It said the exercise, which started in June this year, had seen the removal of the entire furnace, leaving behind only concrete stands on which the furnace sat.
The installation of the new furnace was completed in October last year, but exploded on January 17, 2017, when technicians on duty attempted to restart the equipment which had gone off suddenly while refining crude oil.
This occasioned an emergency shutdown of the facility to avert any fire incident or other hazards.
The furnace was commissioned on December 2, 2016 at the cost of €5 million, as part of an expansion project carried out by TOR to increase its processing capacity.
The Daily Graphic gathered that all the tubes inside the furnace which transmitted crude oil to be heated prior to processing got damaged in the incident.
Similarly, the furnace shell, the refractory material (a chamber that retains heat at high temperatures) as well as the instrumentation in the furnace, among other vital parts, also suffered severe damages, rendering them useless.
According to the sources, the manufacturer was supposed to replace the furnace at the cost of about €3.5 million. According to the source, management of the refinery had been holding discussions with the manufacturers and the insurers on the replacement and “indications are that the replacement could be brought in by the end of 2017,” the source said.
It added that some spare parts of the damaged furnace had been identified to be in good condition and as such could be used to replace the dameged parts.
The Daily Graphic also gathered that the refinery’s management was yet to take a decision on the report of the internal committee investigation which recommended sanctions against some technicians and operators who were on duty on the day of the explosion.
Resumption of operations
Operations at the refinery, which were also suspended in February this year to pave way for a turnaround maintenance, are also expected to resume in the next three weeks. The refinery last conducted a turnaround maintenance in 2009.
According to the source, although the maintenance was anticipated to have been carried out within a shorter period, delays in the procurement and delivery of some essential spare parts for the refinery prolonged the maintenance period.
“The Crude Distillation Unit (CDU) is, however, being prepared for production, while the Residual Fluid Catalytic Cracker (RFCC) comes on stream when the CDU is able to generate adequate raw material for it to be used to process liquefied petroleum gas (LPG) among other by-products,” the source added.
Attempts to reach management of the refinery for comments were unsuccessful. The acting Managing Director, Mr Isaac Osei, did not answer the phone calls.
