Abstract
A METHOD FOR INHIBITING THE FORMATION OF CLATHRATE HYDRATES IN A FLUID HAVING HYDRATE FORMING CONSTITUENTS IS DISCLOSED. MORE SPECIFICALLY, THE METHOD CAN BE USED IN TREATING A PETROLEUM FLUID STREAM SUCH AS NATURAL GAS CONVEYED IN A PIPE TO INHIBIT THE FORMATION OF A HYDRATE RESTRICTION IN THE PIPE. THE HYDRATE INHIBITOR USED FOR PRACTICING THE METHOD IS SELECTED FROM THE FAMILY OF SUBSTANTIALLY WATER SOLUBLE COPOLYMERS FORMED FROM N-METHYL-N-VINYLACETAMIDE (VIMA) AND ONE OF THREE COMONOMERS, VINYLPYRROLIDONE (VP), VINYLPIPERIDONE (VPIP), OR VINYLCAPROLACTAM (VCAP). VIMA/VCAP IS THE PREFERRED COPOLYMER. THESE COPOLYMERS MAY BE USED ALONE OR IN COMBINATION WITH EACH OTHER OR OTHER HYDRATE INHIBITORS. PREFERABLY, A SOLVENT, SUCH AS WATER, BRINE, ALCOHOL, OR MIXTURES THEREOF, IS USED TO PRODUCE AN INHIBITOR SOLUTION OR MIXTURE TO FACILITATE TREATMENT OF THE PETROLEUM FLUID STREAM.
