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.
India: Shree Cement has ordered a TRT 5000/8.0 Triplex dryer from Germany’s Gebr. Pfeiffer. The dryer will be used to dry flue gas desulphurisation (FGD) gypsum from a captive coal-power plant for use in cement plants. In the planned dryer plant the moisture of the FGD gypsum will be reduced to a residual moisture of <2%. Artificial gypsum from the dryer will be used at other cement grinding plants in the country. The 50t/hr dryer will be installed at the end of 2018 and is expected to start commercial operation in mid-2019.
Gebr. Pfeiffer is also planning to partially calcine the gypsum in future installations of the dryer. The TRT Triplex dryer uses the uniflow principle, where both material and hot gasses flow in the same direction and pass through the dryer tubes from the centre outwards. Testing at the Gebr. Pfeiffer test station have yielded ‘positive’ results and further installations in other plants are being considered.
Eurocement installing gas power plant at Kavkazcement plant
03 October 2018Russia: Eurocement is installing a 24MW captive natural gas power plant at its Kavkazcement plant in Chelyabinsk. The equipment was purchased from Finland’s Wärtsilä for the Euro15.5m project. Construction of the buildings to house the power plant is expected to be completed in November 2018.
The project is a part of an energy efficiency program that Mikhail Skorokhod, the president of Eurocement, signed with Rashid Temrezov, the head of the Karachay-Cherkess Federal Region, as part of the Russian Investment Forum, in 2018.
At present Eurocement has a power generation capacity of 150MW. It has built captive power plants at its Mordovcement, Sengileevskiy, Peterburgcement and Nevyansk cement plants. Upon the completion of the latest program the company is targeting a power capacty of over 400MW.
Japan: Taiheiyo Cement says that an earthquake that took place in early September 2018 in Hokkaido has had a limited effect upon its business. No injuries to employees were reported. Cement production at its Kamiiso plant is continuing using in-house power generation although the unit is working on saving energy. The 6.7 magnitude earthquake has caused widespread disruption on the island, including knocking out local power generation.
China: Cement producers will be forced to pay fees for captive power plants under new legislation introduced by the National Development and Reform Commission (NDRC). The move was introduced in a draft plan in March 2018 in order to reduce electricity prices for industrial and commercial users, according to Reuters. The new regulations are also intended to cut down on pollution from coal-powered plants used by the cement sector as well as steel and aluminium producers. The size of fees paid by onsite power plants will be decided by provincial governments.
JSW Cement to invest US$150m in UAE
20 July 2018UAE: India’s JSW Cement plans to invest around US$150m in a new integrated 1Mt/yr plant in Fujairah. The project will also include a captive power plant, according to the Economic Times newspaper. The company expects to commission the new plant by December 2019. The project is part of the group’s target to reach a production capacpty of 20Mt/yr by 2020.
India: Sagar Cements has acquired two mini hydroelectric power plants from Sagar Power in Andhra Pradesh. One has a capacity of 4.3MW located at Guntur Branch Canal, Narasaraopet, Guntur District and the other has a capacity of 4MW located at Lock-in-sula, Atmakur, Kurnool District. No amount for the transaction has been disclosed. The cement producer operates two integrated cement plants and one grinding plant.
Kenya: The International Finance Corporation (IFC) has committed US$96m to invest in National Cement towards upgrading a cement plant and building new grinding plants. National Cement’s chairman and chief shareholder Narendra Raval is also expected to invest US$102m into the expansion project, according to the Daily Nation newspaper. The company intends to build two grinding plants in Kenya and Uganda and a new 5500t/day clinker production line at its existing integrated plant in Merrueshi in Kenya. It also plans to build a 8MW captive power plant at Merrueshi.
India: The Fly Ash Council of Maharashtra has asked state power generation company Mahagenco to plan how to give fly ash for free to industrial users. The initiative follows the decision by the state government to adopt its Fly Ash Utilisation Policy, according to the Indian Express newspaper. An official said that the power company would give away fly ash for free within 100km of the plant if it is affordable. The measure was introduced to encourage cement manufacturers and construction companies to use more fly ash by offsetting the transportation cost. At present smaller companies receive the fly ash for no charge.
In 2015 - 2016, Maharashtra used 69% of the fly ash generated in thermal power plants in the state. With an installed capacity of 20,976MW, the state generated 18.6Mt of fly ash during this period, of which 13Mt was used, mostly to make bricks and to build roads. With the new policy the government is targeting a 100% utilisation rate.
India: Nuvoco Vistas plans to increase its specialist cement product range by 5 – 10% over the next two years. The cement producer is undergoing cost cutting initiatives and brand transition exercises, according to the Telegraph of India newspaper. Sales volumes of microfibre-based cement are expected to double to 10% of the company’s product mix. On the production side, the company is considering reducing costs by installing captive power plants and waste heat recovery units.
Nirma Group purchased three cement plants and two grinding plants from Lafarge India with a total production capacity of 11Mt/yr in 2016. Its cement business, Nuvoco Vistas, operates six plants in Chhattisgarh, Rajasthan, Jharkhand and Bengal and Haryana.
