Comprehensive Computational Analysis Exploring the Formation of Caprolactam-Based Deep Eutectic Solvents and Their Applications in Natural Gas Desulfurization

Pressure monitoring is an important means to reflect the running status of the natural gas desulphurization process. By using the data mining technology, the interaction relationships between the pressure and other monitoring parameters are analyzed in this paper. A pressure trend prediction model is established to show the pressure status in the natural gas desulfurization process. Firstly, the theory of Principal Component Analysis (PCA) is used to reduce the dimensions of measured data from traditional Supervisory Control and Data Acquisition (SCADA) system. Secondly the principal components are taken as input data into the pressure trend prediction model based on multiple regression theory of Support Vector Regression (SVR). Finally the accuracy and the generalization ability of the model are tested by the measured data obtained from SCADA system. Compared with other prediction models, pressure trend prediction model based on PCA and SVR gets smaller MSE and higher correlation. The pressure trend prediction model gets better generalization ability and stronger robustness, and is an effective complement to SCADA system in the natural gas desulphurization process.

Natural Gas Desulfurization

Abstract Based on the latest developments of desulfurization and decarbonization technologies of acidic natural gas, the process characteristics, product purity, consumptions, occupied area, advantages and disadvantages of various desulfurization and decarbonization methods are analyzed and compared, and the adaptability of the methods on offshore platform is fully considered. According to the actual situation of a Bohai offshore gas field, the low temperature separation method is adopted and the desulfurization and decarbonization process is simulated by using HYSYS software, and then the technical scheme is put forward to meet the requirements of the gas turbines on surrounding platforms and the transportation quality index of the southwest Bohai gas supply pipeline network. This research has a certain reference value for technical programs of natural gas desulfurization and decarbonization on similar offshore projects.
