Technologies for Emissions Reduction-Gas Gathering applications

□ Low Emissions TEG Dehydration Units

Integrated capture of BTEX absorbed/released by TEG

□ High Pressure Air Systems

Utilization of pneumatic pressure boosters in lieu of power gas

□ Electric Motor Drive (EMD) Compression

Centralized vs. distributed combustion emissions

□ Infrared (IR) Camera inspections

Advance in leak detection technology

Low Emissions TEG Dehydration Unit

□ Tri-Ethylene Glycol (TEG) absorbs and releases a portion of BTEX HAPs from wet gas stream

□ Steps to minimize BTEX PTE

-Condense and separate BTEX from regenerator overhead

-Capture and recycle all non-condensable overhead vapors

-Hardwire TEG unit to only operate while an overhead vapor compressor is in service

-- Inject methanol as backup to TEG system

High Pressure Air Systems

□ High pressure natural gas is often used as "power gas" in industry to actuate valves and pneumatic equipment

□ EPA Gas Star program encourages the use of instrument air systems where practical, typically where:

-Actuation pressure requirement is 150 psig or less

-Electricity is available at site

□ Utilization of a pneumatic booster/amplifier allows the use of air for actuation pressures up to 600 psig

Electric Motor Drive (EMD) Compression

□ EMD Compression potential benefits:

-Operating Costs

Energy

Maintenance

Downtime

-Capital Costs

-Air Permitting simplification

-Improved Equipment Delivery
