INTRODUCTION

Hydrogen has always played an important role in oil refning.

Heavier crude oil, tighter environmental regulations and

increased heavyend upgrading in the petroleum industry are

leading to the increased demand !or hydrogen in oil refneries.

 "he wide implementation o! hydro processing technology leads

to signifcantly increased demand !or hydrogen.

 "here!ore hydrogen management is !ocused on making the

#est use o! limited hydrogen resources and optimi$e its

operation.

  %n addition, hydrogen management practices signifcantly

impact operating costs, refnery margin and &'( emissions.

%IMITATION OF HYDROGEN PINCH ANA%YSIS

 "he targets are set #ased only on the 0owrate and purity

reGuirements and pressure is ignored.

 "he purifcation units< placement is guided on the #asis o!

across pinch, the detailed selection and design o! purifers

are neglected.
