The Compressed Gas Association (CGA) announced the release of a new publication recently, titled CGA G-1.9, Recommended Practices for Maintaining the Proper Solvent Level in Acetylene Cylinders.

The publication covers recommendations for maintaining the proper solvent level in acetylene cylinders and provides fillers with a reliable method with which they can develop standard operating procedures.

Numerous tables enable operators to maintain the correct solvent level in a cylinder, without performing calculations each time a cylinder is checked.

“G 1.9 will lead to a greater understanding of the acetylene cylinder solvent system, the solventing process, increased safety, and increased efficiencies,” stated Jack Wert, Technical Manager for the CGA.

The Recommended Practices for Maintaining the Proper Solvent Level in Acetylene Cylinders is primarily intended for acetylene cylinder fillers. While the background, precautions, and general procedures given apply to all solvents in use with acetylene, special emphasis is given to the use of acetone and dimethylformamide (DMF).
