Vacuum technology used in chemical process is a problem to be considered at present. It is not always easy to choose a suitable vacuum pump for chemical process application. First, the vacuum system must provide the required pump speed under the working pressure to ensure the required vacuum time. Secondly, it can not be sensitive to process gas, and all requirements must be met when it is used for CIP (in-situ cleaning) cleaning and gas recovery. In addition, stability and economic efficiency also play an important role in determining which vacuum technology to use. In this article, we will talk about vacuum pumps for hydrocarbon removal.
What are hydrocarbons?
Hydrocarbons are one kind of organic compounds. This compound consists of only carbon and hydrogen, including alkanes, olefins, alkynes, cyclohexanes and aromatics, and is the matrix of many other organic compounds.
vacuum pump for remove hydrocarbon selection:
Due to the different working conditions in practical production and application, there will be many changes in the inhalation gas and pressure, so when selecting the type, it should be checked and calculated according to the actual exhaust process, gas release process, condensation of condensable gas, time variation of inhalation pressure, etc. or the use of existing equipment.
According to the application scope, vacuum pump can be divided into rotary vane vacuum pump, roots vacuum pump and screw vacuum pump. Vacuum pump is a kind of rotary variable capacity, which plays an important role in the application scope of vacuum pump. Vacuum pumps are widely used in food processing, manufacturing, aerospace and metallurgical industries.
Vacuum pump advantages:
1. The two compression stages are stacked together and interconnected, which is helpful for initial compression of process gas in the first stage and secondary compression in the second stage, so that lower limit pressure can be achieved.
2. Vacuum pumps are lubricated by oil, which means that a certain amount of working fluid, oil or other compatible liquid is injected into the compression chamber. In contrast, other rotary vane vacuum pumps use oil cycle lubrication.
3. Vacuum pumps are water-cooled so that they can adjust their working temperature in a specific range.
Vacuum pumps are widely used to remove hydrocarbons because of their cleanliness, non-pollution, wide pumping speed range, good energy saving, stability and easy maintenance.
In this paper, the vacuum pump for hydrocarbon removal is discussed. It is necessary to select the right vacuum pump. Therefore, it is important to consult vacuum experts and consider all important parameters in the processing process, including processing conditions, process gases, integration related to process control, and energy efficiency, safety and stability of future vacuum generation. Usually, as long as these factors are considered, a suitable vacuum system can be customized directly according to the requirements.
