The coking seminars are terrific ways to gain knowledge of all types in dealing with everything from operational problems to safety issues regarding deheading of drums, decoking the drums, heading up the drums, etc. I highly recommend going to one of them and don’t be afraid to appear to be stupid, coker operators are a great group of guys like the ones on this forum that just want everyone in our industry to go home safely to their families when the work day is over. So ask questions, lots of questions, even if one or two of them get a chuckle from the one or two asses in the class. There is a wealth of knowledge out there to tap. This forum is only one place to gain such info. Post your email address on here too. Sometimes people want to help, but want to remain anonymous to the vast majority due to political or liability reasons. Good Luck!
