Process and apparatus for producing hydrocarbon fuel from waste plastic

A pyrolysis reactor system for continuously producing a hydrocarbon oil from a melted waste plastic and separating a gaseous hydrocarbon oil from a solid byproduct comprising:

• a reactor body comprising:
• a longitudinal side, a first end, a second end located on the opposite side of the reactor body from the first end;
• a side having a cylindrical shape, connecting the first end and the second end;
• an inside;
• and an outside;
• a first inlet feed connected through the first end, wherein the first inlet feed is capable of transferring the melted waste plastic into the inside of the reactor body;
• a first outlet chamber connected to the second end, the first outlet chamber further comprising:
• an opening positioned along a longitudinal wall of the first outlet chamber,
• wherein the opening is located between about 60 percent and about 90 percent of the length of the longitudinal wall, and
• a grating positioned within the first outlet chamber and connected to the opening, and
• wherein the grating is oriented on an inclined angle of at least 25 degrees;
• a first screw device located on the inside of the reactor body,
• wherein the first screw device is hollow and comprising a heating system;
• a plurality of vapor ports positioned along the longitudinal side of the reactor;
• wherein the vapor ports are capable of removing the hydrocarbon vapor from the inside to the outside of the reactor;
• a second outlet chamber connected to the opening of the first outlet chamber and comprising a discharging end located on the bottom of the second outlet chamber;
• a second screw device,
• wherein the second screw device is connected with the discharging end and the first end of the reactor body at an inclining angle of at least 20 degrees;
• a solid heat transfer medium located inside of the reactor body capable of transferring heat from the heat transfer medium to the melted waste plastic;
• a second screw reactor connected with the first inlet feed of the reactor body, comprising a substantially horizontal cylindrical body having a fifth end and a sixth end opposite the fifth end;
• a third screw device;
• and
• a heating jackets at least partially surrounding the third screw reactor, capable of maintaining the waste plastic in a melted phase;
• wherein the third reactor is capable of transferring the melted waste plastic continuously into the first inlet feed of the reactor body.
