Повышение эффективности процесса стабилизации на установке каталитической депарафинизации средних дистиллятов

Abstract

The aim of this work is to optimize the operation parameters and scheme of stabilizer (a part ofcatalytic dewaxing unit) so that to improve the removing of hydrogen sulphide from the product of the unit. Toachieve this aim the model of stabilizer was developed and the research of operational parameters influence onthe degree of hydrogen sulphide removal was conducted. The computational results show that optimaltechnological scheme includes recycle of stable gasoline from rectification section and hydrogen-containing gasinjection into the column. This allows achieving complete removal of hydrogen sulphide from the product and, asa result, decreasing its corrosive activity and improve quality in the context of ecology.
