Testing issues with atmospheric and vacuum distillation roof extractors
Thread Content
A new atmospheric and vacuum distillation unit is being built. It is planned to conduct vacuum extraction tests, as well as individual tests on each vacuum extractor (a total of 6 extractors of level 1, 2, and 3, which will be operated separately to monitor the vacuum level). I wonder if this is feasible; please provide guidance.
It is not feasible to use a vacuum system of levels 1 and 3, as the design requirements for vacuum level can only be met when all stages are at level 3. 2. Driving: First, operate the injector far from the system side to reach 25–30 KPa, then operate the middle injector to reach 8–10 KPa, and finally operate the injector connected to the system. 3. There are 2 sets of injectors, with 3 units in each set ； It is generally 50% load, or 70% load. It can be operated in one set separately, or two sets together.
