Apparatus and method for distributing fluids in industrial facilities

Abstract

The invention relates to a device (100) for distributing a fluid (110) in an industrial installation, the device comprising: at least a fluid distribution conduit (1); a discharge conduit (2) originating from the distribution conduit (1 ); distribution valve (3), which is positioned on the distribution pipe (1) and controls the distribution of fluid (110) between the upstream area (200) and the downstream customer (300); discharge valve (4), the A discharge valve is positioned on the discharge pipe (2); and a measuring device (5) for measuring in real time a characteristic parameter (P ). The distributing device (100) comprises a module (6) for calculating a sliding threshold (St) of the characteristic parameter (P), and a control device (7), which is configured to be based on said sliding threshold (St) and determined by The result of the comparison between the instantaneous values ​​(Vt) of the characteristic parameter (P) measured by the measuring device (5) controls the gradual partial opening or closing of the discharge valve (4) in order to prevent undesired opening of the discharge valve , and thus prevents the risk of fluid loss and potential additional costs of the method implemented by industrial facilities. The invention also extends to a method for controlling the dispensing of a fluid (110) implemented by a dispensing device (100) according to the invention.

Description

Technical field [0001] The present invention relates to the fields of industrial facilities using one or more fluids, and more particularly to allocation of these fluids within these facilities. [0002] In a known manner, this facility includes at least one dispensing valve, also known as a production valve, which is disposed on the dispensing line to control the upstream area or production area from the fluid delivered in the dispensing line from the distribution line. The fluid allocation between the conveyed fluid is transmitted to the downstream region. The term "line" is understood herein to refer to one or more pipes, and fluid is conveyed by the one or more pipes to dispensing in a related facility. [0003] The facility according to the present invention includes at least one valve referred to as a discharge valve in a known manner, which is configured to drain the fluid when the downstream demand is slowed or stopped, and any slowing or stopping of the upstream fluid sup...

Problems solved by technology

[0007] Here it is easy to understand the technical problem that arises when defining this safety margin value: if the safety margin value is too high, then a blow-off of the discharge valve will only occur if the parameter in question changes significantly with respect to the value predefined by the calibration. open with the risk of possible damage or destruction of components of the distribution line due to insufficient sensitivity in the control of the discharge valve

[0008] On the other hand, if the safety margin value is too low, the bleed valve will be commanded to open at small variations of the parameter in question with respect to the value predefined by the calibration, with the risk of opening this bleed valve prematurely, and thus with Risk of fluid loss and potential additional costs to the processes implemented by the industrial facility
