Definitions
- the invention relates to an apparatus for
- homogenizing cellulosic or lignocellulosic biomass by imposing tangential shear on the biomass while it is simultaneously exposed to a flashing operation, and more specifically, to a combined tangential shear homogenizing and flashing apparatus having a uniform rotor/stator gap dimension .
- Biomass can be aquatic or terrestrial plants.
- Specific biomass sources include macroalgae (kelp) , microalgae, energy crops
- biomass processing byproducts e.g., woodes, trees, crop residue (e.g., corn stover, forestry byproducts) , biomass processing byproducts
- the first step of destructuring is
- pretreatment commonly referred to as pretreatment.
- Such chemical pretreatment methods may be used in combination with mechanical pretreatment techniques that impose physical deformations on the biomass.
- mechanical pretreatment techniques involve the use of apparatus that subject biomass at elevated temperatures and pressures to operations such as mixing, grinding and/or milling. These activities facilitate size
- the state of the biomass may be altered to the extent that portions of the biomass dissolve, liquify and/or melt.
- pretreated biomass ranges from solids, to compressible solids, to molten material and liquids or mixtures thereof.
- the increased shear in the high velocity two-phase flow introduces gradients that disrupt some of the biomass structure.
- shear fields are in the flow direction, although turbulence may exist.
- the magnitude of the shear is dependent on the combination of the flow properties of the pretreated materials and the change in state for the apparatus (i.e., temperature and pressure). Thus, the shear is difficult to control independently of the biomass fluid properties.
- the flashing operation can be compromised by variations in the quality of the pretreated biomass flow characteristics and particulate size resulting in erratic performance or pluggage in the flash device.
- the pretreated biomass quality is a function of the

- the present invention relates to a method, apparatus and system for destructuring pretreated biomass at above atmospheric pressure and at an elevated temperature by discharge of the same into a reduced pressure zone (a flashing operation) defined within the housing of a combined tangential shear homogenizing and flashing apparatus that includes a stator and a relatively movable rotor. While the material is being subjected to flashing a tangential shearing force is imposed on the material by the action of the relatively moving rotor and stator. Introducing an independent tangential shear in a rotating device during the flashing operation homogenizes the volume of pretreated biomass.
- the apparatus provides inherently more stable performance due to the ability of the rotation to shear particles to a more acceptable size while systematically sweeping potential particle
- the invention is directed to a combined tangential shear homogenizing and flashing apparatus having various configurations of rotor and stator that results in different axial dimensions being defined therebetween the rotor and stator.
- the gap defined between the rotor and stator and/or the rotational speed of the rotor is/are varied in accordance measured parameters of the pretreated biomass, such as pressure, temperature, particle size and/or material composition.

