Biogas Process Overview Biogas Upgrading

Example of a CApure Plant

Protecting Our Environment

99.9% Methane Efficiency

CApure technology achieves the highest methane recovery, reducing methane slip to less than 0.1%. There is no hidden additional cost or energy requirement associated with treating the tail gas and harmful emissions to the environment are avoided. The long life, biodegradable organic solvents used in the CApure process are part of a closed-loop system keeping water consumption to a minimum

CApure Operation & Benefits

Local Production of (bio)LNG

• Over 99.9% Methane Recovery • Over 99% Methane Content in

Product Gas • Less than 0.1% Methane Slip • Ability to Blend CO2 back for CNG

(97%) • C02 Can be monetized • <0.0031kwh/scfm Energy

Consumption

Increased Revenue Meets pipeline specs.

Reduced Environmental Impact Increased gas volume / revenue

Additional Revenue Stream Low operational Cost

CApure Technology

• Plant operates from 20% - 100% Capacity

• Ability to Re-circulate out of spec Gas

• Closed Loop Regeneration System • Fully Automated Operation • Removes VOCs and Siloxanes

Increased operational flexibility No Need for Stop Start Operation

Less Water Consumption Reduced Site Supervision Meets Gas Pipeline Specification

Proven Technology Manufactured to a High Quality

Standard 98% Availability Guarantee Easy Access for Maintenance Whole Life-cycle Service Support Performance Guarantee

Lifetime Quality – Optimum Performance

Barriers and Opportunities

• Permitting, dispersed on too many regulatory agencies.

• Think Film LA as a model to streamline permits

• Pipeline interconnect fee • How can cost be brought down?

• Lack of local “model” examples • SB1383 and other will make more organic material

available for biogas production.
