Petroleum coke utilization for cement kiln firing

Abstract

Pulverized delayed petroleum coke imported from the USA is the prime energy source for both 5000 MTPD modern dry process clinker lines operating in the Nesher Israel Cement Enterprises' Ramla plant. Both the first line-RDL-1-operating since 1995 and the second one-RDL-2-operating since 1999, were designed and guaranteed for firing of eighty percent of energy as petroleum coke, the rest being bunker C heavy fuel oil. The article discusses the different points being taken care of at the design phase and outlines the parameters of the actual operating mode under which both lines practically fire hundred percent of energy as petroleum coke.
