University of Mons study finds ‘optimum’ solvent for CCS 04 December 2019
Belgium: A team of researchers from the University of Mons in Hainaut province has concluded a study in the use of amine-based solvents for carbon capture on between 20% and 60% CO2 flue gas with funding from HeidelbergCement and the European Cement Research Academy. Lab tests and industrial-scale simulations showed that the solvents lowered regeneration energy, equivalent work and operating costs of carbon capture across the CO2 concentration range of flue gases tested.
Ash washing begins at Taiheiyo Cement waste incinerator 03 December 2019
Japan: Taiheiyo Cement has installed an ash washing facility at a waste incineration plant in Kumagaya, Saitama prefecture for desalination and lowering of chloride content. After rinsing, the installation will supplement cement production at Taiheiyo Cement’s 1.8Mt/yr integrated Kumagaya plant with up to 69,400t/yr of ash. The total cost of investment was US$7.17m.

UAE: Figures from Iran’s Qeshm Free Trade Zone show a deficiency in domestic cement production in the UAE, as 48,000t of cement have been shipped to the country in the six months ending 21 September 2019. Cement from across the Gulf helps serve the consistently growing needs of the country’s construction industry.
Heliogen looks to heat cement pre-calciners straight from solar 03 December 2019
US: California-based Heliogen has developed concentrated solar-thermal plants (CSPs) with the ability to focus sunlight to generate temperatures over 1000°C by micro-adjusting mirrors using computer technology. It has now engaged Parsons Corporation to build arrays of its CSPs for installation in cement pre-calciners. Requiring 900°C heat, these represent the largest part of the industry’s CO2 output. The technology will firstly reduce this by replacing fossil fuels with a clean heat source, which moreover entirely bypasses the electrical grid. Heliogen CEO Bill Gross says that the installations will make carbon capture and storage (CCS) of the remaining CO2 emissions from the conversion of limestone to lime easier by removing other pollutants. Heliogen is now targeting 1500°C from its CSPs, which would enable them to supersede cement fuels in kilns.
