Chile’s environmental regulator SMA has filed a charge against state-owned Codelco, alleging emission violations at its Potrerillos copper smelter in the Atacama region of northern Chile. An audit showed the company had not implemented a monitoring system for sulphur dioxide emissions and other procedures in accordance with environmental standards for the plant, Reuters news agency reported. The SMA labelled the charge as serious, which could lead to a fine of around $4.1 million, and possible revocation of the environmental permit or closure. Codelco had ten days to submit a compliance plan, and 15 days to present a defence.

Although China remains the world’s largest phosphate producer, it has been overtaken as the largest exporter by Morocco in recent years as domestic producers face continuing restrictions on exports.

Short term supply constraints are dominating acid markets at present, but increasing smelter production across Asia may lead to oversupply in the longer term.

Veolia says that its subsidiary Veolia North America has signed an agreement for the divestment of Veolia North America Regeneration Services, which includes its sulphuric acid and hydrofluoric acid regeneration activities for refineries, to private equity firm American Industrial Partners for $620 million. These activities represented revenues of around $350 million in 2023. The financial closure of the transaction is expected soon. Veolia’s Sulphuric Acid Regeneration Business includes its sulphuric acid and potassium hydroxide regeneration, as well as sulphur gas recovery, and sulphur-based products production businesses.

In this case study, Florian Kistl of CS Combustion Solutions presents a comprehensive strategy for the capacity enhancement and optimisation of a sulphuric acid production plant that was facing several operational challenges that were hindering its efficiency and reliability. As a result of a series of targeted optimisations, including the innovative use of ultrasonic nozzles and CFD modelling, downtime and maintenance costs were reduced, and a substantial capacity increase was achieved.

The newly-patented SWIFT process is designed to sequester fluorine at phosphoric acid plants in an environmentally responsible way. It can also offset the costs of fluorine management by generating a saleable dicalcium phosphate (DCP) end-product as an additional revenue stream. A number of capex and opex advantages provide the SWIFT process with highly favourable economics, as James Byrd of JESA Technologies explains.

More than 370 delegates from over 150 companies and 40 countries gathered at the Hilton Warsaw City Hotel, Warsaw, Poland, 26-28 February, for CRU’s Phosphates 2024 conference.

How does an engineering company complete the basic and detailed engineering for a phosphoric acid plant – and provide the full design for the off-site sections and utilities? Jan Tytgat, De Smet Agro’s Process Engineering Manager, explains an approach based on partnership with the technology licensor and client that combines engineering expertise with experience.

KBR designs and builds customised phosphoric acid purification plants tailored to the individual demands of clients. Christopher Heikkilä, KBR’s Business Development Manager, outlines the process design requirements and the challenges associated with impurities removal.
