Estimating the term…
An apparatus to effect at least partial breakdown of a discrete material or product item or a combination of discrete material or product items. The apparatus includes a treatment vessel in which the discrete material or product item or combination of discrete material or product items are located for treatment. There is at least one entry for introduction of at least one working fluid, at least one pressurisation arrangement to increase pressure on the material or product item or combination of material or product items within the treatment vessel. At least one decompression arrangement to rapidly reduce the pressure on the material or product item or combination of material or product items within the treatment vessel may also be provided. The at least one pressurisation arrangement and the at least one decompression arrangement are operable to cause repeated pressurisation and rapid decompression on the material or product item or combination of material or product items within the treatment vessel.
An apparatus to effect at least partial breakdown of a material or product item or a combination of material or product items, the apparatus comprising:
An apparatus as claimed in any one of the preceding claims wherein the treatment vessel has a working volume which is variable in size.
An apparatus as claimed in any one of the preceding claims further comprising a mount to locate the material or product item or a combination of material or product items within the treatment vessel to allow the at least one working fluid access to multiple sides of the material or product item or a combination of material or product items.
An apparatus as claimed in any one of the preceding claims further comprising at least one recycle line to recycle of at least part of the at least one working fluid.
An apparatus as claimed in any one of the preceding claims further comprising at least one bypass, purge or exit arrangement connected to an outlet of the treatment vessel to allow a portion of the at least one working fluid to bypass, purge or exit the treatment vessel without being subject to the full process cycle or undergoing full pressurisation and/or depressurisation.
An apparatus as claimed in any one of the preceding claims further comprising monitoring equipment associated with the treatment vessel to monitor and/or control one or more conditions within the treatment vessel.
An apparatus as claimed in any one of the preceding claims further comprising at least one inlet for each of the material or product item or combination of material or product items and the at least one working fluid is provided.
An apparatus as claimed in any one of the preceding claims further comprising at least one outlet for each of the at least one working fluid and the treated material or product item or combination of material or product items, is provided.
An apparatus as claimed in any one of the preceding claims wherein a single arrangement or mechanism is provided to cause pressurisation and depressurisation.
An apparatus as claimed in any one of the preceding claims wherein a movable piston is associated with the treatment vessel to cause pressure increases within the working volume of the treatment vessel.
An apparatus as claimed in any one of the preceding claims comprising a repurposed internal combustion engine to cause the pressurisation and subsequent rapid depressurisation in the treatment vessel.
An apparatus as claimed in any one of the preceding claims further comprising a controller provided to control the at least one pressurisation arrangement or mechanism and at least one depressurisation arrangement or mechanism to define one or more operational parameters of the increase in pressure and depressurisation.
An apparatus as claimed in any one of the preceding claims wherein the at least one depressurisation mechanism is a flash decompression or explosive decompression arrangement or mechanism.
An apparatus as claimed in any one of the preceding claims further comprising an agitator associated with the treatment vessel to agitate or circulate the at least one working fluid within the treatment vessel.
An apparatus as claimed in any one of the preceding claims wherein the at least one working fluid is gaseous.
An apparatus as claimed in any one of the preceding claims wherein the at least one working fluid comprises a mixture of phases.
An apparatus as claimed in any one of the preceding claims wherein the at least one working fluid comprises a mixture of materials.
An apparatus as claimed in any one of the preceding claims wherein the at least one working fluid comprises at least one active component and at least one carrier.
An apparatus as claimed in any one of the preceding claims wherein the pressure increases within the working volume of the treatment vessel are created through the application of heat.
An apparatus as claimed in any one of the preceding claims wherein treatment occurs in an elongate treatment vessel through which the material to be treated is conveyed during treatment.
An apparatus as claimed in any one of the preceding claims wherein the pressure increases in the treatment vessel are created in one or more elevated pressure zones in the treatment vessel using at least one injector, in at least one pulse.
An apparatus as claimed in any one of the preceding claims further comprising at least one depressurisation arrangement or mechanism to rapidly reduce the pressure in the at least one treatment vessel and wherein the at least one pressurisation arrangement or mechanism and the at least one depressurisation arrangement or mechanism are operable to cause repeated pressurisation and rapid depressurisation within the at least one treatment vessel.
An apparatus as claimed in any one of the preceding claims wherein the at least one catalyst is included in the treatment.
An apparatus as claimed in any one of the preceding claims wherein any pressure decreases within the working volume of the treatment vessel are created through the removal of heat.
