โœฆ Synopsis

Information gained on hydrate formation on a sin@. rising bubble of hydrocarbon gas is applied to the case of a complete bubble plume. When hydrate formation is inch&d in the plume equations there is a strong coupling between small scale bubble behaviour and the total plume buoyancy. The sensitivity of the plume solutions to this coupling is examined for methane and a r&m-al gas typical of certain Arctic oilwells. The results of the latter are applied to a hypothetical oilwell blowout under Arctic conditions, and indicate that for wellhead depths greater than 800 m all the gas will be converted to hydrate before tbe surface is reached.

## Abstract In this paper a CFD model for a bubble column reactor undergoing a first order reaction A โ†’ B is developed. The reactor operates in the homogeneous bubbly regime and has a diameter __D__~T~ = 1 m and height __H__~T~ = 5 m. The incoming gas stream contains inerts, varying in proportion f

number of authors have on the basis of experiments determined that pressure and gas density can have an influence on bubble formation size. Usually this influence is attributed to the gas momentum force, generated by gas flowing into the bubble during its formation. In this article the theoretical b
