here we introduce a simple method to test the purity of C2H2 gas on site, we dip the silver nitrate solution onto the test paper, then put the test paper under the gas sampler, if the test paper colour doesn't change, the purity of C2H2 gas can reach at least about 98%, this purity is enough to be used in industrial application.

the acetylene gas is compressed by the piston compressor, which is piped to the molecular sieve high pressure dryer, the dryer can remove the moisture, then the dry acetylene gas is piped to the cylinder for filling

acetylene gas generator is an important equipment during the acetylene gas producting, the calcium carbide and water will react in the generator, and then the acetyhlene gas will be piped to the next equipment.

The function of this equipment is based on the principle of natural balance of adjacent adsorbent loads. In the drying stage, the adsorbent adsorbs water from the gas with high pressure flowing through the GZ-120/25 Molecular sieve high pressure acetylene gas dryer manual adsorber. During regeneration, a small amount of depressurized dry gas is replayed and regenerated through the adsorbent adsorbing water. Use the adsorption released by the gas in the drying process to heat the regeneration gas with reduced temperature after decompression, so as to improve the regeneration effect and reduce the regeneration consumption.

a set of 20m3/h acetylene gas plant are being loaded into 2 peices of 40 containers for customer in Republic of Paraguay in South Amierica
