Wastewater treatment in a urea plant

A detailed rain and wastewater concept is an important part of a urea plant to meet current stringent environmental standards. Wastewater can originate from the process reaction or from outside the process equipment. In order to optimise the wastewater system of a urea plant, both the amount and type of contamination need to be known. With this knowledge, non-contaminated rainwater as well as process drains can be kept separate as much as possible to minimise the amount of wastewater to be treated, saving costs and energy. Wastewater treatment concepts from thyssenkrupp Industrial Solutions and Toyo Engineering Corporation are described.

On the lookout for gas leaks

Scanfeld™ is the world’s first remote sensing solution for fully automated early-warning gas leak detection for chemical plants. Using FTIR spectroscopy, Scanfeld™ identifies hundreds of different gases in real time from kilometres away. With just a few Scanfeld™ sensor units, large production sites, tank farms, or gas loading areas can be monitored reliably. Gas leaks are quickly detected, and the formation of dangerous gas clouds is monitored, measured, and visualised. René Braun of Grandperspective discusses how the system works and how it is being applied in industry.

The shape of things to come?

Global nitrogen and methanol markets are currently in the grip of a crisis in feedstock prices. Mostly this is about Europe’s dependence on imported natural gas, but – particularly on the methanol side – it has also been exacerbated by high coal prices in China, where heavy rains have led to flooding in Shanxi province, the source of one third of China’s coal. These have followed similar floods in Henan in July, and come at a time when China is facing power rationing due to a lack of electricity supply. The world economy’s long-awaited bounce back from the covid pandemic has also led to a general global surge in energy demand, and consequently higher oil and gas prices.
