Continuous aromatization and catalyst regeneration device and method thereof

ActiveCN101244969ANo temperature fluctuationsDoes not affect aromatization reactionMolecular sieve catalystsCatalyst regeneration/reactivationFluidized bedAromatization
The invention discloses and belongs to the chemical equipment field, which more particularly relates to a C1-C2 hydrocarbon or methanol aromatization and catalyst regeneration fluidized bed device (comprising an aromatization fluidized bed, a catalyst continuous regeneration fluidized bed, a pipeline used for catalyst transportation and a solid transportation device which are arranged between the two fluidized beds), and an aromatization catalyst which is suitable for the fluidized bed operations and the operation methods of aromatization reaction, catalyst regeneration and the device. The device, the catalyst and the method are used for regulating the coking status of the catalyst in an aromatization reactor at any time, thus achieving the aim of transforming the C1-C2 hydrocarbon or the methanol continuously and efficiently and generating aromatics with high selectivity. The C1-C2 hydrocarbon or methanol aromatization and catalyst regeneration fluidized bed device of the invention with adjustable catalyst activity and selectivity can improve the purity and yield of the aromatics, can lead the aromatization reactor operates continuously without stopping at the same time, can improve the strength of aromatics production, and lower the operation cost of the catalyst regeneration when stopping and restarting the whole system.

InactiveUS6968295B1Lower maintenance costImprove system efficiency and performanceThermometer detailsLevel controlWeather dataEnergy cost
A method of and system for auditing the energy-usage by a facility, where the facility includes an energy-using system having an operating parameter with a value. One embodiment of the method includes acquiring an initial value of the operating parameter, acquiring initial data of the energy-using system with the operating parameter set at the initial value, acquiring values relating to a weather parameter for the facility, and creating a baseline model of the energy-usage by the facility with the initial energy-using system data and the weather data. Some embodiments of the method can further include determining an initial rate of energy-usage by the facility based upon the baseline energy model, changing the initial value of the operating parameter, determining a modified rate of energy-usage by the facility, and calculating a savings in energy costs from changing the initial value of the operating parameter.

Aqueous treatment apparatus utilizing precursor materials and ultrasonics to generate customized oxidation-reduction-reactant chemistry environments in electrochemical cells and/or similar devices

An electrochlorination and electrochemical system for the on-site generation and treatment of municipal water supplies and other reservoirs of water, by using a custom mixed oxidant and mixed reductant generating system for the enhanced destruction of water borne contaminants by creating custom oxidation-reduction-reactant chemistries with real time monitoring. A range of chemical precursors are provided that when acted upon in an electrochemical cell either create an enhanced oxidation, or reduction environment for the destruction or control of contaminants. Chemical agents that can be used to control standard water quality parameters such as total hardness, total alkalinity, pH, total dissolved solids, and the like are introduced via the chemical precursor injection subsystem infrequently or in real time based on sensor inputs and controller set points.

Computer implemented system and method for the generation of data access applications

A method and architecture is described that discovers software application metadata and generates data access applications based on the discovered software application metadata. The discovered metadata along with handcrafted metadata goes through a discovery process and is converted into common, generic abstract metadata objects. The abstract metadata objects then go through an instantiation process to be translated into concrete metadata objects that represent the unique configuration, context and terminology of the source software application. The concrete metadata objects can be generated into numerous forms for the purposes of data access and information sharing. The system also has upgrade protection.
