REMOVAL OF RESIDUAL SULFUR COMPOUNDS FROM A CAUSTIC STREAM |
摘要 |
<p>A process for the removal of residual sulfur compounds from a liquid caustic stream is disclosed. One embodiment of my invention adsorbs disulfides from a caustic stream using an activated carbon adsorbent while another combines both oxidation and adsorption in single step to remove residual sulfur compounds from a rich caustic stream using metal phthalocyanine supported on a solid adsorbent. This process is especially useful as a polishing step in a caustic regeneration process flow scheme.</p> |
