhaust gas composition analysis, according to the concentration, air volume, composition of the three core parameters to issue a targeted technical plan and investment recovery period calculation. Provide equipment manufacturing, factory testing, transportation, installation guidance, commissioning and operator training in the medium term, and provide full-process services such as one-year warranty, spare parts supply, remote technical support and regular inspection services in the later period.
The influence of exhaust gas composition on the treatment effect can not be ignored. When enterprises choose the exhaust gas treatment process, they need to fully consider the characteristics of the exhaust gas composition and choose the most suitable treatment process. With its advanced technology, high-quality products and perfect services, Wohong Petrochemical provides enterprises with a reliable waste gas treatment solution to help enterprises achieve green and sustainable development.
