Each of the systems that we have designed and built under this category of projects can be described by reference to one of the following polymerization processes:
Bulk or block polymerization
This process is the simplest in terms of formulation, and is conducted in the absence of any solvent or dispersant. A monomer, polymer and initiator are the only components. Applications include most step-growth and many chain-growth polymers.
Decaffeination is the process of removing caffeine from materials such as coffee beans, tea leaves, kola nuts and cocoa beans. Over the years, dozens of decaffeination methods have been developed and tested, and some have been commercialized with varying degrees of success. Most of these methods fall into one of the following three categories:
DME Clean Energy Pty. Ltd. (DMECE) intends to develop a new opportunity for the struggling Australian brown coal industry. The company has asked Unitel to design an enhanced process for making DME from brown coal mined in the State of Victoria. With a prevailing price of $7 per ton for brown coal, the underlying economics of this business are exceptionally attractive.
In May of 2010, Unitel delivered the first of its latest computer-controlled catalyst testing and evaluation systems – CTS Version 8, the Octave – to the University of Louisville’s Conn Center for Renewable Research and Environmental Stewardship (CCRRES). According to Dr. Paul Ratnasamy, Professor at CCRRES, initial experiments with the Octave will focus on catalytic conversion of waste oils into fuels. Following that, Paul intends to test custom catalysts for making fuel alcohols from synthesis gas.
