Abstract: An autoclave system comprises an autoclave vessel 210, for performing a leaching operation on sacrificial ceramic cores (not shown) and a storage vessel 220 for containing caustic leaching fluid 230. Interposed in a fluid flow path between the vessel 210 and the tank 220 is a heat exchange unit 240, comprising a body 250 containing a thermal exchange medium, in the form of water 260, and first and second thermal exchange conduits represented at 270 and 280. A thermal exchange medium inlet pipe 290a and a thermal exchange medium outlet pipe 290b are provided to the body so that the medium 260 can be replenished, preferably substantially continuously, to optimize thermal transfer efficiency.

Abstract: 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.

Abstract: There is provided a process and an apparatus for urea production in which preheating of raw material ammonia or heating in a medium-pressure decomposition step can be performed at a relatively low pressure while preventing decrease in an overall heat transfer coefficient. A process for urea production includes: a synthesis step of generating a urea synthesis solution; a high-pressure decomposition step of heating the urea synthesis solution to separate a gaseous mixture containing ammonia and carbon dioxide from the urea synthesis solution; a condensation step of condensing the gaseous mixture; a medium-low-pressure steam generation step of reducing a pressure of medium-pressure steam condensate obtained in the high-pressure decomposition step to a medium-low pressure to generate medium-low-pressure steam and medium-low-pressure steam condensate; and one or both of a medium-pressure decomposition step and an ammonia preheating step.

Abstract: This invention is for improving the manufacturing pharmaceutical grade CBD and other cannabinoids following current Good Manufacturing Practices (cGMP) of the US FDA for use in clinical trials for CNS and other indications by the NIH and other researchers. The major cannabinoids in marijuana (Cannabis) and hemp originate from Cannabigerolic Acid (CBGA) present in the biomass of the plant. Plant enzymes that are specific to different strains of biomass converts CBGA to different carboxylic acids of cannabinoids including Cannabidiolic Acid (CBDA) and Δ9-Tetrahydrocannabinolic Acid (Δ9-THCA). These are relatively stable in the growing and fresh-cut plants. These are converted by thermal decarboxylation to Cannabidiol (CBD) and Δ9-Tetrahydrocannabinol (Δ9-THC), carbon dioxide and water. Cannabinoids can be manufactured by first heating the Cannabis biomass to convert carboxylic acids prior to extraction and purification. Alternatively, and preferably because of manufacturing cost and product stability, the carboxylic acids can be first extracted and purified. They can be utilized in the carboxylic acid form or stored in a stable manner until converted to cannabinoids for use in medicine. This invention provides an efficient method for their conversion utilizing a high-pressure reactor under inert conditions.

Abstract: A pulsed compression reactor may include a reactor housing, a spring piston, and a driver piston. The reactor housing may define an interior volume, and may include a first passage and a second passage which lead to the interior volume. The spring piston may be positioned within the interior volume, wherein the spring piston and the reactor housing at least partially define a perimeter of a gas spring buffer chamber within the interior volume. The driver piston may be positioned within the interior volume, wherein the spring piston, the driver piston, and the reactor housing at least partially define a perimeter of a reaction chamber within the interior volume.

Abstract: This disclosure relates to systems and processes for cooling polymer product mixtures manufactured at high pressure. The processes of the invention involve cooling and then subsequently reducing the pressure of the product mixture from the reactor. In the systems of the invention, a product cooler is located downstream of the high pressure reactor and upstream of a high pressure let down valve.
