求翻译：介绍了水溶液全循环尿素工艺中的尿素高压圈技术、预分离-预蒸馏工艺、一吸塔增设外冷器等节能技术。是什么意思？

Describes the full cycle of solution of urea in the urea process technology, high-pressure ring, pre-separation - pre-distillation process, an additional external cooler absorption tower and other energy technologies.

Urea technology introduced the aqueous solution in the entire cycle of urea high pressure area - Pre-distillation technology, pre-separation processes, a drug tap additional cold outside server, saving energy technology.

As soon as outside introduced in the water-soluble fluid complete alternation urea craft urea high clamping ring technology, the predissociation - pre-distillation craft, has attracted the tower to additionally build energy conservation technologies and so on Leng Qi.

Introduced the urea high pressure in water solution total recycle urea process technology, pre-pre-distillation separation process, suck Tower addition of outer cooler and other energy-saving technologies.
