Simultaneous Consideration of Flow and Thermal Effects of Fouling in Crude Oil Preheat Trains
Given models linking flow resistance and fouling resistance it becomes possible to simulate the effects of fouling on the hydraulic performance of a refinery pre-heat train. Such a simulation has been used here to identify when plant throughput will be limited by pressure drop; how throughput can be improved through the cleaning of individual exchangers and groups of exchangers; and how much pr...
متن کاملinvestigation of crude oil fouling on performance of preheat exchangers of crude distillation unit (cdu)
in this article the effect of fouling on tube side and the overall performance of preheat exchangers of crude distillation unit of petroleum refinery have been investigated. for this purpose the experimental data of australian light crude oil in surface temperature of 200-260oc and the velocity between 0.25 to 0.4 m/s have been used. first, an overall dirty heat transfer coefficient was calcula...
متن کاملan application of equilibrium model for crude oil tanker ships insurance futures in iran
با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...
Application of Threshold Model with Various Tube Wall Temperatures for Crude Oil Preheat Train Fouling
The Propose of this paper is to introduce a new model for crude oil fouling in preheat trains of crude distillation unit. The experimental results of Australian light crude oil with the tube side surface temperatures between 200-260 oC and fluid velocity ranged 0.25 to 0.4m/s were used. The activation energy of chemical reaction depends on the surface temperature has been calcula...
متن کاملNeural Network Controller for a Crude Oil Distillation Column
The development of neural network that could be used for the control of an industrial process is discussed. Field data from a working distillation column or fractionator of crude oil refinery in Nigeria was used for the development and testing the effectiveness of the controller. The developed controller performed optimally when compared with the installed distributed control system based on pr...
