A Det Norske Veritas Modeled Qualification Process for a Turbocompressor Incorporating a Rotary Separator Known as the Integrated Compression System

Abstract

The Det Norske Veritas (DNV) Technology Qualification Process requires several steps to be completed before new technology can be qualified for service based on proven experience. This paper will present a brief overview of the DNV Qualification Process and how it was applied by an original equipment manufacturer (OEM) during the development of a new product that incorporates a separator into a centrifugal compressor. The concept of incorporating a separator in the same casing as a centrifugal compressor is a novel approach that was not previously proven. The OEM created a demonstration rig to validate the concept of liquid separation and gas compression in a single case. The development process included the design of mechanical components based on previously existing rules, the creation of new design rules and analytical tools to accommodate new product specification and requirements, as well as analysis of the resulting designs. In addition, extensive experimental testing of the new designs allowed the calibration of the analytical tools and subsequent optimization of the components. This development and design process resulted in the creation of a virtual design/development/test laboratory. The economic and technical value of this virtual design and test process will also be discussed.
