PROCESS FOR QUICKLY REMOVING HYDROGEN SULFIDE FROM LIQUID SULFIDE AND CATALYTIC SYSTEM USED FOR ITS IMPLEMENTATION

摘要

PROCESS FOR THE RAPID ELIMINATION OF HS PRESENT IN LIQUID SULFUR IN THE SIMPLY DISSOLVED STATE OR IN THE COMBINED STATE OF HYDROGEN POLYSULFIDES. /P P LIQUID SULFUR 9 IS INCORPORATED IN A CATALYTIC SYSTEM 10 CONSISTING OF ONE OR MORE COMPOUNDS OF A BASIC CHARACTER CHOSEN AMONG THE NITROGEN HETEROCYCLIC COMPOUNDS, WHICH ARE SOLUBLE AND STABLE IN LIQUID SULFUR AND HAVE A BOILING POINT HIGHER THAN 200C AT ATMOSPHERIC PRESSURE, AND CONTAINED IN ALL CONDITIONS , FOR EXAMPLE AGITATION 11 AND SPRAYING 12 COMBINED WITH A SCAN OF THE FREE SURFACE 17 OF LIQUID SULFUR BY AN INERATED GAS 7, 8, SUITABLE FOR EVACUATING THE HS FROM THE LIQUID SULFUR CONTAINED IN THE TREATMENT ENCLOSURE 1. P THE CATALYTIC SYSTEM USED ALLOWS FOR SUBSTANTIALLY REDUCING TREATMENT DURATIONS WITHOUT CAUSING COLORING OF TREATED SULFUR OR DEPOSITS.
