Variable / Constant springs and spring sway braces. Purpose and definition
Oliver Piay, Karen When in a piping system is required a restriction that can withstand the load on a certain point, while allowing the movement of the pipe in the direction of application of force, a flexible support most be used. The most common flexibile supports used on the industry are the variable and constant…
Read MoreDry Gas Seals for compressors and Auxiliary Equipment, SMS and Shut-down safety systems
Holder, Norbert C. Typically, compressors with dry gas shaft seals are used in applications in which they are critical parts of the entire process. Every component of a dry gas seal is designed to manage exposure to extreme conditions. The seals can be arranged in single, double or tandem arrangements according to the application. A dry…
Read MoreReplacing a High-Speed Integrally Geared Pump with Pitot Tube Pump to Improve Plant Reliability
Maceyka, Tom For many years high-speed integrally geared pumps have been the centrifugal pump choice for low-flow high-head services in the refining, petrochemical and chemical industries. While many of these pumps operate satisfactorily, many users experience frequent failures when there is a rapid change in flow rate, also known as a “process upset.” A fully…
Read MoreNew ASME B31.3 2014 aspects like the new concepts about heat treatments or inspection
González Andrino, Ramón The last year, a new version of our Process Piping Code, ASME B31.3 -2014 was introduce. We will discuss the main changes and give an introduction to some of them. The main points to consider are the following: Category M Fluid service (and Chapter VIII), changes at table 304.1.1, 305.2.3 Pipe for…

Evolution of Gas Turbine Combustion Systems to DLE Extending Fuel Flexibility
De la Fuente Ortiz, Jesús Demand for higher gas turbine fuel flexibility with reliable combustion systems is becoming a decission making factor in several applications accross the power generation and Oil and Gas Industry when selecting turbomachinery. During this exciting workshop I will share the latest developments in dry low emission technology with non standard…
Read MoreVibration analysis as an important tool for the centrifugal compressors commissioning. Historical case: Oil-whirl and other defects
Ramírez, Rubén Commissioning and start-up is the final step before production runs in a processing plant. During this step, it’s usual that several problems take place in the machinery. Machinery start-up and adjustments in the process conditions cause vibrations in the units. Centrifugal compressors are especially sensitive machines during this process and very critical. Thus…
Read MoreThermosolar power plants: HTF pipes requiremens and supporting considerations
Rodríguez Fernández, Ángel Most of the types of Thermosolar power plants use a Heat Transfer Fluid (HTF) to transfer the solar thermal energy to a steam generator. The produced steam will be used directly in a steam turbine to produce electricity or used to increase the performance of a thermal power plant. The pipes and…
Read MoreEngineering procedures in Hazardous Atmospheres in Power Plants
Rubio Martínez, Ana Hazardous atmospheres are one of the non-visible components of a facility. Dealing with them in the right way is not easy because of their physical and chemical properties and the needed of knowledge about their extension and location in an early stage of the project. The presentation shows some deadlines and strategies…
Read MoreOil Free, Compact Compression Systems
Gilarranz, José Compact, oil-free compression systems have been around for quite some time but the benefits of the technology are usually not well understood. This technical paper is intended to provide a detailed discussion on the different technologies and options that are available from the OEM, and how they can be used as individual building…
