Context

A range of Bürkert products were selected for a new solar power project in Spain to ensure the cleanliness of the process water in order to maintain efficiency and productivity.

The solar-thermal plant uses parabolic-through concentrating solar power (CSP) technology. Parabolic mirrors direct the sun’s rays to a glass collector through which oil flows and gets heated up to around 400ºC.The hot oil is used to turn water into steam which is used to drive a turbine that turns the generator.

In this case the plant has two 50MW generators and the water used in the process is groundwater. All of the impurities need to be removed before it can be used to power the turbine and purified water is also used to clean the mirrors regularly.

Products supplied

To meet the water quality requirements of the solar plant, a treatment process using reverse osmosis was proposed to remove the impurities from the water supply. Bürkert was approached for assistance with the design and implementation of the control system.

The reverse osmosis equipment is designed and manufactured in a skid format that simplifies the installation process and reduces the amount of time required on site.

Efficient data display

Bürkert designers worked closely with the systems integrator to create a simplified yet flexible solution based around the Type 8619 multiCELL controller. One of the key benefits of the 8619, is the ability to deal with up to 6 channels of data, which reduces the total number of displays required throughout the installation.

At the time of the design, the 8619 was the only controller capable of displaying flow measurements as well as analytical data such as conductivity, redox, pH and temperature. The Type 8619 can be configured to display any combination of these parameters depending on the needs of the installation.

Furthermore, once the Type 8619 has been programmed, all the settings can be transferred to a memory card and then uploaded onto any number of similar devices. This project required two identical skids and this feature reduced the amount of time required for the setup of the second skid. This has significant benefits for OEMs, minimising any errors between builds, removing the need for programming technicians for every unit and increasing productivity.

Simplifying the procurement process

Bürkert’s wide range of products was an important factor for the integrator, reducing the number of suppliers and the number of processes required to complete the project.

In all, the project incorporated 12 Type 8619 multiCELL units, as well as 18 Type 8200 probe holders (8200s provide a sealed fixed mount for a range of 120mm analytical probes), used in this instance to measure pH, oxidation-reduction potential (ORP) and temperature. In addition, 16 Type 8030 paddle wheel flowmeters, 36 pressure sensors and 18 temperature sensors were also sourced from Bürkert, along with two pneumatic control cabinets and Type 8640 valve islands.

Once the construction of the reverse osmosis units had been completed, Bürkert offered to help with the commissioning process to ensure that all of its products were operating correctly. In fact, the intuitive design of the Type 8619 and the sensors connected to it, allowed the equipment to be correctly installed and configured by the engineers building the reverse osmosis skids.
