Sulfur pumping

Molten sulfur has a viscosity (-0.01 kg m 1 s 1, 400-420 K, Fig. 3.2) about ten times that of water (-0.001 kg m 1 s 1, 293 K). Its density is 1.8 kg/m3. It is easily moved in steam jacketed steel pipes (Jondle and Hombaker, 2004). Steam heated pumps much like that in Fig. 9.2 are used. Molten sulfur is an excellent lubricant at 410 K. Sulfur pump impellers need no additional lubrication. [Pg.21]

Solid sulfur is dumped on the grids of the melter and is melted by means of the heat provided through steam coils in the melter. An agitator installed in the melter helps to melt the sulfur at a faster rate. Liquified sulfur is pumped to the pressure leaf filter and the purified sulfur stored in a separate compartment equipped with steam coils. Sulfur pumps are used to feed the liquid sulfur to the sulfur burner at a... [Pg.9]

Steam is also consumed in the plant for keeping the sulfur in the settling and pumping sections in a molten state, for heating the sulfur filter jacket, and for keeping the sulfur pumps and feed lines hot. [Pg.90]

Cost of filtration it is found more advantageous to filter the sulfur rather than filter the hot gases since this reduces wear and tear on the sulfur pumps, spray gun, etc. [Pg.93]

The typical duty specification required for this service is of high deUvery head and very low flow capacities. Sulfur has a melting point of 119 °C and a peculiar characteristic of a sharp rise in viscosity at a temperature above 150 C. It becomes extremely difficult to pump liquid sulfur above this temperature. The practical range for operating a sulfur pump is 125-135 °C. [Pg.133]
