Title:
PROCESS AND PLANT FOR DISTILLATION OF AIR
Document Type and Number:
Japanese Patent JPH07280432
Kind Code:
A
Abstract:
PURPOSE: To obtain a process and a plant for distillation of air in which the capacity of cooling tower is enhanced.
CONSTITUTION: To regenerate the absorbent which serves to purify compressed air from water and carbon dioxide, there is used residual gas from an air distillation apparatus 10, heated to a substantially constant moderate regeneration temperature between the temperature of the air entering the mass of absorbent and a temperature which is at most about 50°C higher, preferably about 10-20°C higher, than this entering air temperature. This gas is then sent to a water refrigeration tower 16 for cooling the compressed air.
