In the hydrocarbon industry?i.e.,
oil refineries, petrochemical plants, gas plants, and exploration and
production facilities?it is often necessary to separate gas from liquid at a
certain stage of an operation or process. The operating conditions of the mixed
phases and the requirements for separation efficiency may vary widely.  Therefore, special care should be taken in
selecting the most appropriate device to match the specific duty.

For a bulk gas-liquid separation,
where generally not more than 95% of the liquid must be removed from the gas
stream, the Schoepentoeter has proven to be one of the most effective devices
available on the market. The Schoepentoeter is a Shell proprietary feed inlet
vane device commonly used for introducing gas-liquid mixtures into distillation
columns or gas-liquid separators.

In most of the cases, the
conventional Schoepentoeter has been proven to provide very good performance,
and even to exceed expectations.

There are indeed only a few
applications, e.g., refinery vacuum towers, where the separation efficiency was
measured to be lower than expected.

To comply also with the most severe
services, Sulzer Chemtech and Shell Global Solutions have jointly developed the
new Schoepentoeter Plus which substantially improves the performances of the
conventional one.
