Description

Technical Field

[0001] This utility model relates to the field of petrochemical derivatives technology, specifically a gas collection device for petroleum cracking processing. Background Technology

[0002] Gas collection devices for petroleum cracking are crucial equipment in the chemical industry, and their main function is to collect and process the gases generated during petroleum cracking.

[0003] The gas output from existing petroleum cracking is a high-temperature, high-pressure gas. When stored in existing gas storage tanks, the high temperature will affect the storage space. As the gas temperature decreases, it will turn into liquid, further reducing the collection efficiency. In addition, the generated gas contains a variety of impurities that will corrode the tank, which has limitations.

[0004] The reason for this problem is that in existing gas storage tanks, the gas density decreases as the gas temperature rises. This is because high temperatures intensify the thermal motion of gas molecules, increasing the average distance between molecules and causing the gas volume to expand and its density to decrease. This leads to reduced collection efficiency, and thermal expansion also consumes more space. Furthermore, high-temperature, high-pressure gases condense during transportation due to heat loss, forming liquid substances. Additionally, the gas contains various impurities that can cause corrosion and blockages in equipment and pipelines. Failure to remove these impurities reduces the service life of equipment and pipelines, increases maintenance costs, and presents limitations. Therefore, we propose a gas collection device for petroleum cracking processing to solve these problems. Utility Model Content
