Cooling water systems are the most common method for re-jection of waste heat in chemical processes. Conventional re-circulating cool-ing have a network coolers parallel configuration, de-manding both large cooling circulation and towers. Althoughreuse reduces amount that is necessary sys-tem and, hence, increases tower performance capacity, it maysignificantly increase pressure drop due to series-parallel arrangements.This paper develops methodology calculation basedon Graph Theory. From adjacency matrix cooler network, uses thetopological sorting critical path algorithms order evaluate pres-sure with arrangements. Applyingthis reuse, possibleto analyse impact increased when compared
