  • Alkylene oxide purification processes and systems
    Patent number: 8845863
    Abstract: Processes and systems for purifying ethylene oxide, including introducing a feed stream including ethylene oxide to a heat exchanger to heat the feed stream, feeding the heated feed stream to a distillation apparatus base below a first stage, removing from the distillation apparatus an impurity fraction as a top exit stream from the distillation apparatus located at a top take-off on the distillation apparatus, removing from the distillation apparatus an ethylene oxide stream of 99.7 weight percent purity, based on the total weight of the ethylene oxide stream, from the distillation apparatus, and removing from the distillation apparatus an aldehyde enriched fraction as a bottom stream from the distillation apparatus, where the aldehyde enriched fraction is fed directly to a glycol reactor.

  • Dual pressure recovery boiler
    Patent number: 7243619
    Abstract: A dual pressure boiler system has a bottom furnace that operates as a low pressure natural circulation steam generating system and a top furnace that operates as a high pressure natural circulation steam generating system. The low pressure natural circulation steam generating system has a low pressure steam drum, a first pump for providing feed water to the low pressure steam drum, and a low pressure superheater fluidly connected to the low pressure steam drum. The high pressure natural circulation steam generating system has a high pressure steam drum, a second pump for providing feed water to the high pressure steam drum, and a high pressure superheater fluidly connected to the high pressure steam drum.
