US 12,545,847 B2 · Natural gas system for processing and delivery

Abstract

A natural gas processing system is mounted on a mobile platform that is transported to a natural gas source, such as a well. The system supplies natural gas through multiple hose reels to operate multi-fuel engines for well field equipment such as pumps, compressors, and trucks. A coalescing filter removes contaminants from the natural gas. A generator powered by the natural gas supplies process electricity. A process control monitors and controls the natural gas processing system, including pressure, temperature, moisture, and flow sensors. A gas chromatograph will determine the chemical composition of the natural gas. A gas evacuation system removes gas from the hose reel assemblies in the event of an emergency. An emergency shutdown system will halt the process in the event of high liquid levels, a gas leak, fire, or gas composition out of specification.
