ABSTRACT:
Lime, preferably as calcium oxide, is mixed with the contents of sumps, such as oil well sumps, and these generally have a pasty or plastic consistency. The calcium oxide reacts with the materials present and also dehydrates the contents of the sump, causing the sump contents to stiffen. This mixing is performed by a drag line scoop that carries calcium oxide through the sump contents, mixing and blending the oxide and contents as it moves because of the unique construction of the mixing scoop. Once the mixing and blending is complete and reaction of the calcium oxide and the contents is complete, the sump contents are dredged and deposited on high ground to dry by the combined action of sun and air. Drying periods may range from several days to several weeks and the material thereupon becomes a dry, hard and stable type of soil suitable for fill purposes and which, when neutralized with acid, also may be suitable for agricultural purposes.
