What are Gas Boosters?

Gas boosters are devices used in various industrial processes and equipment to increase the pressure of gas. They work by compressing the gas, thereby increasing its delivery rate. Gas Boosters can be powered by an electric motor, hydraulics, low or high pressure air, or a lever system.

The pressure of the inlet gas in a gas booster typically ranges from 50 to 125 psig, but it can be higher or lower depending on the application. The booster’s motor speed and compressor size determine how much downstream flow is delivered. This means that boosters can be customized for the particular gas compression requirements of an industry.

Gas boosters are crucial for industries that depend on natural gas, as consistent gas pressure is essential for trouble-free operation and consistent quality. They are also used to boost the pressure of air in high-rise buildings. Even though natural gas is a renewable and affordable fuel, many industrial and commercial applications require higher pressures than the standard service. A natural gas boost system will improve the pressure level of gas in an area and reduce the need for gas cylinders.

What are the Types of Gas Boosters?

Gas boosters come in three primary configurations, each employing a distinct power source for compression:

• Pneumatic-Driven Gas Boosters: These boosters rely on compressed air as the external power source. They utilize a piston or diaphragm design, where compressed air acts on one side of the piston/diaphragm, compressing the gas on the other side. Pneumatic boosters are known for their portability, ease of use, and lack of electrical components, making them suitable for hazardous environments. Additionally, they are relatively quiet compared to other types. However, their pressure output capabilities are typically lower compared to hydraulic or electric alternatives.

• Hydraulically-Driven Gas Boosters: These boosters utilize hydraulic fluid as the external power source. A hydraulic pump pressurizes the fluid, which then acts on a piston or diaphragm to compress the gas. Hydraulic boosters offer significantly higher pressure outputs compared to pneumatic ones, making them suitable for applications requiring very high-pressure gases. They are also well-suited for continuous operation due to their robust design. However, hydraulic boosters tend to be larger and heavier than pneumatic models, and they may require additional equipment like heat exchangers to manage heat generation during operation.

• Electrically-Driven Gas Boosters: These boosters use electric motors as the external power source. The motor drives a compressor mechanism, which compresses the gas. Electrically driven boosters offer several advantages, including the potential for precise control over pressure output and ease of integration with automation systems. They can also achieve high pressure outputs depending on the motor’s capacity. However, they are typically the most complex and expensive option among the three types.

Understanding Gas Booster Systems: What are the Key Components?

A gas booster system is more than just the booster itself. It’s a network of interconnected parts working together to safely and efficiently manage gas flow and pressure. Here’s a closer look at the essential components of a gas booster system:

• Pumps:  These act as the initial pressure source for the booster. They elevate the gas pressure to a level that allows the booster to function effectively. Gas booster pumps can be driven by various power sources depending on the application. Compressed air, hydraulic fluid, or electric motors are commonly used to drive these pumps.
• Valves:  These components act as checkpoints within the system, controlling the flow of gas. They perform various tasks like starting, stopping, and regulating the gas flow to and from the booster. Precise valve operation is crucial for ensuring the system functions properly and maintains safety standards.
• Pressure Regulators:  These are responsible for maintaining a constant pressure output, even if the input pressure fluctuates. This is particularly important in applications where a specific and unwavering gas pressure is critical for the process. Pressure regulators achieve this by adjusting an internal valve based on the incoming pressure, ensuring a consistent output pressure.
• Safety Relief Valves:  These valves prioritize safety by serving as a built-in pressure release mechanism. In case of system malfunctions or pressure surges, they automatically release excess pressure. This prevents potential damage to equipment and safeguards personnel from hazards associated with uncontrolled pressure buildup.

