Abstract: Disclosed are systems and methods for treating contaminated material. The material is heated by nonconductive and nonconvective heating in a vacuum chamber such that the surface of the material is heated without significant heating of the air within the chamber. The surface of the material is heated to at least a volatilization temperature of the contaminants or to a decomposition temperature of one or more compounds in intimate contact with the contaminants, so that the concentration of contaminants in the material is reduced. Exhaust is removed from the chamber and cooled. A solids and/or liquids collector removes condensed solids and/or liquids and has a gas outlet connected to a vacuum pump.

Abstract: Hydroprocessing facilities may operate for extended periods of time before detection of mercury in the inlet facilities, as mercury adsorbs onto the metallic pipelines used to transport the hydrocarbon fluids, e.g., gas, produced waters, from the wells to processing facilities (“flowlines”). Once the pipelines become “saturated” with mercury, mercury will breakthrough and be detected at the inlet facilities. A mercury management/control scheme is disclosed wherein a thermal treatment step using any of laser treatment, a combustor, or an to induction coil is used to clean the pipeline, managing mercury accumulation in the pipeline for a reduced mercury concentration in the fluid exiting the flowlines.

Abstract translation: 在检测入口设施中的汞之前，加氢处理设备可能会长时间运行，因为汞吸附到用于将烃流体（例如，天然气，产水）从井运输到处理设施（“流线”）的金属管道上， 。 一旦管道用汞“饱和”，汞就会突破，并在入口设施被检测出来。 公开了一种汞管理/控制方案，其中使用激光处理，燃烧器或感应线圈中的任何一种的热处理步骤来清洁管道，管理管道中的汞积聚，以减少离开该流体的流体中的汞浓度 流线。
