Column internals factory inspection - process or mechanical
Column internals factory inspection - process or mechanical
(OP)
Dear All,
i'd like to get some info on this as to what other companys do.
So for new column projects do your process engineers or mechanical handle the factory inspection of the trays ?
Who manages the construction quality checks and plans?
Do you inspect distributors and conduct flow tests? if so do you witness via mechanical or process ?

RE: Column internals factory inspection - process or mechanical
Construction quality inspection/checks usually left to mechanical/inspection people.
If your process allows I would try to get a water test on the tray so you can watch the flow pattern before closing the tower.

Take the process data sheet of your column licensor and see if the critical process dimensions were respect by the column constructor. One important check in a tray is the leveling of the tray. Other checks are water test the accumulator trays to see the acceptable leaking rate. Construction quality checks are also important. In a refinery this work is done by the inspection people.

Is there a problem with bringing a rep from each discipline ?
Additionally, who wrote the design spec ?
Ultimately, it is the author(s) of that spec that must accept the equipment

Within most firms, mechanical engineers buy the equipment including the internals. For another stab at some in the business, many engineers (process, mechanical and others) lack experience at fabricating shops, job sites or operating plants. I am a strong advocate for all engineers to participate in the activities at each of these locations.
In contrast to home office engineers with an E&C firm, operating company process engineers are very involved including witnessing the tray or packing installation.
BTW I am in the instrumentation and control systems business. Outside the control valve area, QA is not as helpful in the I&CS domain.
