ICM to repair concrete stack in Aruba refinery during plant shutdown :: INDUSTRIAL CHIMNEY MAINTENANCE INC.

MHI Project

The MHI boiler chimney at the Valero Aruba refinery is in continuous service for years between planned outages. This makes it difficult to monitor and assess the condition of the liner inside the chimney.

In the fall of 2007, Industrial Chimney Maintenance Inc. (ICM) inspected the inside of the MHI stack using our HotCamtm enclosure. The HotCamtm is a product developed by ICM capable of withstanding very high temperatures which allows the inside of the chimney to be photographed while it is in use.

The HotCamtm inspection revealed problems with the protective refractory coating on the inside of the brick chimney liner and with the breaching where it enters into the chimney.

The current plant shutdown will be used as an opportunity for ICM to repair the problems on the inside of the MHI stack liner as well as to repair some damaged concrete at the top on the outside of the chimney.

In order to complete these repairs ICM will first erect ladders up the outside of the stack and build a scaffold platform around the top of the chimney. Then a mobile suspended access platform will be erected inside of the chimney liner. The damaged areas will then be repaired and the rigging will be removed from the stack. All work is planned to be complete by the end of September, 2009.
