Improvement of determination method of oxygen compounds in liquefied gas
A method for the determination of oxygen-containing compounds in propylene,alkylation and dehydrogenation feedstocks was developed by gas chromatography with loox column separation,the influence of column temperature on the results was studied.The optimum operating conditions were determined.The detection limit,repeatability and accuracy of the method were also investigated.Compared with the original method,the improved method has good separation effect and can expand the detection range.The results show that the method can be used to determine the oxygen-containing compounds in propylene and ether.
