According to the China Petroleum Daily, Donghuai Refinery Huludao Design Institute recently received a letter of congratulation from Sinopec Tianjin Petrochemical Corporation, congratulating them for the design of the waste heat recovery heating system designed for Tianjin Petrochemical to fully meet the design requirements and become the company New highlights of energy-saving emission reduction. Tianjin Petrochemical waste heat utilization heating project is China's Sinopec in 2009 reported to the National Development and Reform Commission's key energy-saving emission reduction projects. Mainly on the two thermal power plant condensate pumping unit low-vacuum transformation, the original emissions to the atmosphere of the condensation heat used to heat the living area, in order to achieve the purpose of saving heating steam. After receiving the project commissioned, Huludao Design Institute composed of the project team to the scene several times, through the selection, optimization and coordination, to overcome the scene complex environment, equipment connection difficulties and other factors, to determine the scientific pipeline network. In order to achieve maximum energy-saving emission reduction, Huludao Design Institute designers worked hard to and from Huludao and Tianjin, constantly optimize the design, design changes every time a program, designers will recalculate, demonstrate once. In the design process, designers of Huludao Design Institute not only devoted their time to solving technical problems, but also wanted to minimize their investment in equipment. At the outlet of circulating pump, they applied the multifunctional pump control valve integrated with three kinds of equipment including electric valve, check valve and water hammer eliminator, which not only satisfied the requirements of automatic control system but also effectively reduced the cost. Due to the complex construction conditions, Huludao Design Institute pays special attention to engineering short-range technical support. They sent design technicians with complete skills and strong sense of responsibility to carry out on-site technical services. The design representatives and Party A's technicians and operation staffs live and eat together at the scene and worked day and night to effectively ensure the smooth progress of project construction. Today, according to personnel from Tianjin Petrochemical Industry Co., Ltd., the upgraded heating system has been operating smoothly for 30 days and the heating area has reached 1.6 million square meters. The energy saving effect is very good.
