Fluid Disposal

Drilling Fluid Disposal Conversion into Cements 

Important parameters to characterize the properties of a drilling mud are specific weight, viscosity, gel strength, and filtration performance. 

Viscosity is measured by means of a Marsh funnel. The funnel is dimensioned so that the outflow time of 1 qt (926 ml) freshwater at 21° C (70° F) is 26 s. 

Viscosity also is measured with a rotational viscometer. The mud is placed between two concentric cylinders. One cylinder rotates with constant velocity. The other cylinder is connected with a spring. The torque on this cylinder results in a deviation of the position from rest, which may serve as a measure of viscosity. 

Gel strength is obtained with the rotational viscometer when the maximal deflection of the pointer is monitored when the motor is turned on with low speed, the liquid being at rest for a prolonged time before, for example, for 10 minutes. This maximal deflection is referred to as a 10-minute gel.

In severe cases, paralysis may also affect the upper limbs. Recovery is usually slow and is not always complete. Tri-ort/20-cresyl phosphate (TOCP), an isomer found in tricresyl phosphate, was the first organophosphate ester linked to OPIDN, being responsible for an epidemic of paralysis in the southeastern United States that led to the name "ginger jake paralysis" (Smith 1930) (see Section 2.4). Current manufacturing processes for organophosphate ester hydraulic fluids are designed to minimize production of this isomer, although it is possible that fluids disposed of in the past may be contaminated. 

Mineral Oil Hydraulic Fluids. Disposal of used mineral oil hydraulic fluids is regulated as used oil under the Solid Waste Disposal Act as amended by the Resource Conservation and Recovery Act (RCRA) and as amended by the Used Oil Recycling Act (42 U.S.C. 6901, 6905, 6935, 6937-6939, and 6074, see 40 CFR parts 260, 261, 266, 271, and 279). Used mineral oil hydraulic fluids to be recycled are not listed as hazardous wastes and can be burned for energy recovery or recycled. In general, the newer mineral oil hydraulic fluids (including water-in-oil emulsion fluids) do not contain known chemicals or other materials that are listed in 40 CFR 261 (RCRA) and can be burned for energy recovery or recycled. However, this may not apply to some of the older hydraulic fluids, particularly those containing PCBs.

The use of S.S.T. Sump Saver Tablets results in a significant savings in time and money because fluid life can be greatly extended. Not only does this save the cost of replacement fluid but also provides significant savings in terms of less machine downtime and lower cost of spent fluid disposal. Additionally, a cleaner fluid means improved machine productivity and extended tool life.
