Aromatic fractionation or BTX filtration involves removing contaminants from extraction solvents like sulfolane.
Aromatic Fractionation is when a refinery utilizes reformate from the catalytic reformer and extracts the aromatics rather than blend them into gasoline. The aromatics are then separated in pure benzene, toluene, and mixed xylenes products at the BTX (benzenetoluene-xylene) Unit. The BTX is then either processed by a chemical unit within the refinery or sold to a chemical facility for production into a wide range of chemicals from solvents, to fibers, films, and plastics.
A key concern in this application is safety of the employees and prevention of exposure to hot toxic substance.
|Filter Solution||Filter Purpose||Filter Benefit|
|LiquiPleat™ Series Pleated Style Liquid Elements and Vessels.||Removes scale and solid contaminants including iron sulfites.||Protects downstream equipment.|
Prevents heat exchanger and tower fouling.
Reduces foaming problems.
|LiquiPleat™ HF Series “High Flow” Pleated Style Liquid Elements and Vessels.||Removes solid particulates from the final product.||Protects coalescers and other downstream equipment. Allows efficient operation of coalescers to remove water from the final product.|
|PhasePUR™ or Phase-LOK™ Series Liquid/Liquid Coalescing Elements and Vessels.||Removes suspended water from the final product.||Maintains sales specification of final product.|
Reduces disposal, maintenance, and reprocessing costs.
The most common filtration problems in aromatic fractionation are foaming and fouling. Solid particulates cause foaming resulting in reduced process flow and the injection of costly foaming inhibitors to regain control. Fouling also occurs from excessive particulate concentrations and reduces operating efficiencies in distillation and recovery towers, heat exchangers, and other downstream equipment. To meet sales quality specifications of BTX products; an optimal filtration system is required to remove both solid and liquid contaminants.