Choosing the Right System: Tailoring Components to Specific Needs

Selecting the most suitable gas booster system requires careful consideration of several factors:

• Gas Type: The type of gas being used in the system can influence component selection. Different gases may have varying compatibility requirements with specific materials used in pumps, valves, and other components.
• Desired Output Pressure: The target pressure you aim to achieve with the boosted gas is a crucial factor. The system’s components, especially the booster itself, need to be rated for the desired output pressure to ensure safe and efficient operation.
• Required Flow Rate: The volume of gas that needs to be processed per unit time (flow rate) is another critical aspect. The system’s components, particularly the pump and booster, must be capable of handling the required flow rate to maintain efficient gas delivery.
• Portability: Depending on the application, portability might be a significant factor. If the system needs to be moved frequently, its weight, size, and overall ease of transport become important considerations.
• Operational Environment: The surrounding environment where the system will be used can influence component selection. Factors like temperature extremes, exposure to moisture or dust, or the presence of flammable materials might necessitate specific material choices or additional protective measures for the system’s components.
• Desired Level of Automation: The level of automation needed for the system’s operation plays a role as well. If complete automation is desired, valves, pressure regulators, and even the booster itself might require integration with electronic controls and monitoring systems.

Understanding Pumps

A pump is an industrial device that moves or transfers fluids, such as liquids and slurries. Though there are many types of pumps, at their core, they all work by creating various pressures to drive fluids from one point to another. This is why pumps have become indispensable to many industries and even for personal use.

How does it work? This type of equipment converts mechanical energy into pressure or hydraulic energy to transfer liquid or slurries. In detail, pumps work by pushing air out of the way through the device’s moving parts. Hence, a vacuum-like storage space is created that can be filled with fluids.

Some common types of pumps are centrifugal pumps, which use a rotating impeller; diaphragm pumps, which use a rubber-made diaphragm to move corrosive liquids; and piston pumps, which use a piston to create that reciprocating motion.

Moreover, pumps find applications across a variety of industrial and commercial businesses. They are used in water treatment plants to distribute clean water. Piston pumps are also used in the Oil and Gas sector for hydrostatic testing and to transport crude oil and other fluids. Even industries that handle sensitive and viscous materials, like pharma and food, use pumps in their daily operations.

Understanding Gas Boosters

Unlike pumps that handle liquids, a gas booster compresses air, Nitrogen, and other gases. This mechanical equipment is primarily used in industries dependent on consistent high-pressure gas delivery. 

A gas booster system compresses low-pressure gas using mechanical means to achieve and release an effectual high-pressure output. Usually, gas boosters have a piston or diaphragm mechanism, which is the central part of the system and efficiently orchestrates the compression within a cylinder. 

⁤While both pumps and gas boosters aim to increase pressure, they differ significantly in function and design. ⁤⁤As previously mentioned, pumps are designed to move incompressible fluids like water, oil, and slurries. Meanwhile, gas boosters are mainly used to handle and compress gases. This means the latter focuses more on compression than moving the matter at hand. 

⁤Gas boosters are widely used in different sectors, like Aerospace, where they use equipment to pressurise hydraulic systems and fuel tanks. In the medical field, some equipment, like oxygen tanks, heavily relies on gas boosters to deliver high-pressure medical gases. In the Oil & Gas industry, gas boosters are used in gas testing equipment for proof and leak testing. Gas boosters are also essential in the manufacturing plants, present in some of the tools and equipment.

Key Differences Between Pumps and Gas Boosters

When choosing the right equipment for your specific personal or business needs, it is essential to understand the differences between your options. Since you are here trying to discover more about pumps and gas boosters, below is information containing the critical differences between the two. 

• Operational Mechanisms: To determine the device’s suitability for your application, you must understand how pumps and gas boosters operate. As mentioned earlier, pumps use impellers, diaphragms, or pistons to create pressure and move fluids. Meanwhile, a gas booster–using either a piston or diaphragm mechanism–aims to increase pressure and compress gases rather than moving them from point A to B. 
• Flow and Pressure Capabilities: If you need equipment that handles high flow rates with moderate pressure increases and is suitable for moving large volumes of fluids, then a pump is what you should look for. But if the focus is on significantly increasing gas pressure with lower flow rates, then a gas booster is what you need. The latter is ideal for applications needing high-pressure gas delivery. 
• Materials and Construction: Pumps and gas boosters are designed and engineered according to their applications. Pumps are manufactured depending on the fluid they will pump and its corrosiveness; common materials used are stainless steel, cast iron, or plastic.
