基于PSA分离的生物天然气提纯精制技术

Biogas purification to bio-natural gas based on PSA

2017年07月31日作者:来源:治污专家

  以生物质能高效利用为目标,研发了基于变压吸附(PSA)分离的生物天然气提纯精制技术,可以用于污泥、餐厨垃圾等生物质废物厌氧消化产生的沼气以及填埋气等的提纯。采用该技术可以获得甲烷纯度大于97%的生物天然气(BNG),甲烷回收率可以达到95%以上,产品气质量符合国家《车用压缩天然气 (GB18047-2000)》标准。该技术获得2项国家发明专利和两项省部级奖励,并被列入《国家鼓励发展的环境保护技术目录》。目前已在北京、深圳、淄博、丽江等地得到应用。

 

 

 

      Biogas purification to bio nature gas based on PSA technology was developed for the high efficient utilization of bioenergy. The technology can be used to purify landfill gas and biogas from anaerobic digestion of sewage sludge, food waste, and etc. Bio-natural gas (BNG) containing more than 97% methane can be obtained and the recovery rate of methane can reach 95%. The BNG product meets the national quality standard “Compressed natural gas as vehicle fuel (GB18047-2000)”. 2 patents and 2 provincial and ministerial level awards were obtained as achievements. The technology was listed in “Technology Catalogue of Environmental Protection Encouraged by the State”. As well, this technology has been applied in Beijing, Shenzhen, Zibo, Lijiang, and etc.
