VOCWaste gas treatment equipmentActual Processing Efficiency Measurement | Range of Actual Removal Rates under Different Operating Conditions
Enterprises are purchasing VOCswaste gas treatmentOne of the most concerning indicators when it comes to equipment is processing efficiency. The actual removal rates of different processes vary greatly under different operating conditions. The following is the range of measured data in actual projects for your reference.
activated charcoalThe removal rate of adsorption equipment is closely related to the saturation state of activated carbon. The newly replaced activated carbon has an initial removal rate of over 90%. As the adsorption capacity increases, the removal rate gradually decreases. When activated carbon approaches saturation, the removal rate may drop below 50%, and even desorption may occur, with outlet concentration higher than inlet concentration. In actual operation, the average removal rate is usually between 60% and 80%, but fluctuates greatly.
The removal rate of catalytic combustion equipment is relatively stable. Under design conditions, the removal rate of fresh catalyst can reach over 95%. As the catalyst ages, the removal rate gradually decreases. After one year of use, the removal rate may decrease to 80 to 90%. Catalyst poisoning or carbon deposition can lead to a significant decrease in removal efficiency. The average removal rate in actual operation is usually between 85% and 95%.
The removal rate of thermal storage oxidation equipment is the highest among several processes. Well designedRTOThe removal rate can reach over 95% in a two bed configuration, and over 98% in a three bed or rotating configuration. In actual operation, as long as the combustion temperature is maintained above 800 degrees Celsius, the removal rate is very stable. For exhaust gases containing difficult to oxidize components such as halogens, the removal rate may be slightly lower.
The removal rate of membrane condensation recovery equipment is closely related to the inlet concentration and condensation temperature. For high concentration exhaust gases with an inlet concentration of over 10 grams per cubic meter, the overall removal rate of three-stage condensation and membrane separation can reach over 98%, and the outlet concentration can be reduced to below 50 milligrams per cubic meter. For medium concentration exhaust gases with an inlet concentration of 2 to 5 grams per cubic meter, the removal rate ranges from 95% to 98%. For low concentration exhaust gases with an inlet concentration of less than one gram per cubic meter, the removal rate will decrease to 80 to 90 percent. The state of the membrane component can also affect the removal rate, and the new membrane has the best performance, with a slight decline after three years of use.
The above data comes from third-party testing reports in actual projects. It should be noted that the removal rate is not a fixed value, but is related to various factors such as exhaust gas composition, inlet concentration, operating parameters, and equipment status.
