Coal remains a vital energy source in the Philippines, powering industries and ensuring energy security. In 2023, coal-fired power plants generated 61.9% of the country’s electricity. A major 300-megawatt power plant in Mindanao plays a key role in sustaining national energy needs.

To maintain continuous operations, this power plant requires at least 300 tons of limestone powder daily. The limestone powder is essential for reducing sulfur dioxide (SO₂) emissions, and it must be efficiently transferred into storage silos.

Previously, a 40-ton bulk carrier truck relied on its built-in air compressor, taking up to 4 hours to load limestone powder into the silo. However, after switching to the Atlas Copco XAHS 400 PACE portable air compressor, the same process now takes just 30 minutes—a remarkable 87% time reduction.

This dramatic improvement in efficiency allows the plant to streamline operations, reduce energy costs, and enhance overall productivity.

Coal power plants must comply with strict emission regulations. One of the most effective ways to reduce SO₂ emissions is by injecting limestone powder into the system. The limestone reacts with SO₂, forming calcium sulfate (CaSO₄)—a solid byproduct that is safely captured using baghouses or electrostatic precipitators before reaching the atmosphere.

At the Mindanao power plant, the XAHS 400 PACE compressor ensures an uninterrupted supply of limestone powder to the injection system. Its high-pressure air delivery enables rapid material transfer, helping the plant meet environmental standards while maximizing productivity.
