MAN PROBLEMS
OF DFP PRODUCTION

1 Units, common on the territory of the Russian Federation carry out a simple atmospheric fractioning of oil and SGK, without changing the composition of hydrocarbons.
2 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
3 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 SGK at atmospheric units is low-profitable.

THE PROCESS OF CATALYTIC DEWAXING ALLOWS OBTAINING QUALITATIVE COMMERCIAL PRODUCTS

каталитическая депарафинизация
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.
каталитическая конверсия углеводородов
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.
сырье для переработки
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 a raw material for processing.

HOW THE PROCESS
OF CATALYTIC DEWAXING

IS CARRIED OUT TECHNOLOGICAL PROCESS OF CATALYTIC CONVERSION OF HYDROCARBONS IS CONDUCTED AT CONVENTIONAL ATMOSPHERIC PRESSURE AND PROVIDED BY DEPRESSOR CATALYST ON THE BASIS OF HIGH-CRYSTAL MOLECULAR SIEVE

Депарафинизация
ДDewaxing is the process of removing of normal paraffin hydrocarbons from kerosene gas oil and oil fractions of oil.
реакции каталитического крекинга
In the dewaxing process, the catalytic cracking and isomerization of long chain n-paraffins simultaneously occur.
крекинг и изомеризация молекул
In the process of cracking and isomerization, the molecules branch out and shorten without changing the composition, but with a decrease in the molecular weight, which leads to a decrease in the pour point of the DT.
