BREA, Calif., March 8 -- Simulation Sciences Inc. (SIMSCI), a worldwide leader of advanced process control, optimization and simulation solutions to the global process industries, today announced that it has been awarded two real-time optimization projects with Chevron at one of its refineries. Chevron will utilize ROMeo, SIMSCI's Windows NT based software for on-line optimization, to directly replace their existing on-line, closed loop system on two of the processing units at its El Segundo Refinery. Chevron based its selection of ROMeo on four categories: product features and architecture; product supportability and implementation; technology supplier capability; and maintenance and implementation cost factors. "This project award solidifies SIMSCI's position as a global optimization leader," said Brian Ahern, president of SIMSCI. "ROMeo has quickly become the real time optimization technology of choice, with many on-line systems commissioned and under implementation within some of the largest refining and petrochemical companies in the world." Bob Cuneo, technical manager at the Chevron El Segundo Refinery, said, "We believe ROMeo's optimization capabilities, architecture and end-user friendliness will provide maximum and sustainable benefits for Chevron. This product represents a real technological advancement in real-time optimization technology." About ROMeo ROMeo, SIMSCI's Rigorous On-line Modeling with Equation Based Optimization software is designed to enable plant engineers and management to model process units and optimize operations on a plant-wide basis. The system uses a combination of real-time plant data and current economic objectives to precisely replicate plant operations. Based on a rigorous model of the operating facility, the system calculates optimal process set points for the plant's control system. It also helps determine the location and cause of operating constraints and problems. Unlike older optimization technology, ROMeo uses one model for process simulation, data reconciliation and optimization. This one model concept and state-of-the-art graphical plug-and-play environment minimizes build, implementation and maintenance costs.
