In 2015 Witteveen+Bos signed a contract with North Caspian Operating Company NV (NCOC) for the Front End Engineering Design (FEED) of a state-of-the-art Water Treatment Recovery Plant, enabling maximised reuse of produced water. NCOC - operating in Kazakhstan and owned by CNPC, Eni, ExxonMobil, Inpex, KazMunaiGaz, Shell and Total - produces this waste water in its main onshore production location, 40 kilometres east of Atyrau in Kazakhstan.
The new Water Treatment Recovery Plant is contributing to the water reuse requirement that is part of a programme on water savings and reuse by NCOC. The objective of this new facility is treating stripped sour water and brine from an existing Water Treatment Plant. A large number of state-of-the-art treatment processes is foreseen to achieve this requirement. The resulting technical water can be used in the demineralised water production. The processes will be housed in a football-pitch sized building heated also by heat recovered from the feed stream.
A significant part of the Witteveen+Bos offices in Atyrau and Deventer are now housing a large multidisciplinary team of engineers from the Netherlands and Kazakhstan. A team of clean water and waste water specialists are intensively working together to develop a high quality engineering package within a very tight project schedule. Aim is to complete the FEED in the summer of this year. The FEED is developed in 3D enabling real life walkthroughs. Safety and reliability studies ensure that a sustainable and safe plant will be realized. With this project Witteveen+Bos is deploying another water reuse design for the industry.
