WebJun 19, 2013 · The pressure decreases down the length of the reactor, and thus the volumetric flow rate increases. As a result, the concentration of the reactant decreases (in addition to the decrease due to conversion), which lowers the rate of reaction. The Ergun equation for pressure drop in a packed bed reactor (PBR) is: , , , WebFor small-diameter reactors, the pressure drop is higher, which increases the volumetric flow rate and reduces the residence time; this lowers conversion. Since heat transfer is more efficient for smaller-diameter reactors because the surface area per volume is larger, the temperature increases less; this also lowers conversion.
WebSo, how to solve the pressure drop problem? (Especially if nothing can be done about the influx of particles?) Install a top bed system in your reactor which can handle a large … WebIn NHT straight run naphtha is sent to the surge drum where water present in the feed is routed to OWS. Naphtha is sent to reactor section by the charge pumps. Naphtha from charged pumps is combined with hydrogen rich recycle gas from the recycle gas compressor. The combined feed is heated in the charge heater before going to NHT reactor.
WebFeb 22, 2016 · If the fluid flow is up through the catalyst bed then the bed can become fluidized if the pressure drop is high enough to support the weight of the catalyst. Fluidized beds usually have a lower pressure drop than down flow at high flow rates (Towler, 2012). In addition, fluidizing the catalyst eases the transition from one reaction zone to another.
