YL天然气处理厂1#甲醇精馏装置自建成投产以来,处理量呈逐年下降趋势,多次优化操作参数均不能达到预期效果,并且经常出现精馏塔塔板结垢堵塞,管线刺漏现象,影响了甲醇回收回收装置的处理效率和处理能力。针对这些问题,我们从装置设备入手,通过对精馏塔等设备的结构设计进行核算,现场取样化验,从而找到装置处理量不足的原因,通过,找到了装置腐蚀的原因,同时提出了优化建议。
YL natural gas processing plant 1 # methanol distillation unit has been put into operation since the beginning, the handling capacity showed a downward trend year after year, many times to optimize the operating parameters can not achieve the desired results, and often flotation trays tower fouling, pipeline leakage, Affecting the methanol recovery and recovery device processing efficiency and processing power. In response to these problems, we start with the equipment and equipment, through the structural design of the distillation tower and other equipment accounting, on-site sampling and testing to find the reasons for the lack of capacity of the device, found that the cause of corrosion of the device, and made recommendations for optimization .
