ABSTRACT:
Seawater which is to be used as injection water in underground oil reservoirs to obtain a higher degree of hydrocarbon recovery deoxygenated by a new and improved process that eliminates the consumption of stripping gas and at the same time attains the highest possible degree of oxygen removal without polluting the water. Seawater is circulated through an inert gas, thus removing oxygen. Degassed water is separated from the inert gas, and the latter is routed through a zone for purification and regeneration. Hydrogen is introduced into the gas containing oxygen, and this gas mixture subsequently flows through a catalytic reactor where hydrogen and oxygen are reacted to form water, whereafter the purified gas is recirculated.
