A slurry polymerization process comprising polymerizing monomers in a reactor comprising baffles, a first slurry feed line for returning cooled slurry from a cooler and optionally a second slurry feed line for transferring reactor slurry from a previous reactor of a cascade of polymerization reactors, wherein the baffle top, the first slurry feed line discharge end and the second slurry feed line end are located below the reactor liquid level.

Disclosed is a jacketed, tiered baffle, bioreactor tank comprising an outer cylindrical-shaped jacket and a cylindrical tank having an inner tank surface defining a chamber configured for supporting a flexible bag disposed within the chamber, and an outer tank surface having tiered baffles configured for routing a heat exchange fluid around the entirety of the outer tank surface, the cylindrical tank disposed axially within the outer cylindrical-shaped jacket. The outer cylindrical-shaped jacket is sealed to the cylindrical tank in a manner sufficient to prevent or minimize loss of the heat exchange fluid.

Apparatus and methods are provided for converting methane in a feed stream to acetylene. A hydrocarbon stream is introduced into a supersonic reactor and pyrolyzed to convert at least a portion of the methane to acetylene. The reactor effluent stream may be treated to convert acetylene to another hydrocarbon process.

Disclosed is a heat exchange module for use in a chemical, pharmaceutical or biological reactor system, the module configured to be disposed in the reactor system having a flexible single use container, and including at least one thermally conductive surface adapted to contact the flexible single use container to facilitate heat transfer, and a fluid circulation path through which a heat exchange fluid can be circulated.

Embodiments of the present disclosure generally relate to apparatus and methods for producing carbon nanomaterials and the collection, storage, and reuse of byproducts produced therefrom. In an embodiment is provided an apparatus that includes a reactor adapted to process a carbon containing feed, a product filter system coupled to the reactor, a fin fan cooling apparatus coupled to the product filter system, an effluent chiller coupled to the fin fan cooling apparatus, a gas/liquid separator coupled to the effluent chiller, a waste liquid containment unit coupled to the gas/liquid separator, an activated carbon filter coupled to the gas/liquid separator, and a process vent coupled to the activated carbon filter.

A system of treating waste materials (28) is provided, and includes a waste treatment reactor (10) configured to treat the waste materials. The waste treatment reactor (10) has a cylindrical body (12) having an inlet (14) to receive the waste materials, a waste chamber (26) to store the waste materials, and an outlet (16) configured to deliver treated waste materials out of the waste chamber. A bundle reactor (38) has the waste treatment reactor and performs a waste treatment for the waste materials stored in the waste chamber. An energy recirculation assembly (40) is connected to the bundle reactor and recirculates thermal energy associated with the bundle reactor during the waste treatment. The energy recirculation assembly (40) has a heating unit (42) to heat a first region of the bundle reactor, and a cooling unit (44) to cool a second region of the bundle reactor.

A system for controlling contamination in hydrogen production from water-reactive aluminum includes at least one reaction vessel. For example, each reaction vessel may include a container, a conduit, and a plurality of baffles. The container may define a volume, and the conduit may define an orifice outside of the container and spaced away from the container. The plurality of baffles may be disposed in the volume to form a tortuous flow path through the volume to the orifice of the conduit to facilitate rapid production of a large quantity of hydrogen from water-reactive aluminum while reducing the likelihood that ejecta, aerosols, or a combination thereof, may escape the reaction vessel to interfere with end-use of the hydrogen produced.
