摘要： A dry, regenerable solid oxide process directed to convert SO.sub.x from the flue gas stream from a power plant, a coal or oil-fired plant or process heat furnace, or an FCC regenerator to elemental sulfur without using a Claus unit, a hydrogen plant, a regeneration gas separation system, or a hydrogenation section. This dry, regenerable solid oxide process is also effective on Claus plant tail-gas. This process uses solid oxides, such as, for example, magnesium aluminates or spinels to remove sulfur oxides from flue gas streams. The solid oxide is then regenerated by a reducing gas to release the sulfur compounds contained on the solid oxide to produce a gas stream comprising hydrogen sulfide, sulfur oxides and elemental sulfur. The elemental sulfur is then condensed and recovered as a product and the resulting gas stream may be recycled to be reprocessed over the solid oxide.
摘要翻译：一种干式可再生固体氧化物工艺，其特征是将SO x从来自发电厂，煤或燃油电厂或工艺加热炉或FCC再生器的烟道气转化为元素硫，而不使用克劳斯单元，氢厂，再生气体分离系统或氢化部。这种干式可再生固体氧化物工艺对克劳斯植物尾气也是有效的。该方法使用固体氧化物，例如铝酸镁或尖晶石从烟道气流中除去硫氧化物。然后通过还原气体再生固体氧化物以释放固体氧化物上所含的硫化合物，以产生包含硫化氢，硫氧化物和元素硫的气流。然后将元素硫冷凝并回收，作为产物，所得气流可以再循环以在固体氧化物上再处理。

摘要： There is provided a process directed to the use of gases containing or mixed with carbon monoxide, such as synthesis gas, to aid in the regeneration of sulfur oxide-sorbed solid oxides, such as magnesium aluminates or spinels. This process is especially useful in applications where the solid oxide is used to purify the flue gas stream from an FCC regenerator, coal or oil-fired plant, power plant or process heat furnace, or the tail gas from a Claus plant. The process is also useful to remove sulfur oxides from flue gases produced in solid fuel combusters. According to this invention, carbon monoxide may be used alone or in combination with other gases to make the regeneration of the solid oxide exothermic or less endothermic, thereby improving the effectiveness of the regeneration.

摘要： A multi-bed process of removing sulfur oxides and/or other combustible sulfur-containing compounds from a gas stream including combusting the other combustible sulfur-compounds when present in the gas stream with air or oxygen to convert such sulfur-containing compounds to sulfur oxide and form a sulfur oxide enriched gas stream. The sulfur oxide enriched gas stream is contacted with first and second serially connected solid adsorbent beds for adsorbing the sulfur oxides in the form of inorganic sulfates and/or sulfur oxides. A third adsorbent bed is contacted with a reducing gas stream to regenerate the bed by reducing the retained inorganic sulfates and/or sulfur oxides to hydrogen sulfide and/or sulfur dioxide, to thereby form a hydrogen sulfide and/or sulfur dioxide bearing stream. The feeds to each of the beds are realigned to place the second and third beds in series with the sulfur oxide and/or sulfur dioxide enriched stream being fed to the second bed and to place the first bed in a regenerative mode. Thereafter, the foregoing steps are repeated whereby each of the three beds are sequentially placed in an initial bed mode in the series, a regenerative mode, and a second bed mode in the series.

摘要： A method and apparatus for investigating earth formations surrounding a borehole operates by selectively heating a region of the formations, and measuring the thermal response to obtain useful information concerning the characteristic length scales of the pores in the heated region. The thermal response is obtained indirectly by measuring the electrical conductivity response. The invention can be utilized to obtain, inter alia, indications of porosity, permeability, and the distribution of pore geometries. In accordance with an embodiment of the method of the invention, the following steps are performed: heating a region of the formations with a series of pulses of microwave electromagnetic energy; measuring the conductivity characteristic of the region which result from the heating pulses; and determining a property of the region of the formations from the measured conductivity characteristic. In the preferred embodiment of the invention, the conductivity characteristic is converted to conductivity as a function of frequency, and the desired property is determined from the conductivity as a function of frequency. The disclosed technique can also be used for studying the microgeometry of media such as core samples.

摘要： An automated seed package identification apparatus is presented that may include a sensor device configured to read a machine-readable package identifier on a seed package which identifies the seed package and/or the seeds therein. A sensor positioning mechanism adjusts the position of the sensor device with respect to a seed tray assembly which is configured to retain seed packages. The sensor positioning mechanism may include a moveable track member which translates on a stationary track member, and the sensor device may translate along the moveable track member. A control unit may instruct the sensor positioning mechanism to move with respect to the seed tray assembly to thereby read the machine-readable package identifiers with the sensor device and record the positional layout of the seed packages. One or more cameras may be configured to capture one or more images of the plurality of seed packages retained in the seed tray assembly.

摘要： A cost effective method for reutilizing exiting refinery equipment associated with either a Reformer Unit or Isomerization Unit by converting such units into units and associated processes for hydrodesulfurizing and cracking naphtha feedstocks into light plant gases and chemical feedstocks. These existing Reformer or Isomerization units and processes can be converted into the processes described herein with very little capital expenditures, essentially utilizing almost all of the existing unit equipment, and with little to no major equipment replacements. The processes disclosed herein also effectively reduce the overproduction of naphtha currently experienced in many modern refineries that have resulted from a reduction in overall demand of gasoline products relative to other refinery products.
