| titleOfInvention | Sulfur removal process from an acrylate stream |
| abstract | Broadly, the present invention is directed to a process for the removal of sulfur from an acrylate stream. In particular, disclosed is a process for the recovery and reuse of an acid catalyst employed primarily in the reaction to form acrylic esters. Reaction end components which include the acid catalyst employed in the reaction process, are directed to an extractor for contact with water. Upon contact with water, a phase separation occurs between the acid catalyst/water mixture and other organic matter. The organic matter is sent forward for product purification while the acid/water mixture is recycled to the reaction process. The present invention employs the use of an extractor to aid in the separation of the acid catalyst from the reaction by-products. This removal of acid results in fewer organic sulfur components to be emitted from the reaction process and hence is a more environmentally friendly process. |
