CO2-Recovery Plant 39 EN/2020
7. Risk assessment
7.1 Chemical hazards:
The DALUM CO2 recovery system utilizes compounds such as selexorbs and active carbon
that can be hazardous if not handled properly. Exposure to these chemicals can cause skin
irritation, eye irritation, and respiratory problems. It is important to provide appropriate protective
equipment and training for employees who will be working with these chemicals.
7.2 Equipment malfunctions:
The CO2 recapture system utilizes various components, such as compressor, pipelines, and
storage tanks, which can malfunction or fail. Such failures can lead to the release of CO2 gas,
posing risks to workers and creating asphyxiation hazards in poorly ventilated areas. Regular
inspections, maintenance, and testing are necessary to ensure the proper functioning of the
system and identify and address any potential issues.
7.3 Pressure hazard:
The DALUM CO2 Recovery Unit operates at internal pressures of up to 45 bars. This pressure
can be dangerous if it is not properly controlled and managed. 45 bars are equivalent to
approximately 650 psi (pounds per square inch), which is a relatively high pressure that can
cause injury or damage if it is suddenly released or handled without proper precautions. The
level of danger associated with a pressure of 45 bar will depend on a number of factors,
including the volume of the pressurized substance, the type of container or pipeline used to
contain it, and the environment in which it is stored or transported.
To minimize the risk of injury or damage, this pressurized system should be installed and
maintained according to appropriate safety standards and guidelines. It is important to use
appropriate safety equipment and to follow established procedures for handling and using
pressurized substances. If you are unsure about the safe handling of a pressurized system or
substance, it is important to seek guidance from a qualified expert or professional.
7.4 Fire hazards:
The DALUM CO2 recovery system utilizes electrical equipment that may pose a fire hazard if
not maintained and grounded properly. The release of CO2 gas in a poorly ventilated area can
displace oxygen, creating a fire hazard. To prevent such incidents, fire suppression systems
should be installed, and employees should receive training in fire safety procedures.
