Embodiment Construction
[0086] press now figure 1 , figure 2 Shown technological process and pipeline flow are set forth in detail as the best embodiment of the present invention and implement:
[0087] Process flow of the present invention comprises the steps:
[0088] 1. Compress the treated coke oven gas to 1.0MPa and enter the surge tank.
[0089] 2. The stabilized coke oven gas passes through the gas preheater 1, is heated to 250°C, and then enters the primary methanation reactor 2. A certain amount of self-produced water vapor is added to the primary methanation reactor 2. On the one hand, it can control Warm and heat removal, which is beneficial to the conversion of CO and can prevent CH 4 High temperature carbonation reaction.
[0090] 3. The temperature of the methanation gas in the primary methanation reactor 2 is about 600°C. After heat exchange in the waste heat boiler 5, the temperature is 250°C, and then enters the methanation reactor 3 in the carbon replenishment and hydrogen retu...
