20090299117 | Diisobutylene process - This invention is a process for producing diisobutylene from isobutylene. The process comprises first contacting a sulfonic acid resin with a reaction feed comprising isobutylene and tertiary butyl alcohol to produce a product stream comprising diisobutylene, isobutylene, tertiary butyl alcohol, and water. The product stream is distilled to produce a first overhead stream comprising water and isobutylene and a first bottoms stream comprising diisobutylene and tertiary butyl alcohol. Water is separated from the first overhead stream, and the resulting isobutylene-enriched stream is recycled back to the reaction step. The first bottoms stream is distilled to produce a second overhead stream comprising tertiary butyl alcohol and a bottoms product stream comprising diisobutylene. | 12-03-2009 |

20100230167 | TENSION/COLLAR/REAMER ASSEMBLIES AND METHODS - The present invention provides drilling assembles and methods that are especially useful for a bottom hole drilling assembly for drilling/reaming/or other operations related to drilling a borehole through an earth formation. In one embodiment, the drilling assembly utilizes standard drill collars which are modified to accept force transfer sections. In another embodiment, the drilling assembly comprises a tension inducing sub which creates a force that may be used to place the bottom hole assembly or portions thereof in tension. In another embodiment, a reaming assembly is held in tension to provide a stiffer reaming assembly. | 09-16-2010 |

20120128578 | System and Method for Extracting and Collecting Substances From a Molecular Combination - A system and process are provided for extracting a substance from a molecular combination. The process comprises heating the molecular combination to dissociate the molecular combination into cations and anions, moving the cations and anions through a magnetic field to separate cations and anions, and isolating cations from anions with a barrier. The system comprises a non-conductive conduit for guiding an ionized particle stream, a magnetic field source for creating a magnetic field through which the ionized particle stream moves, and a barrier located in the conduit. The ionized particle stream has a velocity relative to the conduit, and the magnetic field source is oriented relative to the velocity of the ionized particle stream so that cations are separated from anions as the ionized particle stream moves through the magnetic field. The barrier is oriented in the conduit so that cations are isolated from anions after separation. | 05-24-2012 |
