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 tech-

nology to create the high-efficiency modular packaged compressor unit named

Refinery Train Package (ReTPac).

Modular Packaged – Flexible SolutionHydrotreating and hydrocracking compressor packages

Modular configuration

The modular configuration ranges from pre-engi-

neered train components such as centrifugal barrel

type compressors, coupling, mechanical drive steam

turbines and baseframe to system components such

as lube- and control oil system, dry gas seal condi-

tioning system and unit control panel. This concept

ensures maximum flexibility in the selection of com-

pressor train components without compromising on

efficiency and reliability.

Features and benefits
