INEOS Improves Heat Exchanger Performance—
Saves Millions in the Process

By Sanjeev Mullick, Product Marketing, AspenTech

INEOS, a leading European crude oil refiner, has successfully employed Aspen HYSYS® and
Aspen Tasc+™ to monitor heat exchanger fouling and optimize their cleaning procedures.
The result is more predictable and reliable operations, leading to savings of $4MM per year.

Heat exchanger fouling in the vacuum distillation unit (VDU) was affecting operational
performance by limiting capacity and increasing energy consumption. To address this problem, INEOS implemented an automated fouling monitoring application based on rigorous models.
They were able to accurately simulate fouling behavior using Aspen HYSYS and Aspen Tasc+,
and integration with Microsoft® Excel enabled easy visualization of results. The application
allows INEOS to assess various cleaning scenarios to fully optimize production efficiencies.
Benefits include:

  • $1.5–2MM annual savings per VDU; $4MM/yr total savings
  • Enables INEOS to implement cleaning solutions as needed to optimize production
  • Ensures more predictable and reliable operations
  • Integrates easily with other systems for deployment at plants worldwide
INEOS has since expanded the application to include the crude oil distillation unit (CDU). Click here to read the complete case study.

INNOVATION WATCH

Rate-Based Modeling of CO2 Capture with Amine Solutions

By Dr. Chau-Chyun Chen, VP Technology, and David Tremblay, Product Manager, AspenTech

Rising energy prices coupled with a higher environmental consciousness have generated renewed interest in ways to successfully capture and store the Carbon Dioxide (CO2) produced by traditional power plants and new coal gasification plants. For example,Mono Ethanol Amine (MEA),Methyl Diethanol Amine (MDEA), and activated Tri Ethyl Amine (TEA) solutions are being considered by the industry as viable ways to capture CO2.

AspenTech and the University of Texas at Austin recently conducted a joint simulation study using Aspen RateSep™ to simulate UT-Austin pilot plant data for CO2 capture with queousMEA.

The superiority of rate-based model predictions over equilibrium-stage models was clearly demonstrated. In addition, the study also examined the impact of various rate-based modeling techniques such as film discretization, flow mixing, and interfacial area correlations. The model results have been further validated against additional publicly reported industrial data. This investigation provides the following key insights:

  • CO2 absorption withMEA is reaction rate controlled in the liquid film
  • CO2 absorption withMDEA is mass transfer controlled in the liquid film
  • CO2 absorption with activated TEA is chemical equilibrium controlled in the bulk liquid

Aspen RateSep extends the functionality of Aspen Plus® by providing second-generation, rate-based technology. It encompasses all critical process modeling fundamentals for CO2 capture with amine solutions, providing a comprehensive, robust, and predictive processmodeling framework for industrial process development and design.

Special Report: Consider Integrated Plant Design
and Engineering

By Sanjeev Mullick and Vikas Dhole, AspenTech Originally appeared in Hydrocarbon Processing, December 2007

Significant global economic growth has spurred investments in new plants and expansions,
thus leading to increased engineering activity worldwide in oil & gas, refining and
petrochemicals. As a consequence, process industries are facing threemain business challenges:

  • Executing projects efficiently with fewer engineers
  • Faster turnaround on projects to bring assets onstream more rapidly
  • Recruiting, training, and retaining engineering talent

To meet these challenges, owner-operators, licensors, and E&C firms must:

  • Streamline workflows to improve efficiency and execute projects faster
  • Enable rapid learning through easy-to-use and integrated toolsets
  • Ensure reuse of information and knowledge across the lifecycle—breaking down traditional organizational barriers

With the help of several customer case studies, this special report from Hydrocarbon
Processing
illustrates how leading companies are applying these best practices in support of
model-centricity, data-centricity, and concurrent engineering to achieve new levels of
operational excellence.

The Role of Chemical Engineers in Green Engineering

By Mike Mendez, Senior Business Consultant, AspenTech
Originally appeared in Chemical Engineering, December 2007

We all want clean air and a healthy physical environment. Historically the principal, and
sometimes only, criterion for process design or process selection has been an economic rate
of return. Tighter and more restrictive policies have raised guardianship of the environment to
levels of importance matching (and at times even exceeding) economic fervor.

Our profession bears great responsibility in designing plants that are economically viable and
gentle on the environment. This responsibility presents both challenges and opportunities.
Often challenged are those engineers unprepared to rapidly design and cost-estimate large
numbers of process options. Conversely, engineers who are well prepared to handle these
massive tasks in a timely and efficient manner are rewarded by the opportunities.

Green Engineering is a term often used due to concerns about the effect human activity is
having on the environment. As explained by chemists and biologists, Green Engineering
concerns production of energy and material goods starting with green raw materials such as
microorganisms, plants, and biomass.

We are pleased to present a new technical brief that describes how chemical engineers can
use AspenTech’s software tools to accelerate analysis and consider a large number of complex solutions in support of Green Engineering goals. A brief outline of tools such as steady-state
and dynamic process simulation, pinch analysis, column targeting, advanced controls, and cost estimation—used to design better and more energy-efficient plants—is provided in this article.

Advances in Front-End Engineering Workflow
and Integration

By John Griffith and Drew Dietrich ofWorleyParsons Engineering, and Siva Natarajan and Ron Beck of AspenTech
Originally appeared in Hydrocarbon Engineering, January 2008

WorleyParsons, the 11th largest worldwide process E&C firm, has successfully employed
Aspen Zyqad™ over the past six years on a range of engineering projects of increasing size. Use of this solution has had enterprise-wide benefits in terms of project quality, execution time, and global access to available engineering resources for projects.

A globally consistent Computer Integrated Projects (CIP) approach to engineering and design
has proven invaluable as E&C firms become more resource constrained. Thus, WorleyParsons’ approach to project execution has positioned the organization to effectively deploy “aroundthe-
clock” engineering using offices around the globe. The CIP approach also facilitates
electronic hand-off of design data fromWorleyParsons to client owner-operators for project
lifecycle management. As Phase I of the integration plan is completed,WorleyParsons will
continue to expand the scope of CIP to include all phases of the project from conceptual
engineering to operations and maintenance.

This paper further describes WorleyParsons’ worldwide implementation of Aspen Zyqad.
