摘要
补充氢是渣油加氢装置重要的原料之一,补充氢纯度将直接影响装置投资和操作费用。以典型的260万t/a渣油加氢装置为例,通过流程模拟,分析两种不同补充氢纯度对装置设计的影响,对装置操作费用、设备投资进行了比较。结果表明,使用低纯度的补充氢将导致设备投资和操作费用提高。
Make-up hydrogen is one of the important raw materials for residue hydrogenation unit,and the purity of make-up hydrogen will directly affect the investment and operating costs of the unit.Taking a 2.6 million t/a residue hydrogenation unit as an example,the influence of two different purities of make-up hydrogen on the design of the unit is analyzed through process simulation,and the operating cost and equipment investment of the unit are compared.Studies show that low purity of make-up hydrogen will result in higher equipment investment and operating costs.
