Case Studies

Upstream Piping

The upstream piping (or isometrics) will always dictate the condition of the flow entering the vessel. Special care should therefore be taken when designing the piping in a gas production system to minimize the risk of maldistribution and avoid the droplet shatter that could reduce the performance of the downstream separation internals. By modelling the isometrics with CFD, maldistribution can be reduced and the size of any droplets entering the separator can be predicted. This is useful for troubleshooting existing vessels and optimising the design of the process internals.
