• Plant Manager+ Problem No. 63 Holding reactor content during a long shutdown
  Every urea plant continuously fights again corrosion. The intermediate product ammonium carbamate is extremely corrosive under synthesis conditions. The applied materials of construction require oxygen to form a protective passive layer of chromium oxides. The ammonium carbamate solution will continuously dissolve the passive layer, therefore it is vital to continuously supply oxygen, typically in the form of air, to maintain the passive layer.

• Chinese ethylene capacity slows the MTO boom
  In China, requirements for methanol to produce olefins, mainly propylene and ethylene, from coal, has driven much of the growth in global methanol demand over the past decade. However, a new wave of ethylene cracker investment may put a stop to new MTO plant building.

• Barriers to trade
  With globalisation seemingly in retreat, the protectionist impulse is seeing a rise in barriers to trade, from quotas and tariffs to anti-dumping actions and domestic subsidies.

• Modular plant design
  A move towards smaller scale feedstocks such as renewable energy and waste and biomass gasification is leading to increased focus on improving the efficiency of small-scale, modular plants.

• Green technology progress for a more sustainable future
  Reducing carbon footprint in the synthesis of chemicals is a new challenge, a necessary requirement in the pursuit of sustainable products designed to minimise environmental impacts during their whole lifecycle. So-called "green" technologies for ammonia, methanol and hydrogen are being developed to meet these challenges. Casale, Linde, thyssenkrupp Industrial Solutions, Toyo Engineering Corporation, Haldor Topsoe and Stamicarbon report on some of their latest developments.

• 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.

• Redefining the sustainability of effluent treatment processes
  Nitrogen-rich wastewaters remain a major issue for fertilizer and other industries. Saipem's new electrochemical technology, Spell, is an important step towards the overall objective of zero industrial pollution. A complete engineering review of the technology, its alignment with all international applicable standards, and optimisation has now been concluded and the technology is ready for deployment for the removal of ammonium nitrogen from industrial waters and wastewaters. Saipem discusses the key features of Spell and reports on the first two industrial references.

• 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.
