Solar powered air compressor configured to manage multiple streams of instrument gas

Abstract

A system for generation of compressed gas for use by a pneumatic device positioned off-grid or at a wellsite. The system includes primary, secondary, and optionally tertiary supplies of gas, primary and secondary power supplies, flow lines connecting an output from each of the gas supplies, and an output line connectable to the pneumatic system. The primary air supply may be compressed air at a desired pressure, such as generated by an air compressor utilizing solar and/or wind power or utility power. If there is insufficient air pressure from the primary supply, a secondary and then a tertiary supply of gas can be utilized as backup. The secondary supply can be bottled gas or the field gas currently in use at the remote or wellsite. In some instances, the secondary supply may be bottled gas, and a tertiary supply may be wellsite field gas. The secondary power supply may be a generator as a backup to the solar and wind power supply.
