Shanghai Petrochemical Residue Hydrogenation Plant Low Gas Distribution Drying System
On October 10, the new low-gas drying system of Shanghai Petrochemical's 3.9-million-ton/year residual oil hydrogenation plant was put into operation after three months of on-site construction and production preparation.
The system consists of 2 dryers, 1 pre-dryer, 2 water separators, 1 heater and 1 cooler, etc. It consists of 7 devices, which are used for drying and dehydration of the low gas sent from the residue hydrotreating unit. Therefore, the water content in the low gas separation can be reduced to less than 300 ppm, which effectively reduces the impact on the adsorbent of the downstream device due to the high content of low gas separation water, and ensures the safe long-term delivery of the low gas separation.
At present, the system is running well and all the indicators have reached the design value. The operating conditions of the low-gas separation pipe and the raw material properties of the downstream devices have all been significantly improved.
2 post car lift is a new generation of product with new design. The whole is made of high-strength aluminum profiles. Due to the high strength of the profiles, the deflection and swing of the elevator are extremely small. Double mast column structure is adopted, with large load capacity, large platform area, excellent stability, flexible operation and convenient implementation. Its lightweight appearance can give full play to the highest lifting capacity in a small space. The elevator is widely used in factories, hotels, buildings, shopping malls, stations, airports, stadiums, etc. It can be used for installation and maintenance of power lines, lighting appliances, overhead pipelines, and high-altitude cleaning.
The free lifting feature of two post car lift has been widely used in municipal maintenance, cargo transportation of wharf and logistics center, building decoration, etc. the car chassis, battery car chassis, etc. can walk freely, and the working height and space are also changed. It has the advantages of light weight, self walking, electric starting, self supporting, simple operation, large working surface, and 360 degree free rotation, especially the ability to cross obstacles for high-altitude operation.
The lifting height of two post car lift varies from 4m to 18m. The load of this series of products is divided into 0.1 to 0.8 tons, and can also be customized according to the requirements of users. The maximum load can reach 10 tons. The equipment that can be used for vertical transportation in logistics systems such as factories or automatic warehouses. The elevators are often equipped with various plane transportation equipment as connecting devices for transportation lines of different heights.
