What is a necessary design requirement for compression equipment used with CNG?

The necessary design requirement for compression equipment used with Compressed Natural Gas (CNG) is that it must be designed for specific pressures and temperatures. This is crucial because CNG is stored and transported at very high pressures, typically around 3,000 to 3,600 psi. The compression equipment must be built to safely handle these pressures, as well as the temperature variations that may occur during operation. Ensuring that the equipment is engineered for the specific conditions of CNG use promotes safety, efficiency, and reliability in the compression and delivery processes.

While other factors such as noise levels, humidity resistance, and portability may be relevant in certain contexts, they do not hold the same level of critical importance as the requirement for the equipment to handle specific pressures and temperatures safely.
