Abstract
An aqueous based metalworking fluid that is environmentally friendly and process for metalworking with the fluid. The metalworking fluid is sampled at periodic intervals and replenished to predetermined operating specifications with the aqueous based metalworking fluid without the need for individual boosters.
Claims20
A fluid composition for drilling or metalworking in a manufacturing operation, comprising:
- a predetermined amount of severely hydrotreated naphthenic oil;
- a predetermined amount of monoethanolamine;
- a predetermined amount of monoisopropanolamine;
- a predetermined amount of polyoxyethylene alkyl ether phosphate;
- a predetermined amount of tall oil fatty acid;
- a predetermined amount of calcium acetate;
- a predetermined amount of water;
- and
- compounds of predetermined amounts selected from the group consisting of a water hardener, polymer foam controller, viscosity enhancer, rheological, viscosity reducer, defoamer, lubricant, dispersant, and/or combinations thereof;
- wherein a mixture of the predetermined amounts and structure of the constituents is operable for providing a metalworking and/or drilling fluid that is soluble in water, and, has higher tramped oil release, defoams in high turbulence environments, and/or tolerates high insurgencies of high hardness content of water to remain water soluble under predetermined conditions.

A fluid composition for drilling and/or metalworking in a manufacturing operation, comprising:
- a predetermined amount of severely hydrotreated naphthenic oil;
- a predetermined amount of monoethanolamine;
- a predetermined amount of monoisopropanolamine;
- a predetermined amount of water;
- and
- predetermined respective amounts of a plurality of constituents selected from the group consisting of vegetable oil and esters, petroleum sulfonic acid sodium salt, succinic acid anhydride sodium salt, sulfated castor oil, tall oil fatty acid, C23 fatty alcohol, fatty alcohol ethoxylate, ethoxylated cyclohexlamine, polyoxyethylene alkyl ether phosphate, tolytriazole sodium salt, modified siloxane polymer, calcium acetate, polyoxyethylene alkyl ether carboxylate, stearate amine, vinyl diol and/or combinations thereof;
- wherein the fluid composition is completely soluble in water, has higher tramped oil release, defoams in high turbulence environments, and tolerates high insurgencies of high hardness content of water to remain water soluble under predetermined conditions;
- and
- wherein the fluid requires no separate boosters for restoring any desired predetermined properties to the fluid composition.

A method for preserving the life of a metalworking fluid in a manufacturing operation comprising:
- providing a manufacturing operation including a cutting fluid reservoir for supplying cutting fluid to the manufacturing operation;
- filling the cutting fluid reservoir with a high lubricity semi-synthetic water based fluid composition comprising:
- an operable amount of severely hydrotreated naphthenic oil;
- an operable amount of monoethanolamine;
- an operable amount of monoisopropanolamine;
- an operable amount of water;
- an operable amount of at least one of a predetermined water hardener, ester phosphorous, polymer foam controller, viscosity booster, rheology, viscosity reducer, rheology, defoamer, lubricity, dispersant, and/or combinations thereof;
- operating the manufacturing operation for a predetermined period of time using the metalworking fluid;
- sampling the metalworking fluid after a predetermined time to determine the concentration of the fluid composition;
- determining an operable amount of fluid composition for restoring concentration to a predetermined desired level;
- adding the fluid composition to the reservoir for restoring original concentration and properties to the metalworking fluid mixture;
- and
- running the manufacturing operation for a predetermined period of time.
