RE:Can they get rid of the mechanical agitators?there are different ways to agitate for sure. The abrasive nature of the feedstock is an issue but this has been over come in other industries so this shouldn't be a deal breaker. Its a matter of do they have the right engineers/consultants at their disposal that can come up with the right solution. They likely need to separate the process as they are trying to do heating and mixing in the reactor. There are multiple was they could go about this. Right now I am hoping they are following proper root cause analysis protcols and going through the heirarchy of measures appropriately
