    摘要: A system and method of safely discharging hydraulic fluid from a compressed gas cylinder, comprises filling first and second compressed gas cylinders with compressed gas. A compressed gas dispensing system has a pump that pumps hydraulic oil into the compressed gas cylinders to maintain a desired pressure while gas is dispensed. Gas is dispensed from the first cylinder while hydraulic fluid is pumped into the cylinder to maintain the desired pressure. Once the first cylinder is depleted, the hydraulic oil is discharged from the first cylinder. The process is repeated for the second cylinder. However, the hydraulic oil must be discharged from the second cylinder before the substantial depletion of the gas. To safely discharge the hydraulic oil, compressed gas from the second cylinder is distributed into the first cylinder. Once the second cylinder has reached a safe discharge pressure or volume, the hydraulic fluid is discharged.
