Most oil wells are drilled with rotary method. In this method, a tower holds the drill string, consisting of a series of tubes attached.

The chain linking it to the bank spins rotating in the floor of the tower. The drill bit at the end of the chain usually consists of three bevel gears with hardened steel teeth. The drill is brought to the surface by a continuous circulating fluid system driven by a pump.

Satelsa was present both in the exhibition area and giving sponsors a conference on developments in distributed teams in Mexico in the area of ​​electrochemistry, whose audience was made up of researchers from the SMEQ, who are highly regarded in this area. In the exhibition hall presented Gamry brand innovations, in terms of potentiostat, electrochemical cells and accessories. It was the official presentation in Mexico of the new model potentiostat Gamry Concerning 3000, which was much sought after in the event. Electrochemical cells were to evaluate coatings (cPPT) and the electrochemical test Eurocell solutions with small volume (50 mL). They were also the same brand accessories Gamry as graphite electrodes, calomel reference electrode silver chloride and silver. Finally, we showed two of the most sold brand in Mexico McMillan: the mapping of potential kit and the kit specifically for electrical resistivity soils.

Satelsa, SA de CV, recently participated in the XXIV Congress of the Mexican Society of Electrochemistry, held from May 31 to June 5, Puerto Vallarta, Jalisco, as a sponsor of the event.

Among the various conditions existing in concrete, is that concerning the fissures caused by the increased volume of metal armor as a result of thickening caused by corrosion, which generates traction expansive forces, triggering the dreaded cracking .

To evaluate the degradation due to corrosion of metal embedded in the corrugated concrete against corrosive environments, are used for corrosion test chambers or chambers of laboratory accelerated tests.

Relatio, suppliers of large photovoltaic solar energy systems worldwide, launched a new monitoring system that has been called fieldMonitor and responsive to the problems with solar fields as respect to its control. The solar arrays are increasing in size which brings great difficulties to control their production. Given this situation has developed products aimed Relatio exclusively for large installations whose purpose is to install a monitoring system to manage field production from a single control center.

FieldMonitor comprises an electronic data records and web portal, whose combination enables the system to be controlled solar installations that require more than just a control. This system collects all data received as current and voltage of the series, sunshine, wind speed, temperature of the modules and the environment, the state of investors and investor alarms are recorded and displayed online using software based on the web. Also, when something goes wrong or incorrect data system collects some are automatic alarms and notifications are sent by e-mail, sms, fax, MDA or PDA. In addition the system allows service management through a web portal specific, but linked to the information provided by monitoring for such activities.

Pasteurized Milk is a milk product obtained by subjecting the raw milk to a thermal process temperature and time, to ensure the total destruction of pathogenic microorganisms and almost all non-pathogenic microorganisms.

Pasteurization is generally performed at temperatures below 100 ° C and should be followed by rapid cooling. Always interesting to operate at a higher temperature for a shorter time to, obtaining identical results bacteriological greater degree preserving the original qualities of the product. A liquid acid can be pasteurized at a lower temperature. Pasteurization can be done once the product packaging or prior to this operation. The pasteurization of the packaged product is mainly used for beer, cider, fruit juices and sometimes, wine bottle packaging. Once closed, the bottles are subjected to a water spray getting hotter, to 65-75 ° C, and kept at this temperature for a time ranging from twenty to thirty minutes, and finally cooled in water increasingly colder.

For thousands of years, ethanol has been produced for human consumption and also for thousands of years, it has been possible to concentrated alcohol by distillation.

Today, they are looking to produce ethanol from carbohydrates such as sucrose or starch.

World production of cement has a high specific emissions of CO2 (about 0.9 kg CO2 per kg of clinker) with a 5% contribution to global emissions of anthropogenic CO2. These emissions can be reduced substantially by using solar energy in the thermal decomposition of lime, which is the main step endodermal cement production.

CaCO3 CaO + CO2 = 178 KJ / mol (T = 900 ° C)

This reaction is highly endodermal (DH ≈ 477 kWh / ton CaCO3) which is why the cement industry requires high thermal energy input (approx. 0.9 kWh per kg of product). As a result, it may make sense to integrate solar thermal energy in industrial production of cement, based on cyclonic type reactors located in the center of Central Receiver System. This reactor can be opened to the atmosphere (no window open) since the calcination reaction can occur in air and the effective absorption of concentrated sunlight can be achieved by forming a cloud of gas and particles found inside turning the reactor cavity.
