What is ultimately constrained is refinery profitability. When there is insufficient hydrogen quantity or purity then charge rates, the processing of more difficult feeds, or product quality are limited and refinery margins are reduced. When sufficient hydrogen is available then the impact of inefficiencies will be higher operating (hydrogen production) costs. 求中文翻译，谢谢 |
