International Classification:

C12P 7/14

US Classification:

435162, 435 71

Abstract:

Ethanol and other liquid products produced by contacting carbon monoxide (CO) and/or a mixture of CO(carbon dioxide) and H(hydrogen) with a microorganism in a bioreactor are separated using a combination of distillation and vapor permeation membranes. The bioreactor passes an effluent with an ethanol concentration of 1 to 6 wt % to a distillation column that produces an overhead vapor stream enriched in ethanol. A series of vapor permeation membranes retain ethanol as retentate and produce a 99 wt % or higher ethanol product. Ethanol depleted permeate streams flow back to the column and the bioreactor. Coupling a bioreactor with distillation and pervaporation efficiently and economically separates ethanol when present at low concentration in an aqueous fermentation broth. The separation arrangement may also include a flash zone ahead of the distillation column to raise the concentration of the ethanol in the input stream to the distillation column.

H04B 10/073
H04B 10/2581

Abstract:

Methods for estimating the Effective Modal Bandwidth (EMB) of laser optimized Multimode Fiber (MMF) at a specified wavelength, λ, based on the measured EMB at a first reference measurement wavelength, λ. In these methods the Differential Mode Delay (DMD) of a MMF is measured and the Effective Modal Bandwidth (EMB) is computed at a first measurement wavelength. By extracting signal features such as centroids, peak power, pulse widths, and skews, as described in this disclosure, the EMB can be estimated at a second specified wavelength with different degrees of accuracy. The first method estimates the EMB at the second specified wavelength based on measurements at the reference wavelength. The second method predicts if the EMB at the second specified wavelength is equal or greater than a specified bandwidth limit.
