TP28 For several years a debate has been underway regarding the benefits of duplex systems versus triplex systems, especially for use in process control (non-safety) systems. Previous attempts at quantifying the differences have generally taken a narrow view by focusing on the control and safety systems as stand-alone hardware platforms, often with overly simplified reliability models. This fails to account for many real-world issues, including the impact of software diagnostic coverage, field-device reliability, and compensating fallback-control strategies. Compressor Controls Corporation has analyzed the benefits associated with duplex and triplex systems.

TP29 Control of complex turbomachines in an ethylene process presents numerous challenges and opportunities because the plant’s production capacity largely depends on their availability, reliability, and efficiency. Among these challenges are: minimizing flare, automation of plant startup, effective compressor surge protection for all operating modes; maintaining narrow surge control margin, turbine overspeed trip prevention, integrated capacity control, refrigeration compressor quench control, and operating closer to the process limit to meet increasing production requirements. Control systems with proven capabilities to solve these challenges can have significant economic impact on Ethylene plant
operating revenues and profitability.

TP30 An ethylene plant’s production capacity depends on the availability, reliability, and efficiency of the turbomachines. Effective constraint control of process and turbomachinery is highly critical. Operating safely at the lowest possible pressure on the suction of the Cracked Gas (CG) compressor to increase ethylene yield; and operating closer to the CG compressor final stage discharge pressure limit to increase production of the plant are major issues faced by producers. Turbomachinery control systems with proven capabilities to solve these challenges can have significant economic impact on ethylene plant operating revenues and profits.

TP35 Remote support services for industrial automation and control systems are the need of the hour.
CCC has developed OnLook™ to serve remote support needs for customers securely and conveniently. A simple plug-and-play OnLook™ device installed at the edge of production area network can be turned on/off as required to manage remote access to site. CCC support engineers connect remotely to the OnLook device and all communication is within a secure encrypted VPN tunnel. Additional features such as dual authentication for CCC engineers, strict preset hardware firewall (included with OnLook™), use of one-time passwords, explicit customer permissions for connection initiation, view-only/read-write access and use of easy chat windows ensures that every part of the remote support session is authentic and authorized. Further, the device will comply with all local IT policies and no firewall reconfiguration is required.
CCC’s OnLook™ solution will result in significant time and cost savings for our customers, increased efficiency, and long healthy lifecycles of CCC control systems. Regular pre-scheduled maintenance checkups, faster and more accurate troubleshooting procedures, and frequent interaction with our customers, will lead to a mutually beneficial association. CCC follows North American Electric Reliability Corporation (NERC) guidelines for Critical Infrastructure Protection (CIP).
