Understanding Gas Booster Pumps

Gas booster pumps are used to increase the pressure of gases in various systems. They are vital in industries such as manufacturing, petrochemicals, and medical gas supply. These pumps work by compressing gas from a lower pressure to a higher pressure, making them ideal for applications requiring a consistent and reliable gas flow.

Pre-Installation Preparations

Before installing a gas booster pump, it is crucial to undertake several preparatory steps:

1. Read the Manual: Thoroughly read the manufacturer's manual to understand the specific requirements and features of your gas booster pump.
2. Site Assessment: Ensure the installation site is suitable, with adequate space, ventilation, and structural support.
3. Safety Checks: Verify that all safety standards and regulations are met, including checking for potential hazards.

Installation Process

Positioning the Pump

Select a location that allows easy access for maintenance and is close to the gas source. The area should be free from moisture, dust, and extreme temperatures.

Connecting the Pump

1. Gas Inlet and Outlet Connections: Connect the gas inlet to the source and the outlet to the system using appropriate fittings. Ensure all connections are tight to prevent leaks.
2. Power Supply: Connect the pump to a reliable power source, following the electrical specifications provided by the manufacturer.

Testing the Installation

Once connected, perform a series of tests to ensure the system is functioning correctly:

1. Leak Testing: Use a leak detector to check all connections for gas leaks.
2. Operational Test: Run the pump and observe its performance, ensuring it reaches the desired pressure without issues.

Using the Gas Booster Pump

Starting the Pump

To start the gas booster pump, follow these steps:

1. Check Connections: Ensure all connections are secure and there are no visible signs of damage or wear.
2. Power On: Turn on the power supply and gradually increase the pump's speed to the desired level.

Monitoring and Maintenance

Regular monitoring and maintenance are crucial for the efficient operation of your gas booster pump:

1. Routine Inspections: Regularly inspect the pump for any signs of wear or damage.
2. Filter Changes: Replace filters as recommended by the manufacturer to prevent blockages.
3. Lubrication: Ensure moving parts are properly lubricated to reduce friction and wear.

Troubleshooting Common Issues

Understanding common problems and their solutions can help maintain your gas booster pump:

1. Low Pressure Output: Check for leaks or blockages in the system and ensure the pump is operating at the correct speed.
2. Overheating: Verify that the pump is not operating beyond its capacity and that the cooling system is functioning correctly.
3. Unusual Noises: Inspect for loose parts or debris in the system and ensure the pump is properly lubricated.

Safety Considerations

Safety should always be a priority when using gas booster pumps:

1. Protective Gear: Always wear appropriate protective gear, such as gloves and safety glasses, when operating or maintaining the pump.
2. Emergency Procedures: Be familiar with emergency shut-off procedures and have a plan in place for handling gas leaks or other emergencies.

Conclusion

The answers to the following questions will provide the parameters for the selection of any gas booster or ProPak booster system.

1. What is the maximum pressure to be attained?

You need to know the pressure that the system will have to reach, either now or sometime in the future. This does not need to be the usual working pressure, but the maximum pressure ever needed.

2. What is the required flow rate?

You need to know the required flow rate at the required discharge pressure. This is not the flow rate at the maximum pressure, but the flow rate at the working pressure. Remember that every booster has a maximum pressure where it will stall and produce no flow, but at any pressure less than that it will produce flow. This flow reduces in quantity as the output pressure approaches the stall pressure.

3. Is the flow rate constant?

Do you have a process application where you need a constant flow at a constant pressure? If so, then this is expressed as “x” SCFM (NM3) @ “y” PSIG (Barg).

4. Is the flow rate decreasing?

Do you have an application where you are filling cylinders or some other vessel from a lower supply pressure to a higher storage pressure. To select the proper booster or booster system, you need to know the size of the vessel to be filled. This can be supplied in any form that can be converted to ACF.

5. What is the required fill time for the vessel?

It is very common to have an initial fill times that is unrealistic. Many people who are not
familiar with gases ask for fill times that will require uneconomic systems. Therefore it is important to think about the longest possible fill time the application can stand.

6. What is the gas supply pressure?

The performance of any gas booster is a function of the incoming gas pressure. Simply stated: “any gas booster will only discharge the amount of gas it takes in”. The higher the inlet gas pressure, the more SCF of gas are squeezed into the gas section and
therefore the more gas discharged. Gas supply can have more than one source. Therefore it can have many combinations of flow, pressure and temperature.

7. What is the drive pressure?

This is not the initial pressure in the system first thing in the morning before all of the uses of air are operational, but rather should be the minimum that the plant experiences throughout the day. The booster may have to provide maximum performance when the drive conditions are at their worst.

8. What is the gas?

Some gases cannot be pumped with standard boosters. They may require special seals, materials of construction, venting and other considerations. This is also important when higher pressures are required in filling applications to determine the compressibility of the gas. Applications involving gas boosters will always fall into one of four categories. It is very important to clearly determine into which category a particular application fits.

a) The supply pressure is at a constant pressure (Ps) and the discharge gas is at a constant flow (Q) and pressure (Po).

b) The supply gas is from a decreasing pressure and the discharge gas is at a constant flow and pressure. It is safe to assume that the supply flow rate will decrease as the supply pressure decreases. To maintain the constant outlet flow the booster will have to increase its cycle rate.

c) The supply gas is at a constant flow and pressure and the discharge gas it at an increasing 8 pressure.. It is safe to assume that the discharge flow rate will decrease as the discharge
pressure Increases.

d) The supply gas is at a decreasing pressure and the discharge gas is at an increasing pressure. It is safe to assume that the flow rate will decrease significantly as the pressures get further apart.
