How to increase Ammonia Plant Capacity

This paper investigates the technical and economical feasibility of several concepts for a 30 % capacity increase of an old ammonia plant. It shows an interesting way to overcome the limitations in the two most critical plant units: Reforming capacity is increased by a newly added autothermal reformer, while capacity is added to the ammonia synthesis by the Uhde Dual Pressure Process.

Smart Actuation for a Smarter World

Today’s modern water and wastewater treatment plants are employing advanced technologies, reverse osmosis for instance, to provide clean potable water across India. These technologies call for accurate information and precise flow control throughout the plant, which is difficult to achieve by manual operation. This has resulted in the increased use of electric actuators to operate valves installed throughout the plant, right from intake stage to the pumping station for distribution.

Against the Tide: What Has Lanxess Planned with its State-of-the-Art Production in Belgium?

A German chemicals group planning a major investment in Central Europe is certainly something out of the ordinary. But a company that spends several hundred million Euros in ramping up capacities in a seemingly saturated market must have something in mind. Just like the polymer specialists Lanxess, who, since 2004, have invested over 300 million euros in its Belgian flagship site in Antwerp. What is the story behind these? On the 50-year anniversary of caprolactam production on the banks of the river Scheldt, the Cologne-based company lets us have a look behind the scenes…
