Biogas Production

Biogas-ProductionMore 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:

Biomass & Cellulosic Pretreatment

Biomass-and-Cellulosic-PretreatmentBiomass pretreatment is the initial stage of preparing hemicellulosic materials such as corn stover, grass, straw and wood fiber for ethanol conversion.

  • Hemicellulose is the part of the carbohydrate portion of plants such as grass, corn stover, straw and trees, to mention a few. Like conventional starch conversion to ethanol, hemicellulosic materials can be converted to sugars and fermented to create ethanol, bio-diesel or other useful products
  • All structural plant matter is a combination of cellulose, hemicellulose and lignin. Only the direct cellulose is readily convertible to fermentable products. Hemicellulose must be converted to a fermentable form of sugar and lignin is generally not convertible and must be removed

Grain Ethanol Processing

Grain-Ethanol-ProcessingThe OptiShear jet cooker is designed for starch cooking, wet mill processing of starch, ethanol production and fructose and alcohol production. ProSonix's unique method of direct steam injection utilises internal steam modulation via an integral Pneumatic Actuator and variable position steam plug, to accurately meter the mass flow of steam, through choked flow conditions. 'Choked flow' is the phenomenon of accelerating a vapor to maximum velocity by creating a pressure differential through an engineered opening. By establishing choked flow, the steam mass flow can be metered to precisely control the heating of the liquid. This produces predictable results based on the position of the steam plug. Through a variable-area steam diffuser, steam flow is metered at the point where steam and liquid first contact and mix.
