Abstract
Abstract The instant disclosure is directed to a method for solidifying marine tanker hydrocarbon cargoes to prevent the escape of the hydrocarbon from damaged compartments. The formation of suitable gels contain the hydrocarbon and thus avoid pollution of the sea and nearby shores. Gelling agents are disclosed which permit gellation to occur at a controlled rate, making them particularly suitable for use aboard tankers.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
40 words
The method of claim 1 wherein the amount of gamma -butyrolactone used is from about 0.5 to about 2 weight percent, based on said hydrocarbon and the amount of cocoamine used is from about 0.75 to about 3 weight percent.
Claim 2
Independent Claim
74 words
A method for gelling hydrocarbon in marine cargo holds which comprises the following steps in combination; introducing into said oil from about 0.5 to about 2 weight percent, based on said oil, of gamma -butyrolactone and thereafter introducing in said oil from about 0.75 to about 3 weight percent of cocoamine whereby the reaction product of said gamma -butyrolactone and said cocoamine forms insitu in said oil and said reaction product gels said oil.
Claim 3
Independent Claim
33 words
A method for preventing the escape of a hydrocarbon from a ruptured storage vessel which comprises gelling said oil by forming the reaction product of gamma -butyrolactone and cocoamine insitu in said oil.
