Abstract: An apparatus and related process for the internal cleaning of a pipeline includes an interchangeable rotary cleaning head, a motor device coupled to the rotary head, a movement device configured to move the apparatus inside the pipeline, and a remote control system. The combined movement of the rotary head rotation and of the advancing motion of the apparatus inside the pipeline allows the disintegration of the deposits present internally of the pipeline by mechanical action.

Abstract: There are a device and a method for coalescence separation for a fluid having at least two phases at least partially immiscible with each other and having different specific density or gravity. The separation device has a plurality of sheets or trays that are spaced apart from one another to form passage channels that slow down and divert the flow favouring the coalescence separation.

Abstract: A process to identify a representative sub-sample of a rock sample includes the following steps:



digitally acquiring at low resolution first 2D or 3D images of the rock sample, and by a recomposition of the first images along a direction representing a digital sample;
subdividing with a volumetric subdivision the digital sample defining 3D digital blocks having a volume of substantially similar value;
analysing each 3D digital block on the basis of key points or texture descriptors obtained elaborating the first images on the basis of the properties or structures of the rock, identifying two or more homogeneous classes of 3D digital blocks, each homogeneous class defining a portion of digital sample having 3D digital blocks equivalent to each other as to the technical characteristics of the rock; and
selecting at least one representative block for each homogeneous class identified, locating and extracting a sub-sample from the rock sample.
