Wet process phosphoric acid plants require reliable cooling water facilities. Jan Tytgat, engineering manager, De Smet Agro, shares his insights on the design and operation of cooling water networks, pumps and towers.
By using modular construction, operational modelling and digital plant control, thyssenkrupp Uhde can offer customers fast-build, capital efficient green ammonia plants. Dr Christian Renk and Dr Klaus Nölker explain the company’s innovative approach to plant construction, design and control.
The Woodsmith polyhalite project in the UK is starting to benefit from Anglo American’s ownership, with the mining major leveraging its key advantages to good effect. These include the company’s operational size and financial stability, its vast mineral extraction experience, and premium product marketing expertise. The company also believes that the fertilizer sector will benefit from its leadership in mining industry sustainability.
Gidara Energy has agreed with the Port of Rotterdam to develop a new waste to methanol facility in the Netherlands: Advanced Methanol Rotterdam (AMR). Gidara will duplicate its Advanced Methanol Amsterdam project as a template for AMR, using Gidara’s patented high temperature Winkler (HTW® ) technology, which converts nonrecyclable waste to renewable fuels. This technology has been used commercially in four other waste to syngas production facilities. AMR will convert around 180,000 t/a of non-recyclable waste into 90,000 t/a of methanol, while capturing all waste streams for use; CO2 will be captured and led to local greenhouses; bottom product residue will be used for cement production; and other streams like ammonia and salts will be sold and put to use as feed stock for other industries and road salt respectively, creating a fully circular concept. The facility is scheduled to start detail engineering and construction in the first half of 2023, when a permit is received, and start production of renewable methanol in 2025.
India’s new batch of urea plants are coming on-stream or nearing completion, but can the country regain the self-sufficiency in urea production that it enjoyed in the 1990s?
Erika Niino-Esser of thyssenkrupp Industrial Solutions explains the importance of thyssenkrupp’s technologies for sustainable hydrogen and ammonia value chains in the global energy transition, and how they are contributing to a climate-neutral world. Several novel green hydrogen projects are also highlighted.
Casale has acquired Hong Kong-based Green Granulation Ltd (GGL), and its proprietary technologies for the design and construction of urea and calcium ammonium nitrate (CAN) granulation systems. Casale says that the takeover is part of a broader strategy aimed at strengthening its leading position in the nitrogen market by leveraging the widest integrated portfolio of efficient technologies, enabling the company to offer a ‘one stop shop’ for the entire production cycle of nitrogen-based fertilizers, from raw materials to final products. GGL’s addition to the Casale group includes the Cold Recycle Granulation process, an advanced fluidised bed technology designed to accept a lower concentration of urea feed melt (ca 96% urea and biuret), as well as a proprietary design for both granulator and scrubber, a team of experts and qualified technicians, and considerable experience in several industrial references. The CRG design has a horizontal layout, leading to lower structural costs and higher efficiency, as well as lower total investment costs and power consumption, lower power consumption and simplified operation, and higher operational flexibility in urea and CAN granulation.
For some years the fastest growing sector of the methanol market was Chinese olefins production. However, with growth there flattening out, it is traditional chemical uses which are taking over again as drivers of demand growth, with, longer term, a major prospect from fuel and energy applications.
EuroChem Group recently completed the purchase of the Serra do Salitre project from Yara International for $452 million. This one million tonne capacity Brazilian phosphate project is due to be completed in 2024.
