Abstract

método e sistema para controlar uma unidade de leito adsorvente a presente invenção fornece um método e um sistema de controle para controlar uma unidade de leito adsorvente em que uma concentração de leito adsorvente de uma impureza dentro de um leito adsorvente da unidade de leito adsorvente é medida. a concentração de leito adsorvente é controlada manipulando-se o tempo de ciclo de alimentação durante o qual um leito adsorvente que está adsorvendo as . impurezas para manter a concentração de leito adsorvente em uma concentração de leito de adsorção alvo. a concentração de leito de adsorção alvo é determinada de modo que a concentração de impureza do produto seja mantida em concentrações de impureza do produto alvo. o método e sistema de controle podem incorporar um nível de supervisão de controle reativo a níveis de concentração de impureza do produto e alvos relacionados para determinar a concentração de leito de adsorção alvo e um nível primário de controle que calcula o tempo de ciclo de alimentação com base em um erro entre as concentrações de leito de adsorção medidas e alvo. controle proporcional e integral pode ser usado para tais propósitos.
