| 摘 要： | 选用焦化粗柴油为萃取剂，在转盘萃取搭连续试验装置中，对催化裂化含酚废水进行脱酚预处理。结果表明，用焦化粗柴油做萃取剂，进水ｐＨ值为８０～９０不加调节；油水比（体积比）１７∶１～２１∶１；转盘转数１１００ｒ／ｍｉｎ，酚萃取脱除率达到８５％以上。萃取后的粗柴油依据现有工艺而进行加氢精制，不需进行再生等后处理。整个萃取工艺简单易行，能满足预处理的要求

| Abstract: | A dephenolization is carried
out on the phenol\|bearing wastewater of the fluid catalytic cracking(FCC)using the coking raw
diesel oil as an extraction agent and taking a rotary table tower as a continuous testing
device.It is indicated by the results that the dephenolization rate by extraction can be up to over
85% when the influent having pH value of 8090 without any adjustment,oil/water ratio (by
volume)being 1.712.11 and the revolutions of the rotary table being 1100r/min.The extracted
diesel oil is hydrofined and needs no regeneration.The whole extraction process is simple in
operation and can meet the needs of the pretreatment. |
