20150184499 | Enhanced recovery of hydrocarbon through supercritical wet combustion, gravity stable in deep heavy-oil reservoirs - Method to enhance the recovery factor by injecting simultaneously or alternately air and water through a well, which is located in the top part of a heavy-oil reservoir showing dip and by producing fluids through a vertical or horizontal well, which is located in the formation lower part, resulting in a gravity stable burning front (GSAI or Gravity Stable Air Injection) at high temperature and pressure. | 07-02-2015 |
20130341933 | System for Generating Electrical Energy from Low Speed Wind Energy by Means of Two Systems of Drive Blades - The invention relates to a system for generating electrical energy from wind energy, said system being characterized in that the design makes use of small air currents and does not require a large amount of air in order to generate electrical energy or power. This system incorporates two generating technologies designed based on the vertical rotation axis concept, achieving movement that is independent of wind direction. The invention combines two technologies, namely: one based on drag forces, ideal for low speed conditions; and another based on lift force, which is best for high speed work. | 12-26-2013 |
20120041240 | METHOD FOR OBTAINING SOLID PARAFFINIC COMPOUNDS BY HYDROTREATMENT OF VEGETABLE OILS - The present application relates to a method for obtaining solid paraffins from vegetable oils and/or animal fats, which is characterized in that the organic oil is preheated to a temperature of between 50 and 100° C. in order to render the oil fluid and for it to be possible to transfer the oil to steps downstream in the method. The oil and the hydrogen are mixed in the pipeline and passed via a furnace in order to be heated to the desired reaction temperature. Inside the reactor, the hydrogen reacts with the oil at the active sites of the catalyst at pressures of between 2 and 11 MPa and temperatures of between 150° C. and 330° C., with an hourly space velocity of between 0.2 and 6 h | 02-16-2012 |
20110301893 | INTELLIGENT TOOL FOR DETECTING PERFORATIONS AND INTERPRETATION OF DATA ONLINE - The present application relates to a tool for detecting perforations in hydrocarbon pipelines based on the sensing system thereof. The function of said tool is to pass longitudinally through a pipeline of specific diameter, monitoring the thickness thereof and detecting any hole over the path followed and, in accordance with the data obtained, establishing the distance at which the holes are located, calculated from the starting point, the time at the instant of detection and also the circumferential position and size thereof, all the aforesaid as part of an online process implemented as the tool progresses through the target pipeline. At the end of the run, the information may be downloaded to a computer where it is available for use and for the corresponding decisions concerning integrity. | 12-08-2011 |
20110146826 | DOSING DEVICE AND PROCEDURE FOR PLUGGING BRANCHES IN FLUID TRANSPORT CONDUITS BASED ON SAID EQUIPMENT - A device and a process reduce losses of fluid in transport conduits, caused by the installation of branches connected directly to conduits. The process includes injecting in the current of the fluid geometric elements of diverse materials and forms, in particular spheres, with densities similar to that of the fluid, by a special doser. The elements are circulated through the fluid, and because of hydraulic effects, the obstruction of the branches prevents or hinders extraction of the product. Recovery of the geometric elements at the end of the conduit uses a filter as a trap. | 06-23-2011 |
20110146043 | TOOL AND METHOD FOR SAFE REMOVAL OF VALVES FITTED IN FLUID PIPES - This invention relates to a manual tool for safely removing undesired taps, connected illegally and controlled by means of locking valves in fluid transport pipes (especially oil and derivatives thereof) and with pressures present of up to 690 kPa (100 psi). The tool according to the present invention is formed by a handle, a handle shaft, a packing gland, a main body, a draining valve, and a gauge adapter or wood plug, which is inserted by friction in the perforation to be blocked, forming a temporary seal therein while a definitive metal patch is fitted and soldered to the pipe. The invention also includes the method for safe removal of valves fitted to fluid pipes with said tool. | 06-23-2011 |
20110143932 | METHOD FOR PRODUCING VANADIUM TRAPS BY MEANS OF IMPREGNATION AND RESULTING VANADIUM TRAP - The invention relates to a method for preparing a chemical composition obtained by co-impregnating water-soluble salts Ba/Mg and phosphoric acid H | 06-16-2011 |
20100300931 | METHOD FOR THE WELL-HEAD TREATMENT OF HEAVY AND EXTRA-HEAVY CRUDES IN ORDER TO IMPROVE THE TRANSPORT CONDITIONS THEREOF - The invention relates to a method for the dehydration of, and in-line removal of asphaltenes from, heavy and extra-heavy crudes. The method is performed at the well head at pressures of between 414 and 689 KPa and temperatures of between 60 and 100° C. and includes two phases, namely a dehydration phase and a deasphalting phase. The first phase includes the addition of solvent, removal of free water, heating, addition of emulsion breakers and settling for removal of emulsified water. The asphaltenes are extracted in the second phase. Said phase comprises the use of low-force in-line static mixers and contactors having a specific design and a sedimentation device with specific internal arrangements for separation. The recovered solvent is recirculated into the method, the improved crude is separated and the asphaltenes are used as fuel for cogeneration which supplies the energy requirements for production and the improvement method. | 12-02-2010 |
