Coker Valve Switch Project

PROJECT DESCRIPTION

The primary objective of the project was to provide a protective interlock system to prevent inadvertent operation of Coker valves “out of sequence”.  The scope included:

• Automation of approx. 144 valves; 120 with new MOV actuators and 24 modifications to existing MOV actuators
• Addition of new valves for “double block” configuration on condensate and blowdown lines
• Provide a new RIE to house Triconex SIS, Honeywell DCS equipment and redundant UPS equipment
• Provide new SIS and Process Control systems included 3 new Triconex TMR systems, 1 HPM and 2 HMIs running with Wonderware graphics
• Installation of new Priority 1 Alarm/Bypass Displays @ Coker Control Room Console
• Networking of new SIS and Process Control Systems involving new fiber optic backbone and network switches
• 480 Volt distribution for RIE and MOVs
• Paton’s scope includes:
