摘要： A device for removing misalignments between flanges of pipeline ends. More specifically, a device that, operated by an ROV, allows flange holes at the ends of subsea pipelines to be aligned so that interconnection operations between said pipelines can be embodied. To this end, the device described herein comprises an elongated metallic body having at least two diameters and presenting a gradual reduction between the component diameters. Additionally, a fixed nut is mounted on the larger diameter side of the elongated body, followed by a manipulator for administration by the ROV. On the other hand, a movable nut is mounted on the smaller diameter side of the elongated body, and the tightening movement made by the ROV on this movable nut causes the device to pass through the holes to be aligned, precisely, in the direction of the larger diameter of the device of the invention.

摘要： The present invention relates to a process for capturing CO2 on a large scale using aqueous solutions of zwitterionic bases by contacting a gas stream containing one or more acid gases with said solutions. The internal salts obtained in the present invention have the advantage of not being volatile, being less susceptible to chemical and thermal decomposition, and also have lower absorption enthalpy. The present invention can be used in various industry sectors, such as in the energy sector, for capturing CO2 from exhaust gases, in the chemical sector, for removing CO2 from the gas streams of catalytic processes in which the CO2 can poison the catalysts, and, in particular, in the oil and gas sector, for purifying natural gas.

摘要： A lance applicable to a boiler burner, the lance presenting a rigid shape. By means of the device disclosed herein, it becomes possible to carry out maintenance, assembly, disassembly and replacement of oil lances for boiler burners that are operational in places with limited space. The lance provided by the present utility model comprises a modular structure consisting of rigid elements, which allows achieving a correct positioning of the burner nozzle using this lance in relation to the boiler. Consequently, it is guaranteed that the boiler operates under ideal operating conditions, once the burning in the burner portion is controlled. For this purpose, the device disclosed in the present utility model comprises a hexagonal bar that provides the interconnection of a first tube to be interconnected with a second tube of greater diameter, wherein between the first tube and the second tube the arrangement of a sealing gasket is provided.

摘要： The present invention was designed as a technological package capable of implementing the removal of up to 30 cm of biofouling, normally originating from sun coral, on support vessels of ships and oil platforms, without the need for help from divers. The integration of the solution consists of a robotic platform containing a robot for flat areas and a robot for recessed areas, which sends the waste originating from the removal, capturing and crushing to a modular waste-treatment system (MSET). The operations center enables the functioning of all of the integrated systems, being housed in a support vessel, which also has a system for automatically launching and recovering the robot, the control of the robotic platform containing a software architecture capable of allowing the operator to view, plan and record the missions.

摘要： The present invention deals with a catalyst for converting CO by the reaction of water gas shift at high temperature, free of chromium and iron, consisting of alumina promoted by potassium and zinc oxide. The catalyst prepared in this way maintains a high CO conversion activity, not having the environmental or operating limitations with low excess steam in the process, which exist for state of the art catalysts. Such a catalyst is used in the process of producing hydrogen or synthesis gas by steam reforming hydrocarbons, allowing the use of low steam/carbon ratios in the process, presenting high activity and stability to thermal deactivation and lower environmental restrictions on production, storage, use and disposal, than catalysts used industrially based on iron, chromium and copper oxides.
