Hello house,
Please, i want to know the position of valves on standby PSV.
I know that the downstream manual valve should always be locked open, and if it is a single valve upstream, it should be locked close. But in a situation of double-block upstream what should be the position of each valve...
Thanks L.I., you're hitting the point "out of range" / "invalidity".
That is exactly what our transmitter in the electrostatic dehydrator is doing, because of increase in water-cut production recently, we've being strongly to maintain the interface of the dehydrator, and it goes to out-of-range...
I know that LDTs are to measure difference in level between two liquids.
But, my question is what will be the behaviour of the LDT when it sees only one phase of the liquid?
You've to definitely develop reading habit, because there is always information in a book that you think you don't need, but sometimes you'll need those information.
Hi Smart, it is really unusual, i haven't heard of such and it hasn't happen on our plant.
I don't know if you guys normally take the innage and ullage of your cargo tanks prior to the export, but if not, i will suggest you try this by taking the innage and ullage of the tanks not nominated for...
Thanks all for the replies.
Yes, Zdas04, you're correct, that is what i used to know about it (tri-cock). But, the term came up at my work site when level gauge on site and transmitter to control room becomes inoperative on the electrostatic dehydrator. The only way to know the liquid level is...
Please, i need an explanation to the meaning of a try-cock, if it's just a valve name only or also apply to as a set of valve arrangement for sampling vessel levels when level gauges are in-operative.
Thanks.
