摘要： An improved tree stabilization system with a perimeter anchor system of a plurality of individual ground anchor assemblies configured adjacent to the tree or shrub to be supported and a related stabilization method. The tree stabilization system is particularly well suited for use in securing mature trees and stands of trees. As it is adjustable, it may be used for long term stability rather than simply during initial root development. The tree stabilization system includes a retention system that is attached to the perimeter anchor system and runs over the root system and pins the root system to the ground at certain important locations. The ground anchor assemblies are inserted into the ground so that the top end to which the retention system is attached is at or under ground level. The tree stabilization system may include a configuration for anchoring an entire stand of trees and may include a feature for adjusting the tension of the retention system to allow the appropriate amount of downward pressure as conditions change.

摘要： A method is provided for treating the effluent from a hydrocarbon pyrolysis unit processing heavier than naphtha feeds to recover heat and remove tar therefrom. The method comprises passing the gaseous effluent to at least one primary transfer line heat exchanger, thereby cooling the gaseous effluent and generating superheated steam. Thereafter, the gaseous effluent is passed through at least one secondary transfer line heat exchanger having a heat exchange surface with a liquid coating on said surface, thereby further cooling the remainder of the gaseous effluent to a temperature at which tar, formed by the pyrolysis process, condenses. The condensed tar is then removed from the gaseous effluent in at least one knock-out drum. An apparatus for carrying out the method is also provided.
