Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
52 words
A method for disposing of a waste liquor comprising the steps of: neutralizing said liquor by adjusting the pH to about 6-9; mixing said neutralized liquor with an amine; and mixing said neutralized liquor/amine mixture with a fuel oil/fatty acid mixture thereby creating a water and oil emulsion; and incinerating said emulsion.
Claim 2
Independent Claim
52 words
A method for disposing of a waste liquor comprising the steps of: neutralizing said liquor by adjusting the pH to about 6-9; mixing said neutralized liquor with an amine; and mixing said neutralized liquor/amine mixture with a fuel oil/fatty acid mixture thereby creating a water and oil emulsion; and incinerating said emulsion.
Claim 3
Dependent Claim
41 words
The method of claim 1 wherein said amine, fatty acid, and neutralized liquor are mixed in the following porportions based upon a total of 100 parts by weight (pbw): amine 10-30 pbw, fatty acid 30-75 pbw, and neutralized liquor 10-60 pbw.
Claim 4
Dependent Claim
30 words
The method of claim 2 wherein the amount of fuel oil is about 0.5-4 times the sum of the weights of the neutralized liquor, amine, and fatty acid (50-400 pbw).
Claim 5
Dependent Claim
30 words
The method of claim 2 wherein the amount of fuel oil is about 0.5-4 times the sum of the weights of the neutralized liquor, amine, and fatty acid (50-400 pbw).
Claim 6
Dependent Claim
25 words
The method of claim 1 wherein said waste liquor is acidic and said pH is adjusted by the addition of an amine to said liquor.
Claim 7
Dependent Claim
24 words
The method of claim 1 wherein said waste liquor is acidic and said pH is adjusted by the addition of ammonia to said liquor.
Claim 8
Dependent Claim
32 words
The method of claim 1 wherein said amine mixed with said neutralized liquor is selected from the group consisting of dimethylamine, trimethylamine, monoethanolamine, diethanolamine, triethanolamine, dimethylethanolamine, 2-amino-2-methyl-1-propanol, 2-amino-1-butanol, monoethylamine, diethylamine, and, triethylamine.
Claim 9
Dependent Claim
15 words
The method of claim 1 wherein said amine mixed with said neutralized liquor is monomethylamine.
Claim 10
Dependent Claim
39 words
The method of claim 1 wherein said fatty acid in said fuel oil/fatty acid mixture is selected from the group consisting of saturated and unsaturated fatty acid having between 12 and 24 carbon atoms (C 12 -C 24 ).
Claim 11
Dependent Claim
20 words
The method of claim 9 wherein said fatty acid in said fuel oil/fatty acid mixture is tall oil fatty acid.
Claim 12
Dependent Claim
18 words
The method of claim 1 wherein said fuel oil in said fuel oil/fatty acid mixture is diesel fuel.
Claim 13
Dependent Claim
22 words
The method of claim 1 wherein the same amine is used to adjust said pH and to mix with said neutralized liquor.
Claim 14
Dependent Claim
17 words
The method of claim 1 wherein the liquor is the byproduct from the production of dimethylopropionic acid.
Claim 15
Independent Claim
113 words
A method for disposing of an acidic waste liquor comprising the steps of: neutralizing said liquor by adding ammonia, monomethylamine, or an amine selected from the group consisting of dimethylamine, trimethylamine, monoethanolamine, diethanolamine, triethanolamine, dimethylethanolamine, 2-amino-2-methyl-1-propanol, 2-amino-1-butanol, monoethylamine, diethylamine, and, triethylamine to adjust the pH to about 6-9; mixing said neutralized liquor with monomethylamine or an amine selected from the group consisting of dimethylamine, trimethylamine, monoethanolamine, diethanolamine, triethanolamine, dimethylethanolamine, 2-amino-2-methyl-1-propanol, 2-amino-1-butanol, monoethylamine, diethylamine, and, triethylamine; and mixing said neutralized liquor/amine mixture with a fuel oil/saturated and unsaturated fatty acid having between 12 and 24 carbon atoms (C 12 -C 24 ) mixture thereby creating a water and oil emulsion; and incinerating said emulsion.
Claim 16
Independent Claim
113 words
A method for disposing of an acidic waste liquor comprising the steps of: neutralizing said liquor by adding ammonia, monomethylamine, or an amine selected from the group consisting of dimethylamine, trimethylamine, monoethanolamine, diethanolamine, triethanolamine, dimethylethanolamine, 2-amino-2-methyl-1-propanol, 2-amino-1-butanol, monoethylamine, diethylamine, and, triethylamine to adjust the pH to about 6-9; mixing said neutralized liquor with monomethylamine or an amine selected from the group consisting of dimethylamine, trimethylamine, monoethanolamine, diethanolamine, triethanolamine, dimethylethanolamine, 2-amino-2-methyl-1-propanol, 2-amino-1-butanol, monoethylamine, diethylamine, and, triethylamine; and mixing said neutralized liquor/amine mixture with a fuel oil/saturated and unsaturated fatty acid having between 12 and 24 carbon atoms (C 12 -C 24 ) mixture thereby creating a water and oil emulsion; and incinerating said emulsion.
Claim 17
Dependent Claim
41 words
The method of claim 14 wherein said amine, fatty acid, and neutralized liquor are mixed in the following porportions based upon a total of 100 parts by weight (bpw): amine 10-30 pbw, fatty acid 30-75 pbw, and neutralized liquor 10-60 pbw.
Claim 18
Dependent Claim
30 words
The method of claim 14 wherein the amount of fuel oil is about 0.5-4 times the sum of the weights of the neutralized liquor, amine, and fatty acid (50-400 pbw).
