Dry Quenching Columns

The CDQ column is a key equipment in the oil refining unit, which is mainly used to separate and purify coke and impurities in petroleum raw materials. Its working principle is to inject petroleum raw materials into the coke quenching column under the action of high temperature and high pressure, and use the separation device in the coke quenching column to separate the coke and impurities in it.

The CDQ column is composed of multiple components, including a feeding system, a heating system, a separation system, and a slag discharge system. Among them, the feeding system is responsible for transporting the petroleum raw materials into the quenching column, the heating system provides a high-temperature and high-pressure working environment, and the separation system separates the coke and impurities from the oil through the separation device inside the equipment. Finally, the slag removal system discharges the coke and impurities out of the quenching column to ensure the normal operation of the equipment.

CDQ columns play a vital role in the refining process, which can effectively improve the quality and purity of petroleum products. By separating and purifying petroleum raw materials, the content of coke and impurities in the product can be reduced, thereby improving the combustion efficiency and use value of the product. Therefore, the stable operation and operation of the CDQ column are essential for the normal production of the refinery.
