For the existing system, Vacuum condensers are integral components of a vacuum system and are critical to the proper performance of a vacuum distillation tower. Within a vacuum system IPS-E-PR-745 "Process Design of Vacuum Equipment (Vacuum Pumps and Steam Ejectors)". 4.2.2 Mechanical Design of steam ejectors shall be in accordance with "Standards for Steam Jet Ejectors" published by the Heat Exchange Institute. 4.2.3 All motive steam piping shall be designed in accordance with ASME power piping B31.1. 4.3 Capacity Steam Ejector Psv Set Pressure - posted in Relief Devices Forum: Hi I currently have a PSV on a steam ejector suction chamber which has a set pressure above the test pressure. Design Pressure = 15 PSIG Test Pressure = 22.5 PSIG PSV set pressure = 25 PSIG The PSV is protecting the suction chamber of the ejector.
