Abstract: A method is described for cold-cutting a lamp having an inner pressure that is lower than the atmospheric pressure and containing a pollutant. The method includes keeping the lamp in position; cutting the lamp at at least one cutting point; prior to cutting, submerging the cutting point in a liquid or pasty composition; keeping the cutting point submerged during the cutting; and suctioning part of the composition into each cut-off portion. The composition is a dilatant and has a temperature no lower than the pour point thereof, prior to the cutting step. After the cutting, the temperature of the dilatant composition is reduced to a temperature lower than the pour point thereof, such as to increase the viscosity thereof and create a sealed stopper.

Abstract: A method of containing a sample of a gaseous mixture flowing in a pipeline at a flow rate, for analysis of same by at least one analyzer of which the operating conditions are not compatible with the physico-chemical conditions of the gaseous mixture in the pipeline is described. The method includes collecting a sample of the gaseous mixture in the pipeline, diluting the collected sample with a dry dilution gas, at a dilution temperature (T_dil) equal to or close to the temperature (T_prel) of the gaseous mixture in the pipeline during the collection step, and conveying the collected and diluted sample out of the pipeline via an outlet pipe for analysis of the same by said analyzer.

Abstract: The invention relates to cleaning equipment for cleaning a tank intended for storing inflammable products and that defines an internal volume (Vint) provided with an opening, this equipment comprising a shutter (1) suitable for closing the opening, a flexible hose (2) that passes through the shutter (1), a trolley (3) sized in order to be introduced into the internal volume (Vint) of the tank, and a cleaning head (4) borne by the trolley (3), connected to the flexible hose (2), and designed in order to spray a cleaning liquid delivered at high pressure by the flexible hose (2). The equipment of the invention also comprises a rod (5) connected to the trolley (3) and passing through the shutter (1), and the trolley (3) comprises a chassis (30) provided with rolling members (300) so as to be able to adopt, in the tank, apposition controlled by an action exerted on the rod (5) in the space (Ext) external to the tank.

Abstract: A method is provided for processing waste and producing methane, in which a chamber is filled with waste, in which it undergoes anaerobic degradation. According to the method, a large chamber and a small chamber are filled respectively with slightly organic waste and highly organic waste, and a liquid fraction generated by the degradation of the waste in the large chamber is introduced into the small chamber. Also provided is an apparatus adapted to implement such a method.
