CHAPTER I

General Description Of Calcined Petroleum Coke

(CPC) a. Raw Material

Calcined Petroleum Coke produced from raw materials Green Coke. Green coke or also known as green petroleum coke, a material derived from residue oil refining process. Green Coke, produced in oil refineries. Processing of solid carbon compounds using Delayed Cooking Unit is capable of converting heavy oil (short residue) into green coke. Green Coke has a heavier fraction when compared to gasoline. Due to the lower calorific value of between 7500-8500 K.cal/ Kg, but when compared with coal (K.cal/ 5000 to 6000 Kg), the calorific value higher green coke.

Judging from grade, petcoke classified into two types, namely fuel grade coke and anode grade coke. Fuel-grade coke is used as fuel, while The anode grade coke used in the aluminum smelting industry, steel and

titanium. The main difference of fuel grade coke with anode grade coke is a metal

element content and sulfur levels. At the anode grade coke, metals and sulfur

content should be very low.

Green Petroleum Coke

There are several types of pet coke is needle coke, honeycomb coke, sponge

coke and shot coke. Needle coke and coke honeycomb classified in anode grade

coke, while the sponge coke and shot coke classified as fuel grade coke.

Calcination of the green will produce calcined petcoke petcoke, this calcination

process removes moisture content and volatile matter content and changing

the crystal structure of pet coke.

In general, the processing of calcined coke product can be classified into tree

factors such as the following picture:

b. Petroleum Coke Calcining

Petroleum Coke Calcining is a process whereby green or raw petroleum coke is

thermally upgraded to :

Remove associated moisture and volatile combustion matter Improve critical physical properties like

Electrical conductivity Real density Oxidation characterictics

CHAPTER II

Application of CPC & it’s Market in Industry

Market of CFC Calcined Petroleum Coke (CPC) is important industrial commodity linking the oil

refining, metallurgical/chemical with solid material industries and an aluminium

and titanium dioxide production.

The application for Calcined Petroleum Coke (CPC) is used in this following

industries :

The Aluminium industry More than 70 percent of all CPC used to produce anodes for the smelting of alumina into aluminum.

Titanium Dioxide Industry Calcined petcoke is used in the production of titanium dioxide (TiO2), a naturally occurring mineral that is used as a pigment for plastics, paints, sunscreen and food coloring. Two significant usefulness of titanium dioxide is as a replacement for lead in paint and as a bleach paper.

The Steel Industry

Calcined petcoke as recarburizer in the steel industry recarburizer used to adjust the carbon content.

Application of CPC in Aluminium industry

The use of CPC in Aluminium industry is to produce anode for reduction process in

Aluminium process. Liquid Aluminium is produced by electrolytic reduction of

alumina (AL2O3) dissolved in an electrolyte (bath) mainly containing Cryolite

(Na3AlF6). The chemical reaction can be written as :

where Carbon ( C ) use anode Carbon made from CPC as reductor

Aluminium Production use Anode (Carbon) from CPC

The anodes used are termed as prebaked anodes which are made from a mixture

of Calcined Petroleum Coke, aggregate and coal tar pitch binder moulded into

blocks and bake in separate anode baking furnace at about 1120 C. An Aluminium

rod with iron studs is then cast or rammed into grooves in the top of the anode

block in order to support the anode and the conduct the electric current to the

anode when it has been positioned in the cell.

Application of CPC in Titanium Dioxide (TiO2) industry

In opposition of the popular belief, the most widely used titanium product is not the titanium metal and alloys, but rather is the titanium dioxide (TiO2) pigment that provide whiteness and opacity to a vast range of everyday products from coatings and plastics, to inks and even as flux in glass manufacture, filler in paper, rubber industries, cosmetics and food. Annually more than 4.5 million t of TiO2 are produced worldwide and only about 4%~5% is used to produced metallic titanium.

Titanium Dioxide (TiO2) pigment are produce from variety of ares by two different process : The Sulfate Process (about 40% use in industry) The Chloride Process (about 60% use in industry)

At the chloride process, TiO2 produces by using Carbon as reductor, shown in this

reaction :

TiO2 is simple inorganic compound produced as a pure white powder (known as

titanium white). This pigmen can be use, in most of its application, as a pigment to

scatter light, provide whiteness & opacity product in coating, plastic and paint,

printing inks and paper, pharmaceutical and cosmetic industries, textile and food

industry.

Application of CPC in Steel Industry

The Calcined Petroleum Coke is widely use in Steel industry. It is use as recarburizer in the steel industry. Recarburizer used to adjust the carbon content in the steel making.
