  • Offgas stream direct contact condenser
    Patent number: 10252957
    Abstract: Methods and systems for the dehydrogenation of hydrocarbons include a direct contact condenser to remove compounds from an offgas process stream. The reduction of compounds can decrease duty on the offgas compressor by removing steam and aromatics from the offgas. The dehydrogenation reaction system can be applicable for reactions such as the dehydrogenation of ethylbenzene to produce styrene, the dehydrogenation of isoamiline to produce isoprene, or the dehydrogenation of n-pentene to produce piperylene.

  • Method for reducing energy consumption in a process to purify styrene monomer
    Patent number: 9902667
    Abstract: An energy conservation process directed to the purification of styrene monomer via distillation after the dehydrogenation reaction of ethylbenzene to produce crude styrene is disclosed. As practiced today, the purification of styrene via distillation requires large amounts of energy (i.e., steam) to provide heat to the various distillation columns. The presently disclosed improved process allows for a reduction in the amount of steam needed for this purpose.
