3 Current fuel programs specify drastically reduced limits on sulfur levels for gasoline, kerosene and diesel fuels used in engines ranging from vehicles, jets and ocean-going vessels. These programs will yield enormous long-term benefits for public health and the environment. Major oil companies emphasize the importance of hydrotreating a refinery process for reducing sulfur, nitrogen and aromatics while enhancing cetane number, density and smoke point. Fast changes in spot market prices for both crude oil and products have forced refiners to plan investments for higher operational flexibility. Hydrocrackers are a key factor in achieving greater refinery agility to comply with market fluctuations while maximizing refinery margins. With a focus on hydrotreating, hydrodesulfurization and hydrocracking processes, MAN Diesel & Turbo used its proven barrel compressor and steam turbine technology to create the high-efficiency modular packaged compressor unit named (ReTPac). 3

4 Sulfur-Free Diesel and Gasoline Environmentally friendly solutions thanks to MAN Diesel & Turbo compressors Hydrogen makeup Recycle gas compressor Furnace Hydrocracking reactor Fresh feed Pretreating reactor Product fractionator H 2 -rich gas Process gas Naphtha High-pressure separator Middle distillate Low-pressure separator Typical hydrocracking process scheme Lube stock Driving demands increase of 350% in diesel and gasoline production over the last 5 decades stricter environmental laws. Limitations regarding ultra low sulfur content in fuels higher operational flexibility demands on refiners due to fast changes in spot market prices short delivery times for long lead items and documentation upgrade and service-friendly rotating equipment ReTPac targets centrifugal compressors in hydrotreating and hydrocracking applications modular configuration, pre-engineered, packaged design which provides: - maximum flexibility in compressor train component selection - fast delivery for materials and documentation - easy maintenance, good access - fast erection and short commissioning time - easy to upgrade, modular design - attractive price 4
