查询词典 natural gas

There is a growing realization that the only effective way to achieve further reductions in vehicle emissions - short of a massive shift away from the private automobile - is to replace conventional diesel fuel and gasoline with cleaner-burning fuels such as compressed natural gas, liquefied petroleum gas, ethanol, or methanol.

这些清洁燃料包括压缩天然气、液化石油气、乙醇和甲醇。

ABSTRACT This thesis emphasizes on theoretical and experimental research of film condensation heat transfer of natural gas and petroleum gas.

It showed that the propane recovery rate of new process would be 23%~27% higher than that of cryogen refrigeration process at the same refrigeration temperature. To increase the absorption tower pressure appropriately was good to improve the propane recovery rate. However, the choice of pressure must take the pressure of the feed natural gas and product gas into account together. The flow rate of absorbent had great effect on propane recovery rate and tower heat load.

本文实例研究表明：相同制冷温度下，冷剂制冷－油吸收复合工艺的丙烷回收率比原冷剂制冷工艺可提高23%~27%适当提高吸收塔的压力，对增大丙烷回收率有利，但吸收塔压力的确定要综合考虑原料气压力和外输气压力的大小。
