ABSTRACT:
An automatic shut-down system for wet/dry glycol pump thereby providing a pump protection system located in the fluid circuit between the reboiler and glycol contactor elements of a gas dehydration system. The system includes a filter or filter system, if one is not already provided within the existing dehydration system, a vertical tank having an external gas operated float valve with controls for remotely pilot operating a cut-off valve located in the wet glycol line between the contactor and the glycol pump. Therefore, in operation, when the dry glycol level in the vertical tanks drops below a set level, the float valve blocks gas pressure applied to the cut-off valve maintaining it in the open condition, thus allowing it to close and thereby blocking the flow of wet glycol to the pump, thus effectively shutting down the pump and the system. Once the imbalance is corrected, the system automatically resumes operation.
