Tianjin Petrochemical's atmospheric and vacuum unit energy consumption ranked first among similar devices

Tianjin Petrochemical's comprehensive energy consumption of 10 million tons of atmospheric and vacuum units is 7.66 kilograms per ton of standard oil, ranking first among similar equipment in the Sinopec system.

In order to further reduce the processing energy consumption of the plant, Tianjin Petrochemical has broken down the 22 control indicators into 172 and 1625 control points in the detailed process of the whole process of decomposition, and determined the control standards and responsible persons one by one. Daily comparison of various data, find problems affecting the processing energy consumption of the device, and formulate optimization measures. As of the end of May, the workshop has implemented eight cost-reduction measures, including the recycling water consumption dropped to 2.0803 tons / ton, the power consumption dropped to 6396 degrees, "three-dose" fees fell to 960,000 yuan / month. They also adjusted the heat exchange network according to the changes in crude oil, increased the heat exchange final temperature, and also adjusted the operation of the heating furnace to reduce the exhaust gas temperature and fuel consumption. This alone saved 2249 tons of fuel gas.

In order to increase the enthusiasm of the entire staff for energy saving and consumption reduction, they carried out “small index” competitions among workshops and workshops. They included small indicators such as steam consumption per unit of 1.0 megapascals and recycled water consumption in the competition content and conducted monthly evaluations. And make appropriate rewards. Since the start of the activity, the unit steam consumption of 1.0 MPa has been reduced from 0.0153 tons/ton to 0.0115 tons/ton. From January to May, completed more than 20 large-scale optimization projects, such as increasing decompression, deepening wax production, reducing product overlap, increasing production of naphtha and aviation coal, and optimizing operation and energy conservation, and achieved better effect of reducing consumption.

â‘ Hardness:

Due to the scientific synthesis of high-molecular polyurethane elastomer materials using iron rubber, the higher the hardness, the higher the modulus, the smaller the elongation, and the better the wear resistance and heat resistance. Well, in the range of minus 35 degrees Celsius to 100 degrees Celsius, and at a pressure of 60 to 70 MPa, the maximum sealing performance can be guaranteed.

The use of viscoelastic seals made of nitrile rubber is the most complete protection against damage caused by back pressure. In the range of minus 55 degrees Celsius to 100 degrees Celsius, and under a pressure of 21MPa, due to the rubber The seal is often in a compressed state, so the compression performance of the rubber seal must be considered. It not only achieves enhanced anti-climbing performance and low friction resistance, but also has good performance in dealing with special low-temperature oil, and can also be used in combination with Anti-wear Ring double-purpose retaining ring BRL type.

Sealing products made of polytetrafluoroethylene and nitrile rubber/PTFErubber; or seals made of nylon resin and nitrile rubber, which can be used in a wide range of applications with large pressure changes and fast sliding speeds According to the working condition, the input hydraulic pressure cutout is designed on the end face of the polytetrafluoroethylene ring to prevent penetration leakage. The maximum working temperature environment is minus 40 degrees Celsius to 160 degrees Celsius; the maximum working pressure is 50MPa.
