The Effect Of Scale On Spray Nozzle Performance, Aaron M. Joness

Electronic Thesis and Dissertation Repository

In the petroleum industry, Fluid Coker^TM are used to upgrade the heaviest remains of heavy oil into useful lighter products such as fuel oil or petrochemical feed. The development of a better injection into a Fluid Coker^TM is a key parameter to obtain a more efficient and sustainable use of heavy crude oil. The main detrimental factor in Fluid Coking^TM is the formation of agglomerates between the injected oil and the coke particles. These agglomerates not only trap injected oil, not allowing free reaction, but also cause harm to the Coker^TM when they fall to the …

Liquid Distribution From Industrial Scale Spray Jets In Fluidized Beds, Mohammadali Zirgachianzadeh

Electronic Thesis and Dissertation Repository

Liquid injections via spray nozzles are used in fluidized bed reactors such as Fluid Cokers. In such industrial processes, in order to maximize the product yields it is required to optimize the performance of the nozzle. Moreover parts of the bed might become defluidized, bogged, due to high liquid load. Then optimizing the performance of the nozzle and local bed bogging detection is the primary research objectives for this thesis work.

The first part of the research work was focused on developing a novel method employing electrical conductance to characterize the liquid distribution in a large scale fluid bed of …
