Abstract：Based on the technological characteristic of cryogenic method for preparation of LNG with low-concentration oxygen-containing coal-bed methane,this paper discussed the importance of dewatering link in the preparation process of LNG with low-concentration oxygen-containing coal-bed methane and the principle of absorption dewatering,analyzed the selection of technical solutions for dewatering,the determination of the number of adsorption towers in the dewatering unit,the application of loading ways for the dewatering adsorbent and the drawing-up of the regenerative heating system. All of these can provide a certain reference for the development of the dewatering unit of LNG preparation with low-concentration oxygen-containing coal-bed methane.
