More Information
Summary:An apparatus and method for purifying a Bayer process stream includes a filtration stage including at least one filter configured to filter particulate matter from at least one ionic liquid stream from an extraction stage, a stripping stage, and a regeneration stage. Filtering particulate matter from at least one of the ionic liquid streams reduces the amount of circulating particulate matter and reduces the likelihood of fouling formation. 一种用于净化拜耳工艺流的设备和方法，包括过滤级，该过滤级包括至少一个过滤器，该过滤器被配置成从来自提取级、剥离级和再生级的至少一种离子液体流中过滤颗粒物质。从至少一种该离子液体流中过滤颗粒物质减少了循环的颗粒物质的量并降低了积垢形成的可能性。
