Hello, my name is Hans Esselink, graduate from Delft Technical University
and keeping office just outside the village of Odijk, near Utrecht, The Netherlands,
as managing director of ESSELINK B.V., formerly named Ingenieursbureau ESSEX B.V.
During most of my professional life, I have been active in the chemical
engineering profession; during the last 25 years as an independent consultant.
As my name and above logo already suggests, I act as a "LINK" between
the industry and my "WORKING TOOLS", integrated under the sigma symbol.
Through the years, specialization has been focussed on hydrogen purification through
Pressure Swing Adsorption.
