Development of a mobile intellectual device for a mobile analyzer of natural gas concentration

As a clean energy, natural gas accounts for an increasing proportion of my country's energy consumption structure. Due to the flammable and explosive characteristics of natural gas, natural gas leakage can easily cause safety accidents. This paper has designed a gas concentration detection system based on the principle of infrared absorption, which can detect the methane concentration in natural gas, quickly determine whether there is a methane leak, and effectively protect people's lives and property.

Excellent Description

A mathematical model for predicting the permeability of natural gas in polymer nanocomposites was developed and tested using experimental data. The model takes into account the effects of pressure, temperature, crystallinity and nanoparticle loading. Three model parameters (, and) were obtained. The parameter is a measure of the activation energy, described the effect of nanocomposite loading, and can be used to describe the effect of gas concentration on the. Polymer nanocomposites were prepared using high density polyethylene as polymer matrix and Cloisite 15A as nanoclay. The proposed model was used to predict the permeability of the nanocomposites to pure CH4 and mixed CH4/CO2 gases (containing 80 mol% CH4) at pressures up to about 106 bar and temperatures between 30 to 70°C. Predicted results show that the developed model provides an excellent description of natural gas permeation in pure HDPE and its nanocomposites.
