The visit was part of an assessment to prepare Ibeto Cement for a listing on a stock exchange in the US, according to the This Day newspaper. Cletus Madubugwu Ibeto, the chief executive officer (CEO) of Ibeto Group said that Chinese contractors were due to work on upgrading the plant to a production capacity of 6000t/day with a 45MW waste heat recovery unit.

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.
Turboden provides update on waste heat recovery projects for cement plants in Turkey, Switzerland and Italy
15 May 2018Italy/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.
