Presently, DCS is not a just technical tool of control of production units, but it's developed to be placed at the centre of the process as an essential tool for mastering and managing of production units. These technological advances are transforming DCS strategic equipment in plants and companies in general. It's necessary to properly develop and highlight the minimum requirements to be imposed when choosing of DCS, especially for production units of phosphate derivatives having specificities and particular constraints, in order to achieve the required performance and take account of the requirements of the processes operated. OCP has introduced the DCS and their new technologies since 1997 in the production units of Phosphoric Acid and Fertilizers. Now, a perfect mastering of the development of specifications and a confirmed knowledge on the functioning of DCS are certainly acquired by the local skills of OCP. As a result, the need to take benefit and exploit more resources and new features of DCS is logically emerged. This has given rise to development of other increasing axes of improvement in the production units. OCP included two main lines: the opening of DCS to other networks of the Company and the operating fully automatic and smart of production units through the use of advanced controls such as predictive control, fuzzy logic, optimal neural.
