Abstract

The present invention provides an integrated geared compressor having a combination of centrifugal and positive displacement compression stages, comprising a gear system configured to be driven by a drive unit, a plurality of compression stages coupled to the gear system, wherein the plurality of compression The stages include at least one centrifugal compression stage and at least one positive displacement compression stage. Additionally, associated methods are provided.

Description

[0001] This application claims the U.S. Provisional Application entitled "Integrally Geared Compressor Having a Combination of Centrifugal and Positive Displacement Compression Stages," filed April 11, 2016 Priority and Benefit of No. 62 / 321,016. technical field [0002] The following relates to integrated geared compressors, and more particularly to integrated geared compressors having centrifugal compressor stages and positive displacement compressor stages. Background technique [0003] There are various types of compressors, each with advantages and disadvantages in operating conditions. For example, centrifugal compressors efficiently and reliably manage large volumes of cold gas, while positive displacement compressors can be used to manage high pressure ratios and small volumes of gas. For example, with the development of liquefied natural gas (LNG) systems, higher pressures are required to supply gas to the main drive. While the supply side of the system is cryogen...
