OPERATIONS AND MECHANICAL AUDIT OF A DEDUSTING UNIT FLEET (LEAD SMELTER)

ISSUE

Lead smelters operate many dust collectors to capture process­ lead emanations. STS Canada was commissioned for an audit of operations and mechanical integrity of these dust collectors units (88 units). The objective was to determine the level of conformity of each piece of equipment. These results were then used to determine the actions that needed to be taken to increase equipment efficiency and longevity.


TECHNOLOGICAL CHALLENGE

This project required careful planning of maintenance operations on the dust collectors, so as to cut down on dead times and to optimize maintenance and operations personnel working hours.


RECOMMENDED SOLUTION

Tools developed by STS Canada were used to identify critical equipment in need of immediate attention (including a scaled evaluation and a criticality rating). Activities that were categorized as priorities were also ranked in order to help our client prioritize his actions.

The approach used with internal auditing documents and personnel interviews enabled us to meet the initial objectives and ensure the project’s success.

RESULTS

The results obtained allowed the client to build himself a dust collector upgrading program, which included a prioritized list of actions to be taken. In the end the Ministerial requirements for atmospheric emissions were fulfilled.
