PREDICTING DROPLET POPULATIONS IN PIPING FLOWS

摘要

Disclosed is a method to predict evolution of the distribution of droplets injected into a fluid in a process pipe; and model the scrubbing of fluids that contains contaminant gases with aqueous scrubbing agents. The method is implemented using processor that: receives information corresponding to a process fluid and a piping infrastructure in which the process fluid flows; receives information corresponding to an injectant and an injector that injects the injectant into the process fluid; and predicts a droplet size distribution as a function of time. The model computes the scrubbing rate as a function of time, correlating with the concentration of the contaminants to be scrubbed, providing a prediction of the contaminant concentration at any given distance from the injector. The prediction is based at least in part on computation of one or more closed-form expressions that describes the droplet interaction processes as well as the scrubbing rate.
