Systems and methods for hydrocarbon recovery

A method has been invented for recovering hydrocarbons from an earth formation containing hydrocarbons, the method including injecting a recovery injectant into the earth formation at a plurality of injection points spaced apart by about 14 to about 208 feet, and producing hydrocarbons from the formation with at least one producer well. In one aspect the method includes injecting steam into an earth formation which contains oil bearing diatomite at a plurality of injection points spaced apart by about 14 to about 208 feet, and producing hydrocarbons from the formation with a one or more producer wells extending into the oil bearing diatomite formation, with a plurality of producer wells spaced apart by a distance ranging between about 14 to about 149 feet, injecting steam into the oil bearing diatomite at an injection rate of between about 10 to about 149 barrels of steam per day per hundred feet thickness of diatomite, and injecting the steam at a pressure between about 10 p.s.i. to about 260 p.s.i. The present invention also discloses a method for treating a hydrocarbon-bearing diatomite formation including applying an artificial overburden over at least a portion of the formation and applying a variable well spacing as needed. A field on an earth formation has been invented for recovering hydrocarbons, the earth formation having an earth surface above it, the field including a plurality of injector well and a plurality of producing wells, the field including at least one injector well per acre of earth surface above the earth formation and at least one producing well per acre. Certain parts of the wells may be in below-grade chambers.

Novel method for processing calx sodica sintered alumina by dry method

The invention discloses a processing method for sintering alumina by a novel dry soap lime, which comprises the following steps: (1) raw materials, i.e., broken bauxite, limestone, sodium carbonate and coal are sent to a ball mill to be milled until the oversize product of 100<#> is not lager than 5 percent, and raw meal is made into raw meal balls of 30-50mm; (2) clinker sintering: the raw meal of the step (1) is calcined in a vertical kiln at the temperature of 1150-1250 DEG C to prepare the clinker; (3) clinker leaching: the clinker is leached by the lotion of Bayer process, and then the solution is sent to a desilication groove; (4) decomposition: the desiliconized solution is combined with a Bayer solution, and then the mixture is put into a leaf filter and enters a decomposer to be decomposed by adding seed crystal; and (5) roasting: aluminum hydroxide is roasted into alumina at 950-1200 DEG C. The processing method has the beneficial effect that the water content of the raw meal is reduced to 10-15 percent, thus greatly reducing the specific heat consumption in the sintering process by little change and acquiring higher economic benefits.

Method of making a double-walled flexible tubing product with helical support bead and heating conductor

A flexible double-walled plastic tubing product includes a helically wound support bead between inner and outer walls, and an helically wrapped electrical resistance heating conductor is disposed adjacent to the inner wall in good heat transfer relation to fluid flow within the tubing product. Fluid flow within the tubing product is insulated against heat loss to ambient by the helical support bead and a trapped "dead-air" space between the walls of the tubing product. Apparatus and method for making the tubing product are disclosed.

The invention discloses an efficient energy saving electro heating multipurpose cooker utilizing a new method of accurate temperature controlling and healthy cooking. The technical scheme of the invention is as follows: the outside surface of the cooker body is provided with an ambient temperature sensor; the base of the cooker is provided with an inner pot temperature sensor; the cooker body, thecooker cover and the cooker base are all set to be closed efficient heat insulation interlayers; the closed heat insulation interlayer on the cooker base is arranged between the casing of the cookerbase and the electro heating device; a hallow cavity is arranged between the casing of the cooker base and the closed heat insulation interlayer; and the purposes of energy saving, discharge reducingand healthy cooking can be realized by setting standard control values such as ambient temperature or temperature drop, cooking/steaming temperature and time and the like by an automatic control device and by comparing the ambient real-time temperature or temperature drop with the inner pot real-time temperature to control the power on and power off of the electro heating device. The efficient energy saving electro heating multipurpose cooker can be used for cooking rice, cooking congee, cooking soups and steaming food; compared with various electro rice/congee/soup cooker in the prior art, the invention can save electricity by 30%-50% and can be widely used in families, dining halls and catering enterprises in cities and towns.

Soil pasteurizing apparatus and method using exhaust gas

In agriculture, one of the most important issues is the extent to which the yield of high quality crops can be increased while saving labor and reducing costs. However, there are many problems in that so-called injuries of crops due to continuous cropping and other causes seriously reduce productivity. The present invention provides an apparatus and a method that can pasteurize soil using gases emitted from the engine of a tractor, while at the same time, carbon dioxide, sulfur oxides, and other acidic fumes in exhaust gas are fixed as calcium salts with slaked lime that has been applied in advance on the soil to be pasteurized, and these gaseous components can, as much as possible, be prevented from escaping into the atmosphere.

Compact fuel cell package

ActiveUS20060134470A1Decrease heat lossIncrease thermal efficiencyReactant parameters controlFuel cells groupingElectric energyUnit volume
The invention relates to a compact and portable fuel cell package. The package includes a fuel cell that generates electrical energy. Some packages also include a fuel processor that produces hydrogen from a fuel source. Fuel cell packages described herein provide power densities (power per unit volume or mass) at levels not yet seen. One package employs an interconnect disposed at least partially between a fuel cell and a fuel processor. The interconnect forms a structural and plumbing intermediary between the two. Given the portable size of fuel cell packages described herein, the invention is well suited to power portable electronics devices. One portable fuel cell package includes a tether, which allows electrical and detachable coupling to an electronics device.
