A fermentation tank includes a tank body, enclosing a cavity therein, having a material inlet and a material outlet; a heat exchange structure, disposed on a wall of the cavity for heat exchanging with the tank body; at least one flow disturbing plate, being an elongated plate, the width direction of the flow disturbing plate being parallel to a radial direction of the tank body, the longitudinal direction of the flow disturbing plate being parallel to a vertical direction, a length of the flow disturbing plate being larger than a width thereof, the flow disturbing plate being arranged in the cavity and connected to the tank body, the flow disturbing plate having a heat exchange channel therein, two ends of the heat exchange channel communicating an exterior respectively so that heat is exchanged between the at least one flow disturbing plate and the cavity.

A method of connecting a heat exchanger, which is used primarily in oil and gas operations to heat tanks of liquids, such as drilling mud, water, heavy oil or other such fluids from freezing or becoming too viscous to pump, to a tank.

A microchannel evaporator includes a plurality of microchannels. Each of the plurality of microchannels includes a first end and a second end. A first end-tank is coupled to each first end of the plurality of microchannels and a second end-tank is coupled to each second end of the plurality of microchannels. A second-fluid inlet is coupled to either the first end-tank or the second end-tank and configured to receive a fluid into the microchannel evaporator and a second-fluid outlet is coupled to either the first end-tank or the second end-tank and configured to expel the fluid from the microchannel evaporator. Each microchannel of the plurality of microchannels includes at least one bend along a length thereof.

A dual fluid heat exchange system is presented that provides a stable output temperature for a heated fluid while minimizing the output temperature of a cooled fluid. The heated and cooled fluids are brought into thermal contact with each other within a tank. The output temperature of the warmed fluid is maintained at a stable temperature by a re-circulation loop that connects directly to the mid portion of the tank such that the re-circulated fluid flow primarily warms only a re-circulation section of the tank. The other, lower flow rate, section of the tank may be positioned so that it has a cooler temperature and thus serves to increase the efficiency of the heat exchange by extracting extra heat energy out of the cooled fluid before it leaves the tank. Alternatively, the low flow rate section of the tank may be warmer than the re-circulated section, and thus allow the re-circulated section to be cooler than the output temperature of the warmed fluid.

A precursor vessel for a vapor deposition process is disclosed. The vessel includes a housing having an inlet, an outlet, and defining an interior volume. A tube is disposed within the interior volume and extends from the inlet to the outlet. The tube has sidewalls defining a flowpath there through. The sidewalls have an internal surface facing the flowpath having a plurality of depressions in the internal surface having a depth and a width. A solid precursor material may be loaded into the depressions. A system including the precursor vessel and a vapor deposition process are further disclosed herein.

A plate heat exchanger and methods of construction and use which allow the plate assemblies used in the exchanger to be easily cleaned and maintained and which allow the plate assemblies to be individually and separately removed from the exchanger for cleaning or maintenance while the exchanger remains online and while the other plate assemblies in the plate heat exchanger continue to operate.

A fluid supply includes a first fluid source configured to supply a first fluid, a second fluid source configured to supply a second fluid, a heat exchanger configured to exchange heat between the first fluid and the second fluid, a first fluid recovery tank configured to recover the first fluid that has passed through the heat exchanger, and a first transfer pipe configured to transfer the first fluid from the first fluid source to the first fluid recovery tank via the heat exchanger. The heat exchanger may be disposed at a vertical level higher than a vertical level of the first fluid recovery tank.

A reaction device is provided with a first wall that defines an interior in which a stirring mechanism is located. A heat exchanger is at least partly provided on the first outer wall surface facing away from the interior and/or on the stirring mechanism, wherein the heat exchanger has a grate structure, and at least two layers are provided which have a grate structure. Thus, it is possible to transfer heat in a precise and efficient manner primarily by means of thermal radiation in endothermic processes at different temperature levels, in particular pyrolysis, gassing, and reforming processes, and thereby use the exhaust heat for other processes.
