The following case studies describe serious incidents associated with leak detection system failures. Incident 4 relates to the failure of the active pressurised leak detection system for the loose liner of a urea reactor and Incident 5 relates to a passive leak detection system which failed to work leading to serious corrosion of the carbon steel wall of the HP scrubber.
Building on its long experience and leading position within global ammonia production, logistics and trade, Yara says that it aims to capture opportunities in green shipping, agriculture and industrial applications; a market expected to grow by 60% over the next two decades. A major first step includes plans to fully electrify its ammonia plant at Porsgrunn, Norway, with the potential to cut 800,000 t/a of CO 2 , equivalent to the emissions from 300,000 passenger cars.

Ammonia supplies have been curtailed by production shutdowns, including Kaltim and PT PAU in Indonesia, SABIC and Ma’aden in Saudi Arabia, Sorfert in Algeria and Chinese gas-based producers. There have also been gas curtailments in Iran and Trinidad.

As urea plants grow in capacity, so does the need for finishing technologies with higher capacities. Barbara Cucchiella , senior process engineer at Stamicarbon, describes how her team has risen to the challenge of the global trend for larger granulation plants.
Recent innovations in fertilizer granulation include thyssenkrupp’s new process for premium ammonium sulphate production. Eirich has launched new equipment for NPK granulation, while Rhewum is also offering new screening technology.
Latin America has confirmed its status as a pre-eminent global marketplace for fertilizers. We report on demand growth and fertilizer supply and capacity developments within this diverse region.

This case study describes a backflow scenario in a pressurised leak detection system. Backflow can occur in case of a relatively large leak (crack in liner), where the flowmeter installed downstream of the equipment acts as a flow restriction, allowing pressure to build up.
