Dynamic decompression control for high pressure seals
Abstract:
The present disclosure is directed to a method and system for dynamically controlling seal decompression. The method includes monitoring a set of parameters associated with an operation of a seal, wherein the set of parameters includes a maximum pressure subjected to the seal and an exposure time at the maximum pressure, calculating a target pressure ramp down rate based on at least one of the maximum pressure and the exposure time, and decreasing a pressure about the seal at a decompression rate that is based on the target pressure ramp down rate. The system includes a controller having a memory device, a graphical user interface, at least one pressure transmitter configured to monitor the pressure about the seal, and a processor, wherein the processor is configured to detect a maximum exposure pressure and exposure time at maximum pressure about the seal and control a pressure ramp down about the seal based on the maximum exposure pressure and the exposure time detected in order to prevent explosive decompression of the seal.
