Regenerative vapor energy recovery system and method for use with an ethanol plant. Regenerative vapors are partially condensed in a regenerative precondenser using a warm water stream. The warm water stream is fed to the regenerative precondenser and the partially condensed regenerative vapor stream is sent back to the ethanol plant where the stream is fully condensed using an existing condenser. The ethanol plant is thus operated at greater energy efficiency with lower operating costs than would be achieved with conventional systems.

An extractive distillation column system contains a combination column and a side rectification column. A process can be used for separation of butenes from C4-hydrocarbon streams using the extractive distillation column system.

A distributor tray (100) for a column for contact between a gas (G) and a liquid (L) is provided wherein the distributor tray has a plurality of compartments defined on one face of the tray by secant partitions (104) which are perforated (105) to allow the flow of liquid between adjacent compartments. Each compartment includes at least one passage of the liquid through the tray or a chimney (102) projecting from the tray for the exclusive passage of the gas (G) through the tray. The shape of the chimney is identical to the shape of the compartment containing it, and the chimney has an internal volume at least equal to the volume of the compartment containing it.

A liquor distillation system, comprising one or more channeled loops fluidly couplable to a boiler and a condenser, the condenser adapted to condense alcoholic vapors from a heated liquor wherein the one more channeled loops include an entrance point, an exit point, a split point, and a recombination point such that the heated liquor enters the one or more channeled loops from the entrance point, to the split point where the heated liquor is split into two separate opposite subchannels and recombined at the recombination point; one or more connection pipes adapted to connect the one or more channeled loops to another channeled ring; one or more drain valves; and a liquor outlet.

A distributor element comprising: at least three plates, each plate comprising openings, each of the levels between adjacent plates having walls extending from one side of one plate onto an adjacent side of an adjacent plate to define a channel, the channels fluid-tightly connecting all of the openings between adjacent plates, in each of the levels between the walls, one or more hollow spaces being formed, each of the plates comprising at least one aperture not being fluid-tightly connected with the openings of an adjacent plate by a channel, in each level between the at least one aperture of the adjacent plate at least two fluid paths extend in the one or more hollow spaces, all of the at least two fluid paths of each level having a substantially same length, and a number of fluid paths increasing at least for 75% of the plates from level to level.

The present invention relates to processes of recovering oil after liquefaction and/or from thin stillage and/or syrup/evaporated centrate from a fermentation product production process by adding a thermostable protease to the whole stillage, thin stillage and/or syrup.

A continuous distillation process comprises the following steps: putting a material into a multilayer distillation tower to enable the material to sequentially undergo preheating, extrusion pricking, steam distillation, meal roasting, drying and cooling treatment, condensing essential oil-containing steam, and carrying out water separation, so as to obtain an essential oil.

The present invention is related to an advanced control method—including a fast response method—to stabilize, optimize and or maximize the output flow of an evaporation unit via ultrasonic controlled sound or vibration applied to the said evaporation unit. The invention further provides equipment wherein said method is being implemented, such as an evaporation or separation unit.

The present disclosure relates to methods for processing plastic waste pyrolysis gas, such as methods wherein clogging of the systems used in the method is avoided or at least alleviated.
