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 کاملOptimization of velocity for energy saving and mitigating fouling in a crude oil preheat train with fixed network structure
Fouling of the inside of tubes in crude oil preheat systems increases pressure drop and pumping costs. In this paper, a method is proposed for optimizing crude oil velocity to reduce fouling of the heat exchanger tubes thereby maintaining heat transfer rates and reducing pressure drop. A simulated annealing algorithm is proposed to describe and optimize the interactions between heat transfer, p...
متن کاملSimultaneous 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...
