Catalytic cracking gas analysis V%
Thread Content
Teacher, please tell me how to analyze the content of the following gases in dry gas and rich gas, as well as the control indicators of these gases and how to calculate the volume of V%. The content of each gas indicates those phenomena. Methane, ethane, ethylene, propane, propylene, isobutane, n-butane, cis-butene, trans-butene, Carbon 5.> Carbon 5, hydrogen, oxygen, carbon dioxide, nitrogen.CO, hydrogen sulfide Thank you!!!
Analyze with gas chromatograph. For catalytic cracking, the C3 component in dry gas and rich gas can be examined in the operation of the absorption tower. H2/CH4 in dry gas can evaluate the poisoning of the catalyst. Air components (N2, O2, CO2) are generally used to examine the degassing effect of the regenerator. For coaxial devices, it can also be used to determine whether there are hidden dangers such as whether the two regenerators are connected. C3 in dry gas is generally no more than 5%, but now it seems that the requirement is no more than 3%. In addition, the dry gas composition and liquid hydrocarbon composition can be calculated together to determine the hydrogen transfer reaction trend. In short, this thing is very useful. You can check the relevant information.
