Within most plants there is often a desire to extend the time between outages. Several factors determine this but one to consider is the bearings ability to run for the extended time. This Tutorial will address common ...

This tutorial discusses the design and function of surge control systems, or more precisely, surge avoidance systems on the basis of the behavior of centrifugal compressors when they interact with compression systems. ...

The power and efficiency characteristics of a gas turbine are the result of a complex interaction of different turbo machines and a combustion system. In this tutorial, we will address the basic characteristics of each ...

API 682 is the leading document for mechanical seals in petrochemical, chemical, and pipeline services worldwide. It has combined the aspects of seal design, testing, standardization, and applications to provide the users ...

Centrifugal compressors are subject to transient events, such as emergency shutdowns, which can cause energetic surge events during rapid shutdown transients. Many modeling tools are used to predict the behavior of compressor ...

The development and design of control systems for centrifugal and axial compressors is discussed and explanations given to bring together features of control systems on varying machine designs. Potential problems resulting ...

Oil and Gas industry end users have generally approached the topic of centrifugal compressor performance estimation with little consideration to the effect of process gas conditions. This is customary since end users depend ...

The rising demand for oil and gas has led us to exploit oil fields and gas reservoirs with increasing amounts of contaminants. Reserves of natural gas are abundant, but about 40% of the fields contain high concentrations ...
