The selection of treatment technology should be based on the gas volume, purification requirements, the possibility of recovery, the economy of equipment construction and operation and other conditions. Special attention should be paid to the close cooperation with the process in practical work, so as to achieve comprehensive utilization as far as possible.
At present, there are three common methods of organic waste gas treatment at home and abroad: liquid absorption method, activated carbon adsorption method and catalytic combustion method.www.powdered-activated-carbon.com
The purification efficiency of liquid absorption method is 60%~ 80%, which is suitable for treating low concentration and large volume of organic waste gas, but there are secondary pollution.pelletized activated carbon
The purification rate of catalytic combustion method is 95%, which is suitable for the treatment of high concentration and small air volume organic waste gas. The disadvantage is that it has strict requirements on the treatment object and requires high gas temperature. In order to improve the exhaust gas temperature, it needs to consume a lot of fuel, so the operation cost is very high.In domestic has been eliminated. Specific surface area test unified the multi-point BET method at home and abroad, specific surface area measurement standards are developed at home and abroad is based on BET test method, please see our national standard (GB/T 19587-2004) - gas adsorption BET principle of solid material specific surface area measurement methods. Specific surface area testing is actually the more time-consuming jobs, as the adsorption capacity of sample is different, some sample testing may need to spend the whole dayTime, if the test process is not fully automated, the tester can not leave at any time, and should be highly focused, observe the dashboard, control the knob, a little careless will lead to the failure of the test process, which will waste a lot of valuable time of the tester.
F - Sorb 2400 specific surface tester is really able to BET method detection instruments (both direct comparison method), the more important F - Sorb 2400 specific surface tester is by far the only specific surface area of the fully automated intelligent testing equipment, the test results with the international high consistency, the stability is very good also, at the same time reduce the human error, improve accuracy test results.
