Order received from Saudi Arabia for large cement plant
Ishikawajima-Harima Heavy Industries Co., Ltd. (IHI) and Marubeni Corporation (a Japanese trading house) jointly received an order from Qassim Cement Co. (QCC)[*1] of Saudi Arabia for construction of a cement plant with a production capacity of 4,500t/d. QCC is a leading cement manufacturer in Saudi Arabia, with which two Japanese companies signed the contract on Sept. 30, 2003. The contract is valued at about 30 billion yen.
Demand for cement is now sharply increasing in Saudi Arabia. QCC has thus launched the project to increase production capacity by adding to existing facilities -- one 2,750t/d plant and two 2,200t/d plants. The contract will be carried out on a full turnkey basis -- design, manufacture, procurement, civil engineering, installation, and test running. The plant includes a crushing mill, preparation equipment and silos, calcining equipment, and a shipping facility. The plant will be completed in April 2006.
IHI previously completed one of the two 2,200t/d plants with the NFS (new suspension flush furnace)[*2] system in 1987 for QCC, and remodeled the other 2,200t/d plant (constructed by another contractor) into the IHI NSF system in 1997. The customer has highly evaluated the IHI NSF calcining method that increases the product quality with lower fuel consumption.
The NSF system consists of a flush furnace and the five-stage cyclone, the key equipment for a cement plant, which is used for calcining clinker with low fuel consumption and NOx emissions. The NSF system is the improved model derived from the original SF system developed in 1972. The new cement plant for QCC uses a method to suppress emission of dust and fumes and can also produce pozzolana cement (pozzolana is a type of volcanic ash).
A 3,300t/d IHI NSF type cement plant is now under construction for the Yemen General Corporation for the Manufacturing and Marketing of Cement, and in Viet Nam, IHI completed expansion work of a 1,750t/d cement plant up to 3,500t/d capacity for the Vietnam National Cement Public Corporation in June 2003. The IHI NSF system has been adopted for 112 cement plants worldwide, gaining a high reputation among users. IHI will continue to increase the cement plant business in the Middle East and S.E. Asia, targeting 20 billion yen contracts per year.
