Molecular Sieves are zeolites (metal aluminosilicates) that are extensively used for drying various fluid streams industrially. They are tailored with precise pore size, and work based on size exclusion, adsorbing only those molecules, which can be fit in the pores. Depending on the pore size, applications can range from drying of unsaturated hydrocarbon streams to separation of normal paraffins from cyclic/branched ones. In this work, we have come up with a novel and easy to implement method to check the quality of molecular sieves before loading a new batch in the reactor. Since tons of these molecular sieves are loaded in the reactors, quality has to be checked beforehand. Any issue with the quality of these materials can be detrimental to the operational efficiency of the drying process, leading to the loss of time and money, if it surfaces after loading the molecular sieves in the reactor. Therefore, it is imperative to have a quality check each time a new batch of molecular sieves is loaded.
