Elliott Introduces High-Speed Multi-Valve Steam Turbine Optimizing efficiency and reliability Features & Benefits Elliott’s new high-speed, high-efficiency multivalve steam turbine combines the reliability of an impulse style turbine with the efficiency of a reaction style turbine to provide outstanding performance in a range of refinery services. Designed to meet API 612 standards, the new turbine has a small footprint but packs a powerful punch, offering a technical leap forward in speed and efficiency. At typical pressure and temperature* operating conditions, the turbine’s efficiency is greater than 80%. Direct drive – eliminates the need for a separate gear box The turbine’s high-speed condensing design eliminates the need for a separate gear box which greatly reduces the amount of mineral oil, cooling water, and steam required for high-efficiency operation. The new 13-stage, multi-valve model serves as a direct driver for compressors in oil and gas-related services including hydrocracking, hydrotreating, catalytic reforming, alkylation, refrigeration, gas boosting and coking. The turbine’s high speed capabilities allow for smaller compressor frame sizes with fewer stages for a smaller overall footprint. Elliott’s new high-speed turbine is also available in a back pressure design with fewer stages. High performance – greater than 80% efficiency Operational efficiency – 12-14% steam savings Turbine will speed match the compressor allows for smaller compressor frame size with reduced number of stages Compact casing size – 20% in space savings Lower costs – less mineral oil and cooling water required Reduced maintenance – fewer spare parts required * Typical operating conditions: 600 psig / 750°F. High pressure / high temperature operating conditions: 1300 psig / 905° F

Continuous Operating Conditions Max Inlet Pressure: Condensing / Back Pressure For optimum efficiency, the turbine was designed to accommodate 100% steam admission using a five-valve, bar lift configuration. The steam chest can accommodate multiple nozzle ring base diameters to optimize flow path efficiency. Other features include adjustable end packing, a machined bearing housing with common threading, and a 30-inch condensing exhaust. Design Highlights The aeropath for the new turbine was designed to optimize efficiency and reliability. Ease of maintenance Improved rotor dynamics Titanium...
