Chemical process development of Sorel cement from seawater bitterns using

TRIZ methodology   by

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

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.

Case Studies From A Breakthrough Innovation
"Starting in August 2004, the Hong Kong government began sponsoring a deployment of TRIZ to a cluster of eight local companies. Over the course of the next 15 months, each company was invited to assemble a team of between 5 and 8 engineers and designers each of whom would be exposed to a series of six three-day TRIZ education and utilization sessions. The aims of the program were for each company to realize new products, patents and tangible financial benefits, and to measure the extent to which TRIZ allowed companies to accelerate their rate of innovation. This paper describes a collection of some of the success stories emerging from the program."

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.
