On December 3, Changling Refinery used organic Langcun cycle technology to formally start the grid-connected operation of the first industrial plant that uses the low temperature waste heat of the main refinery project, marking that the production energy management of the enterprise shifted from saving optimization to comprehensive development and utilization.
Low-temperature waste heat mainly includes residual heat resources with a temperature of 90-150 degrees Celsius, including hot water, flue gas, low-pressure steam emission, process heat to be cooled, etc. To tap the potential for energy saving in depth, in 2014, Engineering power generation technology development 'included in science and technology development projects and' energy efficiency doubled project 'project development, Changling Refinery organization of science and technology personnel and related professional R & D, design agency docking project, start the project research, multi-purpose reduction' cooling cooling 'waste heat waste.
The face of a large number of low-temperature production plant temperature and temperature, the status of dispersed technology, in accordance with the 'easy first and then difficult' principle, Changling refinery in the new 1 million tons diesel hydroconversion project to join the low temperature waste heat utilization process and gradually solve the 800 Tons of old and new production system of low total heat, the problem of optimizing the use of hard.
During the process of project construction, scientific and technical personnel and professional design institutes repeatedly demonstrated the technical scheme and fully considered the characteristics of 1 million tons of diesel oil hydrogenation and low temperature residual heat and heat, as well as the overall operation requirements of the plant. It determined that organic Rankine cycle low temperature power generation technology, design and construction Associated power plant.
The project design total generating capacity of 600 kilowatts / hour, the continuous upgrading of oil quality, product oil production process longer, under the pressure of increased operating costs, significantly reduce production energy consumption and enhance the development potential of enterprises and market competitiveness.
