How to select a compressor for acetylene?

When selecting an acetylene compressor, consider the following factors: 1. Flow rate requirement: Calculate the actual flow rate based on the maximum flow velocity of 3 m/s in the acetylene pipelines within the plant and workshops, as well as the pipe dimensions. 2. Pressure requirement: Considering the operating pressure range of 0.007 MPa to 0.15 MPa, the compressor outlet pressure must meet the highest operating pressure along with a certain margin. 3. Compressor type: Acetylene is a highly flammable and explosive gas; therefore, a dedicated acetylene compressor with high safety standards must be used. 4. Material and structure: The material and structure of the compressor must be suitable for acetylene gas to prevent spontaneous ignition and corrosion. 5. Safety protection measures: Comprehensive safety protection measures are required, such as temperature alarms, pressure alarms, and explosion-proof devices. 6. Manufacturer: Choose a manufacturer with experience in producing acetylene compressors and a good reputation. The specific selection requires taking into account various factors such as the actual production process, gas consumption, and acetylene purity, with professional personnel carrying out the calculations and design. .

For selecting any compressor, it is necessary to know the inlet and outlet pressures; it is not possible to make a selection based only on the pressure within the pipes； The actual flow rate needs to be known; merely providing the maximum flow velocity is not sufficient to determine it – at least the inner diameter of the pipe must be given.
