I've already talked with a vendor about the checkall valve and are leaning that way to replace the existing checks (that failed).
Flow is going other places further back in the line and line pressure is controlled by VFD's on the feed pumps, so blockage of flow shouldn't cause critical...
First, thanks for the replies.
Second, we do have swing check valves installed in two places going to the injection point with the solvent. Both failed. It is not possible to have air break at the system as we need to maintain the temperature of the water (220 to 240 F) for optimal process...
Is there any way to protect the inlet of a pressure vessel from backup?
We have hot DI water (240F) used in two places throughout our plant. One section involves a contactor with a solvent and the other is for final purification before crystallization. A week or so ago, the supply pumps for...
Is there any way to protect the supply into a pressure vessel from back up? (Similar to an overflow pipe on an atmospheric tank)
We had an incident a week or so ago where a solvent got into our hot DI water (240 F) system and contaminated our final product. Needless to say, our upper...
