His innovative approaches aim to enhance product purity while reducing energy consumption.

Latest Patents

One of Zvi Merchav's latest patents is an "Apparatus and process for improved aromatic extraction from gasoline." This invention utilizes a glycol solvent-based extraction process that decreases liquid-vapor flashing and reduces reflux flow rates. It also cleverly uses heat of enthalpy produced at one point as a source of energy at another point, significantly increasing the purity and amount of product obtained while decreasing energy consumption.

Another significant patent is the "Method for removing ethylbenzene from a para-xylene feed stream." This method involves a reactor unit used in a pretreatment step, containing an isomerization catalyst that converts ethylbenzene in the feed stream to benzene. The converted benzene is then removed from the stream before it undergoes cyclic treatments by a para-xylene separator and an isomerization unit.
