http://www.che.com Chemical Engineering en-us 2013 Thu, 23 May 2013 4:28:15 EDT Compressors are a workhorse of the CPI. A variety of technologies, methods and best practices are available to obtain the lowest cost of ownership for compressors used in process plants. Follow the guidance presented here to get the best value from each compressor over the life of the unit... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/compressors/10473.html Wed, 1 May 2013 0:00:00 EDT The main challenge for a complex, integrated configuration — in which the fluegas from a gas turbine is combined with a downstream chemical process unit such a furnace or waste-heat-recovery unit — is to design a system that maintains optimal operating flexibility for both the upstream and the downstream components... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/compressors/10295.html Fri, 1 Mar 2013 0:00:00 EST This article is intended for readers who want to gain a basic understanding of the components of a compressed air system. It also presents best practices that will prove helpful to a process engineer writing specifications for such a system.... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/compressors/10085.html Tue, 1 Jan 2013 0:00:00 EST When it comes to rotating machinery (pumps, compressors, gas turbines, steam turbines, turbo-expanders, and others) operating in the chemical process industries (CPI), installation, piping, support, pre-commissioning, commissioning and startup play crucial roles. Machinery maintenance and repair can be quite costly, and perhaps because of shortages of skilled manpower, particularly at remote site locations, CPI plants have given less attention to technical details for machinery installation, piping and commissioning.... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/compressors/9994.html Sat, 1 Dec 2012 0:00:00 EST Topics of other recently published chemical engineering titles include: material damage, renewable energy processes, thermocouple thermometry and more... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/compressors/9887.html Thu, 1 Nov 2012 0:00:00 EDT One of the most significant limitations on the operation of dynamic compressors (axial and centrifugal compressors) is the low-flow limit known as “surge”. A sudden valve closing, such as for emergency shutdowns or for a suction/discharge valve, presents significant challenges to anti-surge valve sizing and selection. Anti-surge valve requirements depend to a large degree on the compressor type, the compression system arrangement, and particularly the volume of the discharge piping downstream of the compressor. Important aspects of anti-surge valve sizing and selection for plants in the chemical process industries (CPI), as well as examples, are discussed in this article.... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/compressors/9903.html Thu, 1 Nov 2012 0:00:00 EDT There are two main reasons why compressor capacity regulation is used. The most prevalent reason is to adjust the suction flow to match the process demand. The second reason is to save energy. As a rule, capacity control is determined by the compressor discharge pressure. Compressor capacity-control methods are utilized to maintain a required delivery under variable process conditions. In this article, methods for controlling the capacity of reciprocating compressors are... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/compressors/9687.html Sat, 1 Sep 2012 0:00:00 EDT The OPK-341 Industrial Leak Detection Kit is designed to help locate fluid leaks in hydraulic equipment, compressors, engines, gearboxes, as well as fuel and other synthetic and petroleum-based... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/compressors/9565.html Wed, 1 Aug 2012 0:00:00 EDT Kobe Steel, Ltd. (Tokyo, Japan; www.kobelco.com) says it will establish two 100% owned companies in July, one in Europe and the other in the Middle East, to expand the global marketing and servicing of its compressors. Kobelco Machinery Europe GmbH will be set up in Munich, Germany to strengthen the... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/compressors/9472.html Wed, 27 Jun 2012 0:00:00 EDT The growth in use of centrifugal compressors in chemical process industries (CPI) applications in recent decades has been brought about by four factors: 1) advances in dry gas seal technology; 2) modern aerodynamic, rotor-dynamic and thermodynamic knowledge and techniques; 3) advanced manufacturing methods to producing accurate rotating parts and various complex components with reasonable costs; and 4) the ability to simplify the control and anti-surge systems of a centrifugal compressor (and its driver) through the use of modern control and variable-speed technologies. With these advances, and because of their simplicity, reliability, light-weight, and compact design, centrifugal compressors have become... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/compressors/9296.html Tue, 1 May 2012 0:00:00 EDT
