Depressuring in HYSYS refers to the process of reducing the pressure of a vessel or pipeline by releasing fluids, such as gas or liquid, to a lower-pressure system. This process is commonly used in various industries, including oil and gas, chemical processing, and power generation. The Depressuring Utility in HYSYS allows users to model and simulate this process, predicting the behavior of the system under various operating conditions.
