Sulphur reports on this year’s Sour Oil and Gas Advanced Technology (SOGAT) conference, which was run as a virtual event at the end of September 2020.

thyssenkrupp Industrial Solutions discusses a revamping concept to reduce CO2 emissions by replacing some of the hydrogen in the front end of the ammonia plant with green hydrogen, KBR and Casale report on revamp options to increase the capacity of vintage ammonia plants in the former Soviet Union, Johnson Matthey presents a novel integrated ammonia flowsheet for the production of ammonia, methanol, urea and UFC and Arvos | Schmidtsche Schack discusses the benefits of a new process gas boiler.

K. Hanlon Kinsberg and J. Lewis of Comprimo review the main approaches for mercaptan removal in gas processing plants, based on past project experience and generally accepted industry practice.

An advanced mecaptan removal process has been developed and implemented by RATE. The RATE-Oximer process is an oxidative air-based regeneration process, designed to remove mercaptans from liquid and vapour phases. M. Rameshini of RATE describes the key features of the process and its applications.

N. Temnaya and S. Suvorkin of NIIK report on the modernisation of monopressure (UKL-7) and dual pressure (AK-72) nitric acid plants in Russia and the CIS.

New technology makes it possible for methanol producers to diversify their product portfolio and participate in the high growth mono ethylene glycol market. A. Shah of Johnson Matthey reports on the development of the new technology and its commercialisation.

Process gas boilers with an internal bypass system are an important type of shell-and-tube heat exchanger installed in steam methane reforming units. For decades, two traditional designs have dominated the market: the “hot” and “cold” bypass process gas boiler. Today, a third option based on a new design concept is available: the “bayonet” bypass process gas boiler, with process and mechanical features that can provide superior performance, lower opex and improved reliability. G. Manenti of Alfa Laval Olmi SpA discusses the design and operating principles of the different designs.

Evaporation and crystallisation are widely used throughout the fertilizer industry. Major applications and the types of equipment used are reviewed by Laurent Palierne and Norbert Strieder of GEA Group.

Digitalisation and the analysis of big data are playing an increasing role in fertilizer production. Innovative digital and cloud-based services are being offered by a range of technology companies, including Casale, tkIS, Topsoe and TOYO.

Three large-scale phosphoric acid plants constructed as part of the world-class Umm Wu’al project in Saudi Arabia are now fully operational. James Byrd of Worley (formerly Jacobs ECR) describes the execution of the project from basic engineering through to plant performance tests.
