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.

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.

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.

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.

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.

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.

The falling film high pressure carbamate condenser (HPCC) was the first type of high pressure carbamate condenser applied in urea stripping plants. Did you know that the first Snamprogetti stripping plants also had falling film carbamate condensers? In 1978 Mr Umberto Zardi, later founder of Casale, invented the horizontal kettle type condenser for Snamprogetti urea plants.

We look at safety, health and environmental (SHE) management and hazards at nitrogen fertilizer plants and the importance of the International Fertilizer Association’s ‘Protect & Sustain’ certification scheme.
