摘要
鄯善 30× 10 4m3 /d轻烃回收装置是由加拿大THERMODESIGNENGINEERING公司设计制造的一套装置 ,也是吐哈油田建设的第一套轻烃回收装置。 1992年建成投运以来 ,原始设计制冷系统 (丙烷冷凝的干式空冷器 )不能适应鄯善夏季的气候条件 ,冷却能力达不到工艺要求。为了彻底改变上述状况 ,用一台表面蒸发式空冷器代替原来的干式空冷器 ,拆除原有的列管式换热器和凉水塔等水循环系统 ,进行了丙烷后冷工艺流程改造。运行证明 ,在夏季时 ,改进后的轻烃回收装置的制冷系统一直满负荷运行 ,而且制冷系统满负荷运行时的丙烷冷凝温度要低于制冷系统要求的最高的冷凝温度。可见表面蒸发式空冷器在高温干旱炎热地区具有非常好的适应性 ,由此证明表面蒸发式空冷器是一种结构紧凑、操作灵活、冷却效果好、节能、适应性强 (受环境温度影响小 )的冷却冷凝设备 ,可广泛用于对温度不太高介质的冷凝冷却。
Shanshan 30 × 104 m3/d of light hydrocarbon recovery device was designed and manufactured by a Canadian company named Thermo Design Engineering, also is the first one set up in Tuha oil field. Since putting into operation in 1992, the refrigerating capacity can't reach the process requirements because the original designed system (the dry air cooler with propane cooling) can't adapt Shanshan weather conditions in summer. To solve the problem, the dry air cooler is replaced by the surface evaporative air cooler. The water cycle system with in-line heat exchanger and cooling tower is removed. And the flow-sheet rehabilitation with the propane after-cooling technique is conducted. Operation demonstrates that the modified cooling system of the light hydrocarbon recovery device runs with full load in summer, and the propane condensing temperature under the full load is lower than the highest condensing temperature required by the cooling system. It appears that the surface evaporative air cooler has excellent adaptability in high temperature and dry areas. The surface evaporative air cooler is a condensing device with compact configuration, flexible operation, good cooling effect, energy-saving and excellent adaptability (little influence by ambient temperature), and can be used for condensation cooling of low temperature media.
