摘要： A gravel pack assembly has a longitudinal body that disposes in a borehole. A wellscreen and other components can connect to the body to complete the assembly. One or more packoff seals or bushings disposed in the body's inner passage can engage a smooth external surface of a crossover tool when disposed therein to prevent passage of sand and fluids between the tool and the assembly's inner passage. The packoff seals or bushings can be fixed or activated by movement to engage the smooth external surface of the crossover tool.

摘要： A gravel pack assembly has a longitudinal body that disposes in a borehole. A wellscreen and other components can connect to the body to complete the assembly. One or more packoff seals or bushings disposed in the body's inner passage can engage a smooth external surface of a crossover tool when disposed therein. This sealing prevents passage of sand and fluids between the tool and the assembly's inner passage. Moreover, the smooth external surface makes the tool less likely of becoming stuck in the inner passage. The packoff seals or bushings can be fixed or activated by movement to engage the smooth external surface of the crossover tool.

摘要： A vapor condensor connected to a glycol reboiler to prevent emissions of aromatic compounds from glycol dehydration from escaping into the atmosphere. Steam and vaporized hydrocarbons are directed into the vapor condenser where they are sprayed with 80 degree or below Fahrenheit water. The water spray cools the steam and vaporized hydrocarbons so that a substantial portion of the vapors are changed to a liquid phase which is collected in an accumulator located below the vapor condenser. A water jacket surrounding a central cylinder of the vapor condenser tends to keep the condensed vapors in the liquid phase. The remaining vaporized hydrocarbons which are not condensed are drawn out of the accumulator and burned in a burner connected to the glycol reboiler. The steam and vaporized hydrocarbons in the glycol reboiler have an initial temperature in range of 350 to 400 degrees Fahrenheit.
摘要翻译：连接到二醇再沸器的蒸汽冷凝器，以防止芳族化合物从乙二醇脱水中排放逸出到大气中。蒸汽和蒸发的碳氢化合物被引导到蒸汽冷凝器中，在那里喷洒80度或更低于华氏水。水喷雾冷却蒸汽和蒸发的碳氢化合物，使得大部分蒸气变成液相，其被收集在位于蒸气冷凝器下方的蓄液器中。围绕蒸气冷凝器的中心圆筒的水套倾向于将冷凝的蒸汽保持在液相中。未冷凝的剩余的蒸发的碳氢化合物从蓄能器中抽出并在连接到二醇再沸器的燃烧器中燃烧。乙二醇重沸器中的蒸汽和汽化烃的初始温度范围为350至400华氏度。
