General classification of petroleum products for storage.

Plot plan is a spatial arrangement of equipment considering proper flow sequence, system grouping, safety, statutory requirements, maintenance, operation, erection and construction with logistical economy.

Hydrocarbon processing and handling plants are inherently hazardous involving large and complex processes and substantial risk potential hence a careful consideration shall be given while developing a plot plan.

Safety ensures proper protection and safe operation- Lifetime.

Apart from this, local rules and regulations pertaining to State and local industrial requirement should be taken into consideration.Static and Mobile Pressure Vessel (SMPV).Petroleum Act 1934 (Act N0.30 of 1934) Along with The Petroleum Rules.However these are to be relooked based on geographical location:

Following are the key statutory requirements (India).Safety considerations/Statutory requirements.Identification of storage based on fluid stored.Neighbouring commercial and residential property.Design Considerations for Tankfarm Layout:īelow considerations are to taken into account while designing a Tankfarm for Process plants: General considerations: Handles large capacity under high pressure.Ĭommonly used for drain collection of the plant at atmospheric pressure.Ĭommonly used for corrosive fluid at atmospheric pressure. Used to store products under high pressure. Products found in such tanks include Ammonia (-28 ☏), Propane (-43.7 ☏) and Methane (-258☏). Tanks stores liquefied gases at their boiling point. The roof of tank rises and lowers with the stored contents thereby reducing vapour loss & minimizing fire hazard. Used for countless products including Petroleum, Chemicals, Petrochemicals, Food products & Water Types of Tanks in Process plant depend on the product to be stored, potential for fire, and capacity to be handled. Cluster of tanks together in a same are termed as “ Tank Farms”. Storage tank are containers used for storage of fluids for the short or long term. The use of tanks is common in all kinds of plants found in oil & gas industry.
