Question:

2-Mercaptoethanol (C2H6OS) is produced by reacting ethylene oxide (C2H4O) with hydrogen sulfide (H2S) as per the following reaction equation.

image text in transcribed

The reaction takes place in the presence of Thiodiglycol and Zeolites as catalysts. The molecular weights (lbm/lbmol) are, ethylene oxide = 44, hydrogen sulfide = 34, 2-mercaptoethanol = 78. To produce 1000 lbm/hr of 2-mercaptoethanol, determine the amounts (lbm) of reactants required if 25% excess hydrogen sulfide needs to be used.
