Abstract: A combustible pellet drying system includes a valveless pulse combustor and a drying column. The drying column includes a first drying region and optionally a second drying region. The first drying region receives heated drying gas from the pulse combustor to dry a quantity of moist pellets flowing downwardly through the drying column. Moisture-laden exhaust gas from the first drying region is processed by a condenser to remove water and recover thermal energy therefrom, and to produce a cooled dried exhaust gas which may be reheated by passing through a jacket around the pulse combustor. The reheated dry gas is introduced into the second drying region to further dry the pellets. The second drying region is preferably a downwardly expanding cone configuration. The drying column includes a plurality of temperature sensors. Adjacent temperature sensors may be used to determine a level of pellets within the drying column. The combustible pellets are preferably coal pellets.

Abstract: A system and method for the conversion of free fatty acids to glycerides and the subsequent conversion of glycerides to glycerin and biodiesel includes the transesterification of a glyceride stream with an alcohol. The fatty acid alkyl esters are separated from the glycerin to produce a first liquid phase containing a fatty acid alkyl ester rich (concentrated) stream and a second liquid phase containing a glycerin rich (concentrated) stream. The fatty acid alkyl ester rich stream is then subjected to distillation, preferably reactive distillation, wherein the stream undergoes both physical separation and chemical reaction. The fatty acid alkyl ester rich stream is then purified to produce a purified biodiesel product and a glyceride rich residue stream. The glycerin rich second liquid phase stream may further be purified to produce a purified glycerin product and a (second) wet alcohol stream.

Abstract: A super compactor receives a carbon-containing material and delivers a brick suitable as fuel for power generation. A compaction chamber receives the carbon-containing material and has at least one ram reciprocating along a travel path and exerting a predetermined amount of pressure on the carbon-containing material. The compaction chamber also has an end effector plate or a movable slide gate against which the carbon-containing material is compressed, promoting the removal of moisture from the carbon-containing material, and one or more dewatering apertures or a membrane permitting moisture to pass through but blocking the carbon-containing material. A collector captures the moisture that passes through the dewatering apertures or membrane. A power unit provides power to the at least one ram. A heated extrusion chamber receives the carbon-containing material from the compaction chamber and heats and compacts the carbon-containing material to bind the carbon-containing material into the form of a brick.
