Hence particulate emissions are always lower as compared to coal. All About Pet Coke What is Petcoke ? Cocking is a thermal cracking process characterized by long residence time and the production of petroleum coke (Petcoke), a heavy carbon residue. Petcoke is produced by thermal cracking of vacuum residue that is produced from crude oil. In a petroleum refinery, atmospheric and vacuum distillation processes remove from the crude the oil the components that boil up to about 500oC. The distillation process separates the lighter part of the crude oil into fractions which are then processed into useful refined products such as LPG, petrol, kerosene, diesel, etc. The part of the crude oil which does not boil off during the distillation process even under vacuum is known as the vacuum reside. The vacuum residue consists of heavy, viscous, complex hydrocarbon molecules. The coking process converts the vacuum residue into gas, liquid and solid products. In delayed coking, the heavy feedstock is heated in a tube still and pumped as rapidly as possible to insulated drums where it the large molecules are cracked into smaller molecules and residue, producing gas, liquid products and coke. The term 'delayed' comes from the delay between heating and coking. As coke buiilds up in the drum, the lighter products of cracking are recovered as overhead vapours and are taken to a fractionator for separation into various products. Petcoke yield is mainly dependent on the carbon content of the feedstock, while the structural quality of the Petcoke is influenced chiefly by the type of feed, i.e., virgin crude or cracked products. Fuel grade Petcoke is produced from vacuum residues that have high sulfur contents. High sulphur Petcoke is used as fuel whereas low sulphur Petocoke is used in producing anodes. Fuel grade Petcoke generally replaces iignite and coal.

CALCULATION OF RUNNING COST
DEAR SIR IN THE PET COKE FURNACE THE RUNNING COST OF FUEL IS VERY LESS
THEN OTHER FUEL LIKE ELECTRICITY ,DIESEL, GAS ,F.O. ETC. THE CALCULATION
OF THE COST EFFECTIVENESS ARE AS FOLLWS:
LET US ASSUME IF YOU USE ELECTRIC FIRED FURNACE AND YOUR RUNNING COST
WILL BE AS FOLLWS:
YOUR 500 KG FURNACE WILL BE IN 70 KW THEN THE CALCULATION ARE AS
FOLOWS:-
A). CONSUMPTION OF ELECTRICITY IN 500 KG ELECTRIC FURNACE IN 24 HOUR WILL
BE 70*24= 1680 UNITS.
AND LET US SUPPOSE THE UNIT COST IS RUPPES 6.5 RUPEES EACH UNIT SO TOTAL
CONSUMPTION OF ELECTRICITY IN 24 HOURS IN A DAY WILL BE 1680*6.5= 10920
RUPEES.
TOTAL RUNNING COST IN A SINGLE DAY IF RUN FOR 24 HOURS WILL BE 10,920
RUPEES.
B). IN THE SECOND CASE IN PET COKE FIRED FURNACE TOTAL CONSUMPTION OF
PET COKE IN A 500 KG DIE CASTING FURNACE WILL BE 550KG TO 600 KG IN 24
HOURS AND PET COKE MARKET PRICE IS 13 PER KG.
SO TOTAL RUNNING COST ON 500 KG MELTING FURNACE MATERIAL IN 24 HOURS
WILL BE 600 KG*13= 7800 RUPEES.
SO TOTAL SAVING IN THE PET COKE FURNACE WILL BE 10920-7800= 3120 RUPEES IN
A DAY.

