Horizontal reaction kettle delayed coking equipment and process thereof

Abstract

The invention discloses a piece of horizontal reaction kettle delayed coking equipment and a process thereof, which has small investment, convenience for operation, high security coefficient of work environment and wide application scope of raw material source. The horizontal reaction kettle saves complex corollary equipment and support equipment, and does not need foundation. The investment volume of the horizontal reaction kettle related in the invention is 3-4 hundred thousand yuan, and the total investment volume is greatly reduced relative to vertical reaction kettles, so that the financial burden of enterprises is reduced; the raw material is conveyed and fed via a raw material distribution valve, so that multiple horizontal reaction kettles can be connected; the reaction time and the time for shoving cokes can be arranged by a manner of feeding or discharging the raw material, so that the overall coking processing quantity is proportional to the number of single horizontal reaction kettle which is connected with the raw material; and because of the annular cavity of the raw material distribution valve, the raw material is under the clockwise or anticlockwise flow state, is not easy to coke, and is easy to operate.

Description

technical field [0001] The invention relates to the field of petrochemical technology, in particular to a horizontal reactor delayed coking equipment and a process thereof. Background technique [0002] The early coking industrial installations were kettle coking and flat furnace coking. After the raw materials enter the coking kettle or open hearth furnace, they are heated outside the equipment, which has been eliminated. The delayed coking technology was developed in the 1930s, and the fluidized coking technology was developed in the 1950s, which greatly improved the heating conditions of petroleum coking (the former uses a tubular heating furnace for heating, and the latter uses a part of coke for heating. ). Delayed coking adopts hydraulic decoking, which can significantly improve the efficiency of the device, and is currently the most widely used. At the end of the 1970s, flexible coking formed by combining fluidized coking and coke gasification is also used to some ...

AI Technical Summary

Problems solved by technology

[0006] The coke tower is an empty tube made of thick boiler steel plates. Its height is set at about 30 meters according to the different processing volumes. The steel plate structure makes its weight very large, and it is prone to vibration during work. In order to maintain its standing stability, it is often Auxiliary building facilities need to be built, and the requirements for its foundation are also very high, which increases construction costs and operating expenses, resulting in high construction costs. Taking the annual processing capacity of 1 million tons as an example, the investment in equipment is 240 million In addition, the coking tower adopts a vertical square box furnace coking reactor, which has high requirements on the quality of raw materials, resulting in a narrow source of raw materials.
