Latest Patents
Sardina's latest patents include a process for the manufacture of alkylbenzenes. This innovative method involves reacting a feed of fresh and recycled benzene with fresh olefin in the presence of an alkylation catalyst within an alkylator that has at least two reaction stages. Each stage operates adiabatically, ensuring that essentially all of the olefin is completely reacted. The preferred alkylbenzenes produced by this process are ethylbenzene and cumene. Another significant patent is for a dehydrogenation process for the production of styrene from ethylbenzene. This improved process utilizes steam at elevated temperatures and recovers heat of condensation that is typically lost during the separation of components in the dehydrogenation reaction effluent. This innovation enhances efficiency by eliminating the need for a compressor and allows for the vaporization of an aqueous feed mixture of ethylbenzene and dilution water.