- the system 10 includes a pretreatment device 12 operative to pretreat one or more stream (s) 14 of raw cellulosic feedstock with processing aids such as water, solvents, compatabolizing agents, acids, bases and/or catalyst in preparation for destructuring and other further operations.
- processing aids such as water, solvents, compatabolizing agents, acids, bases and/or catalyst in preparation for destructuring and other further operations.
- Any suitable pretreatment operation on the biomass may be performed within the pretreatment device 12, as, for example, agitating, washing,
- Pretreated material from the source 12 is conducted through a feed line 16 to a combined tangential shear homogenizing and flashing apparatus 20 also in accordance with the present
- the combined tangential shear homogenizing and flashing apparatus 20 itself comprises a housing 20H having an inlet port and channel 201 and at least a first effluent output port 20E 1 . However, it lies within the contemplation of the present invention to provide a separate second output port 20E 2 for the housing 20H.
- a stator 20F and a rotor 20R are disposed within the housing 20H in confrontational orientation with respect to each other. In the arrangement illustrated in Figure 1 the rotor and stator are parallel to each other and are oriented substantially perpendicular to the axis 20A.
- the stator 20F is secured in a fixed disposition at any convenient location within the housing.
- the rotor 20F is secured in a fixed disposition at any convenient location within the housing.
- the shaft 20R is mounted on a shaft 20S for relative rotation with respect to the stator.
- Motive force for the rotor 20R is provided by a drive motor 20M connected to the shaft 20S.
- the shaft 20S aligns with the axis 20A of the apparatus 20.
- the stator 20S and the rotor 20R cooperate to define a mixing zone 20Z therebetween.
- the inlet channel 201 is connectible to the feed line 16 and serves to conduct pressurized biomass material from the pretreatment device 12 into the entrance region 20N of the mixing zone 20Z located in the vicinity of the axis 20A.
- the exit 20T of the mixing zone 20Z is disposed at the radially outer edge of the rotor 20R and communicates with the interior of the housing 20H and thus, with the first effluent output port 20E ! and the second output port 20E 2 , if present .
- the rotor and the stator are each substantially disk- shaped members.
- the rotor and stator can have any convenient three- dimensional configuration, peripheral shape and size.
- the surfaces of the rotor and stator can be smooth or patterned with groves or elevated sections so as to facilitate particle size reduction.
- the rotor, stator, housing may be preferably made from stainless steel.
- the apparatus 20 assists in the destructuring process by homogenizing the pretreated biomass while simultaneously causing a partial phase separation of the homogenized biomass into vapor and liquid phases.
- the distinct liquid and vapor phases so produced may be conducted singly or together directly to a processing utility 28 disposed downstream of the apparatus 20. If only a single effluent output port 20E 1 is provided both the liquid and vapor phases resulting from the homogenization and flash of the biomass are conveyed through a first conduit 22 to the utility 28. If the housing 20H is provided with a second output port 20E 2 the vapor phase is carried via the conduit 24 to the utility 28 and the liquid phase is conducted separately to the utility 28 through the first conduit 22.
- Representative of the various processing devices that may be used for the utility 28 include an agitating vessel for further destructuring.
- flashed vapor of the biomass leaving the housing through the second outlet port 20E 2 may require different processing.
- conduit 24 may be connected to an alternative processing utility 28A in which the vapor phase may be isolated for recycling and re-use or refined for various applications.
- conduits 22, 24 provide direct, uninterrupted fluid communication between the respective outlet ports 20E lr 20E 2 and the particular utility(ies) 28, 28A to which they are connected.
- direct means that
- effluent (s) from the mixing zone 20Z is (are) conducted to their respective destination ( s ) without any impediment to fluid communication and without the need to pass through a separate intermediate device (such as a discrete flash or metering device) .
- the dimension of the mixing zone 20Z may be measured in a direction parallel to the axis 20A and is determined by the magnitude of the axial gap 20G between the rotor 20R and the stator 20F. Since in Figure 1 the rotor and stator are arranged parallel to each other and are situated substantially perpendicular to the axis 20A, the gap 20G, and thus the axial dimension of the mixing zone, is uniform across the across the full radial extent of the mixing zone 20Z.
- the confronting surfaces of the rotor and/or stator in any embodiment of the invention are patterned with grooves and/or elevated sections to facilitate homogenization the axial dimension of the gap between the rotor and the stator is defined as the underlying surface should the grooves and elevated sections be eliminated.
- the dimension of the gap 20G may be adjusted by relocating the rotor with respect to the stator.
- Suitable expedients for manually adjusting the axial dimension of the gap prior to operation include shims, threaded shaft components, and hydraulic positioning devices.
- the dimension of the gap is automatically adjusted during operation by a gap adjustment control system 34 to be described.
- the axial dimension of the gap is initially sized to a predetermined value based upon the particular pressure, temperature and nature of the biomass to be destructured . This initial sizing of the gap sets the predetermined appropriate initial axial dimension of the mixing zone 20Z.
- predetermined pressure and temperature is introduced into the mixing zone 20Z through the inlet port 201.
- the sensor 30 may include one or more sensing devices operative to monitor parameters such as pressure, temperature, particle size and/or composition (e.g., nature) of the pretreated influent biomass .
- substantially radially outward direction through the mixing zone 20Z is controlled by the pressure difference between the entrance 20N and exit 20T.
- the pressure gradient vector indicative of the change in pressure through the mixing zone, is indicated in the drawing by the vector P.
- the motor 20M rotates the rotor 20R with respect to the stator 20F.
- the shear field imparts a
- the tangential shear force homogenizes the pretreated biomass while the pressure difference across the mixing zone causes a partial phase separation of the homogenized biomass into vapor and liquid phases.
- the phase separation may occur within the radial extent of the mixing zone or within a predetermined close distance from the exit 20T thereof. In the case illustrated in Figure 1 the partial phase separation occurs within the mixing zone.
- selection of the predetermined initial size of the gap 20G coupled with the pressure differential and temperature of the biomass cause a partial phase separation of the homogenized pretreated biomass into vapor and liquid phases such that the biomass undergoes at least a three-fold total volumetric increase and a weight transition to a vapor state of at least one percent (1%) .
- the resulting pretreated biomass in the flow line 16 may contain significant variations in fluid properties as well as size of discrete particles.
- the gap adjustment control system 34 enables the apparatus 20 and a system 10 incorporating the same to adapt automatically to adjust the gap 20G between the rotor and the stator and to compensate for such

- the gap adjustment control system 34 may further include actuator 36 operatively connected to the motor 20M to physically effect
- the actuator 36 responds to a control signal from the control system 34 carried on a line 34A to move the motor and the rotor connected thereto as a unit toward and away from the stator thus to vary the gap dimension of the mixing zone based upon various measured parameters of the influent pretreated biomass.

- the gap dimension may be varied in a time-controlled manner to expel troublesome particles.
- the gap dimension may be altered by displacing the stator within the housing relative to the rotor.

Similar to the situation in Figure 1, with the arrangement shown in Figure 2 the flash occurs within the radial extent of the mixing zone.
- the location of the flash can be adjusted by
- Figures 3 and 4 illustrate two forms of an alternate embodiment of the apparatus 20 in which the mixing zone 20Z defined by the gap 20G between the rotor and stator has a non-uniform dimension.
- the largest axial dimension 20G L of the gap, and thus of the mixing zone is located in the vicinity of the entrance 20N.
- one (or both) of the rotor and/or stator is (are) frustoconically shaped members that are inclined with respect to the axis 20A such that the members taper uniformly toward each other at positions radially outwardly from the axis 20A.

- the partial phase separation occurs just past the
- the arrangement shown in Figure 4 illustrates an construction in which the smallest axial gap dimension 20G S , and thus the restriction to biomass flow, occurs at a selected location radially inwardly from the exit 20T of the mixing zone 20Z.
- the flow restriction should be not more than one-third of the radial distance of the mixing zone inwardly from the exit of the mixing zone.
- the restriction is defined by a constrictive feature 20K that is formed in the stator 20F. The partial phase separation occurs within the mixing zone in the vicinity of the feature 20K. It should be understood that an analogous feature may alternatively or additionally be provided on the rotor 20R.
