简述了哈尔滨石化公司甲乙酮车间仲丁醇(SBA)精制工段的基本工艺流程,针对精醇(SBA)收率偏低的问题,通过建立三元共沸模型,优化主要设备操作,严格过程控制,有效的降低了仲丁醇的损失,在提高精醇(SBA)收率上取得了一定的实效。为了区别起见,姑且称水合工段产品为粗醇(粗SBA),仲丁醇精制工段主产品为精醇(精SBA)。 In this paper, the basic process of SBA refinery in Harbin Petrochemical Company is described. According to the problem of low yield of SBA, through the establishment of ternary azeotropic model, optimizing the operation of main equipment and strict process control , Which effectively reduced the loss of sec-butanol and achieved some results in improving the yield of refined alcohol (SBA). For the sake of distinction, let’s call the hydration section product crude alcohol (crude SBA), sec-butanol refining section main product refined alcohol (refined SBA).
