Abstract:

To develop a reliable vacuum system for sea water desalting systems, a variety of sizes and combinations of water-operated air ejectors were tested. Results showed that the three air ejectors tested produced the same closed suction vacuum, that only the staged system improved operation, and that there was no optimum com bination. The 2-12-in. air and water ejectors were selected for further testing. The results of these tests indicate that the air ejector appears suitable for operation of desalting equipment. Cost of equipment, operation, and maintenance is attractive compared to that for present vacuum systems. Further investigation of ejectors is planned. Author
