Abstract: A process and a device for determining the volume of liquid remaining inside a flexible pouch provided with means for dispensing the liquid to be consumed comprises placing the pouch inside a rigid envelope filled with a known volume V1 of a first measuring liquid having an electrical conductivity C1, during the dispensing of a volume VA of liquid to be consumed, admitting inside the rigid envelope the same volume of a second measuring liquid present outside the rigid envelope and having an electrical conductivity C2 different from the electrical conductivity C1, measuring the electrical conductivity CM of the mixture of the measuring liquids present inside the rigid envelope, determining the volume VA of liquid to be consumed which has been dispensed from the measurement of the electrical conductivity C3, and calculating the volume Vr of liquid to be consumed remaining inside the pouch from the volumes Vi and VA.

Abstract: A device for installing and handling a module of a subsea processing station, comprises a frame, and a hydraulic system comprising hydraulic cylinders each comprising a cylinder body, and a piston intended to be put into contact with a foot and movable inside the cylinder body between a first mechanical abutment corresponding to a deployed position of the piston and a second mechanical abutment corresponding to a retracted position of the piston. The piston divides the internal volume of the cylinder body into a first chamber and a second chamber. The first chamber is supplied with hydraulic fluid by two independent hydraulic circuits comprising a shock-absorbing circuit able to move the piston between the deployed and intermediate positions located between the deployed position and the retracted position defined by a hydraulic abutment, and a controlled-lowering circuit able to move the piston between the intermediate position and its retracted position.

Abstract: The present invention is a filtration system and a method for cleaning a filtration system. The filtration system comprising a hydraulic circuit Cp recycling the permeate stream to the feed side of the membrane and/or a hydraulic circuit Cr recycling the retentate stream to the feed side of said membrane. The method injects an amount of a chemical product into the filtration system in the hydraulic circuit Cp or in the hydraulic circuit Cr or upstream of the cross-flow filtration membrane, setting the proportion of recycled permeate stream or recycled retentate stream collected in the hydraulic circuit Cp and/or Cr to enable the recycling of a significant amount of unreacted chemical product having passed through the cross-flow filtration membrane to the feed side of said cross-flow filtration membrane.
