| 20130071309 | SEPARATION OF GASES - Aspects of the disclosure relate to the separation of gases and to a process for the removal of carbon dioxide gas using liquid absorbents. | 03-21-2013 |
| 20130044211 | SYSTEM FOR MEASURING A MULTIPHASE FLOW - System for measuring a multiphase flow ( | 02-21-2013 |
| 20120303281 | ENHANCED DYNAMIC WELL MODEL FOR RESERVOIR PRESSURE DETERMINATION - A computer implemented method for determining reservoir pressure in a shut-in well, the method comprising: determining the initial physical characteristics of the well; determining properties of gas bubble throughout the well; calculating a dynamic mass transfer rate for the gas bubble over a period of time; calculating the physical fluid movement along the well: calculating a rate of fluid influx from the reservoir; determining a corrected pressure gradient along at least part, or all, of the profile of the well using the determined dynamic mass transfer rate, fluid movement and rate of fluid influx; and determining the reservoir pressure from a measure, or determination, of the well head pressure and the calculated pressure. | 11-29-2012 |
| 20120108822 | Process For The Preparation Of Chalcogene Compounds - The present invention is a novel process for the preparation of chalcogenone compounds by conversion of ionic liquids and salts comprising nitrogen-containing heterocyclic cations and basic anions to the corresponding nitrogen-containing heterocyclic chalcogenones by reaction with elemental chalcogens. | 05-03-2012 |
| 20100276821 | VAPOR DISTRIBUTOR FOR GAS-LIQUID CONTACTING COLUMNS - A vapor distributor for use in atmospheric or vacuum columns includes a new design of vapor inlet device, or vapor horn, to provide superior mixing and distribution of a tangential first feed and a vertical second feed. New vapor inlet device has an inlet dividing the first feed into two portions, each flowing in respective housings in opposed circulation directions, and a plurality of vanes for redirection of vapor. Mixing and distribution of feeds by the vapor distributor is further enhanced by inclusion in vapor distributor of a mixer and vapor directing plates. | 11-04-2010 |
