摘要:
Low dosage naphthenate inhibitors, such as a surfactant or hydrotrope, delivered into production fluids for contact with mixtures of oil and water, such as in a hydrocarbon producing formation, production equipment, or processing systems. Inhibitor compounds such as monophosphate esters and diphosphate esters exhibit surface-active properties that cause the inhibitors to self-associate at oil-water interfaces and inhibit interactions between organic acids in the oil with cations or cation complexes in the water. These compounds also inhibit aggregation of organic acid carboxylate salts that form when pH and pressure conditions are amenable to organic acid ionization. Preferred inhibitors do not form emulsions due to the formation of unstable mixed interface structures that result in coalescence of dispersed droplets. Naphthenate inhibitor compound dosages of less than 100 ppm can effectively inhibit naphthenate salts or other organic acid salts that can form precipitates or emulsions during crude oil production or processing.
摘要:
Inhibiting naphthenate salts that can form precipitates or emulsions during crude oil production or processing. An effective amount of a naphthenate inhibitor, such as a hydrotrope, is provided into the production fluids for contact with mixtures of oil and water in the formation, the production equipment, or processing systems. It is believed that the naphthenate inhibitors, such as monophosphate ester or diphosphate ester, exhibit surface-active properties that cause the inhibitors to align and concentrate in a layer at the oil-water interface and thereby prevent interactions between organic acids in the oil phase with cations or cation complexes in the water. It is believed that the physical positioning and geometry of the naphthenate inhibitor blocks the growth of naphthenate salt crystals. However, it is preferred that the naphthenate inhibitors also avoid the formation of oil-in-water and water-in-oil emulsions.

A new and distinct hybrid of the genus Caesalpinia is provided. This hybrid has been named ‘Mnstamepa’ for a cultivar name and is trademarked as Sierra Sun™. The new variety is a product of a cross between Caesalpinia mexicana and Caesalpinia palmeri which occurred in the year 1996. The Genus/species designation for the plant is Caesalpinia mexicana×palmer. The new variety was selected because it displays a uniquely different flower color previously unavailable in the genus, and a more open less twiggy habit with a finer leaf structure that either of its parents.

An apparatus bounds and retains the medium in which a transplantable plant is grown, and promotes the production of lateral root tips by such a plant at all levels in the growth medium. The apparatus includes a sheet having a plurality of hollow protuberances formed with proximal protuberance openings that communicate with distal protuberance openings. The protuberances provide pathways that mimic the natural tendency of the plant roots, so as to decrease the likelihood of the root tips evading the protuberances and promote root-tip growth towards the distal protuberance openings whereby air-root pruning is assured.

Electrochemical apparatus and methods that support periodic, non-steady state, or discontinuous operation without suffering degradation of materials or loss of efficiency. The invention provides a means for positioning one or more electrodes into contact with electrolyte and means for retracting the one or more electrodes out of contact with the electrolyte. The means for positioning and means for retracting may be the same device or different devices. The means for positioning and means for retracting may be designed to provide automatic, passive, or fail-safe retraction of the electrode upon a given shutdown condition, such as a voltage of less than one Volt being applied between the first and second electrodes, expiration of a time period, an ozone concentration greater than a setpoint ozone concentration, contact pressure of less than 5 psig, and combinations thereof.

A method for preparing and automatically updating a greeting on a voice mail system comprising receiving a call to a voice mailbox, selecting a greeting template based on one or more conditions, identifying greeting parameters present within the greeting template, retrieving values for the greeting parameters, and generating a greeting using the values of the greeting parameters in accordance with the greeting template. The method allows the voice mailbox user to better manage incoming calls when the user is not available to accept them. The method further provides a benefit to the caller by providing a greeting that contains information tailored to benefit the caller, thereby helping the caller to decide, for example, whether or not to leave a voice mail message in the user's voice mailbox.
摘要:
An apparatus to align and dock or undock a first electronic circuit board with a first connector with a second electronic circuit board with a second connector. The apparatus comprises a guide plate with a linkage to connect to a mounting plate. The first electronic circuit board is secured to the mounting plate. The guide plate is inserted into a chassis comprising a guide to receive the guide plate. The guide aligns the first connector to be received in the second connector. The linkage is actuated by displacing a positioning handle. The linkage translates the motion in a direction generally perpendicular to the direction of displacement of the positioning handle. The mounting plate is translated in the generally perpendicular direction, and the first connector is received into the second connector. The operation may be reversed to remove the first connector from the second connector.

The present invention discloses a system and method for delegated page specialization based on a page layer concept. A page consist of a set of layers. Except the first layer each layer represents a delta (container, frames) in its layout to its previous layer introduced on the corresponding level of administration. Administrators can modify the previous layers by defining new immutable and optional containers or frames on the page (delta). Only the deltas to the previous layers are stored with assignments to their parent layers. Immutable containers or frames of previous layers cannot be modified. The final page is automatically constructed as an union of deltas being stored in a so called tree-structure. The delegated page specialization is preferably accomplished via a GUI-component which supports the administrators.
摘要:
A method for the anodic electrochemical synthesis of ammonia gas. The method comprises providing an electrolyte between an anode and a cathode, providing nitrogen and hydrogen gases to the cathode, oxidizing negatively charged nitrogen-containing species and negatively charged hydrogen-containing species present in the electrolyte at the anode to form adsorbed nitrogen species and adsorbed hydrogen species, respectively, and reacting the adsorbed nitrogen species with the adsorbed hydrogen species to form ammonia. Nitrogen and hydrogen gases may be provided through a porous cathode substrate. The negatively charged nitrogen-containing species in the electrolyte may be produced by reducing nitrogen gas at the cathode and/or by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte. Similarly, the negatively charged hydrogen-containing species in the electrolyte may be produced by reducing hydrogen gas at the cathode and/or by supplying a hydrogen-containing salt, such as lithium hydride, into the molten salt electrolyte.
