Study on Numerical Simulation of Gas Explosion inside Compression Compartment of Gas Filling Station
Authors: Wang Yu , Wu Yun Yi
Published: June 2014

For the compression compartment safety design in gas filling station, hazards of gas explosion inside compression compartment should be assessed, and explosion energy as well as influence factors should be determined. In this paper, numerical simulation was adopted to build 3D model of compression compartment and simulate gas explosion pressure and flame propagation behavior under different ignition point location, open-pressure and weight of relief panels. The results show that the ignition point location relative to the location of the vent opening and relief panel’s characteristics is very important for gas explosion inside compression compartment. The nearer the ignition point location is away from the venting opening location, the smaller the caused explosion pressure will be. For the relief panel, explosion pressure is proportional with the open-pressure and the weight of relief panel. Besides the rational distribution of ignition source and the adoption of relief panel with less unit weight and relief pressure, the crushing material damage and secondary hazard of flame should also be noticed in order to mitigate the hazard of gas explosion.

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.

Published: June 2014

GC and GM-MS experiments are exerted for 34 oil samples in shallow water area of Liaohe Depression. The results show that Gas chromatograms are clear, continuous and intact which means the bio-degradation can be ignored. Originally the sediments are mainly deposited under oxidization environment. The oil resource is composed by the bacteria, aquatic organisms and higher plans. The depositional environment changes from reductive type to oxidization in the W-E direction. The salt content is high. From Lingnan well area in the west to Kuihua well area in the east the oil maturity increases. According to the depositional environment, source rocks and maturity features the oil samples are divided into 3 types. A is located in the west and centre of study area and Gammacerane index is less than 0.2. B in the centre and east. A and B are different in the organic import degree. To be specific the A is mainly supported by aquatic organisms while the B by continental materials. C has high gammacerane of more than 0.55, which comes from salt water environment.

Geogas geochemistry method is a way to predict concealed ores by collecting and testing metallogenic elements and associated elements in rising underground gases, which is very promising for broad applications. Due to the unawareness of the source of abnormal materials, the validity of the method is consistently under suspicion. By purifying the collector, controlling operating environment, improving the sampling device and sampling methods, the contents of interference elements are greatly reduced in this paper. Through the analyses of captured samples, obtaining of the geochemical characteristics of elements, areas for detailed investigation can be delineated. This study proves the validity of this method and provides basis for further prospecting.
