Rain CII Carbon LLC calcined petroleum coke producers


Petroleum coke is produced in refinery coking units where the vacuum distillation residues of crude oils are thermally cracked and separated into gases, liquids and coke. Rain CII's commitment to quality begins with careful selection of raw materials (green coke) from petroleum refineries. Green coke must meet Rain CII's standards for structure, size, volatile content and purity.

Green cokes are received at the calcining plants where they are placed within our designated storage facilities. The
	cokes are separated based on type and quality. Ample green coke storage capacity permits flexibility in blending different qualities of green coke to meet customer requirements before the calcining process begins. ^TOP

Rain CII uses statistical process control to calcine the blend of green cokes to an optimum level to meet a customer's particular needs. Each customer shipment is developed through close communication, careful planning, and technical understanding of particular needs.

Our calcining kilns are refractory lined cylinders 55 to 65 meters in length and about 3 meters in diameter. As the coke moves through the revolving kiln, it is progressively heated to about 1350 °C. Water and volatiles are driven off
	and the remaining carbon rich solid is partially graphitized, producing a structure suited for anode production at aluminum smelters. The calcined coke is cooled with purified water and moved by conveyor to product storage. ^TOP


The calcined coke is transported to storage areas specifically designed for further blending.	^TOP


	During vessel loading, the coke is blended from separate tanks and silos (Chalmette, Moundsville), or from separate storage areas (Gramercy, Lake Charles). The end result is a uniform, consistent quality blend of coke.

At the customer location, the coke is used to make anodes which are consumed in the electrolytic process for making aluminum.
