Essent Projects B.V. is currently busy with the conversion, renovation and extension of the Clauscentrale on the instructions of Essent Energie Produktie. This power station is converted from a basic load to a peak load station. One of the existing turbines (Claus B) is being converted into a steam turbine and the power station will be extended with a new unit (Claus C). Once the extension and conversion have been completed the combined capacity will be 1,450 MWe, excluding Claus A (640 MWe).
Evilim Industriewater BV was approached by Essent Projects B.V. in January 2011 within the context of this conversion for the supply of a temporary demineralised water facility to support the chemical cleaning process for the new boiler plant (Claus C) and the start-up of the turbines.
Essent opted for a temporary plant with a capacity of 80 m3 /hour and for conductivity of the exiting water lower than 5 µS/cm. It will use its own water sources for feed water.
In order to be able to realise this project Evilim, in accordance with the joint venture agreement between Evides Industriewater and WML, looked to cooperate with Evides Industriewater (mobile RO units or MROs), Logisticon (sand filters) and P Kwadraat Technische Ondersteuning (generators, on-site works foreman, everyday operation and malfunctions service). This cooperation finally resulted in a quotation being submitted to Essent which was subsequently accepted.
The plant, which among other things consists of 3 sand filters and 4 mobile RO plants, had to be handed over, ready to operate, at the beginning of March 2011. Thanks to good cooperation and making clear agreements the plant was actually handed over at the beginning of March. The plant has worked satisfactorily since March and the chemical cleaning was completed mid June.
Essent also wanted to have a backup plant for demineralised water available during the test phase of its own new demineralised water plant. The temporary plant is ideally suited for this and is now being used for this purpose. However, in order to supply the required conductivity of < 0.1 µS/cm, the plant was extended in July with four mixing beds (BW&T) that also have a capacity of 80 m3/hour.
Communication between the various parties was of great important in realising this project to the client's satisfaction. Given the time pressure on the project – order January, start supplying the beginning of March – the various parties had to work and cooperate very closely with each other in a very pragmatic way.
Evilim Industriewater BV, in cooperation with all the other parties, was ultimately successful in being able to offer a good temporary solution to the client, Essent Projects B.V. Evides Industriewater’s MRO fleet consists of 12 units with a total capacity of almost 1,000 m3/hour.
