Bench-scale testing and evaluation of the Direct Sulfur Recovery Process

PDF Version Also Available for Download.

Description

The present work seeks to (1) demonstrate the DSRP in an integrated two-stage bench-scale unit scaled up by a factor of up to 40, for up to 99 percent or higher recovery of sulfur, (2) explain the high sulfur yield and mechanism of DSRP reactions by conducting kinetic experiments and advanced thermodynamic calculations, and (3) continue technology transfer to the point where industry is willing to support further DSRP development. The DSRP Bench-Scale Unit hardware has been described in detail previously (Gangwal and McMichael, 1990; Gangwal and McMichael, 1991). The unit consists of a simulated off-gas and coal-gas delivery system ... continued below

Description

The present work seeks to (1) demonstrate the DSRP in an integrated two-stage bench-scale unit scaled up by a factor of up to 40, for up to 99 percent or higher recovery of sulfur, (2) explain the high sulfur yield and mechanism of DSRP reactions by conducting kinetic experiments and advanced thermodynamic calculations, and (3) continue technology transfer to the point where industry is willing to support further DSRP development. The DSRP Bench-Scale Unit hardware has been described in detail previously (Gangwal and McMichael, 1990; Gangwal and McMichael, 1991). The unit consists of a simulated off-gas and coal-gas delivery system connected to two high-pressure reactors and condensers in the configuration shown conceptually in Figure 1. The system is rated to 400 psig and the reactors, capable of operation at up to 400 psig at 750{degree}C, hold up to 1 L of catalyst each. The inlet and outlet gases are analyzed using two gas chromatographs (GCs) and a continuous SO{sub 2} analyzer. One major change recently made to the unit consists of installing advanced condensers suggested by experts in the field to facilitate more efficient separation of the sulfur after each reactor. A schematic diagram of the advanced condenser is shown in Figure 2. The sulfur-laden gas is cooled by surrounding steam at 250{degree}F in a coil and then flashed into the sulfur collection pot for separation of gas and sulfur. A sulfur drain is included so that it is not necessary to dismantle the condenser after every run. The ability to drain the sulfur during a run allows extended runs to be carried out. Also fittings are provided in strategic locations to allow dismantling when cleanup becomes necessary.
