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

9

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
