Abstract

The present invention is a self-powered method for conversion of disposable hydrocarbons into diesel and heating oil fuels and conversion of biomass into biodiesel fuel. The method is operated using a feedstock tank, a preparation tank for first stage warming of the feedstock, a first heat exchanger to separate out water as steam and light ends, a stack to vent steam to the atmosphere, a second heat extension to raise the temperature to the necessary for processing the feedstock in a cracking kettle, a fume incinerator burning the light ends to generate heat for the first and second heat exchangers, a distillation column to process the gases from the cracking kettle, a condenser to convert gas to liquid #2 diesel fuel, a filter and chiller unit and storage tanks to hold the fuels and residuals. The method uses retained heat in the residuals to preheat the feedstock to save energy.

Dependent claims

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.
