Diesel blending

To make diesel fuel with high performance and optimal hydrocarbon content, modern methods of component content measurement are required.

It seems impossible to achieve without using additives. Additive efficiency depends to a large extent on the hydrocarbon composition of diesel. Additives for diesel fuel are mostly selected by trial and error. This stage is one of the most problematic for fuel producers. The main difficulty is combining...

Diesel Fuel Production. Catalytic deparaffinization is increasingly used in oil refining due to its efficiency and technical simplicity. Experience shows that catalytic deparaffinization can be successfully integrated with deep hydrodesulfurization.

Let us briefly look at systems used for such processes. In 2003, hydrodewaxing equipment was first used. The equipment included a sulfur production section. The raw material for the process is a high paraffin content straight run...

Diesel Fuel Blends. Modern oil refining performs several important functions, among which improvement of the low temperature performance of diesel fuel performance and increased depth of hydrofining.

Until recently, the production of fuel with good low temperature performance was done by either reducing the end of fuel boiling from 360ºС to 340ºС (330ºС for arctic fuel), or by dilution with kerosene. In both cases, the economic viability...

Until recently, the phrase “diesel fuel for cars” could bring a smile to the faces of experienced drivers.  This is not surprising, because this oil was used mainly to fuel trucks and large special equipment.  But due to the significant progress in refining processes and engine manufacturing it has become possible to use diesel fuel in cars.

The issue which has always worried each driver is the...

Most frequently used diesel fuel production process includes several steps: treatment in distillation columns, cracking and compounding process.

Processing in distillation columns is the first step which is necessary for diesel fuel production.  Oil is heated at constant pressure up to the temperature of 180-360ºC.  This makes it possible to divide “black gold” into separate fractions.  The finished fuel outlet after processing in distillation columns is relatively...

Rough running of an engine can be caused by different reasons.  The first one is injection timing control disturbance.  The second one is incorrect operation of the fuel equipment.  In both cases it is advisable to visit a service station and have the car examined by specialists.

Another possible reason of rough running is refueling with low-cetane fuel.  This parameter characterizes the ability of diesel fuel to...

The history of a diesel engine dates back to the previous century, when Rudolf Diesel proposed a fundamentally new design that converts fuel combustion energy into mechanical energy.  After many years, diesel engine has not lost its relevance and began to enjoy increasing popularity.  The reasons are obvious: the fuel for a diesel engine is relatively cheap and it is more environmentally friendly.

Moreover, modern diesel engines...

Diesel fuel is produced in refineries using special technological processes: primary and secondary processing of oil, as well as compounding (blending).

Primary processing is required to separate oil into individual fractions that have different boiling points.

Technically, this process is performed in special distillation columns.  One of the results of primary distillation are diesel fractions that are then used in diesel fuel production.

Secondary distillation...

Good performance of diesel engines requires high quality fuels.  But in practice, it is not so simple to find it.  The purchased fuel may be inadequate in terms of cetane number, may be contaminated and unadapted for use at different periods of the year.  In the case of use of low-quality diesel fuel, the condition of engine can deteriorate, which may lead to its failure over time.
