EVENT REPORTED by SAM GUARD®

SAM GUARD® detected level fluctuations in a Benzene-Water separator in a chemical plant since 16.07.2023.

There was an issue in this separator also in the past with bad sensor issue because of line blockage, so the issue was particularly interesting.

MAINTENANCE TEAM FINDINGS

Blockage is a consistent issue particularly in this part of the plant.

There was an initial alert in Aug 2023, and it was assumed that the maintenance had already cleared the blockage but there second alert in Oct 2023, showing the same issue.

COST / DOWNTIME AVOIDED

Blockages are difficult to catch earlier because of higher DCS alarm limits and SAM GUARD® helps to solve this issue and maintenance action can be made earlier.

CUSTOMER FEEDBACK

“The issue was overlooked, and the second alert on the same asset helped to follow-up on the failure without leading to a bigger failure.”
