Текст про безопасную эксплуатацию испарителей-конденсаторов.

Испарители двух видов:

- Bath-Type Reboilers (испарители в виде ванны?../ ванные испарители? О_О)

[While the liquid level in the reboiler generally increases by reducing the plant load, it can decrease while increasing the load.
According to the speed of the load increase, the sump liquid level and consequently the reboiler recirculation rate can fall very rapidly. The allowable drop of the submergence level in these reboilers shall be provided by the plant designer. ]

и

- Downflow Reboilers (испарители с нисходящим потоком?)

[The recirculation rate shall be maintained as in normal operation. The level in the distributor or the measured liquid flow to the distributor shall not fall below the allowed minimum during any plant load change. During plant load changes, the liquid level in the distributor feeding the downflow reboiler can temporarily fall below the normal operating level. This is acceptable, as long as the steady state level is above the minimum. Note that in many cases, the recirculation flow rate can be used instead of a direct level measurement.]
