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.
When SINOPEC made a decision to acquire 17 state-of-the-art pilot plants for its Research Institute of Petroleum Processing (RIPP) laboratories in Beijing and Fushun, it engaged Fluor Corporation to identify the “best” source for this equipment and manage all aspects of this procurement. Fluor in turn awarded the entire contract to our company under the leadership of Serge and Ravi Randhava.
The customer intends to develop an alternative and sustainable option to meet the nitrogen fertilizer requirements of the US agricultural industry. Currently our country consumes appr. 20 million tons of ammonia per year, and more than 50% of this product is imported from Trinidad, Russia and Canada.
The term polycarbonate refers to polymers with functional groups linked together by carbonate groups in a long molecular chain. Compared to most other plastics, polycarbonates offer incredible strength, exceptional durability, excellent transparency and light weight – one-sixth as heavy as glass – properties that position these materials between commodity and engineered plastics.
In response to environmental pressures, most countries in the world continue to decrease the allowed sulfur levels in diesel used for transportation applications. Currently (2010) all highway diesel fuel refined in or imported into the United States must have a sulfur content of 15 parts per million (ppm) or lower. Some countries in Europe are actively promoting the use of 10 ppm or even 5 ppm standards.
The US Army Fuel Cell Technology team at Fort Belvoir needed an integrated system to fine-tune its process for converting a logistical fuel into hydrogen for operating a solid oxide fuel-cell stack. The end objective was to generate “quiet power” – with a minimal thermal and sound signature – on the battlefield. Mobile applications also included auxiliary power units (APUs) on trucks and other military vehicles.
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.
