The Circular Economy: Carbon Recycling and the Steel Industryy
By A. Fleischanderl, T. Plattner, P. Puschitz,
Primetals Technologies Austria GmbH, P. Nair, M. Schultz, LanzaTech Inc.
LanzaTech and Primetals Technologies are enabling a resource revolution in the steel industry that supports a circular economy, by decoupling the use of natural resources and the generation of waste from economic growth. Microbial fermentation of carbon and hydrogen-rich off-gases, such as coke oven gas, blast furnace top gas, direct reduction gas and converter BOF gas to produce ethanol or other basic chemicals, substantially mitigates CO2 emissions while simultaneously reducing NOx, SOx and particulate emissions. The fuels and chemical products produced in this manner deliver superior economic returns. The ethanol product has up to a 70% reduction in greenhouse gases (GHG) compared to conventional gasoline, and reductions between 30% and 50%, per MJ energy recovered, when compared to combustion of those gases for power generation.
Efforts for cooling water saving in a steelmaking facility
By S. Cattarino, M.Colautti, S. Mansutti, PERT SRL, Tavagnacco (UD), Italy
A new steelmaking facility has been built in a desert region for the production of 1.500.000 t/y of steel billets. In a steel plant, the water resource is vital to the operation of the systems since water is used as cooling fluid for equipment and steel. Although referred to as “auxiliary equipment” the Water Treatment Plant is essential to ensure the continuity of production. And on average no particular attention to water saving, an increasingly felt need, is paid in designing. If water resources are limited, a non-conventional approach is needed to design a water treatment plant with low water consumption. The consumption limits imposed by the Customer are 180 m3/h as average daily water flow, against usual consumption of normal plants of 600 m3/h. An hourly peak consumption lower than 250 m3/h was also required. The cooling water capacity demand is approximately 10.000 m3/h, divided between circuits for several users. Thermal powers to dispose of are in the order of 200 MW. The solution adopted, in order to reduce raw water consumption downto approx. 120 m3/h on a daily average, differs from traditional approaches due to the following aspects: - Use of equipment with low or negligible water consumption (hybrid-cooling towers and dry coolers) - Study and application of a plant for the treatment and recovery of the drains (drain recovery DR-WTP). This allowed to respect the limits imposed by the availability of water on site and to maintain a safety margin for a future planned upgrade of the plant. The solution finally results also economically interesting, especially thanks to the water chemical conditioning saving.

Safe retraction without loops: a new energy supply system from igus
By Our News Bureau
The motion plastics specialist igus has developed a lightweight and cost-effective concept for the automatic retraction of energy chains allowing further advances in robotics. Besides carrying energy, data and media cables, industrial robots nowadays also frequently carry supply hosesfor rivets or screws. The new triflex RSE system prevents looping of the energy chain, allowing these materials to be safely supplied to the end of the robot arm.
