Abstract
Thermochemical conversion (TCC) of livestock manure is a novel technology that has shown very promising results in treating waste and producing oil. A batch TCC system that was previously developed was shown to have successfully converted 70% of swine manure volatile solids to oil and reduced manure chemical oxygen demand by up to 75%. Since a continuous-mode system is more applicable for scale-up operations, a bench-scale continuous thermochemical conversion (CTCC) system was developed to evaluate the technical feasibility and economical viability of a pilot plant that is capable of producing oil from swine manure. The system was designed to operate at 305°C and 10.3MPa based on the optimal process conditions derived from the batch-process study. The main components of the system are: a manure preprocessor, a low-flow rate high-pressure slurry feeder, a process gas feeding system, a high-temperature high-pressure reactor, gas and liquid products separation vessel, and process controllers. The bench-scale CTCC unit has a capacity to process up to 3.6 kg of raw manure per hour.
