What is the general production process in coal coking, and what do coking engineers do?
Reply #22010-09-14
The workshops commonly found in coking plants are: the coal preparation workshop, the coking workshop, and the chemical products workshop; if conditions permit, there may also be a methanol workshop. First is the coal preparation workshop, where the coal is crushed and different types of coal are mixed in specific proportions. The resulting mixture is then transported via conveyor belts to the coal storage tower in the coking workshop. There, coal loading vehicles (or ramming coal loading vehicles) are used to load the prepared coal into the coke ovens. Inside the carbonization chambers, which are at temperatures over 1300 degrees, the coal undergoes dry distillation over a certain period of time to turn into coke. The coke is then guided out using coke guiding vehicles, and pusher vehicles transport the mature coke to the coke quenching vehicle. This vehicle takes the coke to the coke quenching tower to cool it down. After cooling, the coke is placed on a coke drying platform, from where it is transported via conveyor belts to large and small vibrating screens. After sorting, it is sent to the coke storage silos. The raw gas generated during coking is sent to the chemical production workshop, where it undergoes processes such as gas-liquid separation, initial cooling, electrostatic tar capture, naphthalene removal, desulfurization, denitrification, final cooling, and benzene removal to become clean gas. These are just brief introductions.
