What types of waste gases can be treated by condensation and gas separation membrane-based waste gas treatment equipment?

Enterprise SelectionWaste gas treatment equipmentThe first thing to confirm is whether the technical route is applicable to the type of exhaust gas generated by oneself. Different VOCs composition, physical and chemical properties vary greatly, not every kind of equipment can be universal. So condensation plusgas separation membraneThis kindwaste gas treatmentWhat kind of waste gas can the equipment handle?

The core principle of condensation plus gas separation membrane technology is to use the difference in saturated vapor pressure of different substances at a given temperature and the difference in the selective permeation rate of organic molecules in the membrane material to achieve separation. Therefore, it is particularly suitable for those organic substances with relatively high boiling points and good condensability. Specifically, this set of exhaust gas treatment equipment is particularly prominent for the following types of exhaust gas.

The first category is hydrocarbon waste gas, including gasoline, diesel, benzene, toluene, xylene, solvent oil, etc. These substances have a high saturated vapor pressure at room temperature and are easily liquefied and recovered by multistage condensation. The second category is halogenated hydrocarbons, such as dichloromethane, trichloroethylene, carbon tetrachloride, etc., which are harmful to the environment and human body, but the condensation recovery efficiency is very high. The third category is oxygen-containing organic compounds, including alcohols such as ethanol, isopropanol, esters such as ethyl acetate, butyl acetate, ketones such as acetone, butanone, etc., which are common industrial solvents with high recovery value.

For low boiling point, difficult to condense substances, such as methane, ethane, or formaldehyde, hydrogen sulfide and other strong polar small molecules, the effect of single condensation and membrane separation is limited. But in the actual industrial waste gas, these substances are often not the main components. LuoyangWohong PetrochemicalWhen designing waste gas treatment equipment for customers, Equipment Co., Ltd. will first conduct laboratory analysis of waste gas samples to determine the composition and concentration, and then determine whether the condensation plus gas separation membrane is applicable. If not applicable, it is recommended to combine other pre-processing units. Therefore, it is very important for enterprises to provide accurate exhaust gas composition information when consulting.

Overall, as long as the exhaust gas contains condensable recovered organic matter, and the concentration reaches more than 1‰, this equipment can play a good treatment effect.
