Henan Future Energy Technology Co., Ltd., established in 2008, specializes in rural waste (planting straw, livestock and poultry breeding sewage, kitchen waste, domestic waste) treatment and comprehensive energy development technology development, design, construction and equipment manufacturing, technology Service high-tech enterprises.
The company closely followed the national development strategy, and after repeated inspections and demonstrations, technical exchanges and other efforts, DEAR signed a set of 20,000 cubic meters per day of straw biogas purification compressed natural gas project with our company; this project can be completed and put into production, it is inseparable open DEAR technical support and national support.
Eat organic waste, produce natural gas and organic fertilizer, biological natural gas can turn waste into treasure, and it has both economic and ecological value. In 2019, the National Development and Reform Commission, the Ministry of Ecology and Environment, the Ministry of Agriculture and Rural Affairs and other departments issued the "Guiding Opinions on Promoting the Development of Industrialization of Biogas" and proposed that by 2025, the annual output of biogas will exceed 10 billion cubic meters; by 2030 Its output exceeds 20 billion cubic meters, and its scale ranks among the highest in the world.
DEAR air separation, as a professional unit in China's gas separation industry and a national high-tech enterprise, has unique advantages in the production of oxygen, nitrogen, and argon in air separation. Coke oven gas purification, gas purification, etc. have also achieved great results (Note: there are 20,000, 30,000, 40,000, 60, 80, and 100,000 different grades of performance and technology), with design , one-stop service system for manufacturing, installation, and also has the highest domestic pressure vessel manufacturing and installation qualification certificate.
