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.
For six decades, Chemetics has been a pioneering force in the sulphuric acid design and equipment industry, consistently introducing groundbreaking technologies that have revolutionised the field by optimising the methodology in which chemicals are produced. This year, Chemetics celebrates its 60-year anniversary as one of the leading designers, direct equipment suppliers and fabricators that has modernised the sulphuric acid industry of today. This article dives into Chemetics’ rich history and key innovations that have shaped and moulded the industry.
Transporting sulphur as a dry bulk solid can lead to it breaking into small particles which create dust. Over the years, various forming processes have been developed to try and minimise dust formation and produce the strongest, most resilient formed sulphur particles.
We highlight recent production advances and innovations in nitrogen fertilizer production from Casale and Stamicarbon, two global leaders in process technology.
Sulphur Experts outline the steps required to determine optimised SRU incinerator operating conditions. Although a proper determination of the ideal SRU incinerator operating conditions for any given facility is complicated by a combination of inconsistent permitting standards and poor understanding of the role of the SRU incinerator, the payoff for incinerator optimisation is a significant decrease in natural gas usage with corresponding savings in operating costs, a decrease in CO2 emissions, and a simultaneous reduction in NOx and SO3 emissions.
Waste heat recovery in the potash industry is now possible thanks to the availability or robust and reliable heat pipe heat exchangers (HPHEs). Igor Makarenko , Solex Thermal Science, explains how HPHE technology can help potash producers reduce their primary energy consumption and cut their CO 2 emissions.
A sulphuric acid plant in Northwest China is looking to capture its low-grade heat for re-use. With the support of Alfa Laval’s semi-welded plate heat exchangers and energy recovery expertise, in winter, all of the recovered low-grade heat could be put back into their system with 30% being used in production and the remaining 70% going to heating. During the summer, 14% of the energy that is no longer needed for indoor heating could be used to preheat boiler feedwater. This would enable them to significantly reduce the amount of fossil fuels used in production, without redesigning their entire factory footprint.
A report on CRU’s annual Sulphur + Sulphuric Acid conference, held in New Orleans, USA, 6-8 November 2023.
Anggi Arifin Nasution and Aldifi Putro of 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.
Ballestra, Nitricity, Solex Thermal Science and Stamicarbon showcase their state-ofthe-art equipment and technologies.
