Abstract

The article provides a description and comparative analysis of the original integrated technology for using natural gas with the simultaneous production of energy and synthetic liquid motor fuel and the partial sequestration of carbon dioxide. The installation operates in two main modes: it generates electricity, heat, and methanol during daylight hours. During night hours of the electric load, CO₂ is partially extracted from the flue gases using the mastered industrial technology, which is converted in a plasmatron with the addition of natural gas and water vapor into synthesis gas, which is significantly richer in hydrogen and carbon monoxide than daytime gas. The resulting additional synthesis gas is sent to a methanol synthesis catalytic reactor, in which, thanks to the use of richer synthesis gas, the methanol synthesis process is accelerated on existing equipment. At the same time, the energy-generating part of the plant’s equipment operates in almost the same mode, although the supply of useful electricity in accordance with the requirements of the power system is reduced several times. The use of a single-pass methanol synthesis reactor drastically reduces the size and cost of synthesis unit equipment. At the same time, a significant content of unreacted useful gases (H₂ and CO) at the outlet of the synthesis reactor is not a drawback of the scheme since the exhaust gases are used as fuel for an energy gas turbine plant. A feature of the proposed technology is the beneficial use of CO₂ during the night period, which, in addition to a significant reduction in its emissions into the atmosphere at this time, simultaneously and without additional costs, also solves the problems associated with its disposal since carbon dioxide is used inside the technological scheme as a raw material for obtaining additional amounts of synthesis gas. Compared with existing plants for the separate production of electricity, heat, and methanol, the proposed technological scheme will allow achieving natural gas savings of approximately 20% and reduce atmospheric CO₂ emissions by up to 30%.

利用天然气生产电力，热能和合成液体燃料，并将二氧化碳排放部分隔离到大气中的能源技术复合体的概念

摘要

本文对使用天然气，同时生产能源和合成液体汽车燃料以及二氧化碳的部分隔离的原始集成技术进行了描述和比较分析。该设备以两种主要模式运行：在白天，它会产生电能，热量和甲醇。在电力负荷的夜间，CO ₂使用熟练的工业技术从烟气中部分提取烟气，然后在等离子加速器中通过添加天然气和水蒸气将烟气转化为合成气，合成气的合成氢比白天的天然气富含氢气和一氧化碳。将生成的额外合成气送入甲醇合成催化反应器，在该反应器中，由于使用了更丰富的合成气，可以在现有设备上加速甲醇合成过程。同时，尽管根据电力系统的要求减少了有用电力的供应，但工厂设备的发电部分几乎以相同的模式运行。单程甲醇合成反应器的使用大大降低了合成单元设备的尺寸和成本。同时，合成反应器出口处的CO ₂和CO ₂）不是该方案的缺点，因为废气被用作燃气轮机设备的燃料。拟议技术的一个特点是在夜间可以有效利用CO ₂，这不仅可以大大减少此时向大气中的排放，而且同时无需额外费用，也可以解决与处置CO ₂有关的问题。因为在该技术方案内部将二氧化碳用作获取额外数量的合成气的原料。与现有的分别生产电，热和甲醇的工厂相比，拟议的技术方案将使天然气节省约20％，并减少大气中的CO ₂ 排放高达30％。
