ASRL has conducted studies on ammonia destruction in the sulphur recovery unit (SRU) for over a decade1-5 . Other studies at ASRL have investigated mechanisms for ammonium salt formation and deposition downstream in the Claus plant, as well as the potential sources of ammonia (NH3 )in a gas plant7 . A less understood subject is addressing how much residual NH3 is tolerable or at what temperature will residual NH3 cause ammonium salt deposition. In this study, existing knowledge on thermal stability of ammonium salts and new measurements have been used to identify the gaseous components required for deposition, through reversible vapour pressure expressions.

INEOS Enterprises has announced the completion of the sale of its Sulphur Chemicals business to International Chemical Investors Group, for an undisclosed sum. INEOS Sulphur Chemicals business is Spain’s largest dedicated manufacturer of sulphuric acid and oleum, serving clients in both agriculture and chemical intermediates via its 400,000 t/a plant in Bilbao. The business will become part of WeylChem’s advanced intermediates and reagents portfolio, which includes an existing sulphuric acid and oleum plant located in Lamotte, northern France. WeylChem is wholly owned by the International Chemical Investors Group (ICIG).

Comprimo has recently launched two new solutions to make the most of existing data and to improve customer’s operations and customer knowhow: Comprimo Insight – an intelligent sulphur plant dashboard, and Comprimo Immerse – a dynamic sulphur plant simulator. In this article, Comprimo goes into the details of how Comprimo Insight and Comprimo Immerse are being implemented for its customers.

Ammonia and sulphur, as essential raw materials, underpin and drive fertilizer production costs. A steep and sustained rally has seen prices for both commodities reach new heights in recent months.

The delivery of nitrogen in nitrate form can deliver superior yields and quality in arable, fruit and vegetable crops. Because of this, production and consumption of the principal nitrate fertilizers – ammonium nitrate (AN), calcium ammonium nitrate (CAN), urea ammonium nitrate (UAN), potassium nitrate (NOP) and calcium nitrate (CN) – continue to grow.

Preliminary engineering work has started on a renewable powerto-fertilizer plant in Kenya.

In 2019, the EU fertilizer market was valued at around e17 billion, with France, Germany and former member state the UK together representing 40 percent of this total.

Ammonia markets continue to be dominated by unplanned outages in Saudi Arabia (where the SAFCO 4 and one of the Ma’aden ammonia plants are both down, removing 2.3 million t/a of merchant ammonia from the market). This comes on top of other shutdowns earlier in the year on Trinidad, in the US and Australia.
