Pipeline Operators and Transmix Desulfurization
Addressing Sulfur Contamination in Transmix
Fuel pipelines often carry various products sequentially, which leads to intermixing at interface points. When high-sulfur fuels move through the system, they contaminate adjacent batches. This contamination, called transmix, often exceeds acceptable sulfur limits and cannot meet regulatory fuel standards unless treated.
Onsite Sulfur Polishing at Terminals
Desulfurization systems designed for terminal use enable onsite treatment of transmix. These systems allow pipeline operators to restore contaminated fuels to specification without transporting them off-site. By treating fuels directly at the source, operators reduce delays and avoid added reprocessing or transportation costs.
Compact Systems for Distributed Infrastructure
Desulfurization technologies suited for transmix generally use compact units that fit within existing terminal layouts. Their simple design minimizes space requirements and construction needs, making them adaptable for deployment at remote or decentralized facilities. Batch processing capabilities also allow for flexibility in operational planning.
Lower Emissions and Energy Consumption
These systems typically operate without hydrogen and under ambient conditions, reducing both energy consumption and emissions. Advanced catalytic processes remove sulfur efficiently while generating significantly lower CO₂ emissions—up to 70% less than conventional hydroprocessing methods. As environmental regulations tighten, these reductions support compliance and sustainability efforts.
Enhanced Operational Efficiency
Operators can treat and return transmix fuel to terminal inventory efficiently. Compact units help maintain throughput, reduce product loss, and lower overall treatment costs. By avoiding off-site transport and reducing reliance on energy-intensive systems, pipeline networks maintain flow while meeting fuel quality standards.
