System for purification of acrylamido tertiary butyl sulfonic acid and process thereof

Abstract

A system (100) for purification of acrylamido tertiary butyl sulfonic acid monomer (ATBS) and process (400) thereof are disclosed herein. The said system (100) may comprise a continuous rotary pressure filter (102), a continuous dryer (103), a product cooler (104), a granulation unit (105) comprising a roller compactor (106), a granulator (107), a sifter (108) and a powder transfer system (PTS) (109). The said continuous rotary pressure filter (102) comprises a scrapper (203) and a rotating filter drum (204). The said rotating filter drum (204) further comprises plurality of filter cells (205). The pressure applied in the continuous rotating pressure filter (102) enables maximum filtration of filtrate from wet cake of ATBS monomer and thereby producing the ATBS product with reduced yellowness. The powder transfer system (PTS) (109) comprises at least four valves controlled to enable the production of high yield of ATBS with uniform particle size and shape.
