OF DFP PRODUCTION
Most units located on the territory of the Russian Federation perform simple atmospheric fractioning of oil and SGC, without changing the composition of hydrocarbons.
Diesel fractions usually contain a lot of paraffins, which leads to a high temperature of solidification of diesel fuel and makes it unsuitable for use at low temperatures
DF provides profitability of production, but when trying to produce a winter diesel fuel, its losses reach 50%. Therefore, to date, a simple distillation of oil and SGC at atmospheric units is low-profitable.
THE PROCESS OF CATALYTIC DEWAXING ALLOWS OBTAINING QUALITY PRODUCTS
To reduce the pour point of the DF, it is necessary to remove n-paraffins from its composition. This goal is achieved through catalytic dewaxing.
The technological process is based on the catalytic conversion of hydrocarbons to obtain the maximum quantity of high-quality light products. Previously, these processes were used only in large state-owned enterprises.
Any hydrocarbon with a boiling point of 140-360 °C (light fuel oil, furnace fuel, heavy diesel, paraffins, low-viscosity marine fuel, etc.) can be used as raw material for processing.
