Molecular sieve dehydration is a mature dehydration process and being applied widely at home and abroad presently,which has such advantages as simple operation,small land occupation,non-sensitivity to changes of feed gas temperature,pressure and flowrate. Water content in dehydrated gas may be as low as 10-6. Generally,molecular sieve dehydration process includes 2-tower flow,3-tower flow or multiple-tower flow. Summarized are some important operating parameters of molecular sieve dehydration unit,which may be for reference in future engineering design.
