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 At 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.
