2014年度靖二联轻烃厂QC成果论文1 With the practical application of the new technology in the field, it is agreed that the process of the cooling equipment of oil stabilizer is agreed. Feasibility analysis Exports to field region extraction of crude oil cooler technology renovation, transform the cooler process pipeline, pipeline outside the station presets, namely the circulating water from the shell side of the original process to monitor, process medium by the shell side of the tube side instead of the original process, at the same time because of the smoke gas cooler shell side of the original export container ontology docking port diameter is 6. The pipe size of the heat exchanger is DN150, and the water pipe diameter is DN80. Finally, clean the air outlet cooler core and replace the cooler head cushion. After the renovation, the design of the site can be met. Reason analysis 1, because the two screw extraction pressure machine exhaust temperature, energy consumption of equipment, heat exchanger effect difference to downstream of the original three phase separator, entrance separator separation and C3 + recovery effect. Oil stable coolers due to long outage, which cause corrosion and fouling of the tubes. Its bad to change the heat after delivery. Six, because of verification The main reasons for the analysis are as follows: Refrigerating conditions As summer temperatures continue to rise, the cooling circulatory system can reduce the cooling effect by producing scale (calcium carbonate and magnesium hydroxide) at high temperatures. The design process is not in line with the actual design The oil stable cooler is designed for cooling water, which can cause the dirty plug to cause the change of heat efficiency. Implement measures The serial number Due to the grain goals right Measures to head 1 The design factors Ensure that the modified process parameters are reasonable and meet the requirements of the production process We will formulate a plan for the improvement of the o
