General
Information
- Carbon capture and
storage (CCS), alternatively referred to as carbon capture and
sequestration, is a means of mitigating the contribution of fossil
fuel emissions to global warming.
- Carbon capture and
storage (CCS) is the process of removing or reducing the CO2 content
of streams normally released to the atmosphere, and transporting the
captured CO2 to a location for permanent storage.
- There are three basic
types of CO2 capture: post-combustion, pre-combustion, and
oxy-combustion.
- CO2 can be captured
from a wide range of large sources, such as process streams, heater
and boiler exhausts, and vents from a range of industries, such as
power generation, cement production, refining, chemicals, steel and
natural gas treating.
Process
- CO2 capture
processes from power production fall into three general
categories: flue gas separation, oxy-fuel combustion in power
plants and pre-combustion separation.
- The process is
based on capturing carbon dioxide (CO2) from large point
sources, such as fossil fuel power plants, and storing it in
such a way that it does not enter the atmosphere.
- Carbon dioxide
capture and storage (CCS) is an important concept to reduce
greenhouse gas emissions, in particular from power plants. After
CO2- capture the CO2 needs to be compressed to achieve the right
transport and storage conditions.
- Once captured, the
CO2 is compressed, dried and transported to a suitable storage
location such as saline aquifers, depleted oil fields and
depleted gas fields.
Uses
- The carbon
capture process has been used for several decades in the
petroleum, chemical, and power industries for a variety of
reasons relevant to those industrial processes.
- Most
applications of CCS in industry – for example for boilers,
turbines, iron & steel, furnaces and cement kilns - require
a capture step to concentrate relatively dilute streams of
CO2 to a level that will enable economic transportation and
storage.
- Carbon dioxide
capture can be used for the following applications: CO2
sequestration, Enhanced oil recovery (EOR), Merchant CO2
sales, Chemical feedstock production.
- Capturing CO2
might be applied to large point sources, such as large
fossil fuel or biomass energy facilities, industries with
major CO2 emissions, natural gas processing, synthetic fuel
plants and fossil fuel-based hydrogen production plants.
Report
-
Worldwide, there are today several operational
largescale projects, along with numerous smaller
facilities, demonstrating specific elements of the
carbon capture process.
- In
past year, there were approximately 5,800 km of CO2
pipelines in the United States, used to transport CO2 to
oil production fields where it is then injected into
older fields to extract oil. The injection of CO2 to
produce oil is generally called Enhanced Oil Recovery or
EOR.
- CO2
sequestration technologies entailing of CO2 capture,
transport and storage underground or at depth at sea,
could be an immediate potent counter measure to global
warming issues.
- CCS
costs depend on factors such as fuel, technology,
location, national circumstances and potential CO2 use.
-
Geological storage in saline formations or depleted oil
or gas fields typically cost US$0.50–8.00 per tonne of
CO2 injected, plus an additional US$0.10–0.30 for
monitoring costs.
