Abstract

The article examines and analyzs patents, published scientific works, and currently used scientific and practical methods and devices for regulating the parameters of the low-temperature separation process in production. However, the conducted analysis showed that one of the main causes of hydrate formation in the device is the lack of continuous comprehensive control over parameters such as the pressure of the inhibitors supplied to the injectors at each stage and the moisture content of the total gas, i.e., the moisture content of the total gas at the system inlet, the gas temperature at the device outlet, and the pressure and consumption of the inhibitor supplied to the inlet of the low-temperature separation device. In this regard, the aforementioned problems - namely, optimizing the consumption of inhibitors during the low-temperature gas separation process, taking into account the gas temperature at the device outlet, continuous monitoring of gas pressure and temperature at the system outlet, and the creation and implementation of an intellectualized system for monitoring the overall and individual device consumption of the inhibitor, as well as the optimal maintenance of gas pressure and temperature at the system outlet, taking into account external disturbances affecting the temperature and pressure of the main system parameters are considered topical issues. The proposed intellectualized system allows for the optimization of inhibitor consumption and maintains the low-temperature separation process within the limits specified in the regulatory documents.
