 The place that I'm standing right now is in the EMS Energy Institute, and this is a delayed coaker, and this is a small unit that is typically found in a refinery. This is just a really small size of that type of unit. Basically what happens is the very heavy ends from a distillation unit come in, flow through the unit, and inside the unit it's heated to a certain temperature of around 500 degrees Celsius, and as it's heated it's making a carbon material and then trying to take off as much liquid as possible so that the liquids can be made into various fuels. The materials that are made inside the delayed coaker are carbon materials and gases liquids that are used inside the refinery. The carbon material is used to make metals such as steel and aluminum. We also use this particular unit to try to take the very heavy ends and make sure that we have something to use it for instead of trying to throw it away.
