Every successful installation starts with a good foundation
July 16 2013 -
Every installation needs an adequate foundation. For pumps, there are three basic classes of equipment that require different styles of foundations. An excellent source for further information is Process Industry Practices (PIP) document REIE686 which is a joint document with API which titles it RP686. PIP has a supplemental document REIE686A that has additional information.
An isothermal compressor is an old dream of the engineer, based on the value of lower specific power consumption (per unit mass) compared with regular (adiabatic) compressors. This technology could improve the efficiency of gas turbines and related plants. And it can save power in many compression jobs in process plants, especially in cases of high pressure ratio.
The misalignment of turbomachine train rotors is the second most common malfunction of turbomachineries (the first most common malfunction is unbalance). Turbomachine alignment procedures have been involving quite sophisticated laser-optic instrumentations.
Technical notes on gas turbine starting device, starting, reference check, component life, inspection, sizing and speed range selection are discussed. The main concerns are gas turbine arrangement and operation solution to obtain optimum fuel consumption, low emission and reasonable reliability.
Here's a summary of a paper presented by Steve Ingistov, PE, BP/WCC and Mustapha Chaker of Bechtel Corporation about the Watson Cogeneration Company (WCC) plant at the ASME/IGTI conference in 2011. The plant was fully commissioned during the first part of 1988, consists of four GE 7EA gas turbines, two Dresser-Rand Steam Turbines and four dualpressure heat recovery steam generators.
Turbomachine design and arrangement is often complex and optimization must be made between the mechanical requirements, electrical specification, auxiliary equipment design, operation, reliability, commercial and maintenance.