The Petroleum Coke also known as Petcoke, has several remarkable features from the usage
point of view that are:
Petcoke can be a good replacement of coal/lignite. It can be used in blend form along with coal/lignite or 100% in AFBC/CFBC boilers. Ash content in Petcoke is much lower than coal/lignite. Hence particulate emissions are
always lower as compared to coal.
All About Pet Coke
What is Petcoke ?
Cocking is a thermal cracking process characterized by long residence time and the production
of petroleum coke (Petcoke), a heavy carbon residue. Petcoke is produced by thermal cracking
of vacuum residue that is produced from crude oil.
In a petroleum refinery, atmospheric and vacuum distillation processes remove from the crude
the oil the components that boil up to about 500oC. The distillation process separates the
lighter part of the crude oil into fractions which are then processed into useful refined products
such as LPG, petrol, kerosene, diesel, etc. The part of the crude oil which does not boil off
during the distillation process even under vacuum is known as the vacuum reside. The vacuum
residue consists of heavy, viscous, complex hydrocarbon molecules.
The coking process converts the vacuum residue into gas, liquid and solid products. In delayed
coking, the heavy feedstock is heated in a tube still and pumped as rapidly as possible to
insulated drums where it the large molecules are cracked into smaller molecules and residue,
producing gas, liquid products and coke. The term 'delayed' comes from the delay between
heating and coking. As coke builds up in the drum, the lighter products of cracking are
recovered as overhead vapours and are taken to a fractionator for separation into various
products.
Petcoke yield is mainly dependent on the carbon content of the feedstock, while the structural
quality of the Petcoke is influenced chiefly by the type of feed, i.e., virgin crude or cracked
products. Fuel grade Petcoke is produced from vacuum residues that have high sulfur
contents. High sulphur Petcoke is used as fuel whereas low sulphur Petocoke is used in
producing anodes.
Fuel grade Petcoke generally replaces iignite and coal.
How does Petcoke compare with Lignite ?
Lignite is a natural product and a fossil fuel Lignite is found at and around Panandro, Rajpardi
and Bhavnagar in Gujarat Lignite is the first stage of conversion of wood and biomass product
into coal. It has very high moisture content about 30-40%. The volitile content is also very
high, about 30-40%. Fixed carbon is less unlike Anthracite and Petcoke. Sulphur content is
3.0-5.0%. Calorific vlaue of lignite is very low, about 2800-3800 kcal / kg where as calorific
value of Petcoke is 8200-8500 kcal / kg. So, on heat equivalent basis, 2.5 to 3 kg of lignite is
replaced by 1 kg of Petcoke. It means that whereas for the same heat equivalent just kg of
Petcoke with about 75 gm of Sulphur is injected into the furnace. Hence, the generation of
SO2 with lignite is 1.4 times higher as compared to Petcoke.
How does Petcoke compare with Coal ? Coal is also a natural fossil fuel. Domestic coal is mainly in Central and Eastern India and in
the North East. The ash content in domestic coal is very high- it can go up to even 45%. Coal
is also imported into India mainly from Indonesia and South Africa. The ash content in
imported coal is generally about 2 -15%. One of the main problems with the use of solid fuels is the emission of suspended particulate
matter (SPM) into the atmosphere along with the flue gasses. Against an ash content of about
15% in imported coal and about 35-45% in domestic coal, the ash content in Petcoke is less
than 1% - typically about 0.6-0.7%. Thus, the main problem in furnaces and boilers i.e.
emission of suspended particulate matter, is non-existent with Petcoke, as compared to coal.

WHY TO USE PET COKE? 1. Very High Cost Advantage against Gas / Furnace Oil. Also Gives Competitive Cost
Advantage against Lignite. 2. Nil Ash Content (< 1%). So Less Pollution related problem due to the same as well as No
Disposal Problem. Also Due to Nil Ash content in Pet Coke unburnt material is reusable. This recovery of Unburnt is not possible in case of lignite due to high ash content.
3. Low Volatile Matters: Due to low volatile matters handling of Pet Coke is very easy rather than lignite as it easily gets burnt due to high volatile matter even in heavy sun light.
4. High GCV: As Pet Coke has high GCV, the actual material quantity to be handled reduces to 2 to 3 time than that of Lignite. Also Grinding requirement of Pet Coke is much lesser than that of Lignite. So ultimately it reduces the operating and material handling costs.
5. Manufactured Product: one can get Consistent Quality. 6. As Pet Coke is a Petroleum Product; it does not suck moisture by self.
So, on basis of above benefits, Pet Coke is much beneficial than Gas/FO, coal and Lignite.
