How to choose between single process and combination process? What situations are more suitable for using a combination process?

In the field of waste gas treatment, enterprises often face the choice of single process and combination process. So, how to choose, which situation is more suitable for the use of combined process.

A single process refers to the use of a treatment method to solve the exhaust gas problem. Its advantages are that the operation is relatively simple, the equipment structure is not complicated, and the construction cost and maintenance difficulty in the early stage may be relatively low. However, it also has obvious limitations. A single process is often only for a specific type, specific concentration of exhaust gas to play a better effect, for the composition of complex, unstable concentration.waste gas treatmentThe effect may not be satisfactory, and it is difficult to realize the effective recycling of resources in the exhaust gas.

The combined process combines two or more different treatment methods to give full play to their respective advantages in order to achieve better exhaust gas treatment results. The combined process can more comprehensively deal with the complex waste gas situation, improve the treatment efficiency, better meet the requirements of environmental protection, but also can recover the organic solvent in the waste gas, and create certain economic benefits. However, the combined process equipment is relatively complex, the upfront investment may be higher, and the professional level of the operator is also higher.

When the composition of the exhaust gas is complex and contains many different types of pollutants, it is difficult for a single process to effectively treat all pollutants at the same time, and the combined process can adopt different treatment methods for different pollutants. For medium and high concentration of organic waste gas, if only a single process may not achieve the desired treatment effect, but also cause a waste of resources. The combined process can first recover most of the organic solvent by condensation and other methods, and then carry out further purification treatment, which can not only reduce emissions, but also realize resource recovery. In the case of high requirements for the treatment effect, such as very strict emission indicators, or the need for high-purity recovery of the solvent in the exhaust gas, the combined process can meet more stringent standards by virtue of its synergy.

LuoyangWohong PetrochemicalLtd. focuses on the field of VOC waste gas treatment, its main membrane condensation recovery unit using three-stage condensation plus.gas separation membraneThe combined process is suitable for the treatment of medium and high concentration organic waste gas in chemical, pharmaceutical, gas station and other industries, which is the embodiment of the successful application of the combined process in waste gas treatment. The equipment skid-mounted integrated design, small footprint, fast installation, low operating costs, but also to recover the solvent in the waste gas to create economic benefits.

When choosing a single process or a combination process, enterprises need to consider the characteristics of the exhaust gas, treatment requirements, investment budget and other factors. In the face of complex waste gas treatment problems, the combination process is often a better solution. With professional technology and rich experience, Luoyang Wo Hong Petrochemical Equipment Co., Ltd. can provide enterprises with more suitable waste gas treatment solutions and help enterprises achieve a win-win situation of environmental protection and economy.
