regarding cycle time, we can use multiple methods….
1. Decrease Heater CoT and form shot coke- This will reduce coke cutting time, but while compensating liquid yields. If you have got a good market for your coke and if any improvement in quality of coke can fetch you more returns, go ahead.
2. Use automatic Shifting tool for Heading / Deheading operation. This will save you around 20 mins per cycle.
