這幾句要怎麼翻譯才順呢?

1. The PURASPEC vessels should be depressurised at a rate that ensures that the bed
does not fluidise and is not damaged. In any event, the rate should not exceed
10 bar/minute above 10 barg or 1 bar/minute below 10 barg.

2. It is recommended that the system is pressurised at rates of not greater than 1 bar
per minute below 10 barg and 10 bar per minute above 10 barg.
This is normally achieved by the use of small bypass valves.

3. The vessels should be purged with nitrogen until the purge gas is free of
hydrocarbon. A heated nitrogen stream may allow the purging to be completed over
a smaller time period. This should begin at the earliest stage that the shutdown
procedure allows and will enable any hydrocarbons, which may be adsorbed onto the
PURASPEC material to vent off. During this period the operator will regularly monitor
the vessel for signs of hydrocarbons in the purge stream.

PURASPEC 容器应该以某个速度减压， 这个速度确保床体在任何情况下不流动，也不被损坏。 在任何情况这个速度在容器压力大于10bar的时候超过 10bar/min 或者在压力低于10bar时候超过1bar/min

per minute below 10 barg and 10 bar per minute above 10 barg.

建议在加压的时候在系统压力高于10bar时候加压速度低于10bar/min， 在系统压力低于10 bar的时候加压速度不超过1bar/min, 这些可以通过小的旁路阀来达到要求。

容器应该用氮气来吹扫一直到氮气里面不含有碳氢化合物。 加热过的氮气可以在很短的时间里面完成这个任务。这项工作应该在最早的阶段进行， 在这个时期执行停车的步骤允许任何附着在puraspect材料上的碳氢化合物吹扫出去。 在这个吹扫阶段， 擦作人员应该定期观测吹扫尾气总的碳氢化合物的痕迹。

fluidise是“流动”还是“流化”，这是个问题。
