METHOD AND APPARATUS FOR PRODUCING CONSISTENT UREA GREASE Russian patent published in 2012 - IPC C10M177/00 C10M115/08 C10M119/24 C10M169/02 C10M169/06 C07C273/18 B01J14/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing consistent urea grease, which is carried out in an apparatus using an extruder and having several reaction zones mounted in a row and linked by a fluid medium. The apparatus includes: (a) a first feed zone; (b) a second feed zone; (c) a first reaction-mixing zone; and (d) a cooling-mixing zone, wherein said zones lie in the apparatus in the order (a), (b), (c), (d), and the method involves feeding a first starting component into the first feed zone (a); and feeding a second starting component into the second feed zone (b); reaction of the first and second components in the first reaction-mixing zone (c); and cooling and mixing the product of the first reaction-mixing zone in the cooling-mixing zone (d) to obtain consistent urea grease. The invention also relates to apparatus for realising the present method.

EFFECT: invention has such advantages as operational stability, has flexibility, with possibility of applying to many types of consistent urea grease without significant change to the used equipment.
