本文的目的是评估从甲烷制氢，作为氨输送，并结合CO2利用的能源，碳排放和经济分析。评估采用了CO2利用的常见替代方案，即提高石油采收率，即利用捕获的CO2提取原油。在白杨plus软件中模拟了合成氨生产的物料平衡和能量平衡。利用文献资料，基于简化模型对三次采油开采的原油和CO2排放进行了评价。结果表明，与常规采油相比，采用碳捕集和提高采收率技术的制氢过程中CO2排放总量可减少54.8%，从97.4 t·h-1减少到44 t·h-1。此外，通过使用液氨作为运输载体，氢的成本显著降低。考虑到CO2的销售收入从0到50 $·t-1，当天然气价格为10 $·MMBTU-1和2 $·MMBTU-1时，H2的成本可以分别降低9.52%和14.63%。这表明，销售CO2的收入是一个机会，以减少碳排放，这可能会加速氢技术结合碳捕获和利用在行业中。
The paper aims to evaluate the hydrogen production from methane, transported as ammonia, and integrated with CO2utilisation in terms of energy, carbon emission and economic analysis. The common alternative for CO2utilisation i.e. enhanced oil recovery is adopted for the assessment, which extracts crude oil using captured CO2. Mass and energy balance of ammonia production are simulated in Aspen plus. Oil extracted by enhanced oil recovery and CO2emitted are evaluated based on simplified model using information provided in the literature. Results show that total CO2emission in hydrogen production with carbon capture and enhanced oil recovery could be reduced by 54.8% when compared with conventional oil production, which is from 97.4 tonne·h−1to 44 tonne·h−1. In addition, the cost of hydrogen is significantly reduced by using liquid ammonia as a carrier for transportation. Considering the revenue by selling CO2from 0 to 50 $·tonne−1, the cost of H2could be reduced by 9.52% and 14.63% when gas prices are 10 $·MMBTU−1and 2 $·MMBTU−1, respectively. It is demonstrated that the revenue for selling CO2is an opportunity to reduce carbon emission which could accelerate hydrogen technology incorporated with carbon capture and utilisation in the industry.
