| Abstract: | The default of burn-out electric heating tubes of the newly-installed electric heater used for the molecular sieve purification system of 6500m 3/h air separation unit is described.The default is eliminated by adding more gas baffles after causes of the default being analyzed.Through the retrofit the technical requirements for regeneration of the molecular sieve purifiers have been met.Furthermore,the electric heaters (one in operation,one stand-by)have been realized. |
