ENERGY & CHEMICALS - MAKING GOOD BUSINESS OF YOUR CO2
The Energy & Chemical Industry generates excess amounts of CO2 either from chemical/thermal processes or from combustion. CO2 is also present in natural gas. In most cases, CO2 is not recovered but vented to atmosphere.
There are options, however, to recover, purify and liquefy the CO2 and turn it into valuable products. At Pentair Union Engineering we have decades of experience with profitable sustainable solutions.
We are an innovative company offering advanced CO2 technologies and plants and with a broad spectrum of services we enable you to make good business of your CO2.

Valuable expertise in exploration and production of oil and gas
Bringing crude oil or raw gas to the surface is one thing in the upstream industry. Getting the most out of your effort is another. This is what we at Union Engineering do best.Natural gas may contain CO2 at very high concentrations (>75%), but before the natural gas can be used in petrochemical or combustion processes, the CO2 must be removed. The resulting gas will have high purity, depending on the CO2 recovery technology applied.
Chemical or physical absorbers (amines and alcohols) are widely used in the industry. Natural gas processing plants can purify raw natural gas from:
- Underground gas fields
- Associated gas
Whatever your challenge or need, Union Engineering has the technology and expertise to support you in removing CO2 from your natural gas stream and purifying it to levels suitable for further processing.
CO2 Enhanced oil recovery
25 % or more of a reservoir’s original oil in place can be extracted additionally by using Enhanced Oil Recovery techniques. These figures make EOR an essential part of the business.Various techniques are in use but CO2 has turned out to be a very efficient solution and is the fastest-growing technique.
Until recently, most of the CO2 used for EOR has come from naturally occurring reservoirs. But new technologies are being applied to recover CO2 from industrial applications such as:
- Natural Gas Processing
- Ammonia/Fertilizer and Ethanol production
- Hydrogen plants and Ethylene Oxide plants
As a global leader in CO2 technology Union Engineering is a reliable and trustworthy partner when it comes to EOR projects.

Valuable expertise in processing and refining oil and gas
In the downstream processing industry, there are numerous places where CO2 is produced and considered a by-product. In most cases, this by-product is removed from the process stream and vented to the atmosphere.CO2 however, can be a valuable by-product and should be recovered, purified, and re-used in the Hydrocarbon Processing industry. Examples of processes that co-produce CO2 are:
- Hydrogen production
- Gasification of hydrocarbons (refinery residue, coal)
- Biomass gasification
- Production of ethylene oxide.
At Union Engineering we have years of well-proven experience in turning these raw gas streams into a profitable business for you.
Flue gases
The (refined) fossil fuel is often burnt to generate heat and/or power. All of these combustion processes create vast amounts of CO2 in the flue gasses. Also here, Union Engineering has tremendous expertise and technologies to recover the CO2 and make it fit for re-use.

Recovery Based Unit (RBU) - for high-concentration CO2 streams
Capture, liquefaction, and purification of high-purity CO2 raw gas with a concentration of 95–99% CO2, and can be sourced, e.g., from ethanol production, fermentation process, or ammonia and ethylene production, etc.
Advanced Amine Technology (AAT) - for capturing CO2 from fluegas
Low-purity CO2 raw gas is sourced from the combustion of fossil fuel, lime, or cement kilns and requires an upgrading unit to make it feasible for use in a CO2 liquefaction unit.
Tata Chemicals Europe invests in the United Kingdom's first CCU project
In an innovative application of CCU Technology, the TCE plant will capture carbon dioxide from the flue gasses of TCE’s gas-fired 400 MW steam combined heat and power (CHP) plant, which supplies steam and electricity to the company’s Northwich, England, operations and other industrial businesses in the area.
