Abstract: THE PRESENT INVENTION RELATES TO AN IMPROVED METHOD OF PRILLING SULFUR FOR TRANSPORTING IN A PIPELINE WITH A MINIMUM OF SULFUR PRECIPITATION AND ADHERENCE TO THE INTERNAL PARTS OF THE PIPELINE SYSTEM. THE IMPROVEMENT COMPRISES THE PRILLING OF SULFUR INTO A POLYHYDROXY COMPOUND OR AQUEOUS MIXTURES THEREOF TO FORM A PROTECTIVE COATING ON THE SURFACES THEREOF TO INHIBIT THE DEGRADATION CAUSED BY THE PHYSICAL TREATMENT GIVEN SAME BY THE MOVEMENT THROUGH THE PIPELINE AS WELL AS THE CHEMICAL ATTACK BY THE CARRIER FLUID.

Abstract: 1. A METHOD FOR REMOVING SULFUR OXIDES FROM GASEOUS STREAMS COMPRISING: CONTACTING SAID GASEOUS STREAMS WITH A MOLTEN MIXTURE HAVING A PH FROM ABOUT 7.0 TO ABOUT 10.0 AND CONTAINING FROM ABOUT 10 TO ABOUT 99 WEIGHT PERCENT METAL ALKANOATE, WHEREIN SAID METAL IS SELECTED FROM THE GROUP CONSISTING OF SODIUM, POTASSIUM, LITHIUM AND MAGNESIUM, AND WHEREIN THE ALKYL MOIETY OF SAID ALKANOATE CONTAINS FROM 1 TO ABOUT 4 CARBON ATOMS; AND FROM ABOUT 1 TO ABOUT 90 WEIGHT PERCENT OF AN ALKALINE MATERIAL SELECTED FROM THE GROUP CONSISTING OF METAL HYDROXIDES, METAL CARBONATES, METAL BICARBONATED AND COMBINATIONS THEREOF WHEREIN SAID METAL IS SELECTED FROM THE GROUP CONSISTING OF SODIUM, POTASSIUM, LITHIUM AND MAGNESIUM THEREBY SELECTIVELY ABSORBING SULFUR OXIDES AND RECOVERING A GASEOUS STREAM HAVING A REDUCED SULFUR OXIIDE CONTENT.
