Websuch process, the feed-effluent heat exchanger/reactor system. The apparatus is fairly simple and is safe to operate, and the investment in process equipment and instrumentation is modest. A HOI Pn:bealed reactor Cold feed 118 feed 1 I effluent 111 Reactor ~ II ~ ~ Cooled B Qin Cold feed Preheated feed reactor effluent Qoot Reactor Hot reactor WebThis substantially reduced the reactor effluent temperature. Hence, the feed preheat was also substantially reduced by 15-25°C. The fired heater has been designed to handle vapour feed but, as a result of the reduction in feed preheat, the heater was forced to accept mixed feed (vapour and liquid). The liquid, once exposed to high heat flux on ...
WebThe feed effluent heat exchanger described in embodiments herein can be a gas-gas heat exchanger of a shell and tube type construction wherein a low temperature feed at 20° C.-100° C. is fed to the shell side and the high temperature effluent (e.g., 400° C.-600° C.) is fed to the tube side. WebThe naphtha feed enters the hydrotreatment unit through a charge pump. It is first mixed with hydrogen gas from either the catalytic reforming unit (CRU) or refinery hydrogen …
WebMay 1, 2014 · In this case, the temperature controller is tuned for heater response in the “minute” domain, but the feed-effluent feedback loop can be in the “hour” domain, which often results in large sustained temperature oscillations after an initial disturbance, such as an abrupt change in charge rate or to a more exothermic hydrotreater feed. WebNonetheless, the effectiveness of having a feed filter will depend on the relative size of particles to feed filter mesh size (microns). FeS particles can be as small as 5 microns, and not all may be captured by a typical feed filter. Salts Effluent side fouling in F/E exchangers is typically caused by ammonium sulphides.
