i-Steam™ is a software developed to model, simulate and optimize steam and power systems. i-Steam™ uses non-linear modeling and optimization algorithms to improve the operating conditions of existing utility systems to reduce energy demand and increase profitability. Capable of revamp projects with different level of investment and complexity, i-Steam™ has been successfully used in many projects for both investment-free optimization and revamps.
|Investment Free Optimization Projects
|Identify the best operation strategy for site utility system. Typical operating cost savings are 2-5% of the total CHP operating cost for oil refineries.
|Identify inefficient infrastructure points in an existing steam systems and develop the most sustainable solutions by removal of inefficiencies.
|New Design of Utility System
|Perform automatic design of cost-optimal process steam driver network.
User-friendly interfacei-Steam™ has an easy-to-use graphical interface which contains a range of unit operations and design tools for utility systems.
Modeling and simulation of utility systemsi-Steam™ comes with a series of built-in unit models, covering all major equipment components of the utility system. With its drag and drop environment, a user can easily create a network model by adding unit blocks and stream connections.
Driver selectioni-Steam™ is capable of selecting the optimum configuration of steam turbine drivers under various operating scenarios. Based on an MILP algorithm, i-Steam™ can quickly generate several steam system configurations for further comparison and analysis.
Model ComparisonsModels with different configurations and operating conditions can be compared using the Model Comparisons Module. All parameter and calculation comparison results can be exported to Microsoft Excel for further analysis.
Comprehensive modeling and simulation: CHP + Steam Pipeline + ProcessesA user can build detailed hydraulic models for steam pipeline systems. In addition, a user can combine CHP, pipeline and process steam generators/users together in one single system. This type of comprehensive models is realistic and provides more accurate predictions of the performance of a system.
Targeting and graphical analysisi-Steam™ contains a site targeting tool to find energy performance targets, and a graphical analysis tool for steam distribution comparison among various scenarios.
Performance regression toolFor critical unit operations and equipment, such as boilers and steam turbines, i-Steam™ provides a performance regression tool to obtain accurate performance models for individual equipment based on operational records.
Large scale optimization
Based on a unique non-linear utility system modeling and optimization approach, i-Steam™ is able to optimize with a wider variety than other commercial packages:
More realistic models for existing utility systems: CHPs = Pipelines + Processes
Optimization for steam driver configurationsThis module helps to determine the optimal configurations of process steam drivers with multiple operating scenarios. Also, the user is able to generate different steam network configurations quickly and effectively.
A platform for conceptual design of utility systemsi-Steam™ can be used for conceptual designs for utility systems. Deliverables such as PFDs and steam balance spreadsheets can be exported from i-Steam™. It reduces time and effort for manual data input and handling, as well as reduces chances of making mistakes in handling data exchange among different software/tools.
