A method for recovering hydrocarbon trapped in a hydrate formation,
comprising the steps of (a) contacting the hydrate formation with an
aqueous solution comprising from 10% to 75% by weight of a salt such as
potassium formate or acetate salt to liberate hydrocarbon from the
hydrate formation and producing a mixture of hydrocarbon and water
vapour; (b) transporting the hydrocarbon/water vapour mixture and the
aqueous solution to a separator, whereby the said aqueous solution
absorbs water vapour from the mixture during the transportation step, to
form a more dilute aqueous solution of the alkali metal salt, thereby
inhibiting formation of hydrocarbon hydrates; (c) separating hydrocarbon
from said dilute aqueous solution; (d) regenerating the aqueous solution
of step (a) by heating said dilute aqueous solution to remove absorbed
water vapour; and (f) recycling the regenerated aqueous solution to step
(a).
