FIELD: process engineering.
SUBSTANCE: invention relates to has hydrate production plant and device of gravity dehydration. Device of gravity dehydration comprises cylindrical first column, cylindrical dehydration part arranged in first column top side; wager receiving part arranged on outer side of dehydration part, and cylindrical second column located on dehydration part top side. Note here that cross section area of second column increase continuously or intermittently from the bottom upward.
EFFECT: reduced resistance to gas hydrate motion at gravity dehydration, improved dehydration of gas hydrate suspension.
