From the raw material holding tanks, product is now sent to the blending area of the plant. Again, the PDP allows for total recovery of the product remaining in the line after the measured amount has been sent to the blending tank. Note that pigging could be reversed for this operation (e.g. pushing from the blending tank to the holding tank and back), depending on custom applications and requirements. The Process Pigging System is very adaptable and can be suited to any and all application types.
