Evaporator Optimization Project Bryan Picou James Roberts
Domino Sugar �Refinery is in Arabi, La �Produce 8 million pounds of sugar per day on average �It is the third largest sugar refinery in the world
Domino Sugar
Evaporator Optimization Project �Steam is one of the most expensive resources for a refinery • Take the current operation of the evaporators and make it more efficient • Take the current operation of the melters and eliminate the steam
Evaporators � Evaporator uses steam in a vacuum to heat the sugar liquor and lower its density � Left over vapors from this process is what we are trying to optimize
Melter �Takes the raw sugar and uses steam to melt this sugar into a liquid. �It uses direct steam injection �Vapors from evaporator will be rerouted to power the melter
