AKO in Menasol 2012

AKO attended Menasol 2012, the 4th North Africa & Middle East Solar Conference & Expo that took place this week in Abu Dhabi and organized by CSP Today. If you were not there, here you´ll find some of the highlights we have gathered for you.

And we start with this statement: The MENA region, Middle East and North Africa, is now welcoming CSP technology as a way to free itself from fossil fuels dependency. 

According to a study commissioned by the World Bank:“MENA’s oil-producing countries are embarking on CSP investment programs to free-up oil and gas from the power sector for higher value-added uses and exports, and in the longer term for CSP energy export”.

Nature has given this region the right elements for energy production. Up until now oil was the most important source of revenue, but this natural resource is not limitless. Each country has its own reasons to turn to solar power. South Arabia is betting on 25GW of CSP by 2032 hoping that solar energy will allow them to keep a nice oil reserve for its exportation. Jordan, on the other hand, wants to produce its own energy, from solar, to reduce oil imports.

Obviously European countries are more than glad to see this policy change happening, showing their willingness to promote this transformation to depend less on oil, for both economical and environmental reasons, with projects like DESERTEC.

In any case, CSP technology seems to be the way to go for all these countries.

What s our final conclusion? There is a long and bright future ahead of us, as the providers of AKOTRACE®, the most used Electrical Heat Tracing solution worldwide in CSP plants. And we are more than ready to be part of this transformation taking place in the MENA region.

Optimal installation of the Electrical Heat Tracing System (II)

We continue with the series of post we started a few days ago about the electrical heat tracing elements installed in the field.

This time we are going to focus on wiring junction boxesbrackets and how to audit the installation to ensure optimum plant´s performance.

Junction boxes and brackets

The junction boxes, used to connect the heating cables or the temperature probes, must be installed in a way that facilitates its access, but, at the same time, they should be protected from rain and must avoid excessive mechanical exposure. Extra protection should be added when the boxes are installed in an area classified as explosive atmosphere.

About the brackets used for the boxes set up, (and installed over the surface where it is necessary to control the temperature) we should take into account that they could cause additional thermal loss, meaning that this point could get cooler. Depending on the situation it would be convenient the use of an additional heating cable extension to compensate for possible thermal losses.

Compliance checks and installation logs

Installation inspection is carried out in two phases: The first one takes place after the installation of the heat tracing system and before lagging.

At this time we have to make sure that all the materials used are undamaged and that the installation complies with the established requirements.

We should take into consideration that any intervention in the electrical heat tracing system after lagging requires its removal, that´s why all the necessary checks have to be made before. This is a critical reminder since any mistake detected can be easily corrected at this point, but after lagging, the costs of any repair just skyrockets.

Among the most important checks we should pay special attention to the installation of the heater and its probes, making sure that all elements are fixed correctly, properly labeled, and, most especially, they should comply with the project requirements.

That´s what AKO has learnt over years of research and multiple installations, the kind of experience that have made our AKOTRACE® solution the most trusted and used electrical heat tracing system worldwide.

AKO will lead the EHT of the CSP plant La Africana

We continue sharing with you more good news.

AKO has been awarded with yet another CSP assignment. This time we are going to lead the Electrical Heat Tracing project of La Africana, a CSP plant located in Córdoba, South of Spain.

La Africana is led by the undertakings TSK, GRUPO ORTIZ and MAGTEL and promoted by the engineering firms INGEMAS and IDOM.

The plant uses parabolic trough collectors for 168 loops. Its main feature is its capacity to store energy using molten salts and solar racking, making it capable of supplying electricity currently consumed by around 30,000 Andalusian households.

Our main goal in this project will be to ensure the criticality of the Electrical Heat Tracing in this kind of plants, how? By means of our AKOTRACE® solution that will:

  • Guarantee the circulation of the molten salt fluid at high temperatures
  • Prevent non-desired stoppages of the facility
  • Provide our technological heater proposal for pumps and valves
  • Provide our control and monitoring system.

We are honored to be part of this project and we´ll make sure to share with your our progress in future posts, the same way we did with Torresol & Sener´s Gemasolar  and Valle1 &Valle2
