Pitch loading control
DescriptionPitch coke battery cokes instead of coal blend the miPitch coke battery cokes instead of coal blend the middle temperature pitch received from tar handling plant. This aspect results in the following differences with coke oven battery:
- there is no charging car. Pitch loading is implemented throug special pitch mains and valves loacated on the battery roof;
- long coking period. Pitch loading operation duration is about 6-8 hours;
- difficulty with loading end determination.
Proposed process control automation system provides:
- automatic pitch valve control according to push/load schedule;
- pitch coking phase start and end signalling.
