| 摘 要： | 目前大部分天然气是通过高压管道或LNG的方式来输送,这两种方法的初期投资和运营费用都很高。文章提出以天然气水合物(NGH)球的形式来输送天然气,并讨论了船运NGH的流程及其可行性。定性地比较了NGH输运方式与LNG输运方式的经济性。在年天然气输送量为40万吨以下、输送距离为3000海里范围内，NGH船输送方式比LNG输送方式有一定的经济优势。考虑到NGH和LNG生产制造过程和再气化过程的费用，NGH输送方式的经济优势将更为明显。

| Abstract: | Gas transmission is an important part of gas industry. Most of gas is transported by pressure pipelines or LNG now. The two ways have huge initial investment and running cost. The article proposes to transport gas in form of natural gas hydrate ( NGH) pellets. The workflow and the feasibility of shipping NGH are discussed. The economy is compared qualitatively between NGH and LNG transportations. When the transportation capacity is less than 400000 t. /a. and the transportation distance is less than 3.000 nautical miles, the shipping NGH is economically better than the shipping LNG. The economic advantage of shipping NGH will be more obvious considering the difference of producing and re-gasifying costs between NGH and LNG. |
