Project ID: S&T11
Background to Research Project:
Climate change due to emissions of greenhouse gases (GHGs) is one of the most significant long-term environmental challenges facing the world and CO2 has been the largest contributor to the GHG emissions for about three decades. This is largely due to increased energy needs across the world with fossil fuels remaining the highest source of power generation. Carbon Capture and Sequestration (CCS) is an emerging method of reducing GHG emissions of Power Plants.
Plantwide control approach of designing Control structures and strategies for Process Plants considers the Plant holistically as opposed to the traditional methods of control design of individual units before coupling them together thus leading to undesirable and unwanted interactions in the system.
Statement of the problem:
The incorporation of Post-combustion CO2 Plants into Power Plants has proven to be efficient for the removal of CO2 but the inclusion of such modifications in the Power Plant increases the complexity of the overall cycle. The key drawback of this process is the high energy penalty, in particular to regenerate the solvent in the stripper column. This however qualifies the Power plants to be integrated with carbon capture for Plantwide Control studies. Also, the presence of mass recycles in the regeneration process of Monoethanolamine (MEA) and fewer inventories make the need for Plantwide Control more pronounced. However, Plantwide control studies carried out so far have been limited to the CO2 capture Plants without the incorporation of Power Plants. Thus, there requires a need to extend Plantwide control to the combination of Plants which is the Power Plants integrated with Carbon capture Plants.
Expected outcomes and contribution of this research:
The Control structure proposed in this work will be for the integrated Plant. The ones currently available are the structures developed only for the CO2 capture Plant.
The Plantwide Control studies on the integrated Plant are expected to produce a flowsheet for the Plant with optimum operating conditions.
Significance of the research:
Post-Brexit, CCS plays an effective role in helping the United Kingdom (UK) to achieve net-zero greenhouse gas emissions with a 64% reduction by 2050 and protecting the planet.
The integration of Fossil fuel Power Plants with CCS Plants makes the Power Plants to still be relevant for electricity generation with net zero CO2 emission.
CCS is a key solution in decarbonizing other Industries like glass, steel, Oil and Chemical refineries.
