  • Spectroscopic analysis and control
    Patent number: 9625373
    Abstract: Apparatus for spectroscopic analysis which includes a tunable diode laser spectrometer having a digital output signal and a digital computer for receiving the digital output signal from the spectrometer, the digital computer programmed to process the digital output signal using a multivariate regression algorithm. In addition, a spectroscopic method of analysis using such apparatus. Finally, a method for controlling an ethylene cracker hydrogenator.
    Type: Grant

  • Methods for making ethanolamine(s) and ethyleneamine(s) from ethylene oxide and ammonia, and related methods
    Patent number: 8383861
    Abstract: The present invention relates to processes for the manufacture of one or more ethanolamines and one or more ethyleneamines starting from the reaction of ethylene oxide with ammonia to produce one or more ethanolamines and the conversion of the ethanolamine(s) to ethyleneamine(s). The present invention also relates to separating alkylethyleneamines from ethyleneamines.

  • Nanoscale polymerized hydrocarbon particles and methods of making and using such particles
    Publication number: 20040054111
    Abstract: This invention is cross-linked, polymerized hydrocarbon particles which composition is characterized in that the particles have an average diameter of less than 30 nm, the particles exhibit a volume swell factor of no greater than 3.0; the composition is essentially free of metal ions; the particles have a polydispersity (polystyrene relative Mw/Mn) of less than 3.0, and the particles are characterized by a Mark-Houwink plot having a slope with an absolute value of less than 0.4 for the peak molecular weight range. The invention is also a method of making nanoparticles having a weight average diameter less than 30 nm by emulsion polymerization in the substantial absence of ionic components. Finally, the invention is a method of using such particles as thermally degradable components in making porous films.
