Variation of temperature, pressure, and flow rate as a function time. (a) Variation of pressure, gas temperature and sample temperature in the reaction vessel as a function time for the system without ethanol. (b) Accumulated volume of gas released from hydrate dissociation in the system with 2 ml ethanol added, but not direct contact with ice powder, as a function of time in the dissociation stage. (c) Accumulated volume of gas released from hydrate dissociation in the system without additive (ethanol) as a function of time in the dissociation stage. Green dashed-dotted line, the sample temperature; brown dashed line, the gas temperature in the reaction vessel; and black solid line, the pressure in the reaction vessel; red line and blue line, accumulated volume of gas released from hydrate dissociation in system, respectively, without and with ethanol added.
