Objective
With the support of the European Commission awarded in a previous THERMIE call a 335 MW (gross ISO) highly Integrated Gasification with Combined Cycle (IGCC) demonstration plant is being constructed at Puertollano (ES). This plant will demonstrate the technology and will be the world largest IGCC power station. The activities in this project proposal are focused at developing various tools and systems within a unique work programme to :
(i) improve the overall performance of the Puertollano base concept while supporting the start-up and operation activities, and
(ii) enlarge the knowledge base during the early operation of Puertollano, which when used in conjunction with extensively validated computer models will lead to the assessment of more cost effective IGCC concepts.
The pursued objectives shall help promote this environmentally clean technology and meet the challenges of the IGCC technology. It will also enhance the applications of the latest modelizations/simulation techniques for advanced cycles improvement.
The 335 MW (gross ISO) IGCC plant being conducted at Puertollano is based on a highly integrated coal gasification with combined cycle. A unit of air separation provides the oxygen and nitrogen necessary for the process. In essence the plant fundamentally consists of three integrated islands: coal gas generation and treatment, combined cycle, and air separation unit. In the gasification island, the feedstock of coal, petroleum coke and lime is milled and dried before entering the PRENFLO gasifier. The coal dust is gasified with oxygen at a purity of 85% vol. The gasification process is based upon an entrained-flow principle. The raw gas produced is quenched at the outlet of the gasifier with dust-free gas and cooled down in a HP and IP waste heat boiler system to generate steam. The cooled gas is then dedusted in a ceramic filter.
The gas is then cleaned to remove the sulphur and halogen species, further conditioning (NOx control and nitrogen dilution) takes place before enteringthe combined cycle. The sulphur is recovered as elemental sulphur and the other by-product is an inert slag. The combined cycle consists of a Siemens advanced gas turbine V94.3 model with an output of 190 MW (ISO conditions), a triple pressure heat recovery steam generator and a reheat steam turbine of 145 MW. The air separation plant operates under pressure as a cryogenic process directly fed from the gas turbine compressor outlet.
In addition to the main plant islands, and due to the high degree of integration, the design of the interface systems and controls is specially relevant to assure high plant reliability and availability. The understanding of these processes is an expected outcome from the proposed work program.
The innovative complex and highly integrated nature of the IGCC plant above described requires a comprehensive approach to understand the mechanisms affecting the plant performance and availability. A thourough understanding is essential to formulate the designof the next generation of IGCC plants. Our project proposes the approach of made up of state-of-art techniques in the fields of dynamic and steady-state simulation, operation diagnosis, materials behaviour and environmental impact of several activities.
The activities are focused at developing tools and systems to support the start-up and operation of the Puertollano plant, as well as assessing the current and future IGCC design concepts. The program will be conducted under the coordination of the Technology Group, recently established in ELCOGAS with participation of the company shareholders, research departments of the participating utilities, external research centers and/or universities and, of course ELCOGAS itself. In addition, exchanges with the technology supppliers (Siemens AG, Krupp GmbH and Air Liquide) are foreseen in the relevant conclusions of the work program.
This project has developed various computer based plant models which used plant information as it became available.
