Analysing COS and CS2 in a modern SRU
Maximising sulphur recovery in a modified Claus SRU/TGTU requires controlling and monitoring COS and CS2 . Leveraging decades of monitoring experience, AMETEK Process Instruments discusses the formation, impact and monitoring of COS and CS2 .
Nitricity raises $50M to go global
Nitricity has secured $50 million in funding and commenced building a liquid fertilizer production plant in Delhi, California.
Neutralisation of heat stable salts – Part 1
Joel Cantrell of Bryan Research & Engineering and Clay Jones of INEOS GAS/SPEC re-evaluate the historical practice of intentionally adding strong base such as caustic (NaOH) to amine with the purpose of improving performance and reducing corrosion by “neutralising” heat stable amine salts (HSAS) which have accumulated in the amine.
Platinum-catalysed conversion of sulphur species
Platinumpromoted honeycomb catalyst bricks offer lower pressure drop, higher activity, reduced toxicity, and function as total oxidation catalysts that convert all oxidisable species under appropriate temperature and oxygen conditions. A case is presented for a sulphur-resistant total oxidation catalyst processing a gas stream bearing high amounts of H2 S – relevant to the fibre industry, Claus offgas treatment, and other chemical sectors. Proper parameter settings enable conversion of H2 S to SO3 for concentrated sulphuric acid production. Additional applications for the total oxidation catalyst include metallurgical offgas treatment, VOC abatement, and CO abatement under harsh conditions.
Sulphur pit turnaround and rehabilitation
A full sulphur pit turnaround and rehabilitation is typically a once in a lifetime experience for refinery personnel. Specialists in sulphur pit turnarounds, Gavin Palmer of Brindley Engineering, Tom Kline and Bob Hall of Structural Technologies have compiled a database based on multiple sulphur pit turnarounds to identify typical deficiencies in mechanical systems, along with improvements to enhance operability, restore functionality and meet all codes/standards and best practices.
