  • Review on enhanced oil recovery by nanofluids

    Li, Kewen   Wang, Dan   Jiang, Shanshan  

    The addition of nanoparticles into water based fluids (nanofluid) with or without other chemicals to Enhance Oil Recovery (EOR) has recently received intensive interest. Many papers have been published in this area and several EOR mechanisms have been proposed. The main EOR mechanisms include wettability alteration, reduction in InterFacial surface Tension (IFT), increase in the viscosity of aqueous solution, decrease in oil viscosity, and log-jamming. Some of these mechanisms may be associated with the change in disjoining pressure because of the addition of the nanoparticles. The experimental data and results reported by different researchers, however, are not all consistent and some even conflict with others. Many papers published in recent years have been reviewed and the associated experimental data have been analyzed in this paper in order to clarify the mechanisms of EOR by nanofluids. Wettability alteration may be one of the most accepted mechanisms for nanofluid EOR while reduction in IFT and other mechanisms have not been fully proven. The main reason for the inconsistency among the experimental data might be lack of control experiments in which the effect of nanoparticles on oil recovery would be singled out.

  • Heparin depolymerization by immobilized heparinase: A review

    Indu Bhushan   Alhumaidi Alabbas   Jyothi C. Sistla   Rashmi Saraswat   Umesh R. Desai   Ram B. Gupta  

    Abstract Heparin is a member of the glycosaminoglycan (GAG) family composed of glucosamine and uronic acid units containing O-sulfo, N-acetyl and N-sulfo groups, which are alternating in the chain and linked by 1→4 manner. It is a naturally occurring anticoagulant that prevents the formation of clots and their growth within blood. Certain low molecular weight heparins (LMWHs) are considered as better therapeutic agents than natural heparin because of the reduced side effects and smaller risk of bleeding. LMWHs can be produced from heparin by chemical or enzymatic depolymerizations. Heparinases catalyze the cleavage of glycosidic linkage between amino sugars and uronic acids in heparin. There are three kinds of heparinases which are frequently used for depolymerization of heparin. Despite wide range of applications of heparinases in health care, their use still has been hampered due to poor stability and high cost. To overcome this problem heparinases are recommended for immobilization to reduce the cost of product and enhance stability. Heparinases have been successfully immobilized using various methods and supports, mostly for deheparinization of blood through extracorporeal devices. The focus of this review is to present the current status of heparinase immobilization including various supports and methods used, stability and applications.
