Experimental study of gas production from hydrate dissociation with continuous injection mode using a three-dimensional quiescent reactor

► Hydrate exploitation is simulated with continuous injection mode using a 3-D reactor. ► An optimal water temperature and injection rate exists for gas production of hydrate. ► Compared with Na2SO4 and EG, injecting NaCl solution has the highest gas production. ► The continuous injection mode is more in favor of gas production of hydrate.
