- 摘要：
- Hydrogen and water are important resources for refineries. Pinch based conceptual method is an
effective tool for fresh resource conservation of hydrogen and water networks. A novel graphical method
is proposed to identify the minimum consumption of fresh resource and design the network for both
hydrogen and water networks with single contaminant. This method replaces traditional total flow rate
and absolute concentration constraints with hydrogen load and relative concentration, constructing the
composite curves in contaminant load versus hydrogen load diagram to perform the targeting and design
process. Furthermore, the proposed method can be reinforced by integrating purification reuse,
conserving more fresh hydrogen and further reducing the waste discharge. This new method is visible,
simple and easy to understand, suitable to both hydrogen and water networks. Three cases are studied to
illustrate its application.
