摘要
基于中原油田天然气处理厂生产纯度为99.5%异丁烷产品装置的实际操作情况,建立新的工艺模型,并模拟计算出生产纯度为99.9%异丁烷的工艺参数。在实际操作中,优化生产过程和工艺参数,对加热炉和差压调节系统进行更新升级,确保能够精确、平稳控制生产过程,使异丁烷塔进料中n-C4纯度由原来的小于0.3%降低为小于0.085%,丁烷塔回流量增大到20m3/h以上,两塔温度控制在很小的波动范围内,最终生产出纯度大于99.9%的高纯异丁烷产品。
Based on the operation of 99.5% purity iso-butane production, a new process model was set up to calculate the process parameters for producing 99.9% purity iso-butane. Optimization of process parameters and production process was carried out. By updating the furnace and pressure-difference regulation system, the control of production process was more accurate and stable. Therefore, the n-butane content in the feed of iso-butane tower could be reduced to less than 0.085% from the original of less than 0.3%; the back flow of butane tower was increased to 20 m3/h; the temperature of both towers was controlled stably. Eventually the more than 99.9% high purity iso-butane product was obtained.
