Yokogawa wins control system orders for large thermal power and desalination plants in Qatar

Posted: Wednesday 17th February 2016

Samsung C&T, Acciona Aguaplace and Hitachi Zosen Corporation place orders in projects for Umm Al Houl Power.

Yokogawa Electric Corporation has received orders to provide control systems for thermal power and desalination plants that are to be constructed for Umm Al Houl Power, a Qatari company whose main businesses are power generation and water desalination.

The control system orders for a thermal power plant and a reverse osmosis desalination plant were placed by Samsung C&T and Acciona Agua, respectively. Yokogawa also received an order placed by Hitachi Zosen Corporation for a control system for a multi-stage flashing system desalination plant.

These plants are being built for Umm Al Houl Power at a location 20 km south of Doha, the capital of Qatar, and the power and water produced there will be provided to the Qatar General Electricity and Water Corporation (Kahramaa) for a period of 25 years. The capacity of the power plant will be 2.4 GW and the combined daily capacity of the two desalination plants will be 590,000 m3. These plants are scheduled to commence providing electricity and water in 2017.

The power plant will use a combined cycle power generation system (A power generation system that makes combined use of gas and steam turbines. This highly efficient system recovers the exhaust heat from a gas turbine and uses that to produce steam that drives a steam turbine, thereby generating additional electricity from the same heat source.).

One of the desalination plants will use a reverse osmosis process (A system that relies on the application of pressure to seawater. This forces the water, but not the salt, through a semipermeable membrane, thus desalinating the seawater), and the other will rely on a multi-stage flash distillation process (A desalination system that heats and evaporates seawater in vacuum distillation tanks and then condenses the steam to produce fresh water. This system is highly energy-efficient because it uses the heat from steam created in multiple vacuum distillation tanks.

For this project, Yokogawa will deliver the CENTUM® VP integrated production control system and the ProSafe®-RS safety instrumentation system. In addition to being responsible for engineering, the company will provide support for the installation and commissioning of these systems. The CENTUM VP system will be able to monitor and control operations at all three plants.

Yokogawa won these orders because the following points were highly evaluated by the end user and the companies that are building these plants:

· The engineering capability that Yokogawa demonstrated in the Ras Abu Fontas A2 desalination plant project for QEWC

· A solid global track record in executing large combined-cycle power plant projects

Qatar has the world’s third-largest reserves of natural gas, and demand for electricity and water is soaring in line with the country’s rapid economic growth. The power and desalination plants that are being built for Umm Al Houl Power will make up an important part of Qatar’s infrastructure. Backed by these orders, Yokogawa will continue working to expand its control business in the power and water infrastructure market.
