提出了一种基于相平衡（PE）分离和甲烷重整的洁净氢气（99.9999%）和干冰生产工艺。通过制定和解决相关热交换网络的最低热/冷/电公用事业成本问题，对拟议的过程进行了热电一体化研究。如果生产的干冰以2美分/干冰- 1的价格出售，或者如果承认等量的二氧化碳封存信用额度，那么该工艺的最佳运行成本将低于传统的变压吸附法的相应成本。
A clean hydrogen (99.9999%) and dry ice production process is proposed, which is based on phase equilibrium (PE) separation and methane reforming. Heat and power integration studies are carried out for the proposed process, by formulating and solving the minimum hot/cold/electric utility cost problem for the associated heat exchange network. The optimum operating cost of the proposed process is shown to be lower than the corresponding cost of the conventional PSA (pressure swing adsorption) based process, if the produced dry ice is sold for as low as 2centskg-dry-ice−1or if an equivalent CO2sequestration credit is conceded.
