Global software developer and integrator Yokogawa Marex of Cowes UK today
announces the worldwide rollout of its uniquely powerful ExaspotTM
open standards real time plant optimization system. Based on the state-of-the-art
Shell Process Optimization Technologies (SPOT) program suite for closed-loop
process optimization, Exaspot combines real time plant data with economic objectives
to replicate and optimize plant operations.
Optimization is applied to a functional unit, typically a high-value section
of a large plant or refinery, where small changes to operational conditions
can result in large savings. The purpose of Exaspot is to maximise unit margins
within operational, technological and economic constraints. By measuring optimizer
performance in terms of economic value, users are provided with the profit generated
for each unit run, with the aim of maximising economic performance -all with
perfect traceability.
Exaspot development
Exaspot is a triparty development utilising the unique skills and expertise
of Yokogawa Marex, Shell Petroleum and Shell Global Solutions International
(SGSI). Perfected over an 18-month development period, Exaspot provides configuration
tools and application programs to merge all software seamlessly. Exaspot software
packages include:
- Yokogawa Marex Exaquantum OPC global industry standard data historian
- Shell PROMOTE process simulator incorporating Shell's refinery database
and conversion models which is used for rigorous process modelling
- Data reconciliation engine (DATACON)
All optimizer run-based data is available for analysis through online analytical
processing (OLAP). Client reporting offers standard multi-dimensional views of
optimizer data. Users can create their own views and store them into a shared
library.
Key features
Exaspot's Process Control Systems -interface enables OPC compliant
communication with process control systems (PCS) offering Data Access (OPC DA2.5a)
text file-based communication (ASCII CSV) is also supported.
In addition, the following features are offered: spreadsheet based configuration
tool creating Exaspot and relational database (RDB) configuration settings including
definition of optimizer tags and their related functionality; steady state analysis;
unit configuration check analysis; external system status analysis; automatic
reconciliation; optimizer/operator interfacing and setpoint download; storage
of optimization data for OLAP analysis; web reporting; rule based generation
of mass balance, economic balance and laboratory reports; ability of Exaspot
applications to work offline; and automatic plant model simulation (APMS).
APMS is a derived functionality from the Shell PROMOTE process simulator models
being run to produce three process business cases: the 'Rating' case calculates
process parameters such as heat transfer coefficients. The 'Base' case represents
the model in the predictive mode where the control strategy is included resulting
in the process biases being calculated.
The 'Optimization' case is similar to the base case but with the inclusion of
economic optimization by varying independent variables. The output of this case
is a set of independents or setpoint values for multivariable controls and/or
DCS applications.
Exaspot around the world
Exaspot has already proved its business case in large installations
around the world. In Singapore at Shell Bukum, Exaspot is performing as a stand-alone
maximizer in a large refinery. In Thailand, Shell and Yokogawa have jointly
installed an Exaspot facility at Thai Aromatics, and at Petit Couronne in France,
Shell Global Solutions International (SGSI) has installed an Exaspot suite in
a large industrial plant, where the administration and server hosting and location
services are provided by SGSI at a remote location, in this case Holland. Shell
intends to expand this capability further, anticipating worldwide site data
being held and analysed at a single location in Holland.
The flexibility of the product is demonstrated by these varied installations;
the core Yokogawa Marex product at the heart of Exaspot, its world recognised
Exaquantum plant information management system (PIMS), has been installed in
over 200 plants worldwide. Exaquantum is the essential cornerstone plant information
function in Yokogawa's Visa plant optimization product and is the core technology
in the Yokogawa Enterprise Technology Solutions (ETS) concept.
Nigel Bowden, Yokogawa Marex Managing Director, adds: "Exaspot is an excellent
example of industrial cooperation. Our leading software specialism, allied to
the real time data from Shell and the hydrocarbon integration flair of SGSI,
have given us an outstanding product that will take us, and the processing industry,
well into the millennium. Exaspot is a new century product: not just process,
not just control, it cuts right to the heart of the business. Not just efficiency,
not just economy, but best added value. Best profit. "
1. Yokogawa Marex is a world leader in information management systems for
process industries. The company provides a systems development and integration
capability specializing in integrated information systems for process industries
throughout the world.
2. The Yokogawa Exaquantum Plant Information Management System (PIMS) delivers
benefits for plant operators in many process industries in most parts of the
world. Yokogawa PIMS integrate data from many systems in a plant and produce
high value business information for use by decision makers at all levels of
the enterprise. Yokogawa PIMS automatically integrate data from process control
systems, including Distributed Control Systems (DCS) and Programmable Logic
Controllers (PLC), with other data from quality, maintenance, laboratory, planning,
scheduling, Enterprise Resource Planning (ERP) and many other systems. Yokogawa
PIMS convert Plant Data into Business Information.
3. The Yokogawa software being installed today is already in use in chemicals,
food, petrochemicals,
oil & gas, pharmaceuticals, power generation and general manufacturing throughout
the world, providing monitoring, management, optimization modeling and control
of many diverse, dynamic, and hazardous processes.
