SULPHURIC ACID PLANTS
Sulphur’s annual survey of recent and planned construction projects in the sulphuric acid industry includes several large-scale acid plants both for phosphate processing and to capture sulphur dioxide from smelters.
In Part 4 of this series on stripper efficiency issues, we continue to look at the causes of lower stripper efficiency with a discussion on the high delta-P range of liquid dividers.
This study introduces a new platinum-promoted honeycomb catalyst for sulphur dioxide oxidation, designed to enhance energy efficiency and reduce emissions in sulphuric acid production. Compared to conventional vanadium oxide based catalysts, the platinum-based catalyst demonstrates higher catalytic activity, lower ignition temperature, and significantly reduced toxicity.
While there is still a considerable push for use of biomass waste as a lower carbon feedstock for chemical production via gasification to syngas, biological processes such as fermentation are increasingly gaining traction as an alternative.
Syngas generation units (SGU) represent a large portion of the capital and operational expenditure of ammonia plants and are critical from a mechanical reliability standpoint. Related capex/opex optimisation and mitigation of possible operational problems are key targets for ammonia plant owners. Giovanni Manenti introduces NITROQUENCH® technology which focuses on these key targets for ammonia SGU.
The 38th Nitrogen+Syngas Expoconference will take place in Barcelona, Spain, from 10-12 February 2025. Join us at this industry leading event featuring the most comprehensive agenda to date.
