本工作探讨了通过费托合成将石油焦（石油焦）和天然气转化为液体燃料的技术可行性和经济效益。对不同的石油焦转化策略进行了研究，以确定与当前市场价格相比具有竞争力的转化途径，而对环境的不利影响很小或没有。三个主要的设计方法被认为是：石油焦气化，结合石油焦气化和天然气重整通过传统的工艺步骤，和结合石油焦气化和天然气重整直接集成气化炉的辐射冷却器与气体重整器。调查的设计包括有和没有碳捕获和封存的情景，以及有和没有CO2排放税惩罚的情景。所考虑的绩效指标包括净现值、生命周期温室气体排放和避免的二氧化碳成本。将天然气重整与气化步骤直接集成的设计配置显示出对于所进行的广泛分析而言是更有前途的设计。白杨Plus模拟文件已免费提供给公众。(C)2018爱思唯尔有限公司版权所有
This work explores the technical feasibility and economic profitability of converting petroleum coke (petcoke) and natural gas to liquid fuels via Fischer-Tropsch synthesis. Different petcoke conversion strategies were examined to determine the conversion pathway which can be competitive with current market prices with little or no adverse environmental impacts. Three main design approaches were considered: petcoke gasification only, combined petcoke gasification and natural gas reforming through traditional processing steps, and combined petcoke gasification and natural gas reforming by directly integrating the gasifier's radiant cooler with the gas reformer. The designs investigated included scenarios with and without carbon capture and sequestration, and with and without CO2 emission tax penalties. The performance metrics considered included net present value, life cycle greenhouse gas emissions, and the cost of CO2 avoided. The design configuration that integrated natural gas reforming with the gasification step directly showed to be the more promising design for the wide range of analyses performed.
