Patent CA-2774369-A1 (CA)
Inventor: GRUBB SCOTT A
IPC: G01B17/02
Filed: 2010-09-17
Abstract: The invention relates to very precisely measuring changes in thickness of pipe walls to determine corrosion rate prior to any significant corrosion loss. The thickness is determined by ultrasonic testing where many measurements of the wall thickness are taken at the same spot by a fixed sensor and errors associated with noise and temperature changes are substantially eliminated. A highly sensitive receiver converts each reflected pulse to waves that are averaged with other pulse measurements. The resulting average wave is analyzed so that each waveform is analyzed to identify the extrema and inflection points of each reflected pulse. The resulting analysis provides a far more accurate determination of the time between reflected pulses. As a result, a far more accurate picture of corrosion at the location of the wall of the pipe can be determined within weeks with a high degree of confidence.

Abstract: This present invention provides a method to more efficiently recover hydrogen and carbon dioxide, preferably at least 50%, even more preferably at least 75%, and most preferably at least 90% of the carbon dioxide. The present invention further provides the design for capture of at least 80%, carbon dioxide from syngas that allows for the simultaneous production of medium to high amounts of hydrogen in the syngas as a part of the production of hydrogen in a hydrogen generation plant. By using the process of the present invention, especially in terms of a hydrogen generation plant, it is possible to increase recovery of hydrogen and capture of the carbon dioxide in the syngas stream by balancing the recycle of the hydrogen rich permeate from the hydrogen membrane separation units to the process unit and/or the water gas shift as capacity allows when a carbon dioxide separation unit, a carbon dioxide membrane separation unit and two hydrogen membrane separation units are utilized.

Title: Mass polymerization of (meth)acrylate co-polymers which are soluble in aqueous alkaline
Inventor: POPPE DIRK
IPC: C08F220/26
Filed: 2010-10-07
Abstract: The invention relates to the synthesis of (meth)acrylate-based mass polymers which are soluble in aqueous alkaline. The invention in particular relates to the synthesis of polymers by means of a mass polymerization. Said mass polymers have a significantly improved solubility in aqueous alkaline media over corresponding polymers produced by means of a heterogeneous aqueous polymerization method, such as emulsion or suspension polymerization. Improved solubility in said context refers to the dissolution rate being faster among particles of equal size, to no significant turbidity remaining after dissolution and to the viscosity of the obtained solutions being lower at the identical ratio of solids content. Furthermore, the compatibility of the compounds according to the invention with water-based varnishes is at least comparable or even improved.
