“…Super-gravity technology refers to applied technology created by using scientific principles developed by studying the physical and chemical change processes in a supergravity environment [47][48][49][50][51], usually in gas-liquid and liquid-liquid contact and reaction processes [52][53][54]. Super-gravity technology began to be more widely used in the chemical industry in the 1980s and is a qualitative leap forward in enhancing mass transfer processes [55].…”

The long dissolution time and large dispensed volumes of oil repellent polymers in offshore oil fields lead to a great increase in the volume and number of dissolution and maturation tanks in the polymer formulation system. However, there is limited space and load-bearing capacity at the offshore platform and only a small space is available for the dispensing system. To further optimize the polymer dispensing system and reduce its floor space, the super-gravity technology may be considered as a way to speed up the dissolution of the polymer. The mechanism of super-gravity rapid dissolution was investigated by establishing mathematical models and with indoor experiments. The effects of filler pore size and super-gravity factor on polymer dissolution time and solution viscosity were investigated using the super-gravity rapid dissolution device, then combined with established graded forced stretching devices for field magnification experiments. The results indicated that the super-gravity method can substantially shorten the polymer dissolution time. The basic dissolution time of the polymer AP-P4 was shortened by 35 min compared with the conventional formulation method after use of the super-gravity rapid dissolution device. The optimal process conditions for the preparation of polymer solution by the super-gravity rapid dissolution device were selected as the optimal super-gravity factor range of 1031~1298.

Supergravity fields with high gravity acceleration can promote interphase ship velocity and convection velocity. Over the past decade, research has been devoted to enhancing electrochemical reactions by using supergravity fields. The enhancement of electrochemical reactions is ascribed to the acceleration of mass transfer and bubble separation. In this Minireview, the intensification kinetics of a supergravity field on mass transfer and bubble separation during electrochemical reactions are analyzed theoretically. The progress in terms the enhancement of electrochemical reactions (such as metal electrodeposition, water electrolysis, and chloralkali electrolysis) under a supergravity field is reviewed. The structures and properties of functional films electrodeposited under a supergravity field on both the cathode and the anode are summarized. The Minireview is helpful to understand the effect of the mechanism of the supergravity field on electrochemical reactions and to expand potential applications.
