Petrobras REPAR refinery suffered years of problems with their boiler pre-heaters, leading to poor temperature control of both the combustion gas and the boiler air supply.

Problems included:

Spirax Sarco realised that during the warmer months, when ambient air requires minimal heating, the boiler preheater temperature control valve would throttle to reduce the steam pressure. This, combined with backpressure in the condensate line, reduced the differential pressure across the steam traps, dramatically reducing preheater capacity. The units would begin to flood with condensate - a condition known as stall - leading to poor temperature control and waterhammer.

This problem led to Petrobras having to maintain the regenerator pre-heater at a higher set temperature, to prevent SO3 from condensing out (producing sulphuric acid) in the regenerator or chimney.

Spirax Sarco were able to provide Petrobras with APT14 automatic pump trap assemblies to solve the problem. Each unit removes condensate under all operating conditions, keeping the preheaters fully drained and efficient.
