Summary on Grant Application Form |

Process intensification of oil-water-gas separations on offshore platforms will necessitate downsizing or removal of big separation vessels. As unit operations achieving the same separation are smaller, proportionately larger processing time is spent in pipelines. Consequently, the effect of pipelines and fittings on the state of multiphase flow is of fundamental importance. Certainly pipelines and fittings on the state of multiphase flow is of fundamental importance. Certainly, pipelines and fittings must be designed to minimise re-dispersion effects, and even contribute to separation if well integrated. Although some aspects of the effects of pipes and fittings are known from experiment, there is insufficient knowledge for use as a design tool. Specifically, the effects on coalescence of adverse local pressure gradients (expansions), inclination and swirling flow (cyclonic devices) are unstudied. This project gathers experimental, computational, and modelling expertise from three leading centres on multiphase flow and pipe systems for a concerted programme to establish design tools and guidelines for the kinetics of coalescence.The project will develop macroscale CFD simulations and microscale sub-grid models based on molecular dynamics-like simulations. These models will be validated by extensive experimental databases gathered on kinetics of dispersion break down and coalescence on large scale multiphase flow rigs (with and without solids loading) and separately in a small scale high-gee cell.
