APPARATUS AND METHOD FOR FACILITATING A HYDROSTATIC PRESSURE INCREASE IN A FLUID FLOWING IN A PIPE

摘要

There is described an apparatus (1) and a method to facilitate a hydrostatic pressure increase in a fluid flowing in a first pipe (22) where the hydrostatic pressure increase is provided by means of a pumping device (3) being supplied with energy the apparatus including:- an energy harvester (5) arranged to be able to draw a portion of an energy carried by a fluid flowing in a second pipe (28); and - a mechanical or hydraulic energy transfer device (9 60) arranged to be able to transfer a portion of the energy absorbed by the energy harvester (5) to the pumping device (3).
