Abstract

In this work forecast calculation of stabilizer column in the technology of low-pour- point diesel fuel production was modelled. The results of forecast calculation were proved by full-scale experiment at diesel fuel catalytic dewaxing unit. The forecast calculation and full- scale experiment made it possible to determine the ways of mass transfer intensification, as well as to increase the degree of hydrogen sulphide removal in the column, and thereby to decrease corrosiveness of the product stream. It was found out that maintenance of the reflux rate in the range of 80-90 m3/h and injection of additional vapourizing streams, such as stable naphtha from distillation unit (in the volume of 10-22 m3/h) and hydrogen-containing gas (in the volume of 100-300 m3/h), ensure complete elimination of corrosive hydrogen sulphide from the product stream. Reduction of stream corrosive activity due to suggested solutions extends service life of equipment and pipelines at industrial catalytic dewaxing unit.
