Abstract
Un proceso para producir un polímero en un reactor de bucle continuo para suspensiones, que comprende alimentar un catalizador, un monomero, y opcionalmente por lo menos uno de los siguientes: un comonomero, un co-catalizador, un diluyente, un modificador de los polímeros, o mezclas de los mismos, en el reactor; donde el catalizador es introducido en el reactor desde multiples entradas para el catalizador; y recuperar el polímero del reactor. Un proceso para producir un polímero en un reactor de bucle continuo para suspensiones, que comprende: hacer reaccionar un monomero en un diluyente hidrocarburo de manera de formar una suspension de polimerizacion de solidos poliméricos en un medio líquido; descargar una porcion de la suspension de polimerizacion como efluente de suspension que comprende una suspension de solidos poliméricos descargados en un medio líquido a través de por lo menos dos conductos de descarga; combinar el efluente de por lo menos dos de los conductos de descarga; someter a evaporacion instantánea (flashing) el efluente combinado en un primer tanque de flash, de manera de formar un primer vapor de flash y una primera suspension de flash; y condensar por lo menos una porcion del primer vapor de flash, sin compresion. Un reactor de bucle para suspensiones, que comprende: multiples entradas para el catalizador; por lo menos una entrada de alimentacion; por lo menos un conducto de descarga; y por lo menos un circulador en el reactor; estando las entradas para el catalizador situadas dentro del 45% de los puntos de simetría del reactor de bucle.A process for producing a polymer in a continuous loop reactor for suspensions, which comprises feeding a catalyst, a monomer, and optionally at least one of the following: a comonomer, a co-catalyst, a diluent, a polymer modifier , or mixtures thereof, in the reactor; where the catalyst is introduced into the reactor from multiple inlets for the catalyst; and recover the polymer from the reactor. A process for producing a polymer in a continuous loop reactor for suspensions, comprising: reacting a monomer in a hydrocarbon diluent so as to form a polymerization suspension of polymer solids in a liquid medium; discharge a portion of the polymerization suspension as a suspension effluent comprising a suspension of polymer solids discharged into a liquid medium through at least two discharge ducts; combine the effluent from at least two of the discharge ducts; subject to flash evaporation the combined effluent in a first flash tank, so as to form a first flash vapor and a first flash suspension; and condense at least a portion of the first flash steam, without compression. A loop reactor for suspensions, comprising: multiple entries for the catalyst; at least one feed inlet; at least one discharge duct; and at least one circulator in the reactor; the entries for the catalyst being within 45% of the symmetry points of the loop reactor.
