Microwave plasma dissociation of hydrogen sulfide
The Claus technology and its associated tail gas cleanup (SCOT unit) for hydrogen sulfide environmental control recovers the sulfur contained in hydrogen sulfide wastes but loses the hydrogen as water. The alternative treatment process proposed in this paper uses plasma dissociation to recover the hydrogen in addition to the sulfur, thereby saving a significant fraction of the lost energy. The plasma process also appears to be more economical than the Claus/SCOT process. The total capital required for the plasma facility is projected to be $14 million, versus $26 million (including capital cost for the incremental hydrogen generation capacity) for the Calus/SCOT process. Because of energy savings, the annual operating costs for the plasma process are also lower than for the Claus/SCOT process. Assuming a 15% rate of return on capital, the plasma process will produce a net annual profit of $1.8 million relative to the Claus/SCOT. 4 refs., 6 figs., 3 tabs.
