This paper presents the methodology and results of a detailed energy analysis of the Texas Capitol Restoration. The purpose of this analysis was two-fold: 1) to determine the projected energy cost savings of a series of ...

A centrifugal compressor presenting rotating stall can exhibit many problems, as limitation on its operational range, high level of subsynchronous vibrations, reduced efficiency and premature bearing wear. There are many ...

The current centrifugal compressor design for the Oil & Gas market is more and more challenging since the cost requirements and the presence of many competitors is pushing towards casing size reduction and rotational speed ...

The task of the lighting designer has become very complex, involving thousands of choices for fixture types and hundreds of possible lamps. The designer who can consider the most combinations of these items guarantees each ...

Energy consumption due to air infiltration is customarily assumed to equal the mass flow rate times the specific enthalpy difference between the inside and outside air. Anderlind showed theoretically that this represents ...

This paper presents a detailed analysis and evaluation of impeller efficiency and overall compressor performance as they relate to specific impeller manufacturing methods, manufacturing tolerances, and quality control. The ...

The popularity of VFD motors in compressor trains has increased in recent years. Increased process flexibility is a primary consideration for implementation of VFD systems. However, this comes at a cost of increased ...
