Expert lubricant selection needed

Specialty gas compressor lubricants work in direct contact with gas stream and may be diluted with gas or contaminated with some gaseous or liquid media. This would alter lubricant properties. For proper lubricant selection we need to perform calculations with gas dilution and contamination in mind.
