Can the distillation system be pressure-tested with steam?
Thread Content
For the initial commissioning, some information regarding the hydrocracking and fractionation system suggests that steam pressure testing can be used. One question is: how to maintain the pressure? Won’t the condensation pressure drop?
If the pressure testing plan permits it, then it’s possible. As long as there is a sufficient supply, a certain pressure can be maintained.
Once steam penetration is completed and the thermal testing of the equipment is finished, the system can undergo steam pressure testing; but it’s obvious that such an operation is extremely difficult to carry out. So, it can be one of those methods, but it’s definitely not a common one.
It’s possible, but the pressure increase is slow; testing can be carried out in stages. Once the temperature of the entire system rises, the pressure will increase more rapidly. In fact, the process of increasing pressure is also a way to identify leaks, and the advantage of using steam for testing is that it makes it easier to locate leaks. . . .
