摘　　要： 目前国内沼气的高效利用技术缺乏,不能满足产业发展需求,开发出简捷实用的工艺流程和方法,可达到沼气低值产品高值利用的目的。为此,依据沼气的基本特性和天然气管网实际需求,研究出了能够适应各种不同工况的沼气利用工艺技术方案,即对沼气实施完全提纯技术和部分提纯技术。针对沼气产地的具体情况,通过技术经济分析比较后,优选了工艺流程,采用最优化工艺技术路线,使沼气经过相应的净化处理后,直接输入天然气管网,或者与其他燃气混配后进入天然气管网;也可以生产出压缩天然气产品外运,或者制取压缩沼气后外运,以实现沼气利用成本最低化、附加值最大化的目标。 For lack of advanced technologies,biogas can not be yet efficiently utilized as an alternative energy source in China.A simple and practical process is necessary to be developed to achieve the purpose of turning the low-value biogas into a high-value fuel gas.Hereby in this paper,according to the basic characteristics of biogas and the actual requirement of pipe gas,a process technical scheme for biogas production is thus developed adaptable for different working conditions.With this process,methane gas can be completely or partly extracted from biogas.In the light of the situation of a biogas generation site,through technological and economic analysis,the technical process is optimized.Then after the corresponding cleaning process,the methane biogas will be obtained to enter the gas pipe network directly or after being mixed with other fuel gases;on the other hand,it will be also produced as the compressed natural gas to be sold out or even the compressed biogas will be produced to be transported outward.As a result,the biogas can be utilized to the highest degree but at the lowest cost.
