The plant, which is a joint venture between Saudi Aramco and Sumitomo Chemical Company (Japan), will start operations in the third quarter of 2008.

The plant information management project integrates best-in-class technologies into a unified system using Invensys’ InFusion infrastructure. InFusion’s object- and service-oriented technology enables access to the real time data from the process and utilities units and easy integration and transfer of data between applications to provide a seamless and scaleable information system. InFusion interfaces will facilitate integration with SAP modules.

The current system scope includes an integrated solution comprising Real Time Data Base and Historian, Laboratory Information Management System (LIMS), data reconciliation, plant-wide material balance and production accounting, alarm monitoring, emissions monitoring, and performance management, with more modules planned for the future.

The proposed solution consists of best-in-class technologies available in the market, including Invensys’ new Material Balance Module for unit material balances and data reconciliation unified with InFusion technology. The Material Balance Module lets engineers efficiently evaluate volume and mass balances on-line, enabling them easily to improve data quality and reliability, which forms the basis for process analysis and improvement.
