2021年化工设计竞赛国一
    英文回答：
    The 2021 AIChE National Undergraduate Process Design Competition challenged students to design a process for the production of ethylene glycol from natural gas. The process is to be designed to be economically competitive with current commercial processes while also meeting sustainability goals.
    The team's proposed process consists of the following steps:
    1. Syngas Production: Natural gas is reacted with steam in a steam reformer to produce syngas, a mixture of hydrogen and carbon monoxide.
    2. Syngas Cleaning: The syngas is cleaned to remove impurities, such as sulfur and carbon dioxide.
    3. Ethylene Production: The syngas is reacted with ethylene catalyst to produce ethylene.
    4. Ethylene Oxide Production: The ethylene is reacted with oxygen to produce ethylene oxide.
    5. Ethylene Glycol Production: The ethylene oxide is hydrated to produce ethylene glycol.
    The team's process is economically competitive with current commercial processes. The team estimated that the capital cost of the plant would be approximately $1 billion and the operating cost would be approximately $0.5 billion per year. The team also estimated that the plant would produce approximately 1 million tons of ethylene glycol per year.
    The team's process also meets sustainability goals. The process uses natural gas as a feedstock, which is a relatively clean-burning fuel. The process also produces very little waste. The only waste products are water and carbon dioxide.

    2021年全国大学生化工设计竞赛要求学生设计一个利用天然气生产乙二醇的工艺。该工艺的设计应在经济上与当前的商业工艺具有竞争力，同时还应符合可持续发展目标。
    团队提出的流程包括以下步骤：
    1. 合成气生产， 天然气在蒸汽重整器中与蒸汽反应生成合成气，即氢气和一氧化碳的混合物。

    2. 合成气净化， 合成气被净化以去除杂质，例如硫和二氧化碳。
    3. 乙烯生产， 合成气与乙烯催化剂反应生成乙烯。
    4. 环氧乙烷生产， 乙烯与氧气反应生成环氧乙烷。
    5. 乙二醇生产， 环氧乙烷水合生成乙二醇。
    团队的工艺在经济上与当前的商业工艺具有竞争力。团队估计该厂的资本成本约为 10 亿美元，年运营成本约为 5 亿美元。该团队还估计，该工厂每年将生产约 100 万吨乙二醇。
    团队的工艺也符合可持续发展目标。该工艺使用天然气作为原料，这是一种相对清洁燃烧的燃料。该工艺产生的废物也很少。唯一的废物是水和二氧化碳。
