Demonstration of Capability of Low-Cost Calcium Carbonate to Restore Ph Levels of Sea for Protection of Marine Animals Post Oil Spills Due to Ship Grounding / Accidents as Part of Salvage Operations

Abstract: When a sea going vessel is grounded, the most dangerous effect of MARPOL is due to spillage of this fuel/oil which is discharged into the sea in enormous quantities and may also contain other acidic impurities. The effects of oil spillage include damage to marine life such as fishes, corals and sea shells. The ph of sea water generally varies between 8 to 9 and the same is regarded as congenial for biological existence of certain forms of marine life. Oil spills from ships containing fuels/oils cause acidification of sea water and result in lowering of ph of the affected area of sea water thereby causing death to marine life. Used CO2 absorbent which is chemically high-grade Calcium Carbonate in granular form (size <5 mm) can be used to neutralize and restore the ph of sea water contaminated through oil spill. The same was experimentally verified.
