In 2017 my launching customer as independent consultant was a large oil terminal in the port of Rotterdam. This terminal needed to reduce their environmental footprint. The fuel oil odour emission needed to be reduced fast. I supported the customer in the process design, HAZOP and facilitated maintenance and start-up support for the relocation of two existing RTO’s. The RTO’s became obsolete at another plant (semiconductor industry). Since these systems were designed for clean solvent duty it was required to install upstream H₂S removal. The H₂S removal was also required to meet the SO₂ emission limit.
