摘要:
Bromine containing compounds, such as calcium bromide, sodium bromide and the like, are prepared in high purity and more quickly with less waste by using a process with two bromination stages and often a third step wherein the crude product mixture can be adjusted to meet specific product requirements. In the first bromination stage, the majority, but not all, of a substrate is brominated usiung a reductive bromination reaction, the remaining unreacted substrate is converted to product in the second stage through another a reductive bromination reaction, although the specific reagents may be different, wherein the addition of bromine and a reducing agent are carefully monitored.

The present application is directed towards systems and methods for continuously reacting a combination of materials by use of an acoustic agitator and a continuous process vessel. The system can react, fluidize, mix, coat, dry, combine or segregate materials. The continuous processing system can include an acoustic agitator capable of being removably coupled to a continuous process vessel. The continuous process vessel can include a first inlet for introducing at least one process ingredient, a plurality of plates configured for directing a flow of the at least one process ingredient through the continuous process vessel and capable of transferring acoustic energy generated by the acoustic agitator into the at least one process ingredient, an outlet for discharging a product of the at least one process ingredient, and a fastener for removable coupling the continuous process vessel to the acoustic agitator.

The invention relates to a tubular flow module comprising at least two concentric tubes (1, 2) with spiral features, wherein tube (2) is coaxially arranged inside tube (1) and each tube has a maximum diameter and a minimum diameter, wherein the maximum diameter of tube (2) is larger than the minimum diameter of tube (1), defining a flow path (3) for fluids between tube (1) and tube (2). The invention relates further to a tubular flow module system and use of the tubular flow module.
摘要:
Improved design of a catalytic reactor for the production of methanol at equilibrium conditions whereby methanol as it is formed is separated from the gaseous phase into the liquid phase within the reactor, without reducing the catalytic activity of the methanol catalysts This is achieved by adjusting the boiling point of a liquid cooling agent being in indirect contact with the catalyst particles and by providing a specific ratio of catalyst bed volume to cooling surface area. Thereby, condensation of methanol as it is formed in the gaseous phase takes place at the cooling surface arranged evenly distributed within the reactor and within a very limited region of the catalyst bed.

A catalyst conduit for a catalytic reactor (10) of a turbine combustor, the conduit comprising a tube (14) including an inlet (26) and an outlet (32), and a wall with an interior surface (34) and an exterior surface (36). The tube (14) contains a variation in its cross sectional area along at least a portion of its length to change a property of a fluid flowing adjacent the wall of the tube (14). An oxidation catalyst (44) is deposited on at least a portion of the tube (14).

A baffle (32) includes a body member having a first surface (34), a second opposed surface (36), and an outer peripheral edge (38). An aperture (40) may be formed through the body member so as to define an inner peripheral edge (42). The inner peripheral edge (42) is distorted so as to be non-planar. An apparatus (10) includes a first conduit (14) having a first end, a second end, and a first channel extending therebetween. At least one baffle (32) is disposed in the first channel and includes a body member having a first surface (34), a second opposed surface (36), and an outer peripheral edge (38). At least one aperture (40) may be formed through the body member to define an inner peripheral edge (42). The inner peripheral edge (42) is distorted so as to be non-planar. A second conduit (12) may be disposed inside the first conduit (14) and extend through the aperture (40) in the baffle (32). The apparatus may, for example, be configured as an ultraviolet light reactor, a heat exchanger, or a static mixer.
