PRODUCTION OF LIQUID SULFUR TRIOXIDE |
摘要 |
<p>PRODUCTION OF LIQUID SULFUR TRIOXIDE A process for production of liquid sulfur trioxide in which sulfur is combusted with oxygen in one stage at a furnace outlet temperature of between about 1000.degree.F and about 2700.degree.F, and the resulting sulfur dioxide-containing gas is subjected to multistage catalytic conversion to sulfur trioxide, the sulfur trioxide being recovered by conventional condensation techniques. Substantially all the uncondensed gases from the sulfur trioxide condensation step are recycled to the combustion step.</p> |
