Abstract: A process and apparatus for effecting the transportation of sulfur pellets with the recovery of sulfur fines is disclosed. This is accomplished by a combination of steps and apparatus which include pumping water from a water supply into solid sulfur pellets with a jet-venturi/eductor pumping system to produce a sulfur water slurry containing sulfur pellets and sulfur fines, pumping the sulfur water slurry with one or more rotating disk/boundary layer pumps to a series of static screens to remove large lumps and impurities, a sulfur fines slurry, and a washed sulfur pellet slurry, contacting the sulfur pellet slurry with a dewatering disk to remove substantially all the remaining water, transporting the dewatered sulfur pellets to storage, pumping the sulfur fines slurry to a hydrocyclone to separate all the water from the sulfur fines, recycling the recovered water to said water supply following the addition of an alkaline neutralizing agent when needed, and recovering the sulfur fines. The invention substantially reduces air pollution by reducing the amount of sulfur fines released into the air during the unloading of sulfur pellets in bulk. The hydraulic transportation feature of this invention eliminates the use of mechanical loaders, cranes, open air hoppers, and open air transfer points that normally create and disperse sulfur fines into the atmosphere during their use in the movement of solid sulfur. It enables sulfur pellet transfer operations to take place in most weather conditions, rather than requiring interruption when wind speed and time exceed regulatory guidelines. The State of Florida requires operators to cease the unloading of sulfur pellets from a marine vessel whenever wind speed exceeds 18 miles per hour for a 5-minute time span.

Abstract: an improved process for the granulation or coating of hygroscopic or nonhygroscopic materials where melt is sprayed onto cascading granules of common or uncommon substrate in an enclosed vessel such as a rotary drum preferably with lifting flights which provide maximum mixing of the granules and the atmosphere enclosed in the unit and where heat given off by solidification of the melt is absorbed by evaporation of water which is atomized as an extremely fine mist into areas of the vessel which are not subtended by falling granules. Evaporation is effected without impingement of the mist on the granules or vessel internals. Air for evaporation is pulled through the vessel concurrent with the flow of granules and its moisture content is regulated below the critical humidity of the granules throughout the vessel. Some recycle of undersize granules discharged from the vessel is maintained for size control; however, examples show the recycle rate decreased by 87 percent over recycle cooled processes as 73 percent of the heat evolved is removed by evaporation of water mist. An equation is developed which mathematically represents the thermodynamics of the process and specific values are presented for variables when granulating sulfur or urea.

Abstract: A composition containing nano-sulfur and an application thereof, the composition containing nano-sulfur contains nano-sulfur and further contains an anti-agglomeration agent used for preventing or delaying the agglomeration of the nano-sulfur, is provided. The composition containing nano-sulfur may be widely used for preparing toiletries for use on the surface of the skin on humans or animals, pharmaceutical compositions treating skin disorders, pesticides, preservatives for vegetables and fruits, additives for animal feed, additives for mold prevention in paint, mold prevention agents for textiles or (textile) mite-killing agents. The composition containing nano-sulfur is easy to prepare, and the nano-sulfur may remain in the nano state for a long time, reducing or even eliminating the occurrence of the agglomeration of the nano-sulfur, while achieving the goals of being applied in various products and preventing fungus by simply adding a very small amount.
