Best practices in treating liquefied petroleum gas are defined
Advantages of removing H2S before the LPG unit and energy optimization of the LPG splitter
This article presents the basic engineering design of a
liquefied petroleum gas (LPG) recovery unit at the Khuzestan
oil refinery, Iran. This refinery, like other oil refineries,
consists of one LPG recovery unit. The feed to the LPG recovery
unit comes from three different sources. The first feed is from
a catalytic cracking reforming (CCR) unit that is completely
sweet with no H2S content. The second feed is from a
hydrocracking unit that is sour and has H2S content.
The third feed comes from a stabilizer in the crude distillation unit (CDU) which is
also sour and has H2S and mercaptan
