Biogenic Refinery with SCR System Using Urea Extracted from Feedstock

A method of processing a feedstock comprising sanitary products with human waste in a biogenic refinery, the method comprising:

• shredding the feedstock to reduce a particle size of the feedstock;
• separating liquid and solid components of the feedstock;
• transferring the solid components of the feedstock to a conveyor;
• with the conveyor, moving the solid components of the feedstock to at least one pyrolysis pot of the biogenic refinery;
• heating the solid components of the feedstock in the at least one pyrolysis pot of the biogenic refinery to generate an exhaust from the heating of the solid components of the feedstock in the at least one pyrolysis pot;
• directing the exhaust from the heating of the solid component of the feedstock in the at pyrolysis pot to a plenum that extends, respectively downstream, to a pollution control device and a heat exchanger as the exhaust flows to exit the biogenic refinery;
• directing the liquid component of the feedstock through the heat exchanger;
• heating the liquid component of the feedstock with the exhaust from the heating of the solid component of the feedstock in the at pyrolysis pot to concentrate the liquid component of the feedstock;
• and
• injecting the concentrated liquid component of the feedstock into the exhaust in the plenum prior to the exhaust flowing to the pollution control device.
