Honeywell improves safety at petrochemical plant

Honeywell improves safety at petrochemical plant
Petrochemical Corporation of Singapore invest in plant and personnel safety with installation of state-of-the-art fire and gas system.


Petrochemical Corporation of Singapore (PCS) is a major producer of ethylene, propylene, acetylene, butadiene, 1-butene, MTBE, benzene, toluene and xylene, and was facing issues with their aging fire and gas system originally installed 20 years earlier. The system was out of date, unreliable, and spare parts were hard to come by. Spotty support further put the operation at risk. Having strong experience with the existing Honeywell DCS, PCS requested Honeywell to study and upgrade the fire and gas system to the state-of-the-art Honeywell XLS3000 Fire and Gas system with a proven track record for reliability. Since the field devices were up to date and performing to expectations. PCS limited the project scope to study and upgrade only the main F&G Controller and the IO components.


Since the project scope was to replace only the controller and not the entire F&G system the challenge became to decommission the old system, and install new wiring between the existing field devices and the new XLS3000 controller with the I/O components, without disrupting operations.


PCS requred that the new fire alarm panel provide the same functionality as the existing panel and more. Following evaluation of several offerings, PCS selected the Honeywell XLS3000 Fire and Gas System based on its capabilities, reliability and field-proven track record. In addition, PCS installed Honeywell's EBI R410 SCADA system with HMI Graphics. The new panels were connected to the network via fiber optic cables. Honeywell took responsbility for the installation, testing and startup of the entire system.

The Honeywell XLS3000, part of the XLS Series of products, is an intelligent Fire Alarm Control Panel designed for medium to large-scale facilities. Fire emergency dtection and evacuation are extremely critical to life safety, and the XLS3000 is dieally suited for these applications.

The XLS3000 solution was a very good fit for the PCS project as its modular design could be specifically configured to meet the PCS project-specific requirements. With one to ten Signaling Line Circuits (SLCs), the XLS3000 supports up to 3,180 intelligent addressable devices.

The large 640-character Liquid Crystal Display (LCD) of XLS3000 presents vital information to PCS operators concerning a fire situation, fire progression, and evacuation details in case of an event. The display allows up to nine users, each with a unique password and pre-determined access levels. The display has 11 LED indicators including Power, Supervisory, Point Disabled, Fire Alarm, System Trouble, CPU Failure, Pre-Alarm, Other Event, Controls Active, Security, and Signals Silenced.

Membrane switches are sued for Acknowledge, Signal Silence, Drill, System Reset, and Lamp Test. The XLS3000 is designed to meet most global agency listing and approvals.

Honeywell also provided the Enterprise Buildings Integrator (EBI) R410 SCADA system with graphic operator interface, seamlessly integrated with the XLS3000. EBI R410 is a highly configurable integrated buidling management system providing an efficient and reliable means to ensure the security, safety and comfort of people and the ffective operation of the PCS plant facilities. Its integrated Life Safety Manager provides operators, supervisors and managers with a sophisticated web-style interface to enable PCS personnel to easily monitor the fire alarm system from a single interface during emergency situations.
