Biogas Production
More and more agricultural and dairy farms as well as beef, hog and poultry operations are considering the use of anaerobic digestion for biogas production. These operations typically produce a significant amount of organic matter in the form of manure. Anaerobic digestion is a biological process that breaks down organic solids. Manure can be processed in anaerobic digesters and the byproduct is methane gas. The methane gas can be captured, stored and used to run electrical generators and boilers for use in the farm operations. Heat exchangers can face the following challenges when heating sludge:
