Abstract: Systems and methods for producing ammonia. The system can include a first ammonia converter, a second ammonia converter, a product separator, and an ammonia recovery unit. The first ammonia converter can be adapted to react a syngas to produce a first ammonia product and a first purge gas. The second ammonia converter can be in fluid communication with the first ammonia converter and can be adapted to react the first purge gas to produce an effluent. The product separator can be in fluid communication with the second ammonia converter and can be adapted to separate the effluent to produce a second ammonia product and a second purge gas. The ammonia recovery unit can be in fluid communication with the product separator and can be adapted to separate at least a portion of the second purge gas to produce a third ammonia product and a third purge gas.

Abstract: A mill, particularly a mill for extracting juice from cane sugar, has a fixed top roller (24), and feed discharge rollers (25) and (26) which are independently pivotable by respective power operated means (47, 51) to vary the feed opening between the feed roller and top roller and the discharge opening between discharge roller and top roller. A trash plate (55) for transferring material between the feed opening and the discharge opening is connected to the feed roller for pivotable movement therewith.
