Action 1: Energy saving for hydrogen containing tail gas recovery and utilization - The hydrogen containing tail gas from the Second and Third Plant has been changed from direct emission to being connected to the combustion boiler through pipelines. The tail gas is burned in the boiler to generate steam and transported to the existing steam main pipeline. The exhaust gas is discharged into the atmosphere through denitrification devices and energy-saving devices that meet the standards

Achievement 1: Annual steam production of 17000 tons, annual benefits of 4.6 million yuan, saving 2833 tons of standard coal and 7650 tons of CO2 emissions
