Are you planning to “wash” a catalyst bed in a reactor and need to monitor process conditions?

Using Tru-Scan™ technology to detect liquid levels in pressure vessels and catalyst levels in reactors is a fast and extremely reliable measurement performed online. One of the problems operations staff faced when planning a catalyst “wash” was not having an indication of any accumulated liquid level in the bottom of the vessel to monitor the procedure. Read more on how Tracerco was able to assist a customer with monitoring the liquid level throughout their planned wash campaign.

One category of special applications is liquid-liquid extractors. Besides the fact that liquid-liquid extractors are not “typical” distillation or fractionation unit operations, what makes them a special application for Tru-Scans™? The source and detector system that is used in scanning measures density changes of the process materials inside the tower. With a typical fractionation tower there is a large density difference between the vapour and liquid phases. Thus there is a large density range between clear vapour and clear liquid to detect process or operating conditions existing in a typical fractionation tower – entrainment, foaming, flooding, internal damage, etc. But liquid-liquid extractors are liquid full, with no large vapour-liquid density difference. Meaningful scan results from a liquid-liquid tower rely on the density difference between the two liquid phases being significant enough to distinguish as some extraction processes involve two liquids that have comparable densities.
