    • Methods and systems are provided for obtaining information related to a customer service location and directions for routing a service technician from one customer service location to another. One embodiment includes requesting at least one set of coordinates associated with the customer service location; accessing a technician server to direct a global satellite positioning system to obtain the set of coordinates for the customer service location; obtaining the coordinates and updating one or more databases with said coordinates. The coordinates may include at least one of a latitude and a longitude associated with the customer service location. Another embodiment includes obtaining through a technician server at least one set of “from” coordinates associated with the first customer service location and at least one set of “to” coordinates associated with the second customer location; transmitting the “from” and “to” coordinates to a mapping system; and, generating directions in the mapping system based on the “to” and “from” coordinates. At least one of the sets of coordinates includes latitude and longitude data. System and computer-readable media embodiments of these methods are also provided.

    • A method for extracting oil from oil-contaminated soil containing 2 to 5 wt. % oil, comprising contacting the oil-contaminated soil with a solvent in the presence of sonic energy in the frequency range of 0.5 to 2.0 kHz. Specifically, a solvent is first mixed with the oil-contaminated soil and the mixture is then formed into a slurry of oil-contaminated soil particles suspended in the solvent. Thereafter the oil-contaminated soil slurry is passed through a shaker screen to remove soil particles greater than 1/4 inch. The oil-contaminated soil slurry containing the smaller soil particles is then fed into the top of a vertically disposed, substantially rectangular shaped, hollow acoustic chamber of uniform cross-section. Fresh solvent is injected into the bottom of the acoustic chamber that flows upwardly through the acoustic chamber. The fresh solvent is injected at a rate low enough whereby the oil-contaminated soil particles fall by gravity through the upwardly flowing solvent. The oil-contaminated soil particles and solvent in the acoustic chamber are subjected to acoustic energy in the frequency range of 0.5 to 2.0 kHz displaces the oil from the oil-contaminated soil particles that is dissolved by the upwardly flowing solvent without cavitation of the solvent. The substantially oil-free soil particles containing only 0.2 to 0.4 wt. % oil are recovered from the bottom of the acoustic chamber and spread over the land for land farming. The present method may also be used for extracting oil from oily sludge or oil-based drill cuttings.
    • 一种从油污土壤中提取油的方法,含有2〜5wt。 包括使油污染的土壤与溶剂在0.5至2.0kHz的频率范围内的声能的存在下接触。 具体地说,首先将溶剂与油污染的土壤混合,然后将混合物形成悬浮在溶剂中的油污染土壤颗粒的浆液。 此后,油污染的泥浆通过振动筛以除去大于+ E,1/4 + EE英寸的土壤颗粒。 然后将含有较小土壤颗粒的油污染土壤浆料进料到具有均匀横截面的垂直布置的,基本矩形的中空声学室的顶部。 将新鲜溶剂注入到通过声室向上流动的声室的底部。 以足够低的速度注入新鲜溶剂,由此油污染的土壤颗粒通过重力通过向上流动的溶剂而下落。 在声学室中的油污染的土壤颗粒和溶剂在0.5至2.0kHz的频率范围内经受声能,使来自被向上流动的溶剂溶解的油污染的土壤颗粒的油置换而不会溶剂溶剂。 基本上无油的土壤颗粒仅含有0.2至0.4wt。 %的油从声学室的底部回收,并在土地上传播用于土地耕作。 本方法也可用于从油性污泥或油基钻屑中提取油。
