Lafarge Canada to test carbon capture plans with Inventys and Total at Richmond cement plant
29 May 2019Canada: Lafarge Canada plans to develop and demonstrate a full-cycle solution to capture and reuse CO2 from a cement plant. Project CO2MENT will demonstrate and evaluate Inventys' CO2 capture system and a selection of CO2 utilisation technologies at Lafarge's Richmond cement plant in British Colombia over the next four years. This project is being led by Inventys in partnership with Lafarge Canada and Total. It also received financial support from CCP (CO2 Capture Project), the Province of British Colombia and Canada's federal government through the National Research Council of Canada Industrial Research Assistance Program (NRC IRAP).
"At Inventys, we see a real opportunity to build a CO2 marketplace where tonnes of CO2 are traded between emitters and users," said Inventys president and chief executive officer (CEO) Claude Letourneau.
Phase I of Project CO2MENT, the Contaminant Program, will attempt to reduce harmful organic and inorganic substances, such as sulphur dioxide, dust and soot, as well as nitrogen oxides, from cement flue gas. Phase II, the CO2 Capture Program, will separate the CO2 from flue gas using a customised-for-cement version of Inventys' carbon capture technology at pilot scale. Phase III, the CO2 Reuse Program, will prepare post-combustion CO2 for reuse and support the economical assessment and demonstration of CO2 conversion technologies onsite, such as CO2-injected concrete and fly ash.
Funding for the first two phases is complete and development of Phase I is underway. Phase I will begin operation in 2019 followed by Phase II and III in 2020.
US: Charah Solutions has opened a terminal for fly ash in Hopedale, Massachusetts. The unit has railway access and is connected to local road networks. It is intended to serve customers in New England.
Charah Solutions says that the terminal will increase the availability of fly ash from its MultiSource materials network locations in the South, New England, the Midwest, the Rocky Mountains and California. These locations supply Class C and Class F fly ash for ready mix concrete producers and other customers.
Bangladesh Cement Manufacturers Association calls for clinker import duties to be reduced
24 April 2019Bangladesh: The Bangladesh Cement Manufacturers Association (BCMA) has asked for import tariffs on clinker to be reduced. In a letter to the National Board of Revenue (NBR) it requested that the duty be cut to either US$2.40/t or a fixed rate of 5%, according to the Dhaka Tribune newspaper. Importers pay around US$6.00/t at present. The BCMA argues that the cement industry is paying more than other industries for its imports.
The association has also called for value added tax (VAT) on raw materials to be cut to 5% from 15%, reducing advance income tax to 2.5% from 5% and exempting regulatory duties for fly ash and import duties for cement bulk carriers.
Elektroprivreda Srbije builds river terminal in Serbia
09 April 2019Serbia: Elektroprivreda Srbije, a government-owned power company, has completed a Euro14m terminal on the River Danube for its Kostolac B coal-fired power plant. The unit will be use to transport 105,000t/yr of synthetic gypsum and 157,000/yr of fly ash. It will also process limestone. The terminal was built as part of the first phase of a credit arrangement between Serbia and China.
Spain: Endesa sold 0.3Mt of fly-ash from its Carboneras power plant in Almeria to cement companies in the UK and North America in 2018. The energy company also sold fly-ash to the nearby LafargeHolcim Carboneras cement plant, according to La Voz de Almería newspaper. The company has also sold 30,00t of slag and 60,000t of gypsum from its limestone plant.
US: Charah Solutions has installed its MP618 thermal beneficiation technology at its terminal in Sulphur, Louisiana. The upgrade is intended to improve the quality of fly ash and to increase its supply of marketable fly ash to concrete producers. The proprietary process reduces loss on ignition, ammonia, activated carbon and moisture in fly ash.
The company hopes to provides concrete product producers and builders with a source of Class F fly ash to support a growing number of construction projects in the greater Lake Charles and Sulphur region. The Sulphur terminal is Charah Solutions’ second barge-supplied location in southern Louisiana. Its LaPlace, Louisiana terminal currently serves customers in Louisiana, Mississippi and Alabama.
China: Anhui Conch has continued a cement sale and purchase agreement with Jiangsu Conch Building Materials by entering into a new contract worth US$364m. Subsidiaries of Anhui Conch based in east China will sell a total of 7.5Mt of cement products to Jiangsu Conch, a non-wholly owned subsidiary of Anhui Conch, in 2019. Additionally, three of Anhui Conch’s subsidiaries in Shanghai region will procure 0.13Mt of fly ash and 70,000t of flue gas desulphurisation gypsum from Jiangsu Conch Building Materials in 2019 for a value of around US$3m. The deals follow a similar arrangement for Anhui Conch to sell cement to Jiangsu Conch in 2018.
Madhya Pradesh power stations struggling to dispose of fly ash
06 December 2018India: Power stations owned by the Government of Madhya Pradesh are struggling to dispose of fly ash. The power companies were required to dispose of all fly ash in applications such as cement production or construction projects by the end of 2017, according to the Times of India newspaper. However, less than 20% of fly ash has been disposed of from the Shri Singaji Thermal Power Station (SSTPS) and only 20% fly ash has been disposed of at the Satpura Thermal Power Station (STPS).
An employee of a power plant quoted by the newspaper said that the power companies were able to dispose of fly ash where cement plants were nearby but that they found it a ‘great struggle’ elsewhere. A K Nanda, the managing director of the Madhya Pradesh Power Generation Company, said that the STPS had received no interest for an expression of interest since mid-2018. He added that the company was also approaching cement-based industries through social-media channels.
Lehigh Hanson signs fly ash deal with SaskPower
05 December 2018Canada: Lehigh Hanson Materials has signed a deal with SaskPower to give it exclusive rights to fly ash from the coal-fired Shand Power Station near Estevan in Saskatchewan. This expands on an existing 10-year agreement signed in 2012 to market Boundary Dam Power Station fly ash. An estimated 0.22Mt/yr of fly ash will be sold from the Boundary Dam and Shand Power stations.
US: Charah Solutions has launched a proprietary fly ash thermal beneficiation technology that improves the quality of fly ash. It says that its new MP618Multi-Process technology reduces loss on ignition (LOI), ammonia, activated carbon and moisture in fly ash.
The technology allows for the beneficiation of both wet and dry fly ash. It advantages include lower costs, self-contained environmental controls that can be deployed in weeks, as opposed to years and a modular design that can be scaled up or down to increase production based on market demand.
MP618 can process both wet and dry fly ash. It can be installed at both operating and non-operating power plants, regardless of whether the fly ash is current production or legacy ash stored in ponds or landfills. The technology also allows for the processing of kiln dust to remove mercury for emissions regulations compliance. With the introduction of MP618, Charah Solutions expects to increase its supply of marketable fly ash to concrete producers and add greater value to its utility customers.
“MP618 will expand our MultiSource materials network, a unique distribution system of more than 30 nationwide sourcing locations, and improve our ability to provide a continuous and reliable supply of supplementary cementitious materials, including quality fly ash and slag cement, for ready mix concrete producers and other customers throughout the US,” said Scott Ziegler, Vice President of Byproduct Sales at Charah Solutions.
