Product introduction

Effect of feed distribution on needle coke production

In a coke tower without a feed distributor installed, the feed port is located in the center of the bottom cover of the coke tower, and the feed channel is located in the center of the coke tower. Because the feed pipe is thinner and the diameter of the coking tower is thicker, it takes a long time for the material to flow to the tower wall as it diffuses around after feeding. In this process, on the one hand, due to the large scattering surface and the long diffusion time to the periphery, the light components in the system overflow faster. The greater the distribution to the periphery, the greater the viscosity of the system, it is not easy to create and merge mesophase spheres. And the more to the periphery, the greater the viscosity of the system, the smaller the light component, resulting in insufficient oil and gas, resulting in poor structure of coke, especially tower coke. On the other hand, because of the long diffusion time, the radial temperature distribution in the coking tower is not uniform, which is not conducive to the reaction.

By changing the feed pattern at the bottom of the coke tower, the feed is diffused around and the feed channel is formed between the center of the coke tower and the wall of the tower. Hydrogenation Project,Hydrogen Production Eguipment,Heating Furnace Equipment The advantages are as follows: When the material enters the coke tower, it is quickly covered by the radial layer of the coke tower. The homogeneous temperature distribution and viscosity of the material create favorable conditions for the growth and melting of mesophase spheres. The wide distribution of feed channels not only creates favorable conditions for blowing oil and gas, but also improves the poor quality of tower wall coke

Product parameter

Name: Needle coke heating furnace

Application: petrochemical industry

Design temperature: ≤800℃

Megawatt: 5-50 MW/unit

Specification：：Cylinder diameter 2-8 meters

The square can be customized in length, width and height

Note:

1. before opening the furnace should be furnace tube, parts, ancillary equipment, process pipelines, instruments and other instruments for a comprehensive inspection, confirm the process is correct, all equipment and parts intact, equipment and pipelines without debris, instruments and instruments flexible and convenient operation, real and accurate data;

2. Steam through the process pipeline and equipment of the furnace system to ensure smooth process flow. When all checks are qualified, the fuel gas line shall be completely replaced with nitrogen and then introduced to the fuel gas line. When fuel gas is introduced, pay attention to the oxygen content of air in the pipe <1%. Before ignition, the content of combustible gas in the fuel gas pipeline is detected, and the ignition operation is carried out after the ignition conditions are met.

3. Use steam stoves in strict accordance with operating rules;

4. Heating, close the steam valve, such as furnace and pressure, must be able to wait for the pressure to zero inch after the pot (box) to take.

Compared with other companies, the advantages of our products are: good thermal insulation effect, high thermal efficiency, good energy saving effect, low smoke exhaust temperature, adjustable dilution ratio, good selectivity, less high boiling substance; Emission standards, small pollution, small footprint.

Product process: blanking, assembly, welding, testing, anti-corrosion, installation, commissioning.
