India’s phosphate production is using increasing volumes of sulphuric acid, but new domestic smelter and sulphur burning acid capacity may mean reduced imports in future.
NextChem has been awarded two contracts to upgrade and expand the capacity of the Heydar Aliyev Oil Refinery (HAOR) industrial complex in Baku by state oil company SOCAR. As part of the contract, NextChem will conduct a technological assessment and deliver a process design package to upgrade the existing sulphur recovery unit (SRU) with oxygen enriched air, a cost-effective and flexible solution for expanding its current sulphur production capacity. Additionally, NextChem will provide the licensing and the process design package based on its proprietary NX SulphuRec TM technology for a new SRU. NX SulphuRec TM is a portfolio of proprietary sulphur recovery technologies, based on the integration of modified Claus and tail gas treatment processes, aimed at reducing the environmental impact of acid and sour gases produced during the refining process.
The development and implementation of modern process instruments and control systems in sulphur recovery units has increased significantly over the last decade. In this article, the impact of BTEX on sulphur plant operations and how the BTEX concentrations can be measured are discussed.
Marcus Weber of Fluor discusses degassing units for large scale sulphur recovery units, evaluating the pros and cons of various available commercial technologies with the emphasis on mega size sulphur recovery units and focussing on how technology can lower degassing capex via economy of scale for new facilities or existing facilities undergoing expansion.
CRU’s 38th Nitrogen+Syngas Expoconference will be held on 10-12 February 2025 in Barcelona. The most respected technical event for the global nitrogen and syngas community offers an ideal platform for industry professionals to connect, do business and learn about the latest innovations in operations, technology, process and equipment. The annual meeting attracts a global audience of producers, licensors and materials and equipment providers representing an unparalleled opportunity for business networking and peer-to-peer knowledge sharing.
In Part 3 of this series on stripper efficiency issues, we continue the discussion on some some of the many causes of lower stripper efficiency. Here we discuss liquid divider fouling and bad installation of liquid dividers.
A report on CRU’s annual Sulphur+Sulphuric Acid Conference, held in Barcelona, in early November.
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.
One challenge of a green revamp by stepwise injection of green hydrogen into existing ammonia/urea complexes is to cover the nitrogen demand for the ammonia synthesis while stepwise reducing the front-end load, usually by applying a cost-intensive air separation unit (ASU). thyssenkrupp Uhde GmbH has developed an advantageous concept whereby, instead of an ASU, the nitrogen gap is closed by the introduction of pretreated reformer flue gas back into the ammonia process, with the side effect to also enhance CO2 production.
