摘要： The present invention describes a plasma reactor for processing natural gas and/or light hydrocarbons, including biomethane and biogas, with a plasma torch that does not require the use of cathode shielding gas (shielding gas), as well as a process for reforming using a plasma reactor for the production of synthesis gas and carbonaceous materials from natural gas and/or light hydrocarbons.

摘要： The present invention proposes a system for measuring the water-oil interface level based on the fluid thermal properties. To overcome limitations related to the interface level in oil separation processes, an interface level sensor must detect water, oil, emulsion and foam layers. Furthermore, maintenance costs must be low and the time between maintenance must be high, in order to obtain high production rates and more reliable control of the oil separators.
Optical system for measuring the water-oil interface level from fluid thermal properties comprises single-mode optical fiber (1), FBG (2), PTFE tube (3), connection (4), flange (5), optical connectors (6) and optical interrogator (7).-

摘要： The present invention addresses to a system that aims at reproducing situations close to those found in oil wells, in relation to the thermodynamic conditions (pressure and temperature), and the fluids present (by means of the chemical species involved), aiming at representing in a more realistic way the production scenarios to be faced. The main scope is to represent on a laboratory scale the phenomenon of depressurization with the release of carbon dioxide inducing the precipitation of calcite (calcium carbonate), the growth and agglomeration of inorganic crystals, and the phenomena of adhesion and scale on common metallic surfaces of elements of completion of oil wells.
