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.
Odisha state government announces 27 projects 03 December 2019
India: The government of the state of Odisha will invest US$1.25bn in infrastructure development, including construction of several industrial facilities. These will include a 1.0Mt/yr integrated plant owned by JSW Cement subsidiary Shiva Cement and a total of 4.0Mt/yr grinding capacity in new Shiva Cement and Shree Cement plants. The projects will source their cement from Odisha’s existing installed capacity of 7.3Mt/yr, consisting of 3.8Mt/yr integrated and 3.5Mt/yr grinding capacity at plants owned and operated by Dalmia Bharat’s OCC India, Toshali Cement, UltraTech Cement and Lafarge Holcim’s ACC Cement.
Wikov and Premium Transmission sign partnership agreement 03 December 2019
India: Czech Republic-based Wikov has announced the conclusion of an agreement with Premium Transmission with the aim of bringing its gearboxes to the Indian market. The agreement entails Premium Transmission assembling Wikov gearboxes to install in projects across the country.
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.
Vietnam’s November cement production rises by 9.6% year-on-year 02 December 2019
Vietnam: The General Statistics Office has reported an estimated 9.6% year-on-year rise in cement production in November 2019 to 8.7Mt from 7.9Mt in November 2018. Vietnam News Brief Service has reported that, if December delivers on the previous month’s volumes, this would yield a production total for 2019 of 96.6Mt, up by 7.1% from 87.9Mt in 2018.
Lafarge Cement Zimbabwe plans dry mortar production line 02 December 2019
Zimbabwe: LafargeHolcim subsidiary Lafarge Cement Zimbabwe has announced a planned investment of US$15.0m in a dry mortar production line to diversify its product base. All Africa has reported that construction will begin in January 2020.
The company stated that it will conclude registration of a US$28.5m loan from the reserve bank of Zimbabwe before the end of 2019.
KHD shares test success with NOx emission reducer 02 December 2019
China: KHD has reported NOx emissions consistently below 50mg/Nm3 at Tianrui’s 2.0Mt/yr Weihui integrated cement plant in Henan province, where its Pyroredox gasifying reactor has been installed between the kiln inlet chamber and preheater calciner. The NOx reduction after several months of operation was 66%, while reagent usage fell by 78% compared to with the plant’s selective non-catalytic reducer without a Pyroredox fitted. No extra power or fuel was used and production was unaffected. The Pyroredox requires two to four weeks’ downtime for its installation and is now operational at multiple cement plants across China.
New Panamanian regulations to enter force on 3 December 2019 02 December 2019
Panama: New technical regulations for cement composition and behavioural characteristics will enter force on 3 December 2019. All packaging must display the contents’ net weight, country of origin, cement type and production date. La Estrella has reported that the legislation gives enforcing power to the Ministry of Commerce and Industry’s Directorate General of Industrial Technology Standards (DGNTI), the Consumer Protection and Competition Defence Authority (ACODECO) and customs authorities.
