Amur GPP – A Showcase of Cryogenic Gas Processing
Combined NGL/NRU with He Recovery
Each NGL/NRU unit is designed for a
feed gas processing capacity of 7
billion standard cubic meter per year
(~ 875,000 Nm³/h).
Each unit consists of four sections:
• NGL Recovery unit
• Nitrogen / Helium Rejection unit
• Heat Pump unit
• Deethanizer unit
Each helium purification &
liquefaction unit is designed for an
annual liquid helium production
capacity of 20 million Nm³.
6 x NGL separation and nitrogen rejection units ("NGL/NRU")
3 x Helium purification & liquefaction units

Amur GPP
CO2-Tolerant Design and Maximum Sales Gas Pressure
Special Design Features
• Proprietary process to prevent freeze-out of CO2 up to 3.000 ppm and hereby avoiding upstream amine wash
units and large dryer units
• Maximum feed gas pressure through cold integration across various process units with heat pump minimizing
sales gas compression equipment and energy
Key design features:
• Feed gas with 8 mole% N₂ and 0.5 mole% CO₂
• Sales gas with less than 2 mole-% N₂
• High purity ethane and C₃₊ product
• Liquid helium grade 5.5 with 99.9995 mole%
purity
• Integrated NGL/NRU

Ust Luga Gas Processing Plant – Process Concept
Large NGL Recovery with CO2 Tolerant Design
Four NGL trains, each designed for a feed gas
processing capacity of 11.25 billion
standard cubic meter per year (~ 1.3 Mio
Nm³/h).
Key Design Features
• Turboexpander driven process without
applying external refrigeration
• Highly efficient plate fin heat exchangers
allow for small temperature approach
• High Ethane recovery rate due to
additional sales gas recycle
• CO2 tolerant design without need for
upstream CO2 removal unit
