چکیده

Abstract Flue gas flooding is one of the important technologies to improve oil recovery and achieve greenhouse storage. In order study multicomponent flue storage capacity enhanced (EOR) performance water-alternating (flue gas–WAG) injection after continuous waterflooding in an reservoir, a long core system was built. The experimental results showed that factor gas–WAG increased by 21.25% could further enhance reduce water cut significantly. A novel material balance model based on mechanism developed estimate each component reservoir oil, as free post-waterflooding reservoir. ultimate ratio 16% process. calculation mainly consists N 2 CO , only exists phase cores, other components are dissolved water. Finally, strategies from three perspectives for storage, EOR, combination EOR were proposed, respectively.

Flue Gas Cooling

When waste heat is not utilized, cooling of flue gases in special cooling chambers becomes necessary, if the dust':'collecting and associated equipment is constructed of metal. The two most common methods of cooling are by dilution with ambient air, and by evaporation of water in the gas stream. Usually, they are combined. Load sharing depends largely on acceptable visibility of stack effluvia ...

Flue gas desulfurization

Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators. The most common types of FGD contact the flue gases with an alkaline sorbent such as lime or limestone. As sulfur dioxide is responsibl...

Flue gas treatment for CO2 capture

This report is in two sections: the first describes the flue gas and its treatment in post-combustion capture and the second covers the flue gas in oxyfuel combustion capture. The main components of the flue gas in pulverised coal combustion for postcombustion capture are CO2, N2, O2 and H2O, and air pollutants such as SOx, NOx, particulates, HCl, HF, mercury as well as other contaminants. The ...
