Brazil: boom or bubble?

Summary

A transformed domestic economy and new discoveries of oil are changing the equation for Brazil's chemical industries, but in the medium term analysts are warning of a hard landing for the world's sixth largest economy.

Emissions trading and the fertilizer industry

Summary

From January 2013 the European fertilizer industry will fall under the European Union's Emissions Trading Scheme (ETS). Nitrogen+Syngas looks at what this will mean for ammonia producers in Europe and further afield.

Novel schemes to co-produce methanol and ammonia

Summary

The interest in plants for the co-production of methanol and ammonia has been growing as plant owners look for greater flexibility in product mix to respond to market demands and to benefit during times of product price fluctuations. Technology providers have been developing new co-production schemes to provide more cost effective process configurations, maximise production, reduce energy consumption and provide greater product flexibility. The latest approaches and developments to integrate methanol and ammonia production are presented from Haldor Topsøe, Toyo Engineering Corporation and Methanol Casale.

A new low methanol LTS catalyst

Summary

In an increasingly competitive market, catalyst selection is of significant importance when it comes to optimising performance in ammonia plants. Installing high performance catalysts improves overall plant efficiency and ensures optimal feedstock utilisation, thereby increasing profit margin. Ground-breaking research on catalysts for ammonia production has resulted in a new low methanol LTS catalyst from Topsøe, LK-853 FENCE™. K. Svennerberg of Haldor Topsøe highlights the developmental work, the unique catalyst features and discusses how ammonia producers can benefit from these latest developments.

Methanol plants keep getting bigger

Summary

World demand for methanol has been growing steadily over the last years, a trend that is expected to continue. Cost-efficient methanol production is the key for methanol producers to improve profit margin in an increasingly competitive market. This has spurred the development of new technology and catalysts for much larger methanol plants approaching capacities of 10,000 t/d, or more. The drivers behind this expansion are economy of scale but also the emergence of new large scale applications of methanol such as MTO and methanol used for gasoline blend stock. In large-scale single-line production units, previously known limits for both equipment and catalysts are being challenged. This article highlights the latest technologies for large-scale methanol production offered by Air Liquide, Topsøe, Toyo and Casale.

Plant Manager+ Problem No. 11 How to run high pressure centrifugal pumps in parallel mode

Summary

When operators have a bad experience when operating critical equipment in certain modes, how do you convince them that operating in a certain mode should be possible and that it will bring benefits? This round table discussion discusses the parallel operation of high pressure centrifugal carbamate pumps. High pressure centrifugal carbamate pumps are critical equipment items and several process requirements need to be fulfilled to avoid problems and damage. Sharing experiences can improve the knowledge of how to operate these critical equipment items and help operators to overcome their bad experiences.
