CO2 Recovery from Refinery

16

Based on the information and data during site survey at Balongan Refinery, we

defined the flue gas sources in which CO2 can be effectively recovered.As a result, we are planning to recover CO2 in flue gas emitted from thefollowing equipment.

- Furnace upstream of the atmospheric distillation unit- Hydrogen production unit- Boilers

We are investigating the most suitable process to recover CO2 emitted fromabove equipment and the number of trains of CO2 recovery unit to be installed.

Eligibility Criteria - criterion 7Risk assessment and management

Risk and safety assessment

Extracted from IPCC Special Report for CCS, CCS CDM M&P(CMP7) and other

materials.Risks of serious environmental and health impacts are assumed to be induced byfollowing occasions.

a. containment failure of above-ground installations

b. seepage from subsurface zone

c. effects of potential induced seismicity or other geological impacts

The methodology defines methods to address these risks appropriately. Regarding risk b.above, it defines methods in line with IPCC Special Report for CCS (See bellow).

Detection and Estimation of seepage

1. Monitoring and interpreting the CO2 Saturation

Collecting information on CO2 saturation, such as seismic data,production data or well logging data.

Interpreting CO2 saturation from data obtained.

2. Simulation based on the actual injection Simulating the saturation of CO2 based on actual CO2 injection,

utilizing the three-dimensional model established when characterizing

storage formation.

3. History matching of three-dimensional model Checking whether interpreted CO2 saturation and simulation based on

the actual injection match. (If they dont match) Calibrating three-dimensional model with other

monitored values. The methodology requires procedures and rationale for calibrating

three-dimensional model.

4. Estimating CO2 seepage (If 3. doesnt work) Simulating injection under condition of CO2

seepage with three-dimensional model. Estimating seepage emissions 23
