Air fed to air separation units such as cryogenic distillation columns needs to be prepurified; that is, the concentration levels of air-borne impurities such as water vapor, CO2, and light hydrocarbons need to be brought down below the tolerable limits which are in the ppm or sub-ppm levels.

Generally the dietary intakes of investigated metals Fe, Mn, Zn, Cu, Ni, Cd and Pb, from vegetables grown in contaminated areas R and M were above the dietary intakes of metals from reference area, and below the tolerable limits, with some exceptions (Table 5).
The estimated soil loss rate is above the tolerable limit of 10 t ha−1 y−1.
The inverter remains connected, and the voltage is lowered within the tolerable limit.
But at frequency of 9 GHz, certain distortion appears in the pattern within the tolerable limit.
About 21.25% of the watershed area experienced soil losses above the tolerable limit of 11 t ha−1 year−1.
The drug treatment appeared to be within the tolerable limit.
Also, the tolerable limits varied greatly depending on the test temperature.
They help technicians calculate the appropriate angle of launch, the shape of the nose cone of the rocket, the tolerable limits of weather and other factors.
