Nigerian refinery and their capacities

Kaduna refinery = 100,000 barrels per stream day (bpsd) (1975)
Warri refinery = 100,000 bspd (1978) + 25,000 bspd (upgrade 1987) =125,000 bpsd
Port Harcourt = 60,000 bspd (old 1965) +150,000 bspd (new 1989) =210,000 bpsd
Total installed capacity = 435,000 bpsd

How many gallons of petrol and diesel in a barrel of crude oil

A barrel of crude oil = 42 gallons
A barrel of crude oil = 19 gallons of petrol (71.92 litres) [1 gallon =3.785 litres]
= 12 gallons of diesel (45.42 litres)

Total petrol and diesel output at 70% efficiency

@70% efficiency per day =70%*435,000 bpsd = 304,500 bpsd
Amount of petrol produced @ 70% efficiency = 304,500bpsd * 71.92 =21,899,640 litres per day
Amount of diesel produced @ 70% efficiency = 304,500bpsd * 45.42 =13,830,390 litres per day

Average daily consumption

I couldn’t find any recent data for the total petrol consumption of the year 2014, but according to The Petroleum Products Pricing Regulatory Agency (PPPRA) in 2013 the annual consumption of petrol stood at 39.66 million barrels (6.2billion litres).
Convert barrels to litres at (1 barrel =158 litres) [US barrel to litres]
If the yearly consumption (2013) =6.2 billion litres
Daily consumption (2013) = 6.2billion litres/365 = 17,167,890.41 litres per day

The above information is purely based on standard best practices, but after digging further I discovered statistic for refined products in kaduna refinery as follows
No Product Production Rate
1 PMS 3,857 MT/DAY
2 KEROSENE 1,686 MT/DAY
3 AGO [DIESEL] 3,000 MT/DAY
4 ASPHALT 1,796 MT/DAY
5 LAB 91 MT/DAY
6 BASE OILS 657 MT/DAY
7 LPG 620 MT/DAY
8 FUEL 2,100 MT/DAY

This infers that kaduna refinery only produces 3857 metric tons of petrol per day which is about 5.2 million litres daily assuming the density of petrol is 737.22kg/m3. This production value is 2 million litres shy of the internationally accepted rate which could be due to the age of the plants technology.

I hope this will make fp..its really a nice write up. Meanwhile, what do you suggest??

This is really a nice gesture. Thanks for the information

However, your assumption on petrol and diesel output, using gallons of petrol & diesel in a barrel of crude is flawed.

Refinery output doesn't follow that logic.

Refinery output is based on a lot of factors including;
1. The type of crude you're processing.
The type of crude you're processing; whether it is light crude, medium crude, heavy crude or very heavy crude will have specific characteristics. These characteristics, Paraffin, Olefins, Naphthenes and Aromatics (PONA) as a percentage will determine how much petrol, diesel, fuel oil you have in the crude oil.

2. Type of refineries
The type of refinery you're running; whether it is simple refinery, complex or very complex refinery plays a major role in total refinery output. Type will determine if you can actually crack, fractionate and get all of your expected products out.

3. Product requirements
Your product requirements based on demand and supply, most of the time will determine how the refinery will be planned and operated. Product requirements will guide refinery's planning decision, if they need to run an isomerisation unit or an alkylation unit to produce more petrol. Or decision to produce more jet fuel or kerosene.

There some other factors that need to be considered as well

Interesting and very informative piece.

See what I'm thinking: We've been buying fuel at exorbitant prices since the scarcity arrived. We can afford an extra 20 Naira on Fuel. An extra N20 based on your 2013 calculations of 6.2 billion liters would amount to 1.2trillion Naira per year. Over the next 4 years that is 4.8 trillion or $24 billion. If we decide to focus all that money on just 1 thing: rail infrastructure, both intracity and intercity. That way we connect the whole country with over 3000 km of world class rail infrastructure.

This was the Sure-p idea but it was fraught with corruption and scattered across Sectors. Focusing on rail infrastructure would drastically reduce our fuel importation and at the same time save our roads and reduce travel time.

Thanks for this analysis.. many Nigerians including Ministers are out of their depth when it comes to analyzing the problem

Serious stuff never make it to FP.. only pink lips, toolz bleaching, Nyanya posing with his short stumpy legs, Tiwa savage eating kpomo frm dr Sid hands etc

Good analysis. This are the type of people we need in governance not politicians who promise heaven on earth.
