ANOMALIES IN GAS BLENDING



DUE TO THE MECHANISM OF COMPRESSION O2 PERCENTAGE
VALUE AT COMPRESSOR OUTPUT WILL BE SLIGHTLY LOWER
THAN INPUT PERCENTAGE
EXAMPLE:- A SETTING OF 36.5% ON THE OXYTRONIC WILL
PRODUCE AN OUTPUT O2% OF APPROXIMATELY 36%
THIS DIFFERENCE WILL VARY WITH DIFFERENT COMPRESSORS
AND IS REPEATABLE ONCE ESTABLISHED
OPERATING
PROCEDURES
ANOMALIES IN GAS BLENDING

DUE TO RELATIVE HUMIDITY, THE ACTUAL ATMOSPHERIC O2
PERCENTAGE MAY NOT BE 20.9%
