AspenTech features

What does aspentech do?

AspenTech provides software modules and services for modeling, optimization and lifecycle management of industrial processes and assets. Key tasks the software performs include:

• Model-based process simulation for design, debottlenecking and what-if studies
• Advanced process control and model predictive control (MPC) to stabilize and optimize operations
• Real-time optimization (RTO) and scheduling for multi-unit, multi-site production systems
• Asset performance management (APM) including predictive maintenance, remaining useful life (RUL) estimation and failure root-cause analysis
• Manufacturing execution and production planning, including sequencing and constraint-based scheduling
• Data analytics and machine learning applied to process and equipment data

AspenTech products connect engineering models to plant operations so simulation results can be applied directly in control strategies and operational decision support. The suite focuses on high-fidelity physics- and chemistry-aware models rather than purely statistical approaches, while also providing tools for hybrid model development that combine first-principles and data-driven components.

The platform supports industrial workflows from long-term design and planning to short-term scheduling and online control, enabling teams to move engineering insights into production use rapidly. Visualization, KPI dashboards and automated reporting are included to support operator decision making and management oversight.

AspenTech free trial

AspenTech does not typically publish open, self-serve free trials for its enterprise-grade process engineering and APM suites because modules require configuration, engineering data and secure integration to operational systems. Trial arrangements are normally handled through direct engagement with sales and services teams and are organized as proof-of-value (PoV) projects.

PoV engagements are structured to validate a specific use case (for example, MPC on a distillation column or predictive maintenance on critical rotating equipment) and include a short-term license, implementation support and performance metrics to evaluate effectiveness. These proof projects allow teams to quantify benefits before committing to broader rollouts.
