Abstract
The invention provides a method for purifying MTO quench water and scrubbing water via mini-hydrocyclone separation, comprising: removing the entrapped catalyst particles from the MTO quench water via mini-hydrocyclone separation; cooling the quench water purified by mini-hydrocyclone separation so as to effect the recycling of water; removing the entrapped catalyst particles from the MTO quench water to be stripped via mini-hydrocyclone separation, so as to reduce the deposition of the catalyst particles within the stripping tower; removing the entrapped catalyst particles from the MTO scrubbing water via mini-hydrocyclone separation; and cooling the scrubbing water purified via mini-hydrocyclone separation so as to effect the recycling of water. The invention also provides an apparatus for purifying MTO quench water and scrubbing water via mini-hydrocyclone separation.
