New SimSci-Esscor ROMeo Refinery Software from Invensys Enables Refinery-wide Process Modeling and Optimization

Industry-leading ROMeo software leverages proven reactor modeling technology from ExxonMobil Research and Engineering Company

NOVEMBER 03, 2010/PLANO, TEXAS – Invensys Operations Management, a global provider of technology systems, software solutions and consulting services to the manufacturing and infrastructure operations industries, today announced the release of its SimSci-Esscor® ROMeo® Refinery software solution, which enables refinery-wide process modeling and optimization as a component of the InFusion Enterprise Control System (ECS). The new software extends the company’s powerful ROMeo optimization software using a complete set of rigorous kinetic reactor models, under license from ExxonMobil Research and Engineering Company (EMRE).
The new ROMeo software can help refiners achieve Productivity and Control Excellence because it allows them to improve crude selection, evaluate crude supply opportunities and reliably predict refinery yields and qualities to determine the potential for improving yields of higher-value products and processing lower grades of crude.
“This latest release of our ROMeo Refinery software allows refineries to rigorously simulate and optimize the entirety of their operations in detail, from the crude oil tank farm to final product blending,” said Harpreet Gulati, product director, Invensys Operations Management. “With clear, measurable and visible benefits that can total millions of dollars per year, companies can utilize a ROMeo solution to get a complete understanding of the true profitability of their refineries, as well as understand the interaction between upstream units that have downstream constraints.”
The ROMeo refinery software offers:
• A scalable software solution that allows incremental, expandable deployment within a common architecture, helping to ensure rapid return on investment.
• Refinery-wide modeling to identify the most profitable processing of different crude oil feedstocks, which can help ensure the highest-value product pools.
• Re-use of individual unit models for performance monitoring or online optimization of individual units and distillate pools.
This release of the ROMeo Refinery software incorporates EMRE's rigorous kinetic models, which enable detailed modeling and optimization of FCC, reformer, HF alkylation and sulfuric acid alkylation units. Additional models for hydrocracking, fuels and lubes hydrotreating, coking, isomerization, visbreaking and other units will be available in the near future. All models are available in open equation format, enabling quick and robust modeling inside the ROMeo Refinery software environment.
The ROMeo Refinery software is based on Invensys Operations Management’s proven ROMeo optimization suite. ROMeo software technology provides a common platform to optimize other aspects of refinery profitability, such as refinery-wide mass balance, utilities optimization, naphtha management and hydrogen optimization. Its baseline features can act as a springboard for additional functionality, such as Wonderware® Intelligence, an enterprise manufacturing intelligence product that can be layered on top of existing ROMeo installations to create dashboards and monitor KPIs.
