A method and system for collecting gaseous nitrogen compounds into an aqueous solution are provided. The method enables the combination of gaseous sulfur and nitrogen compounds in the aqueous solution to generate ammonium compound components, to include ammonium sulfate. Sulfur may be pressure injected into the solution as gaseous sulfur dioxide. Optionally, carbon may be introduced into the solution as gaseous carbon dioxide. The sulfur may be earlier sourced by a burning of a sulfurous solid. The pH of the solution may be monitored and the introduction of ammonia, carbon and/or sulfur may be halted or constrained while the pH of the solution is measured outside of specified range. The solution may be allowed to age to permit a mix of compounds of ammonium carbonate, ammonium bicarbonate and ammonium carbomate to restabilize and thereby encourage a renewed surge of ammonium sulfate generation.

Process and apparatus for capturing gaseous ammonia

An apparatus and a method for sorting scrap metal containing at least two categories of metals are provided. An x-ray beam is directed towards at least a portion of a particle of scrap metal. Backscattered x-rays, forward scattered x-rays, and transmitted x-rays from the particle are measured and input into a classifier, such as a database with a cutoff plane. The scrap metal is sorted into a first category and a second category on the scrap metal by a controller. An x-ray source for a scanning system is provided with an electron beam generator, an electromagnetic beam focusing coil, a pair of saddle shaped beam steering coils, and a target foil to create a scanning x-ray beam along a plane.

Scrap metal sorting system

A linear source of x-rays is disclosed wherein an elongated filament, mounted within a cylindrically formed anode, provides electrons around the filament, and along the length of said filament. The anode that comprises a high Z material such as gold, receives the electrons and emits X-rays in a 360 degree arc and along a substantial length of the anode. In one embodiment the tube is used for irradiation purposes.
