PROCESS FOR PREVENTING THE PRECIPITATION OF ELEMENTARY SULFUR IN RISER PIPES OF PROBES FOR NATURAL GAS

摘要

The present invention provides a process for preventing the precipitation of elementary sulfur in the riser pipes of probes for natural gas, and a solvent for sulfur which solvent is particularly suitable for this process. For the dissolution of the precipitating elementary sulfur an ester of an optionally mono- or poly-unsaturated fatty acid and/or the reaction product of H2S with an ester of a mono- or poly-unsaturated fatty acid, optionally in solution, is used, the solvent for sulfur being liquid under the conditions in the mining probe being sparingly soluble in the gas, and being added to the gas stream at a suitable place.
