This raised the question: could losing the valve float have promoted flood? We applied the Fluor Multipass Maldistribution Model (MMM) to see whether these observations can be modelled. In a previous article, we applied the same model to discover multiple steady state vapor/liquid distributions in 2-pass moving valve trays at turndown.
Our analysis shows that uneven or complete float removal on the trays can channel the vapor and liquid in different directions, which may account for the premature flood and above observations.
