Modular Crude Oil Refinery

Akfen Engineering is a company with successful partnerships with its customers in the establishment, installation, personnel training and commissioning of the plant in central Asia, Europe and Africa in the installation of modular crude oil refineries.

Modular crude oil atmospheric distillation unit are changing modular systems with a capacity ranging from 1,000 BPD - 10,000 BPD.

Modular Crude Oil (Petroleum) Refineries and Operation Principles of the System

• 1- Cross-Section Distillation (Batch Type)
• 2- Continuous Distillation (Pipe Still)

Crude oil (Petroleum) consists of the fusion of hydrocarbons, which have molecular weight and boiling point of many different types. These hydrocarbons are delivered to widely spaced boiling points by distillation process and separated into fractions as follows:

• 1- Gas
• 2- Naphtha
• 3- Gas Oil
• 4- Diesel Oil
• 5- Heavy Fuels (Fuel Oil)

Distillation

Distillation is the process of enabling crude oil to evaporate partially at high temperature and then separating it by condensing again according to the temperature. We decompose suitable derivatives with the help ofan atmospheric distillation column. The system performs multiple distillation fractionation.

Fractionation

Evaporation begins with the introduction of crude oil (petroleum) into the column. The evaporated oil rises according to its density and passes through the tray holes and through the filling material. . The part that does not evaporate (the remaining part of the liquid) descends to the lower part of the column. This process is called fractionation (phase separation).

The distillation column consists of 3 parts.

• 1-) Flash Part (The Part Where Crude Oil Enter)
• 2-) Lower-Part Reboiler (Raw Oil Spill Zone)
• 3-) Upper Part (Fractional Part)

The flash part is the first part where crude oil (petroleum) enters the column.Crude oil (petroleum) coming from the furnace with high pressure and temperature enters the column. by coming from the furnace with high pressure and temperature.. Meanwhile, a pressure drop occurs. Due to the pressure drop and high temperature, hydrocarbons with a low boiling range evaporate in the oil, moving to the upper parts of the column and the decomposition process begins.

The lower part separates the light parts that are not desired to remain in the products at the buttom. This separation process is realized either by giving with the hot oil system from the bottom or by reheating(reboiler)

The upper part is the fractional part and the desired products are obtained from this part.

In the modular crude oil (petroleum) distillation project, manufacturing, assembly, training and commissioning processes are  execuded by our company with our experienced staff and consutants by taking into account the basic principles of the process. In order to run and operate the process, the staff support, and training requested by our customers are provided.
