Scott I don't feel you were wrong in posting what you posted. Maybe a tad harsh but we have to be that way sometimes to get people to understand the dangers in what we work with in refining. But what has been done now is basicly one of the the process has been shown on this forum. Now as far as I know this is the first time this has been divulged here on this forum. So now when a search is done through the forum or the internet it will come to this thread some where down the line. There is more that needs to be learned by anyone that attempts to use this procedure or any other one for that fact. I agree that we need to be vigilant in watching out for everyones safety when posts like this are made. IHO we should guide them to the GRF and refrain from posting procedures here on the forum. You have done an exellent job of guiding people here on the forum. Wouldn't it have saved a lot of problems if you would have said the OP was incorrect in his thinking and guided him to the GRF and let it be handled there?
