Abstract

Un método y aparato para mitigar la formacion de slug en una corriente de fluido multifásica que fluye a través de un conducto donde el conducto comprende una primera porcion y una segunda porcion inclinada hacia arriba respecto de la primera porcion y donde la corriente de fluido multifásica comprende una fase gaseosa y una fase líquida, donde el método comprende los pasos de: (a) determinar la presion en el conducto corriente arriba de una zona de formacion de slug; (b) determinar la presion en el conducto corriente abajo de la zona de formacion de slug; (c) determinar la diferencia de presion real a través de la zona de formacion de slug restando la presion corriente abajo que se obtuvo en el paso (b) de la presion corriente arriba que se obtuvo en el paso (a); (d) determinar el error entre la diferencia de presion objetivo y la diferencia de presion real; (e) producir una senal que comprende un primer componente que es proporcional al error y un segundo componente que es proporcional a la tasa de cambio del error durante el transcurso del tiempo; y (f) usar la senal que se produjo en el paso (e) para controlar la posicion de una válvula estranguladora ajustable situada corriente abajo de la zona de formacion de slug de tal manera de estabilizar las variaciones que surgen de la diferencia de presion real durante el transcurso del tiempo.
