  • Patent number: 9938799
    Abstract: A method includes designing a subsea equipment assembly having an insulation covering an outer surface of at least one equipment unit and a flow path formed through the at least one equipment unit. The designing includes modeling a temperature profile of the subsea equipment assembly having a fluid within the flow path, identifying at least one hot zone along an interface between the insulation and the outer surface, where the at least one hot zone is exposed to temperatures above a degradation temperature of the insulation, and designing at least one cold zone along the interface to border the at least one hot zone, the at least one cold zone exposed to maximum temperatures below the degradation temperature of the insulation.

  • Patent number: 8562935
    Abstract: The present invention is directed towards methods (processes) of providing large quantities of carbon nanotubes (CNTs) of defined diameter and chirality (i.e., precise populations). In such processes, CNT seeds of a pre-selected diameter and chirality are grown to many (e.g., hundreds) times their original length. This is optionally followed by cycling some of the newly grown material back as seed material for regrowth. Thus, the present invention provides for the large-scale production of precise populations of CNTs, the precise composition of such populations capable of being optimized for a particular application (e.g., hydrogen storage). The present invention is also directed to complexes of CNTs and transition metal catalyst precurors, such complexes typically being formed en route to forming CNT seeds.
