- 摘要：
- Hydrogen is a crucial and expensive resource
for refineries. Hydrogen network integration is an effective way
to conserve fresh hydrogen. On the basis of relative
concentration analysis, a mixed integer linear programming
(MILP) mathematical model is established to synthesize
refinery multi-impurity hydrogen networks. By correlating the
hydrogen consumption of a sink with its oil processing
throughputs, this model reveals the fresh hydrogen variation
tendency caused by fluctuation of each capacity, and
determines the key sink(s) of a hydrogen network with
multiple impurities on the premise of minimum fresh
hydrogen consumption. With a structure matrix variable,
practical hydrogen networks can be analyzed through the
proposed model. The results show that the novel method in this paper is superior to traditional absolute concentration-based
methods in fresh hydrogen conservation under cases of static, fluctuant throughputs, and fluctuant throughputs with restricted
network structure. Two cases are employed to demonstrate its application.
