摘要： A process for in situ recovery of a tar sand deposit located beneath the earth's surface. A number of boreholes are drilled laterally from subsurface tunnels into the lower portion of the tar sands formation. Initially as a displacing means such as steam is injected into the boreholes, the tar sands become viscous and gravity flow into the bottom of the boreholes. Continuing to apply steam removes the tar sand deposits located in interstitial crevices between the boreholes thereby allowing the steam to flow laterally through these interstitial crevices to nearby boreholes. The steam rises toward the upper portion of the resource formation to create a horizontal heated plane of steam to further remove tar sand deposits located therein.
摘要翻译：用于原位回收位于地球表面下方的焦油砂沉积物的方法。许多钻孔从地下隧道横向钻进焦油砂层的下部。最初，当诸如蒸汽的置换装置注入到钻孔中时，焦油砂变得粘稠，重力流入钻孔的底部。继续施加蒸汽会消除位于钻孔之间的间隙缝隙中的焦油砂沉积物，从而允许蒸汽横向流过这些间隙缝到附近的钻孔。蒸汽向资源地层的上部上升，形成水平的蒸汽平面，以进一步除去位于其中的焦油砂沉积物。

摘要： An oil furnace black process wherein a stream of liquid water intersects a liquid stream of feedstock hydrocarbon after streams of both liquids have been injected into a heated carbon black furnace. When the water stream contacts the liquid feedstock stream it is relatively cold in comparison to the temperature of the feedstock. Exothermic reaction of the feedstock with free oxygen present in the furnace is caused by contact with the water, and is characterized by a visible blazing and a substantial increase in temperature beyond the point at which the feedstock and the water are mixed. In the present invention the injection of water into the furnace thus serves a new and different purpose, i.e., in prior processes water has been injected to quench the temperature of a carbon black aerosol within the furnace or beyond it, and the water has thus been injected after formation of the carbon black had been at least substantially completed. In the present case water is injected into the feedstock hydrocarbon at a very early stage after it enters the furnace and instead of a quenching, the injection of water causes a flaming reaction of the feedstock with oxygen and thus promotes the formation of carbon black. The resulting carbon black products are characterized by an elevated iodine adsorption and/or an unusually high electrical conductivity.
摘要翻译：一种油炉黑色方法，其中在两种液体流已经注入加热的炭黑炉中之后，液态水流与原料烃的液体流相交。当水流接触液体原料流时，与原料的温度相比，它相对较冷。原料与炉中存在的游离氧的放热反应是与水接触引起的，其特征在于可见的燃烧和温度的显着升高超过原料和水混合的点。在本发明中，将水注入炉中起因此起着新的和不同的目的，即在以前的方法中，已经注入了水以淬灭炉内或其外的炭黑气溶胶的温度，因此水已被在形成炭黑后注入至少基本上完成。在这种情况下，水在进入炉子后的非常早的阶段将水注入原料烃中，而不是骤冷，注入水会导致原料与氧的燃烧反应，从而促进炭黑的形成。所得到的炭黑产物的特征在于碘吸附升高和/或异常高的导电性。
