Abstract 1. A PROCESS FOR REDUCING THE HYDROGEN SULFIDE CONTENT OF A COKE OVEN GAS EVOLVED DURING THE COKING OF COAL IN A COKE OVEN COMPRISING, PASSING A COKE OVEN GAS EVOLVED DURING THE COKING OF COAL IN A COKE OVEN THROUGH A LIQUID WASHING MEDIUM IN A FIRST STATE AND REMOVING A SUBSTANTIAL PORTION OF THE HYDROGEN SULFIDE FROM THE GAS, SUBJECTING THE LIQUID WASHING MEDIUM CONTAINING THE HYDROGEN SULFUDE TO AN OXIDIZING MEDIUM TO OXIDIZE A SUBSTANTIAL PORTON OF THE HYDROGEN SULFIDE IN THE LIQUID WASHING MEDIUM T ELEMENTAL SULFUR, SEPARATING THE ELEMENTAL SULFUR FROM THE LIQUID WASHING MEDIUM, RECYCLING A MAJOR PORTION OF THE LIQUID WASHING MEDIUM AFTER SEPARATING THE ELEMENTAL SULFUR THEREFROM TP SAID FIRST STAGE TO REMOVE HYDROGEN SULFUDE FROM THE COKE OVEN GAS EVOLVED DURING THE COKING OF COAL IN A COKE OVEN, SEPARATING A MINOR PORTION OF THE LIQUID WASHING MEDIUM AND SUBJECTING SAID SEPARATED MINOR PORTION TO AN ELEVATED TEMPERATURE TO VOLATILIZE CARTAIN VOLATILE COMPOUNDS, INTRODUCING SAID VOLATILE COMPOUNDS INTO A STREAM OF COKE OVEN GAS EVOLVED DURING THE COKING OF COAL IN A COKE OVEN PRIOR TO PASSING THE COKE OVEN GAS THROUGH A LIQUID WASHING MEDIUM IN SAID FIRST STAGE, AND MIXING THE RESIDUE OF SAID MINOR PORTION OF LIQUID WASHING MEDIUM WITH COAL TO BE COKED IN A COKE OVEN.
