· About ·
Leon
I am a seasoned Process Engineer with over 25 years of experience in designing and optimizing processes and equipment while executing projects in the chemical industry and being part of R&D. My expertise spans a broad range of industries, with a particular focus on Urea, Nitric Acid, Ammonium Nitrate, and (re-)emerging technologies like Green Ammonia.
