    Abstract: The invention relates to the use of at least one compound of formula (1): R-Sn-R′  (1) wherein R and R′ are each a hydrocarbon radical containing between 1 and 12 carbon atoms and n is a whole number between 1 and 8, for maintaining the viscosity of liquid sulfur at a value lower than 60,000 mPa·s, preferably lower than 30,000 mPa·s, especially preferably lower than 10,000 mPa·s. The invention also relates to a method for preparing low-viscosity liquid sulfur and to liquid sulfur compositions comprising at least one compound of formula (1).

    Abstract: Elemental sulfur is combined with either liquid anhydrous ammonia, liquid sulfur dioxide, or both to form a solution or slurry which is transportable through pipelines or other transport vessels without a risk of clogging due to the environmental temperature drops that these vessels typically encounter. This unusual behavior and the advantages it offers arise from the discovery of unexpected solubility vs. temperature relationships of elemental sulfur in each of these two carriers. Among the advantages are significant improvements in the economics of many industrial chemical processes that involve the presence of sulfur either in elemental or chemically combined form, including natural gas or tar sands production and processing, hydrogen sulfide abatement, hydrogen production without carbon dioxide emissions, and sulfur extraction from ores, subterranean deposits, depositories, or fouled impaired industrial facilities. Large-scale ramifications for energy and fertilizer mineral resource utilization, greenhouse gas abatement, hydrogen economy, and nitrogen fertilizer production are taught.

    Abstract: An improved method of transporting sulfur-liquid hydrocarbon slurries through pipelines without causing sulfur agglomeration, sticking, deposition or plugging of the pipelines. The invention relates to an improved and novel process of preventing sulfur agglomeration, sticking, deposition and plugging of pipelines transporting sulfur in the form of a sulfur-liquid hydrocarbon slurry.
