Alkylation process
Thread Content
Urgent: Does anyone know about alkylation units? During the analysis of all components in raw material C4, do inert gases need to be included in the calculations as well? If anyone knows, please let me know, urgently. Thank you
Do it with different machines. The composition of liquefied gas is normalized by area. Dimethyl methyl ether is analyzed using a volume internal standard method. Nitrogen and carbon dioxide are detected using a thermal conductivity cell
Since it is a full-component analysis, all components in the sample must be included in the calculation of their concentrations; otherwise, it can’t be called a full-component analysis. Of course, in the actual analysis process, the different properties of the components result in varying responses at the detector; therefore, it is necessary to apply appropriate corrections to the different detectors or use suitable standards or calibration methods to achieve accurate quantification. In my opinion, for the analysis of carbon-4 feedstocks, if it is necessary for manufacturing processes, it is possible to overlook the analysis of the very small amounts of permanent gases present in the feedstock, although these components may become somewhat concentrated over the course of production. However, when conducting trade analysis on the raw materials entering the plant or testing their quality, it is necessary to take into account the content of these permanent gases, as what you are purchasing is carbon 4 raw material, not those permanent gases that have no practical value.
