Hello Everyone,
We are looking to take natural gas from two suppliers, but the pressure needs to be reduced to our required pressure of 300 psig. Both suppliers have their own letdown stations and then it ties into one pipeline that feeds the factory. See attached sketch of the proposed piping. I am looking for some thoughts on the following.
1. Would we be able to take natural gas from both suppliers at the same time? Is there a possibly for the two pressure reducing valves to fight?
2. Can the two reducing valves operate at the same time? Would there be a possibility for one of the valves slamming shut if the pressure changes on the other let down station?
3. There are flow meters on the lines, but they are not used for flow control. Should we consider the use of a flow controller on one of the reducing stations?
Any thoughts would be greatful.
Thanks,
