    摘要： The present invention is based on the following:(1) that when tar sand is conditioned and diluted in the hot water extraction process, there are two classes of anionic surfactants (originating from carboxylate and sulfonate groups) present in the process water;(2) that each of these surfactants has the potential to dominantly influence the maximizing of primary froth production by the process;(3) that it is possible for a particular extraction circuit to determine the critical free surfactant concentration in the process water at which primary froth extraction is maximized for each of the two classes of surfactant;(4) and that it is possible to determine which of the two classes of surfactant will first (that is, at lowest NaOH addition) dominate the process when a particular tar sand feed is being processed.The present invention therefore involves:determining the critical free surfactant concentrations ("C.sub.cs.sup.O " and "C.sub.ss.sup.O ") for the circuit for each of the carboxylate and sulfonate classes of surfactants;monitoring the free surfactant concentrations ("C.sub.cs " and "C.sub.ss ") in the process water for an ore being processed;determining which of C.sub.cs.sup.O and C.sub.SS.sup.O occurs at a lower NaOH addition;and then adjusting NaOH addition to the extraction process to bring the first dominating surfactant concentration toward the critical concentration value.

    摘要翻译： 本发明基于以下几点：（1）当焦油砂在热水提取过程中进行调理和稀释时，存在于工艺水中的两类阴离子表面活性剂（来自羧酸盐和磺酸盐基团）; （2）这些表面活性剂中的每一种都有可能主导地影响通过该方法使初级泡沫产生的最大化; （3）特定提取电路可以确定在两种类型的表面活性剂中的主要泡沫提取最大化的工艺水中的临界游离表面活性剂浓度; （4），并且可以确定当处理特定的焦油砂进料时，两种表面活性剂中的哪一种将首先（即在最低的NaOH添加）中占主导地位。 因此，本发明涉及：确定表面活性剂各羧酸盐和磺酸盐类的电路的临界游离表面活性剂浓度（“CcsO”和“CssO”）; 监测处理矿石的工艺用水中的游离表面活性剂浓度（“Ccs”和“Css”）; 确定CcsO和CSSO中的哪一个在较低的NaOH添加下发生; 然后调节NaOH添加到萃取过程中，使第一主要表面活性剂浓度达到临界浓度值。

    摘要： A method and an apparatus for determining the interfacial or surface tension, static or dynamic, between two liquids or between a gas and a liquid under conditions of varying temperature and pressure; and a method for adjusting the interfacial or surface tension in a petroleum reservoir for enhanced oil recovery. A tensiometer is provided which is capable of measuring interfacial or surface tension under pressure and temperature conditions which simulate those present in an actual petroleum reservoir. Measuring the interfacial and surface tension values under actual reservoir conditions then enables the selection of surfactants and other materials for adjusting the interfacial and surface tension to desired values for optimizing the enhanced oil recovery from that reservoir. A tensiometer is provided which includes a calibration body which is imaged along with the image of the test droplet in the tensiometer chamber. This imaging of both the calibration body and the test droplet provides the capability of correction of distortions in the image due to the nature of the chamber window for high pressure and/or high temperature measurements. The tensiometer is also provided with a surface against which the test droplet is imaged and measured, which is an annealed ionomer polymer coating on a polymer surface.

    摘要： The hot water process is sensitive to the nature of the tar sand feed, which varies. An alkaline process aid, usually NaOH, is normally added to the conditioning step of the process and is needed to obtain good bitumen recovery from most tar sand feeds. The invention is based on the discovery that, for a particular extraction circuit used, there is a single value of free surfactant content in the aqueous phase of the process slurry which will yield maximum primary froth recovery regardless of the type of tar sand feed used. The process in accordance with the invention therefore comprises: (a) determining, for a single tar sand type and the extraction circuit used, the free surfactant content in the aqueous phase of the slurry, which will yield the maximum primary bitumen forth recovery; (b) monitoring the free surfactant content in the aqueous phase of the slurry during subsequent processing of various types of tar sand feed in said circuit; and (c) varying the process aid addition to the slurry as the nature of the tar sand feed varies, to maintain said free surfactant content substantially at the level which leads to maximum primary bitumen froth recovery.
