摘要： A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750 F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.

摘要： Provided herein are components for a fluid network, specifically a U bend structure connected to at least two pipes which is modified for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The U bend structure is so designed to have a specific ARQ between 1.0 to 1.02 for 5% of the flow passage from the inlet and from the outlet, and an ARQ from 1.02 to 1.15 over the remaining 90% of the flow passage through an Rb/D ratio being greater than 1 and less than 4.

摘要： A heat exchanger includes a casing configured to direct a working fluid therethrough, and at least one heat exchanger (HE) section in the casing. Each HE section includes a pair of spaced supports. The spaced supports include: an upstream support and a downstream support with at least one of them including a coolant carrying body configured to direct a coolant therethrough. A first cross-support couples to and extends between respective upstream and downstream supports; and at least one second cross-support couples to and extends between the respective upstream and downstream supports. Cross-supports are vertically distanced from adjacent cross-supports. A plurality of tube positioners coupled to each cross-support position a plurality of heat exchange tubes extending across a working fluid path through the casing. The tube positioners and the cooling of the cross-supports allows ferritic material to be used for once-through, duct-fired HRSGs.
