The 4Nm3/d biogas separation and purification project of Yantai Shuangta Food Co., Ltd. undertaken by Kaifeng Yellow River Air Separation Group Co., Ltd. was successfully commissioned and started on December 31st, 212. Product gas index: methane purity > 97% CH4; Carbon dioxide content < ＜1.5%CO2；; Nitrogen content < 1.5% N2; Hydrogen sulfide ≤ 15mg/nm3; All indicators meet the design requirements and meet the relevant national standards.
Kaifeng Huanghe Air Separation Group actively explores the field of new energy products. Since the end of 28, it has started research on biogas purification and purification technology. The self-developed "biological natural gas purification" technology has a series of characteristics, such as advanced process flow, reliable equipment operation, no pollution to the environment, low cost and high efficiency. This technology fills the gap in China and maintains the leading level. So far, it has successfully applied for 9 patents.
Yantai Shuangta Food Company was successfully listed on the main board of Shenzhen Stock Exchange in 21. It is a leading enterprise in the domestic food industry and the largest vermicelli production enterprise, and it is also the first enterprise in the food processing industry to use sewage for biogas upgrading and carry out wastewater recycling. In this project, biogas produced by sewage treatment is used to produce bio-natural gas, which is pressurized to 25MPa by the master station and directly supplied to the vehicle natural gas meeting the national standards.
the 4, nm3/d biogas separation and purification project of Yantai Shuangta Food Company is another 4, nm3/d biogas separation and purification demonstration project undertaken by Kaifeng Yellow River Air Separation Group following the 2, nm3/d demonstration project of Henan Xinyu Energy and the 1, nm3/d demonstration project of Tianguan Group with completely independent intellectual property rights. The group company applied advanced technology and mature experience to standardize the design of the project, and strictly controlled the quality in the process of manufacturing and installation, fully ensuring the advanced technology, reliable quality and stable system operation of the equipment. The commissioning of this project coincided with several cold days. The company's technicians and commissioning personnel worked in the open air under extreme environmental conditions, braved the wind and snow, worked overtime, overcame many difficulties, and successfully completed the commissioning, operation test, experimental research, project acceptance and other tasks, which won a good reputation for the group company.
The successful start-up of the 4, nm3/d biogas separation and purification project of Yantai Shuangta Food Company not only proves that the "bio-natural gas purification" technology independently developed by the Yellow River Air Separation Unit is completely mature, but also indicates that the group company has the design and manufacturing capacity of a full range of separation and purification devices below 1,, and the "bio-natural gas purification" project has entered a new stage of comprehensive promotion and sales.
