Italy: Exergy has signed a contract with Cementi Rossi for a 3.5MW organic rankine cycle (ORC) waste heat recovery (WHR) system to be installed at the Pederobba plant near Treviso. The scope of the contract includes engineering, design, site erection, commissioning and start up of the power plant and a long term after sales service.

Exergy designed a customized and compact ORC solution to convert approximately 16MWt available from exhaust heat in the clinker cooler into 3.5MW of electricity utilising an air cooled condensing system, a radial outflow turbine as expander and choosing a non-flammable fluid to grant maximum safety during plant operation. The electricity produced by the ORC module will feed approximately the 30% of the energy demand of the cement plant.

“Our ORC WHR systems, leveraging on the higher efficiency of the radial outflow turbine, can help to boost at maximum level the performance of cement plants. For Cementi Rossi in particular we worked to supply a tailor made solution, choosing a non-flammable fluid in the cycle and a very compact plant design with a high level of prefabricated components to reduce costs and time for erection,” said Claudio Spadacini, the chief executive officer (CEO) of Exergy.

India: UltraTech Cement plans to build five waste heat recovery (WHR) units with an investment of US$72.6m. The new WHR units will have a capacity of 63MW and they will take the company’s total WHR capacity to 121MW, according to the Hindu newspaper. It is anticipated that the cement producer will be able to meet half of its power requirements from its WHR plants. They are also intended to protect the company from changes in the price of coal.

India: UltraTech Cement has commissioned a 1.75Mt/yr grinding unit at its Manawar plant in Dhar District, Madhya Pradesh. The main part of the 2.5Mt/yr integrated plant was commissioned in April 2018. A 13MW waste heat recovery unit is also being built at the site.

South Korea: Ssangyong Cement plans to install a waste heat recovery (WHR) unit at its Donghae plant in Gangwon. The upgrade will be operational by August 2018, according to the Maeil Business Newspaper. The new unit is expected to save the cement producer about 33% of its electricity costs or US$24m/yr.

The investment is the largest that the cement producer’s owner Hahn & Company has approved since it took control. The WHR will work with an energy storage system (ESS) that was installed in March 2018. The ESS saves power consumption by storing energy during the night and then using it during the day. The 22MWhr storage system is power by powered by 2880 batteries. The company said that it would save it at least US$2.4m/yr.

Ssangyong Cement’s Donghae plant is one of the largest in the world with a cement production capacity of 11.2Mt/yr across seven production lines. It occupies an areas of 11.3MM².

Italy/Switzerland/Turkey: Turboden has released information on its latest waste heat recovery (WHR) projects using its ORC turbogenerator for cement plants in Turkey, Switzerland and Italy.

In Turkey CTP Team and CTN Group have signed an order with Turboden for the supply of a 7MW ORC WHR unit with air cooled condenser to be installed in Çimko Çemento Narli’s plant. Turboden says that since the plant is located in an area where there is no water available for the cooling system, the ORC technology offer advantages over steam technology.

In Switzerland CadCime SA and LafargeHolcim have ordered a 1.3MW WHR unit that recovers heat from the existing pressurised water circuit, used for the district heating network. The order is the third from LafargeHolcim for an ORC unit from Turboden.

In Italy a 2MW WHR plant with direct heat exchange is being installed at Cementi Rossi’s plant. Start-up is schedule for the second quarter of 2018. This project received an award from the European Commission under the framework of Horizon 2020, whose main objective is to develop new solutions to recover waste heat in energy intensive industries such as cement, glass, steelmaking and petrochemical and transform it into electric energy.

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.

India: Gujarat Sidhee Cement has commissioned a 5.5MW waste heat recovery plant at its Sidheegram plant in Gujarat. The project has a budget of US$10m. Power generated from the unit is expected save the plant US$2.6m/yr .

India: The board of Mangalam Cement has approved plants to build a 11MW waste heat recovery unit at its Morak plant in Rajasthan. The subsidiary of BK Birla Group operates a single integrated plant.

India: Nirma Group’s subsidiary Nuvoco Vistas plans to invest US$157m on captive power plants and waste heat recovery systems for three of its cement plants in Chhattisgarh, Jharkhand and Rajasthan. The cement producer plans to save around US$15m from the upgrades over the next two to three years, according to the Hindu newspaper. Nirma Group purchased three cement plants and two grinding plants from Lafarge India with a total production capacity of 11Mt/yr in 2016.

Namibia/China: Sinoma Energy Conservation has signed a contract with China’s Asia-Africa Business Management (AABM) to build a 4.5MW waste heat power plant. The power unit will support a 2500t/day cement production plant that AABM and local company Whale Rock Cement plan to build as a joint venture. The cement plant project was first announced in 2015.
