![]() ESDUpac A9242 provides the following design and performance prediction procedures. This opportunity to use waste energy is unique to Ejectors and makes a compelling business case with respect to OPEX and CAPEX, as no ‘new energy’ is required to run the Ejector. ESDU 92042 provides details of a computer program, ESDUpac A9242, for use in the design and performance evaluation of ejectors and jet pumps in which the working fluids are gases. For projects where existing high-pressure gas or liquids are readily available, the use of Ejector technology becomes a ‘no-brainer’ when compared with mechanical gas compression technologies. The ejector is one of the few compressors immune to liquid carryover in the suction gas. The design must incorporate the appropriate nozzle and diffuser compatible with the gas velocity. ![]() In many cases, they can utilise existing or ‘ waste’ gas or liquid streams to allow them to operate. Ejectors are used both as subsonic and supersonic devices. This simple design makes Ejectors very cost effective when compared to traditional compressors and well suited to ‘regions of conflict’ where equipment maintenance often requires expensive security considerations.Įjectors use a high pressure ‘motive’ stream to drive their operation. ![]() As such, they are ideally suited to Gas Compression as they have no moving parts, require zero maintenance and can be installed in the same way as regular pipework. Ejectors are static, pipework-based compressors. ![]()
