双语例句
- When light C4 hydrocarbons are used as feedstocks for MTBE but not for alkylation unit, cancelling the C4 tower from the flow diagram of a grass-roots light ends plant or shuting it down in an existing unit is necessary for investment and energy savings.
当气体分馏装置的轻C4组分只作MTBE原料不作烷基化装置的原料时，气体分馏装置不设或不开碳四塔是必要的，这样可节约投资和能耗。
