| 5. | The liquid drawn off from the bottom of the first fractionating column , the primary fractionating column , is fractionated again in another column under low pressure 从第一个分馏塔即初分塔底部下来的液体,再在低压下进入其余的分馏塔分馏。 |
| 6. | A typical continuous fractionating column equipped with the necessary auxiliaries and containing rectifying and stripping sections is shown in fig . 21 . 7 图21 . 7所示的是一个典型的连续操作精馏塔。它配备有必要的辅助设施,包括精馏段与提馏段两部分。 |
