Abstract:
1. A self powered method of conversion of disposable hydrocarbons into diesel and heating oil fuels and for conversion of biomass into biodiesel fuel in a three stage heating process comprising: drawing feedstock from a feedstock tank into a preparation tank; preheating the feedstock in the preparation tank to save energy using retained heat in the residuals and #5 heating oil, if any, to warm the feed stock to 125° F. by circulating the residuals and #5 heating oil, if any, through piping in the preparation tank as first and second liquid to liquid heat exchangers; heating the feedstock in a first hot air heat exchanger to drive off light ends and water as steam, which steam is vented by a stack to the atmosphere; heating the feedstock in a second hot air heat exchanger to processing temperature; processing the feedstock in a cracking kettle to produce gaseous #2 diesel and #5 heating oil or biodiesel; incinerating light ends, and if necessary to obtain sufficient heat inferior product and #5 heating oil, if any, or biodiesel to generate heat for the process including especially the first and second hot air heat exchangers; separating the gaseous #2 diesel and #5 heating oil exiting the cracking kettle in a distillation column; converting gaseous #2 diesel fuel to liquid #2 diesel fuel in a condenser; removing particulates and sulfur and lower product temperatures in a filter and chiller unit; storing #2 diesel and #5 fuel oil or biodiesel, and residuals removed from a bottom of the distillation column in storage tanks; and monitoring, configuring, and automating operation of the method using a closed loop control computer programmed with sophisticated software.
