Biogenic Refinery

A biogenic refinery comprising:

• at least one pyrolysis pot adapted and configured to heat feedstock directed into the biogenic refinery;
• an exhaust plenum into which exhaust from the at least one pyrolysis pot is directed as the exhaust flows to exit the biogenic refinery;
• an inducer fan adapted and configured to draw the exhaust in the exhaust plenum and direct the exhaust to exit the biogenic refinery;
• an auger adapted and configured to remove processed feedstock from at least one pyrolysis pot;
• a drag chain conveyor system having a first drag chain conveyor portion and a second drag chain conveyor portion, the first drag chain conveyor portion being adapted and configured to move feedstock in a direction of advancement along a length of the first drag chain conveyor portion, the first drag chain conveyor portion having a drying region along its length, the drying region of the first drag chain conveyor portion being disposed in the exhaust plenum of the biogenic refinery, the second drag chain conveyor portion being adapted and configured to move the feedstock in a direction of advancement along a length of the second drag chain conveyor, the second drag chain conveyor portion having a drying region along its length, the drying region of the second drag chain conveyor portion being disposed in the exhaust plenum of the biogenic refinery, the second drag chain conveyor portion being adapted and configured to deposit the feedstock in the at least one pyrolysis pot;
• a control system including:
• a drive adapted and configured to control the drag chain conveyor system;
• a humidity sensor adapted and configured to sense moisture in the exhaust and generate a signal corresponding thereto;
• and
• a controller with a processor and a memory;
• wherein the control system is adapted and configured to:
• (i) receive the signal from the humidity sensor;
• (ii) store a plurality of data structures in the memory of the controller, the plurality of data structures comprising a desired moisture level in the exhaust;
• (iii) compare the humidity sensor signal with the desired moisture level in the exhaust;
• and (iv) generate a signal for controlling the drive of the drag chain conveyor system based upon a difference between the humidity sensor signal and the desired moisture level in the exhaust to control a rate of movement of the feedstock through at least one of the drying region of the first drag chain conveyor portion and the drying region of the second drag chain conveyor portion of the drag chain conveyor system.
