Chemical process development of Sorel cement from seawater bitterns using

TRIZ methodology   by

Charles W. Lipp, Lake Innovation LLC, Lake Jackson, Tx USA

Musad Ranna, MCC Bangladesh, Bogra, Bangledesh, India

 Abstract:

The primary goal of the project was to develop a replacement with a lower carbon dioxide footprint than Portland cement for use in building construction in Bangledesh. The MCC process concentrates and purifies the bitterns to produce a magnesium chloride solution that is dehydrochlorinated to produce magnesium oxide.  The TRIZ toolbox proved invaluable in accelerating the development of a magnesium oxide process.  Analysis of the proven spray reactor technology identified complications.  After the initial chemical reactor concept was radically changed, it was demonstrated with pilot plant testing.  Analysis shows this process has a significantly smaller carbon dioxide footprint than Portland cement. Functional analysis proved to be a critical tool along with others in TRIZ tools.

 

 



Charles W. Lipp is a Principle Consultant at Lake Innovation, LLC. He was a Technical Leader in the Engineering and Process Development department of The Dow Chemical Company.  During his career at Dow Chemical, he developed technology for process mixing, atomization, and coal gasification.  His expertise areas include process scale-up, static mixing, agitated tank mixing, tank jet mixing, two phase flow, Excel VBA based engineering design tools, and systematic problem solving (TRIZ).  This has resulted in numerous patents and technical presentations.  He authored the Sprays article for Kirk-Othmer Encyclopedia of Chemical Technology 5th ed, a Chemical Engineering Magazine article in 2008 and taught the Atomization and Spray Technology short course for the University of Wisconsin Center for Professional Development.  He serves as a Board of Directors member for ILASS Americas (Institute for Liquid Atomization and Spray Systems) and a member of AIChE.

A tool to estimate the strength and life of a Patent

TRIZ (Theory of Inventive Problem Solving) classifies inventions into five novelty levels. At level 1 are slight modifications of the existing systems.  At level 2 are those inventions that resolve a system conflict or contradiction using usually inventive solution or inventive principle used to solve similar problems in other systems.    At level 3, the inventions change one subsystem or resolve the system conflicts in a fundamental way. At level 4, the invention gives birth to new systems using interdisciplinary approaches. The level 5 inventions are closer to a recently discovered scientific phenomenon. See article for a complete discussion.

Alexander Selyutsky - a key figure in the history of TRIZ!

Alexander Selyutsky

Selyutsky Alexander Borisovich was born April 6, 1933 to an intelligent Jewish family residing in Leningrad. During the World War II the plant where his father was working was evacuated to the Urals, and the family (the parents and Alexander) moved to Chelyabinsk. Here, Alexander graduated from high school. He wanted to go to a military school, but didn’t pass vision test and entered the Chelyabinsk Polytechnic Institute. In his first year he was forced to learn boxing (because of frequent anti-Semitic attacks) and became a Komsomol activist.

After graduation, he was sent to Petrozavodsk Onega tractor plant, where he worked as a designer. He continued leading a very active social life, organized and led voluntary militia patrolling the streets of the city because the situation was very criminal. In the search for more satisfying work he became interested in patenting, completed appropriate courses and became a patent agent.

In 1960, Alexander married Dolly Naumovna Audleys, and had a daughter Alla in 1961. The same year G.S Altshuller published a book " “Learn how to invent"[1] . After reading this book in 1965 Selyutsky wrote a letter to Altshuller. This letter started their acquaintance by correspondence. Since then, Alexander became one of the most dedicated Altshuller’s disciples and an active promoter of the emerging new science.

They finally met in 1968 in Dzintary (near Riga), at the seminar organized by the Central Board of VOIR (state leading inventors’ and innovators’ society) that invited Altshuller and several of his associates. It was the first time that Alexander and others got a chance to work under the direct guidance of Altshuller and to learn from him. Later, in 1983, Alexander participated as one of the instructors in the seminar conducted by G.S. Altshuller in Moscow at the Institute for continuous education for chemical and petroleum industries.
