Reducing Space in Offshore applications for Centrifugal compressors

Banchi, Nicola High Pressure Ratio Compressor (HPRC), it is a new type of compressor architecture that aims to increase the compression station compactness by reducing the number of compressor bodies, in particular for offshore markets provides a great benefits reducing weight, minimizing footprint and installation time. GE’s HPRC technology is based on an innovative architecture…

Nozzle Design, the weak point in every Pressure Vessel

Tirenti, Javier To attach a nozzle in a pressure vessel, it is necessary to make a hole in the shell or head body in question. When making this hole, an area of the vessel is being “taken away”, therefore stress paths are going to divert tangentially to the hole. Thus, we must “substitute” the removed…

Thermoplastic labyrinth seals to reduce leakage in centrifugal compressors

Metz, Kolja Thermoplastic labyrinth seals offer the possibility to reduce the internal leakage flow over the cover disc of closed impellers in centrifugal compressors. The efficiency gain compared to traditional metallic labyrinth seals mainly depends on differential pressure and sealing clearance. The presentation shows the results of development and testing of thermoplastic labyrinth seals, which…

Turbocharger vs. HPRT: energy recovery applications in Oil&Gas Industry

Teijeiro, Beatriz In the past, most of the Oil&Gas industries used conventional pressure reducing valves to suit to downstream process conditions. Therefore, a big amount of hydraulic energy was dissipated and wasted. Hydraulic Power Recovery Turbines (HPRT) were developed in order to convert this pressure into mechanical shaft energy and increase the overall process efficiency…

Introduction to thermosolar power plants and piping design issues

Rodríguez Fernández, Ángel Oil crisis in the late 70s forced to investigate and develop new renewable technologies, between them the thermosolar power plants were developed. In the late 90s several companies started to investigate again with that technology and in the first decade of this century, this technology has been developed and a great number…

Increase your process efficiency and flexibility @ low CAPEX

Bellentani, Vittorio In the Oil&Gas industry many processes require centrifugal pumps and compressors to supply variable values of pressure and flow rate; this can be achieved with various advantages through speed regulation, which is feasible through different driver concepts, briefly compared in the present work. Special focus is set on hydrodynamics combined with fixed speed…

Multistage Pumps for light hydrocarbons – How to ensure you get the best pump for the service

Bradshaw, Simon With the growth of fracking, light hydrocarbons (SG < 0.7) became a preferred feedstock in chemical processes. Many services require high pressures from multistage pumps. These have specific design and application challenges that are unique to this service. Addressing these is critical to achieving good pump reliability. This seminar addresses the following challenges:…

Piping Systems susceptible to vibration: AIV / FIV

García-Lozano, Javier Different excitation mechanisms can cause piping vibration; the induced fatigue could have catastrophic consequences and finally lead to the failure of the system. In addition to some sources of vibration historically considered (reciprocating pumps and compressors, 2 phase flow…), nowadays is becoming more demanded the study of the AIV (Acoustically Induced Vibration) and…
