Processes for reducing the level of impurities in alumina trihydrate produced in the Bayer process are disclosed, wherein alumina trihydrate-containing process streams are flocculated with hydroxamated polymers and centrifuged.
摘要:
A burner apparatus and method for reducing nitrogen oxides that are formed during combustion of gaseous fuel. Primary gaseous fuel and excess oxidant are premixed to form a fuel/oxidant mixture which is introduced into and combusted within a primary combustion zone. Primary combustion products are introduced into a secondary combustion zone. Secondary gaseous fuel is also introduced into the secondary combustion zone and is preferably mixed with the primary combustion products. The mixture of secondary gaseous fuel and primary combustion products is combusted in a secondary combustion zone. A portion of the secondary combustion products are internally recirculated into the secondary combustion zone. The overall combustion products can be externally recirculated and introduced into the primary combustion zone. A portion of the fuel/oxidant mixture, with or without the recirculated overall combustion products, can be bypassed around the primary combustion zone and introduced into the secondary combustion zone.
摘要:
Disclosed is a dust suppression suspension and method of suppressing dust evolution from a dust generating material by contacting the material with the suspension. The suspension includes sugar polymer particles suspended in an oil base, and further includes a thickener, a surfactant and an emulsifier. The suspension may be applied directly to the dust generating material followed by water addition, or may be emulsified in water and then applied to the material.
摘要:
A process for flameproofing cellulosic fabrics which comprises impregnating the fabric with an aqueous solution of a THP salt with or without condensation with a nitrogen-containing compound, and treating the impregnated fabric with ammonia to produce a cured resin, wherein the treatment with ammonia is carried out by passing the impregnated fabric through seals into and out of a closed chamber and in contact with at least one duct located in the chamber and having one or more orifices through which gaseous ammonia is caused to issue and pass through the fabric over its width, the chamber being provided with means to prevent condensed water formed by evaporation and/or chemical action from dripping on to the fabric.

Methods, systems, and computer-readable media provide for generating a report indicating job availability. According to embodiments, a method for generating a report indicating job availability is provided. According to the method, a selected assignment group is displayed. A number of status messages received by a technician in the selected assignment group is displayed. The status messages indicate that no jobs are available for the technician. An amount of lost time associated with the technician in the selected assignment group is determined. The lost time includes a difference between a time at which the technician received one of the status messages and a time at which the technician is dispatched to a next job. The amount of lost time associated with the technician in the selected assignment group is displayed.
