Agenda
• Gas Processing Portfolio
• Separex Membrane Technology
• Mercury Removal Adsorbent Technologies
• Honeywell UOP Modular Gas Plants
UOP Separex Membrane Elements
• Membranes are thin, semi-permeable barriers that selectively separate certain components
• Membranes are characterized by permeability or capacity (flux) and selectivity

Hybrid schemes – Combining the Best of Two Worlds
GrassrootsBulk-cut with membranes
• Very attractive offshore to allow lower
weight and footprint and reduce
transport volume, or,
• Meeting pipeline spec at wellhead and
further reducing to LNG spec
downstream
RevampDebottleneck existing amine units
• Increasing feed gas flowrates, or,
• Increasing feed gas CO2 content
membrane will treat the gas to a
CO2 content that is acceptable to
the existing amine unit

Why remove Hg?
1. Health, Safety & Environment
2. Equipment Protection
3. Catalyst Protection
4. Product Quality
UOP Guard Bed Adsorbents
• Non-Regenerative System
• Removal to 0.01μg/Nm3 Hg
• Also combined with removal
of H2S, RSH and COS
• No dry stream required
• Used in more than 70 units
UOP HgSiv Adsorbents
• Regenerative System
• Removal to 0.01μg/Nm3 Hg
• Also combined with Molsiv
adsorbents for removal of
H2O, H2S, RSH and CO2
• Small layer in Molsiv Unit
• Used in more than 50 units

Why Modularize?
More assembly work is done in the shop at a lower hourly rate and not subject to weather
Equipment and parts are more
readily available at the shop location,
closer to supplies
Much assembly work can be
completed prior to field move in,
while waiting on permits and
weather
Equipment, piping, and
instrumentation can be checked
out prior to shipment to
fieldCo
