开发了一种从天然气联产乙酸和氢气/电力且二氧化碳排放为零的工艺装置流程图。探讨了两种情况：乙酸和氢气的生产（情况1）和乙酸和电力的生产（情况2）。这通过选择适当的反应簇来实现，其总和导致联产乙酸和氢气/电力的总反应。能量自给的概念被引入，它施加的限制，定义在氧气进料的乙酸生产的比例方面的系统。融合流程图的热电集成揭示了每种情况下的操作范围，确保能源自给自足。选择操作点进行初步的经济分析和二氧化碳成本和性能指标计算，以量化整个过程的盈利能力和碳捕集潜力。(C)2017年美国化学工程师学会
A process plant flow sheet that coproduces acetic acid and hydrogen/power from natural gas with zero carbon dioxide emissions is developed. Two cases are explored: the production of acetic acid and hydrogen (Case 1) and the production of acetic acid and power (Case 2). This is realized by the selection of an appropriate reaction cluster whose sum results in the overall reaction that coproduces acetic acid and hydrogen/power. The concept of energetic self-sufficiency is introduced and it imposes constraints on the system defined in terms of the ratio of oxygen feed to acetic acid produced. Heat and power integration of the converged flow sheet reveals an operating range for each case that guarantees energetic self-sufficiency. Operating points are chosen to conduct a preliminary economic analysis and a carbon dioxide cost and performance metric calculation to quantify profitability and carbon capture potential of the overall process.
