Abstract: A system for automatically modifying the lean of a catamaran during a turn includes a pair of fins, each substantially permanently affixed to the inside edge of the left and right hull, plus a pair of vertically displacing plates that extend, one at a time, from the left or right hull, into the body of water. Individually, the fins or plates modify the lean of a catamaran during a turn such that the tilt is neutral or inboard, versus outboard without either. The cumulative effect of using both is substantial and synergistic.

Abstract: Methods, systems, and computer-readable media for developing, storing, validating, tracking and transferring stored procedures are presented. The stored procedures may be stored in a central storage location. The storage location may receive a first version of a stored procedure and generate a change identifier for the first version. The system may evaluate the stored procedure to determine whether it complies with standards of the entity. In some examples, the first version may be checked-out and transferred to another environment for, for instance, modification to create a second version. The second version may then be transmitted to the central storage location for storage. A second change identifier may be generated and associate with the second version. The second version and the second change identifier may be stored. Similarly, an unlimited number of modifications to the stored procedure, each associated with a unique change identifier from the storage system, may be made.

Abstract: A process for producing cyclohexane by benzene hydrogenation using a hydrogen source that contains impurities, such as carbon monoxide and/or light hydrocarbons, wherein a supported catalyst reduces benzene to cyclohexane and carbon monoxide to methane and water. Alkenes, such as ethylene, are also reduced to their alkane counterparts. Under the disclosed operating conditions, the process proceeds without deactivation of the catalyst, and without the formation of a significant amount of cracking products, such as methylcyclopentane.

Abstract: A method for removing diethylhydroxylamine (DEHA) from butadiene streams that does not leave an excessive amount of residual contaminates in the isolated butadiene stream. The DEHA is removed from the butadiene streams by ion exchange resins, which efficiently remove DEHA from the butadiene streams without causing the accumulation of an excessive amount of residual contaminants. To prevent polymerization of the butadiene upon removal of the DEHA, tert-butylcatechol (TBC) may be added to the butadiene stream before or after DEHA removal. Fresh or spent ion exchange resins may be used. After removal from the butadiene stream, the isolated DEHA can then be easily concentrated, and disposed or recycled. A method for removing DEHA from hydrocarbon streams is also disclosed.
