Adsorbents for Contaminant Removal from FCC Derived Ethylene and
Propylene Streams
The UOP Fluid Catalytic Cracking (FCC) unit is the workhorse in many
refineries. The process is highly flexible and is used to crack atmospheric
and reduced crude into lighter fractions. The C2 (ethane and ethylene)
as well as the C3 (propane and propylene) fractions are quite valuable,
since they contain significant quantities of olefins that can be recovered
and sent to polymer processing plants. The UOP Propylene Recovery unit
(PRU) is a part of many FCC units.
UOP offers adsorbent products that can remove contaminants present in your
ethylene and propylene streams to help you meet monomer feedstock specifications
that are often in the parts per billion (ppb) range. Highly specialized adsorbents
for dehydration, sulfur (H2S and COS), oxygenates (CO2),arsine (AsH3) and mercury
are used either in separate vessels, or as separate layers in a single vessel
to minimize your capital outlay.
These commercially proven products are uniquely designed to work effectively
in highly reactive olefinic streams, without forming by-products or causing
temperature runaways as a result of unwanted reactions.
