Abstract Internal cyclones use diplegs to recycle solids the dense fluidized bed in most industrial beds. Poor dipleg operation can greatly increase particle losses from cyclones. Experiments with a 0.6 m diameter column and large group A particles showed that at low gas velocities bed, slugs rose through dipleg, causing emission of pulses; this issue was resolved by adding an elbow termination bottom dipleg. At high velocities, backed up. new model backup resulted pressure fluctuations near...
Abstract The stripper section of a fluid‐coker consists system baffles (sheds) that enhances the removal efficiency entrained and adsorbed hydrocarbons from fluidised coke‐particles. If particles contain thin liquid film layer heavy hydrocarbons, making them excessively ‘wet’ or ‘sticky’, if they stay in contact with sheds for too long, solid deposits are formed lead to fouling. Extensive fouling decreases stripping product yield can shorten run‐times between shutdowns. Because fouling,...
A FS launcher is being designed for the ITER upper port, which offers enhanced physics performance over RS launcher. two mirror system used to decouple focusing and steering aspects of provide a relatively small beam waist (<20 mm) projected far into plasma (>1.6 m from mirror). The resulting NTM stabilization efficiency (maximum CD density divided by local bootstrap current >1.6) above marginal q = 2 3/2 rational flux surfaces relevent equilibria (scenarios 2, 3a 5) factor ∼3 relative an...
Abstract Intermediate pyrolysis reactors are preferred for processes focused on the production of high‐quality biochar. The main types rotary drums, augers, and moving beds agitated with either grates or paddles. These usually operated in continuous mode, designed to provide a pure, homogeneous biochar product by ensuring near plug flow reacting particles. There is need laboratory that can enough testing applications such as soil amendment, fillers concrete polymers, coke substitution,...
Abstract Fluid coking is a process that upgrades heavy oil. In fluid coker, oil sprayed into fluidized bed of hot coke particles, where it undergoes thermal cracking. The formation wet agglomerates, caused by poor contacting between the and slows cracking leads to operating problems. product vapours exiting coker are scrubbed condense heavier components, which recycled coker. recycle stream contains unwanted suspended fines could affect interaction liquid feed resulting agglomerate...
Abstract Liquid injection into a gas–solid fluidized bed has been applied in various industries, such as coating and granulation processes pharmaceutical food reactor cooling polyolefin production, fluid catalytic cracking, coking the petroleum industry. A new experimental method successfully developed to monitor vaporization rate of liquid injected bed. In addition, it can be used determine mass accumulated at steady state. With this method, measurements have identified three phenomena that...
Abstract Formation of agglomerates in fluidized beds can cause operating problems, such as excessive stripper shed fouling, which lead to premature unit shut down. The focus this study is reach a better understanding how move through bed improve the Fluid Cokers and minimize risk reaching regions where they problems. Two experimental methods were used: first, Gum Arabic binder solution was injected into two‐dimensional (2D) under conditions that simulate agglomerate formation Cokers, mass...
Abstract Biochar is a valuable product of pyrolysis. A new rotating heater pyrolysis reactor (RHP) was developed to process variety biomass feedstocks up 30 L and produce biochar batches several kilograms. The RHP design simple, allowing for easy construction, low‐cost operation, low energy consumption. produced from softwood woodchip in the 2–3 h determined have physical chemical properties comparable conventional batch at temperatures between 375–425°C.
The capability of any given e.m.‐wave plasma heating system to be utilized for physics applications depends strongly on the technical properties launching antenna (or launcher). An effective ECH launcher must project a small mm‐wave beam spot size far into and ‘steer’ across large fraction cross section (along resonance surface). Thus choice in concept design may either severely limit or enhance effectively applied applications, such as sawtooth stabilization, control Neoclassical Tearing...
