A Brief History of the IECMA Brief History of the IECM

• Period I: The Dark Ages (1983 ~1991)

• Period II: The Renaissance (1992 ~2001)

• Period III: The Modern Age (~2002 – present)


Period IPeriod I

• IECM conceived as a way to help DOE/PETC evaluate R&D priorities for “high risk, high payoff” technologies to mitigateacid rain—focus on coal-fired power plants

• Provide a framework to systematically analyze and compare options for pre-combustion (coal cleaning) and post-combustion control of SO2 and NOx

• Initial work focused on advanced coal cleaning processes, combined SO2 /NOx removal processes (e.g., copper oxide, NOXSO, electron beam), and duct/furnace sorbent injection

• First computer models coded in the Demos (now Analytica) modeling environment running on a central VAX computer

15


Period IIPeriod II• Rapid growth in use of desktop computers and laptops

• Major new effort to develop the first graphical user interface (GUI)—made models accessible without expert knowledge of computer programming languages

• Modeling of PC plants focused on combustion and post-combustion technologies for SO2, NOx and PM; New effort on Aspen-based modeling of IGCC systems (DOE/METC)

• Parallel EPRI support for extensive modeling of multimedia hazardous air pollutants emissions (PISCES model); Mercury control technologies added to IECM in late 1990s

• First distribution of IECM on CDs at selected conferences


Period IIIPeriod III

• Rapid growth in use of the Internet for disseminating tools and information; IECM now available via downloading

• Under the DOE/NETL Carbon Sequestration Program, a major expansion of IECM to add IGCC and NGCC power plants, and to add CO2 capture, transport and storage options

• Major enhancements to IECM software to maintain speed and user-friendliness with this greatly increased scope

• Increasing demands for technical support for IECM users

• One recent email from an IECM user (May 2008):

Dr. Rubin, We have never met but I've had the opportunity to hear you speak at CCS-related meetings over the years. I work for ConocoPhillips as a chemist in a small hydrogen-carbon dioxide group at their research center in Bartlesville, OK where one of our responsibilities is to help prepare downstream/refinery operations for carbon dioxide capture/mitigation.

We've recently started using your IECM website to guide us in developing preliminary cost estimates for our operations. Refinery carbon capture has its own issues, but the information on the IECM website is extremely helpful. I just wanted to send along a note of thanks to you and Carnegie-Mellon for making this model available and the technical support behind it. We appreciate your work very much.

Sincerely, George SchuetteHydrogen - Carbon Dioxide Group ConocoPhillips Technology Center


Value of IECM for EducationValue of IECM for Education

Dear Professor Rubin,I'm an assistant professor (chemical engineer) in the Energy Resources Engineering Department at Stanford University. This fall I'll be co-teaching a course w/ Sally Benson (another faculty member in our dept) on carbon capture and sequestration. We're really eager to use your IECM software package throughout our course this fall. Have you developed any homework problems or examples to go along w/ the software? If you have, are they available?I'll be co-chairing several sessions at the Pittsburgh Coal Conference in Sept/Oct and I'm hoping to use examples from both industry and research (from colleagues in the field) to incorporate into the HW problems for the course. Also, we'll be presenting material/learning outcomes in a session titled, Truly Interdisciplinary Courses, at the annual AIChE conference in Philadelphia in November. It would be wonderful to get together in person sometime to share ideas and to share with you our experience for using your program directly in our new course.Any advice you might have would be greatly appreciated.Thank you and take care,Jen WilcoxStanford UniversityDepartment of Energy Resources Engineering
