What is Atmospheric Residue?
Many products are produced from crude oil. Crude oil products are very important for the global economy. These products are sent to businesses by supply companies. Raw material sales and logistics are done. Atmospheric residue is one of them and is an important raw material.
Atmospheric residue is formed by the distillation of crude oil. After distillation, a sub-product is formed. This product is defined as an atmospheric residue. It is the substance that remains after the volatile substance has been distilled at atmospheric pressure.
It consists of all components of crude oil with boiling points above about 343C. Atmospheric residue, one of the components of crude oil; It is also called atmospheric bottoms, atmospheric resid, reduced crude, long residue, atmospheric reduced crude or topped crude.
How is Atmospheric Residue formed?
This substance is not evaporated because if it evaporates it will begin to crack and disintegrate. Therefore, the main process is atmospheric distillation. In this way, they remain in a liquid state.
Next is the vacuum distillation process. This is a secondary distillation tower. Here it is distilled without cracking. Appropriate temperature is required to prevent fragmentation. If it breaks down, the distillate products become discolored.
Atmospheric raw towers operate at high breakpoints. The cold quenching process minimizes cracking. In this way, the residual holding time is minimized. From here, Atmospheric Residue is sent to the fuel pool. This pool is the forerunner of several graded finished fuel products.
Other options for this flow in a modern refinery include:
• A vacuum distillation unit is fed
• A thermal cracker is fed
• A deep oil fluid feeds the catalytic cracker
• A hydrocracker or hydroprocessor is fed
Where is Atmospheric Residue used?
Atmospheric residue produced from crude oil is delivered by supply companies. It is used in different industries. It is an important raw material for the global economy. Raw material suppliers do the logistics of this raw material. Widely used for vacuum distillation units. Its job here is to feed. It should not be confused with Heavy Fuel Oil.
