Product Introduction
Isodewaxing Catalyst For Diesel Hydrogenation Dewaxing Unit
Based on the diesel isomerization dewaxing technology that developed by FRIPP, the designed isodewaxing catalyst(Pt) with excellent properties can improve the low temperature fluidity of diesel and produce high quality and low freezing diesel.
According to the technical documents that offered by end user, the technical solution and catalyst were recommended based on results of previous medium scale testing and successful industrial applications.
In the document, the unit has 2 blocks: (1) diesel fuel hydrotreatment unit takes place in a hydrogen environment(hydrodesulfurization, denitrogenation, hydrogenation of aromatic and unsaturated hydrocarbons) ; (2) dewaxing unit is designed to achieve the required cloud point and required density in the production of winter product diesel fuel.
Design capacity of feedstock 2,500 thousand tons/year with operation range 60~110% and 8,760 hours of work per year.
The process flow of dewaxing block is bottom product of high-pressure stripper reduces the freezing point of diesel in the dewaxing block, after gas liquid separation and fractionation to get low freezing diesel and naphtha.
