摘要:
介绍了以大豆油为原料的，用超临界酯交换方法生产生物柴油的三种不同工艺.在醇油比40∶1，大豆油转化率95%，酯交换反应温度300 ℃，反应压力15 MPa 的条件下，对10 000 t/a生产线进行了热量衡算与经济评价，将三种不同工艺(无闪蒸、冷却后闪蒸和不冷却直接闪蒸)进行了比较.在超临界甲醇法连续制备生物柴油时，与未引进闪蒸装置及不冷却直接闪蒸的工艺相比，采用冷却后闪蒸的工艺能耗最少，闪蒸装置甲醇回收率为88.7%，生产10 000 t生物柴油可节约10.7%的能量，此工艺在购置设备方面较其他两种工艺费用高，但综合成本仍是最低的.
Abstract:
Three different production processes of biodiesel via supercritical transesteri?cation from soybean oil were introduced. While the methanol oil molar ratio was 40∶1，biodiesel yield was 95%，transesterification reaction temperature was 300 ℃, and reaction pressure was 15 MPa，a heat balance and economic evaluation of 10 000 t/a plant processes for biodiesel has been studied for three different processes（process without flash device，flash process after product cooling and flash process without precooling）. For supercritical transesteri? cation processes for biodiesel continuous production from methanol，compared with the processes without flash device or with flash process without precooling，the flash process after product cooling had the lowest energy consumption，with a 88.7% methanol recovery rate for the flash device. Despite this process had the highest cost with the greatest number of equipment pieces than the other two processes，its overall costs was still the lowest.
