Revamping aging urea plants with the latest urea technology brings many benefits. Not only can greenhouse gas emissions be reduced, but the overall performance and sustainability of these facilities can also be optimised. Hiroo Kunii of Toyo Engineering Corporation discusses TOYO’s approach to urea plant revamping.
In this revamp case study Scott Kafesjian and Quinn Kotter of Wood demonstrate how Wood sulphur technology was implemented at a 46-year old refinery SRU to improve reliability, operability and performance to meet new requirements for increased flexibility and higher availability.
Urea revamp activities are performed to achieve improvements of the urea plant. Besides the typical capacity increase there are many options to reduce operation costs, increase plant availability or reduce environmental impact. In this article Marc Wieschalla of thyssenkrupp Uhde GmbH provides an overview of some of the options from an EPC contractor point of view.
In this case study, Florian Kistl of CS Combustion Solutions presents a comprehensive strategy for the capacity enhancement and optimisation of a sulphuric acid production plant that was facing several operational challenges that were hindering its efficiency and reliability. As a result of a series of targeted optimisations, including the innovative use of ultrasonic nozzles and CFD modelling, downtime and maintenance costs were reduced, and a substantial capacity increase was achieved.
Aparna Saiju and Nishevitha U G of SLB-MPS explore the concept of energy optimisation using power recovery turbine (PRT) technology in amine sweetening units, focusing on its potential benefits, implementation strategies, and environmental implications.
Large-scale ammonia cracking technology and catalysts will enable the full potential of ammonia to be realised as industries transition towards low carbon energy. In this feature we report on the current status of ammonia cracking processes and catalysts.
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.
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.
The ammonia industry is expected to change drastically in the coming years to meet sustainability goals and to face the problem of climate change. New low carbon ammonia plants as well as fully green facilities are expected to be commissioned to meet the target of climate neutral production. The integration of an existing ammonia facility with green hydrogen to supplement or replace the grey ammonia production with green ammonia represents a low-risk solution to meet the requirement for running clean ammonia plants and offers the most competitive green ammonia production cost in the short term. In this article Sergio Panza and Marco M. Carlucci of Casale paper present different scenarios based on energy availability at battery limits.
Sulphur production continues to expand in the Middle East and China both from new refineries and major sour gas projects.
