Natural Gas Compressor FAQ
Q1: How does a natural gas compressor work?
Driven by an electric motor or an engine, the compressor transfers mechanical energy to its compression components to compress the natural gas, thereby reducing its volume and increasing its pressure. The resulting increase in density facilitates long-distance pipeline transport, storage, and subsequent processing or utilization.
Q2: What are the common malfunctions encountered during natural gas compressor operation?
Compressor malfunctions stem from various factors, primarily involving the following areas:
- Mechanical failures: These are the most common type, including bearing damage, seal failure, rotor or blade damage, and issues with shafts and couplings. These often manifest as abnormally high vibration, increased noise, or a sharp drop in efficiency.
- Lubrication system failures: Issues such as lubricant degradation, oil line blockages or leaks, and oil pump malfunctions can lead to accelerated equipment wear or even shaft seizure.
- Cooling system failures: Insufficient cooling water flow or reduced cooler efficiency can cause the equipment to overheat, compromising performance and safety.
- Vibration issues: Vibration is a persistent problem for compressors with complex root causes. It may stem from fluid dynamics (gas flow pulsation, surge), mechanical factors (rotor imbalance, poor foundation), or piping vibration. In one instance, a compressor operated with unresolved vibration issues for seven years.
Q3: Why is the sealing system so critical for natural gas compressors?
Natural gas is a flammable and explosive hazardous medium; any leakage can easily trigger a fire or even an explosion.
The compressor's shaft seal is a crucial component that prevents natural gas from leaking along the rotating shaft. For the dry gas seal systems commonly used in centrifugal compressors, it is essential to maintain proper seal gas pressure and flow rates and to use high-quality filters to prevent external impurities from entering the sealing assembly.
A painful lesson illustrates this: to address a vibration issue, a plant installed a substandard metal hose on the discharge pipeline. Twenty days later, the hose ruptured due to vibration fatigue, causing an instantaneous release of natural gas at 50 bar pressure. This triggered an explosion that shattered the factory's windows and blew off the roof.
