One device used in this activity uses electrodes to generate primary and secondary coalescent regions in an  effort to control electrolytes, however the formation of rag layers can disrupt that step of this activity.
One device used in this activity uses electrodes to generate primary and secondary coalescent regions in an  effort to control electrolytes, however the formation of rag layers can disrupt that step of this activity. UOP  makes large industrial machinery for this process. One of the first steps in this process is to run the feed  material through a desalter. Cyclones and stripping streams are used to accomplish the FCC part of this  activity, which is one of the most economically feasible components. One step in this process is accomplished  by a catalyst consisting of platinum on either an alumina or rhenium base. The central devices used in this activity  are VDUs and CDUs. Visibreaking reduces viscosity during this activity. Delayed coking is used to handle resids in  this activity, which are heavier inputs. Zeolites are used as a catalyst in the cracking part of this process where long  molecules are chopped into smaller units. This process can produce Naptha and Parafins. For 10 points, name this  activity by which fractions of hydrocarbons are separated and processed for use.
