I’ve worked with energy and environmental issues since I graduated as a M.Sc. in mech. eng. from DTU in 1989 with a thesis on Pinch Technology. After a few years work as consulting engineer exploiting my knowledge on process integration I decided to go for an industrial Ph.D. in Chem. Eng. – with a thesis about process integration and mathematical modeling.I have spent 3 years with the fertilizer manufacturer Kemira working on energy optimization and 10 years with dk-TEKNIK working on a variety of projects – all related to industrial energy optimization or environmental impact minimization.In 2003 I decided together with a longtime colleague Mogens Weel to form our own company. Our main goal was to provide solutions to the industry based on fundamental insight in the industrial processes using a system approach and modeling techniques. We are now having a series of software products including• WS.PEMS Predictive emission and monitoring system• WS.WTE Simulation package for full scale simulation of waste incineration plants• WS.SteamTurb Simulation package for detailed steam turbine simulation• WS.PINCH Pinch based energy optimsation tool• HEN-Explorer Advanced heat exchanger network optimization based on my Ph.D workDuring the last five years I’ve been travelling extensively especially in the Middle East to promote our WS.PEMS system. It has been a very interesting and successful experience. We have now running monitoring systems in UAE and Oman and are currently executing projects in Qatar and Saudi Arabia. I’ve learned that patience and persistency are key features if you want success.Since 2005 I’ve been involved in international cooperation under the International Energy Agency. As a representative for Denmark I was co-founding the Technology Agreement IEA-IETS which deals with international cooperation on industrial energy technologies. In 2007 I was appointed vice chair and 2009 chair of the IEA-IETS Executive Committee.
