Last month, the complete engineering technology development project passed the technical appraisal organized by the Sinopec Science and Technology Development Department. Experts believe that the complete set of technology has reached the international advanced level and can be industrialized and applied. This set of techniques is equally applicable to other types of atmospheric and vacuum units.
In the development of this complete set of technologies, a number of new technologies have been developed and a number of new technologies have been integrated to form large-scale lubricating oils including large vacuum systems, vacuum fractionation systems, oil transfer lines and heating furnaces. Pressure complete engineering technology, including the development and research of large-scale steam-mechanical combined vacuum system engineering technology, the establishment and experimental research of cold state simulation device for super large liquid distributor, and the research and application of large-scale key piping systems, all of which are domestic innovative technologies. And applied for the first time.
The lubricating oil type large-scale crude oil distillation unit has more characteristics and is more difficult than the fuel type unit. The distillation of vacuum oil to produce lubricating oil distillate is far more complicated and difficult than the production of cracking raw materials, and has high technical requirements. Most of its engineering techniques can be used in fuel-type vacuum distillation systems.
China's largest single-capacity lubricating oil type atmospheric and vacuum unit came out
Developed by Sinopec Engineering Construction Company, Gaoqiao Branch, Tianjin University and Shenzhen Chengda Technology Co., Ltd., China's current single-capacity lubricant-type atmospheric and vacuum unit – Sinopec Gaoqiao Branch 8 million tons The annual large-scale atmospheric and vacuum distillation unit of the lubricating oil type has recently completed a complete start-stop cycle for three years of operation. After the assessment and calibration, the processing capacity, product yield, product quality, and energy consumption of the device all achieved the expected goals.
