OPERATION & MAINTENANCE OF POWER PLANTS
ring mains and local control panels. Carbon capture plants with many control valves will see real power savings with electric actuation due to their relatively low power consumption compared to pneumatic alternatives.
Te CCS industry is at a key stage of
development. Many industries, such as power generation, have been encouraged to adopt CCS technologies. Some emerging technologies are nearing maturity and are being tested to establish if they can be scaled up to commercial levels. Many countries are confident that the cost per tonne of CO2
capture will likely decrease
over time. Flow control is central to the operation
of key processes in CCS. Whether plants are capturing carbon pre- or post- combustion, transporting it for use or long- term storage, flow control solutions should be carefully considered and specified.
THE ROLE OF ELECTRIC ACTUATION Intelligent electric actuation offers solutions to specific problems in the CCS industry, for sites with smaller capture volumes, land or sea transport is used. Te captured CO2
is transported to industrial hubs
and combined with CO2
from other
sources to be distributed to points of use or long-term storage. Intelligent electric actuators can help support the transport of carbon dioxide from the point of capture to the point of use. Accurate and reliable actuators provide modulating flow control to pipelines, transport vehicles, vessels, or short-term storage. Electric actuators have a low lifetime
cost of ownership. Many Rotork products are sealed for life, resulting in longevity. Commissioning and maintenance are non-intrusive, with a comprehensive user interface, removing the necessity to break the seals. Operation, tuning and testing can be performed from a pivotal point, removing the need for maintenance engineers to travel. One of electric actuators’ key design considerations is minimising their energy usage. Tis reduces OPEX and lessens the customer’s “carbon footprint”. Te next generation of the CCS market is aiming towards a low-risk and low- reward business model, so improvements need to be made to meet this goal. Te need for scalable and economically attractive solutions will become more pressing
as the range of CCS technologies expands to include pre- and post-combustion applications. Te cost of capturing CO2
can
vary widely, so flexibility and reliability in selecting the right intelligent flow control solutions will be essential to the continued development of carbon capture.
