The Claus process is the most significant gas desulfurizing process that recovers elemental sulfur from gaseous hydrogen sulfide found in raw natural gas and from the by-product gases containing hydrogen sulfide derived from refining crude oil, gasification, and other industrial processes. Fluor's proprietary Claus process can accommodate a ...

uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.

This technology produces no waste water and the CO2 emissions are 40% lower than the standard process without iron oxidation energy use. For this reason, BUS Zinkrecycling Freiberg won the 1999 Environment Award for the energetic optimisation of a rotary kiln system, and in 2000 the Innovation Award for the SDHL process for the

Potential emission sources in gypsum processing plants are shown in Figure 11.16-1. While particulate matter (PM) is the dominant pollutant in gypsum processing plants, several sources may emit gaseous pollutants also. The major sources of PM emissions include rotary ore dryers, grinding mills, calciners, and board end sawing operations.

Gypsum processing equipment differs significantly in scale and level of technology. some plants produce one or two tonnes per day using low-cost manual technologies, some other plants of a thousand tonnes per day that are highly mechanized and capable of producing different types and grades of gypsum plaster or plaster boards.
