As with most people, I am looking for ideas to decrease cycle time. We are currently at a 16.5-17 hour cycle. Are there any new projects / upgrades / operational changes that have resulted in a decreased cycle time. I know this is very vague, but right I am just searching for new ideas, if you have specific questions, let me know.

I am also looking for ways to improve cycle time and safety while we are at it. A couple of initiatives that we are currently going after: Delta Valve for bottom unheading and auto-switch drill bits. [;)]

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.

AnonymousA few ideas.
-Look at your cools, can you increase the rate that you cool a drum? Install/clean exchangers to assist in cutting down the cool time.
-Do you have the ability to steam purge a drum during the same time you do a steam strip? (this step alone helped knock off 30-45 minutes) -

Can you please explain more on 2nd point – “Do you have the ability to steam purge a drum during the same time you do a steam strip? (this step alone helped knock off 30-45 minutes) “. We are running with 24 hr cycle and making anode grade coke.
