Title
(EN) PRESSURE CONTROLLER
(FR) CONTRÔLEUR DE PRESSION
Abstract
(EN)
The invention pertains to a pressure controller for use in operating parallel reactors. The pressure controller comprises a reference pressure controller, that is adapted to control a reference pressure in a control chamber. The reference pressure controller comprises: a first restrictor channel, a second restrictor channel, a fluid passage, which fluid passage extends between the outlet of the first restrictor channel and the inlet of the second restrictor channel, a pressure control fluid source being adapted to provide a flow of pressure control fluid, having an entrance pressure at the inlet of the first restrictor channel and an exit pressure at the outlet of the second restrictor channel, said flow of pressure control fluid experiencing a first pressure drop Δρ1 over the first restrictor channel and a second pressure drop Δρ2 over the second restrictor channel, a connector connecting the fluid passage to the control chamber, the pressure control fluid at the connector having an intermediate pressure, said intermediate pressure being determined by the ratio between the first pressure drop Δρ1 and the second pressure drop Δ⩽ρ2, - a controllable thermal device, adapted to heat and/or cool the first restrictor channel and/or the second restrictor channel, therewith influencing the ratio between the first pressure drop Δρ1 and the second pressure drop Δρ2.

L'invention concerne un contrôleur de pression destiné à être utilisé pour l'exploitation de réacteurs parallèles. Le contrôleur de pression comprend un contrôleur de pression de référence, qui est adapté pour commander une pression de référence dans une chambre de commande. Le contrôleur de pression de référence comprend : un premier canal limiteur, un second canal limiteur, un passage de fluide, lequel passage de fluide s'étend entre la sortie du premier canal limiteur et l'entrée du second canal limiteur, une source de fluide de commande de pression qui est adaptée pour produire un écoulement de fluide de commande de pression, ayant une pression d'entrée à l'entrée du premier canal limiteur et une pression de sortie à la sortie du second canal limiteur, ledit écoulement de fluide de commande de pression subissant une première chute de pression Δρ1 sur le premier canal limiteur et une seconde chute de pression Δρ2 sur le second canal limiteur, un connecteur reliant le passage de fluide à la chambre de commande, le fluide de commande de pression au connecteur ayant une pression intermédiaire, ladite pression intermédiaire étant déterminée par le rapport entre la première chute de pression Δρ1 et la seconde chute de pression Δ⩽ρ2, — un dispositif thermique contrôlable, adapté pour chauffer et/ou refroidir le premier canal limiteur et/ou le second canal limiteur, influençant avec ceux-ci le rapport entre la première chute de pression Δρ1 et la seconde chute de pression Δρ2.
