1Productivity

If hydraulic gas compressors are used in oil and gas field environments, then gas compression function is provided, but contamination of hydraulic fluid from natural gas components occurs

Engineering Contradiction:

Improvegas compression functionVSAvoidhydraulic fluid contamination

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The hydraulic cylinder is divided into two separate chambers: a first chamber containing hydraulic fluid and a second chamber containing natural gas, separated by a piston. This segmentation prevents direct contact between the hydraulic fluid and natural gas components, eliminating contamination while maintaining compression functionality.

Inventive Principle:

Solution Approach 2:

The piston acts as an intermediary element between the hydraulic fluid chamber and the natural gas chamber. It transmits the driving force from the hydraulic fluid to compress the natural gas without allowing the two fluids to mix, thus preventing contamination.

AI summary

Methods and systems are provided to adaptively control a hydraulic fluid supply to supply a driving fluid for applying a driving force on a piston in a gas compressor, the driving force being cyclically reversed between a first direction and a second direction to cause the piston to reciprocate in strokes. During a first stroke of the piston, a speed of the piston, a temperature of the driving fluid, and a load pressure applied to the piston is monitored. Reversal of the driving force after the first stroke is controlled based on the speed, load pressure, and temperature.
