Abstract: A mounting system for an industrial compression system including a first component close-coupled to a second component includes a first support for the first component. The first support is configured to resist movement of the first component in a first direction substantially horizontal relative to the first component, a second direction substantially vertical relative to the first component, and an axial direction relative to the first component. The mounting system also includes a second support for the second component. The second support is configured to resist movement of the second component in a first direction substantially horizontal relative to the second component and a second direction substantially vertical relative to the second component, wherein the second support permits movement of the second component in an axial direction relative to the second component.

Abstract: Methods for retrofitting a turbomachine are provided. A first trip cup of the turbomachine may be replaced with a second trip cup. The first trip cup may include a throw-out arm connected to a first trip cup spring. The second trip cup may include a plunger disposed in a hole defined by the second trip cup and a plunger spring encircling the plunger in the hole. The first trip cup may be removed from the turbomachine and the second trip cup installed such that a location of the plunger in the turbomachine is the same as a location of the throw-out arm in the turbomachine when the first trip cup was installed on the turbomachine. The tension in the plunger spring may be adjusted such that, when a speed of the turbomachine exceeds a predetermined value, the plunger actuates a trip paddle located adjacent the second trip cup.

Abstract: A method for operating a compressed air energy storage system is provided. The method can include compressing a process gas with a compressor train to produce a compressed process gas and storing the compressed process gas in a compressed gas storage unit. The method can also include extracting the compressed process gas from the compressed gas storage unit to an expansion assembly through a feed line. A valve assembly fluidly coupled to the feed line can be actuated to control a mass flow of the compressed process gas from the compressed gas storage unit to the expansion assembly. The method can further include heating the compressed process gas in a preheater fluidly coupled to the feed line upstream from the expansion assembly, and generating a power output with the expansion assembly.
