The present disclosure relates to methods and systems for concentrating a solids stream recovered from one or more process streams derived from a beer in a biorefinery by exposing the recovered solids stream to an evaporator system to remove moisture therefrom and form a concentrated, recovered solids stream.

Methods and systems for concentrating a solids stream recovered from a process stream in a biorefinery

The present disclosure includes systems and methods for hydrolyzing (e.g., pretreatment and/or enzymatic hydrolysis) lignocellulosic biomass into one or more sugars such as pentose and glucose sugars. The present disclosure includes configurations that incorporate flashing and/or liquid cooling so as to permit desirable throughput. The present disclosure also includes a liquefaction configuration so as to permit desirable (e.g., continuous high volume) throughput.

Systems and methods for processing lignocellulosic biomass

The present disclosure relates to methods and systems for regenerating molecular sieves used in an alcohol dehydration process after the molecular sieves have become saturated with water.

Methods of regenerating molecular sieves, and related systems

Provided are methods and systems of propagating a microorganism on a stillage composition. The methods involve growing microorganisms in a propagation medium formed from a polysaccharide-containing stillage composition with the majority of the of the polysaccharides in the propagation medium coming from the stillage composition. The propagation medium also includes cellulases and/or amylases to form monosaccharides from the polysaccharides. A first cell mass is grown in the propagation medium to form a second cell mass which is greater than the first cell mass.

Methods and systems for propagating microorganisms on stillage compositions

The present disclosure includes embodiments of methods and systems for reducing the size of lignocellulosic feedstock. The present disclosure also includes embodiments of methods and systems for separating oversized, in process lignocellulosic material, reducing the size of the oversized lignocellulosic material offline, and the reintroducing the lignocellulosic material back into the main process flow after size reduction.

Methods of reducing the size of lignocellulosic material, and related systems

A system for transferring heat from an ethanol and water vapor stream is disclosed as having a first heat exchanger, a valve system coupled to first heat exchanger and a first tank, a second tank coupled to the valve system, a second heat exchanger coupled to first tank and second tank, and a pipe line connecting the second tank to the first heat exchanger. A method for transferring heat is provided and involves intermittently cooling a first media, transferring heat from the first media to a second media, and directing the second media to a valve system. The valve system directs a flow of the second media to the first tank when a temperature of second media is above a temperature set point and directs the flow of the second media to the second tank when the temperature of second media is below the temperature set point.
