The scale and corrosion inhibitions of PASP was evaluated and compared with 2-phosphonobutane-1,2,4-tricar- boxylic acid(PBTCA), 1-hydroxyethylidene-1,1-diphosphonic acid(HEDP) and hydrolyzed polymaleic anhydride(HPMA). The results revealed that the inhibition of the PASP is close to that of PBTCA and HEDP, but much better than that of HPMA.展开更多
