Olefin content in the product gasoline
Thread Content
Recently, the gasoline produced in the workshop has had an excessive level of olefins; could the more experienced colleagues offer some guidance? What measures should be taken?

The olefin content in hydrogenated gasoline is not within the specified limits; it is necessary to consider what analysis methods should be used to obtain the relevant data Sometimes, the accuracy and precision of analytical methods have a significant impact on the data. If composition analysis is carried out using chromatography, then there are basically no issues with such data. However, if the data are obtained through bromine value determination, it is necessary to consider that incomplete removal of hydrogen sulfide from the oil during stripping after gasoline hydrogenation can affect the determination of olefins. If fluorescence method is used for measurement, it may be due to insufficient precision in the measurement (that is, inaccurate reading of the scale values).
