POLLUTION APPLICABLE TO THE PETROLEUM INDUSTRY

POLLUTION APPLICABLE TO THE PETROLEUM INDUSTRY

In the petroleum industry there are three stages of pollution, which are during:

1. Crude oil production/drilling
2. The transportation of crude products from oil wells/Refineries to different geographical locations.
3. Refining processes.

Environmental pollution by the petroleum industry can be due to waste, solid, waste water and air pollutants.

Waste from petroleum industry originates from the following processes

S/N	REFINING PROCESS	ASSOCIATED LIQUID WASTE
1.	Distillation	Effluent with ammonia, H2S and Phenols.
2.	Desalting	Sulphides, Nacl, Phenols etc
3.	Vacuum Distillation	Phenols and oils
4.	Naphta Hydrotreating	Sour condensate
5.	Catalytic Hydrotreating	Ammonia Cyanides, Hydrogen, Sulphide.
6.	Catalytic Thermal Cracking	Ammonia, sulphide, Phenols, Hydrogen.
7.	Hydrocracking	Ammonia
8.	Catalytic  Alkylation	Alkalis from washings and acids from drains.
9.	Solvent Processes	Solvent like Copper, Sulphides, Phenols etc.
10.	Treating Processes	Organic and inorganic pollutants emulsified oil.
