Abstract: Water- It is one of the most important resources to be used in almost every kind of industrial process.
Here, mainly water usage in hydrocarbon sector would be discussed i.e. treatment of raw water and
treatment of the waste water effluent generated from various process units to ensure that eventually,
only treated water is released into natural water courses and is also being recycled and reused in the
refinery plant. My goal was to learn the treatment strategy and basic design components and process
so that I can further upgrade my knowledge in this field, learn new techniques, use and implement it
for treatment of water in industries. In refineries, extracted crude oil is of no use unless it is
converted into valuable marketable products therefore, for manufacturing processes water of specific
quality is required to be used and further released wastewater is required to be treated before getting
released into natural water courses.Nowadays, it should be tried to use the treated water within the
refinery complex so as to minimize the risk of polluting natural water bodies.
RAW WATER TREATMENT PLANT: The RWTP scheme incorporates units which remove principal
contaminants such as turbidity, total suspended solids and organic matter. Treated water obtained
will be used for demineralization (DM) plant feed, cooling water make up, service water use,
drinking water for refinery and township area, fire water etc. The total design criterion of RWTP
depends upon the amount of water to be treated and the flow rate and therefore it differs for every
plant.
EFFLUENT TREATMENT PLANT: This plant is basically designed to treat the wastewater
released from various process units. It consist of principal contaminants such as free and emulsified
oil, BOD,COD, TSS, phenols, sulphides, total nitrogen, etc. Initially, oil is removed and then it is sent
for further treatment in biological system and then further for polishing if required.
The main objectives are listed below:
1. To study various processes involved in industrial water treatment and industrial effluent
treatment plant in hydrocarbon sector.
2. To study basic designing of industrial water treatment and industrial effluent treatment
plant in hydrocarbon sector.
