Saipem, Stamicarbon, Toyo Engineering Corporation and KBR showcase recent projects and latest technology for urea and nitric acid plants.

Stamicarbon offers advanced scrubbing technologies for fertilizer granulation plants and prilling towers. This article describes the technology and experience with the second operational MMV scrubber, which is installed at the Dakota Gasification Company’s (DGC) urea granulation plant, and highlights the successful pilot test with its JV scrubbing technology.

More than 230 delegates from 45 countries participated in CRU’s Sustainable Fertilizer Production Technology Forum, 20-23 September 2021. To highlight this successful virtual event, we report on keynote and selected technical presentations.

Nitrogen-rich wastewaters remain a major issue for fertilizer and other industries. Saipem’s new electrochemical technology, SPELL, is an important step towards the overall objective of zero industrial pollution. A complete engineering review of the technology, its alignment with all international applicable standards, and optimisation has now been concluded and the technology is ready for deployment for the removal of ammonium nitrogen from industrial waters and wastewaters. Saipem discusses the key features of SPELL and reports on the first two industrial references.

China’s private sector Shenghong Petrochemical refining complex is targeting a startup in late November, following the receipt of its first cargo of crude in October. The greenfield refining complex in the eastern Lianyungang petrochemical zone has a capacity of 16 million t/a, including a 320,000 bbl/d crude unit – the largest single stream CDU in China – and a 76,000 bbl/d naphtha reformer. Product capacities include 56,000 bbl/d of gasoline, 41,000 bbl/d of diesel and 32,000 bbl/d of jet fuel. Construction began in mid-2019, delayed from 2018 by late approval of its environmental impact assessment, but has been achieved within two months of the scheduled completion date in spite of the coronavirus pandemic. Shenghong Petrochemical is owned by Eastern Shenghong, a producer of petrochemical products and chemical fibres.

Chemetics describes a variety of ways to extend the life of sulphuric acid plants. Debottlenecking, emissions reduction and/or energy recovery projects require a systematic, phased approach to maximise the potential of economic and operational benefits to the owner.

A. Goudarzi of CECO Industrial Solutions discusses the science behind NOx content and how it impacts sulphuric acid producers. In a recent project in Korea, TWIN-PAK® candle filter technology was successfully used to reduce NOx emissions in metallurgical oleum tower production. After installation of the candle filter mist eliminators the plant was compliant with environmental regulations enabling the producer to operate the plant without penalties or shutdowns.

We highlight recent advances in ammonia and dust scrubbing systems for urea plants from Stamicarbon, thyssenkrupp Industrial Solutions and Toyo Engineering Corporation.

This year’s SulGas conference, covering sulphur recovery and gas treating with a special focus on India and southeast Asia, was run as a virtual event from February 1st to 3rd 2021.

The quality of finished fertilizers can be maintained during transport, handling and storage by protecting the surfaces of granules and prills with coating agents. We survey the range of anti-caking, water repellent and anti-dusting additives currently on the market.
