REE assessment improves compressor performance


M


ost operators in the process gas industry are satisfied with their reciprocating compressors – but


feel they could do better. Are reliability and energy efficiency high enough? What about environmental soundness? How should they select the latest technologies to improve performance? The new REE Assessment process answers


this need. It gives clear, accurate data on the real performance of the compressor in terms of Reliability, Energy efficiency and Environmental soundness – REE. Senior compressor experts from


HOERBIGER carry out a REE audit on site to build up a picture of each compressor’s design, operating conditions, maintenance and failure records. The customer then receives a detailed report showing the performance of their compressors, with a REE index ranking equipment in terms of its potential for improvement and savings. A REE Assessment is a quick, accurate and


objective way to pinpoint good and bad actors and choose which compressors to modernize first. The next step is a detailed engineering study in combination with return-on-investment calculations to support an upgrade or revamp. Available worldwide for any reciprocating


compressor, the new REE Assessment helps operators choose the right technology and make the right business decisions. The result is a gain for the whole plant in term of reliability, efficiency and environmental performance Hoerbiger is a leader in of compression


technology, automation technology, and drive technology, covering: key components and services for compressors and gas- powered engines; piezo technology, hydraulic components and systems, valve automation and multi-market applications. ■

Quality control of materials


of routine inspection tasks in metallography, earth science, forensic investigation, and materials quality control and research. It offers users state-of-the-art universal white-light LED illumination with high-quality Leica optics. The ultra-bright, high-power LED


A


illumination provides users with a constant color temperature of 4500 K for brightfield, darkfield, interference contrast, and polarised light methods. In addition, users can visualise improved


surface inspection details with built-in oblique illumination technology. Real colour imaging with all brightness


intensity levels and lower cost of ownership are realised with the long lifetime and low power consumption of LED illumination technology. ■

Touch panel improves productivity of existing plant


T


he interface between man and machine often provides potential for optimisation in automated production. In particular


increases in efficiency in the operation of plant contribute to improved production results overall. In the application under consideration, the


existing control units of the centrifuge have been adapted to state of the art technology in order to increase the speed of the system. BARTEC replaced the old panel on site


with the modern 12.1-in widescreen touch panel of the POLARIS Professional series, suitable for use in potentially explosive atmospheres. Indeed, modernisation of the centrifuge control was absolutely necessary: centrifuges used in the chemical industry are part of a highly flexible production system and are constantly being configured for the preparation of different formulations. But the far too long response times when entering new commands impeded the operator in his work and slowed production. A more convenient


and faster system for operation was necessary, but without changing the existing plant, and it had to be suitable for use in potentially explosive areas, since the materials processed in the centrifuge contain solvents.


30 www.engineerlive.com For this reason the customer was looking for


an option to upgrade his existing plant without high engineering costs. As a specialist in industrial safety technology for use in potentially explosive areas, BARTEC had the right solution and offered the added benefit of flexibility. In the POLARIS Touch Panel with Ethernet


interface, communication, imaging and processing using the keypad work in parallel. As soon as the next log retrieval takes place, all parameters are already updated.


The communication processes run in the


background using a Modbus/TCP protocol, new entries are entered and integrated directly. The appropriate response is immediate. This means that all commands are executed almost immediately after entering and the objective of near real-time operation under hazardous conditions has become tangible. ■
