With increased demands to reduce SO2 emissions and lower energy consumption, Clark Solutions highlights the advantages of single absorption sulphuric acid plants compared to double absorption plants.
This case study reports on the successful collaboration of two experienced partner companies to replace the problematic upper part of a co-current flow quench tower in a spent acid plant and shows the benefits of using resistant, pre-lined workshop fabricated equipment.
TOYO explores green methanol synthesis technology and the challenges in utilising renewable energy sources and introduces its g-Methanol® technology.
Navigance, delves into the world of artificial intelligence (AI) and discusses its potential to enhance process optimisation in syngas plants.
Kevin De Bois of Prayon Technologies describes an innovative process for removing magnesium from phosphate rock. Increasingly, phosphoric acid producers are looking to consume low-grade phosphate rock as a feedstock due to the prohibitive costs of high-grade rock sources. This has potentially negative consequences as the presence of impurities such as magnesium can negatively affect both the phosphoric acid process and the quality of the acid produced.
With the addition of Green Granulation technology (GGT), Casale is the only industry licensor able to provide customers with an entire nitrogen fertilizer complex. Ken Monstrey and Matteo Fumagalli of Casale outline the benefits of this technology and its revolutionary new elements.
Steinmüller Engineering shares its experiences of applying CFD to re-design the waste heat boiler downstream of the secondary reformer to successfully achieve the desired uniform cross flow across the tube bundle.
Honeywell UOP’s nViro Hydro process provides an alternative solution to conventional hydroprocessing waste treatment. Benefits include creating a new revenue stream and reduced capital outlays, operating expenses and water use.
PT Petrokimia Gresik detail an inventive redesign of their economiser, a critical component in sulphuric acid production, focusing on energy efficiency, decarbonisation, process optimisation, and equipment durability.
A new burner design for the combustion of natural gas with either combustion air or pure oxygen as the oxidiser has been developed by CS Combustion Solutions. The new Oxijet®-Burner has been designed to perform both start-up and main operation functions with one burner.
