Reduction of Amine Loss during CO2 Recovery from Exhaust Gas of Fossil Fuel-Fired Power Plant by Chemical Absorption Method.

The tendency in the world energy demand seems clear: it can only grow. The energetic industry will satisfy this demand-despite all its dialectic about new technologies-at least medium term mostly with current fossil fuel technologies. In this picture from an engineer’s point of view, one of the primary criterions for mitigating the effects of increasing atmospheric concentration of CO2 is to restrict the CO2 fossil fuel emissions into the atmosphere. This paper is focused on the analysis of different CO2 capture technologies for power plants. Indeed, one of the most important goal to concentrate on is the CO2 capture energy requirements, as it dictates the net size of the power plant and, hence, the net cost of power generation with CO2 avoidance technologies. Here, the Author presents a critical review of different CO2 absorption capture technologies. These technologies have been widely analyzed in the literature under chemical and economic points of view, leaving their impact on the energy power plant performance in a second plan. Thus, the central question examined in this paper is the connection between abatement capability and its energetic requirements, which seriously decrease power generation efficiency. Evidencing that the CO2 capture needs additional technical effort and establishing that further developments in this area must be constrained by reducing its energy requirements. After a comprehensive literature revision, six different chemical absorption methods are analyzed based on a simplified energetic model, in order to account for its energetic costs. Furthermore, an application case study is provided where the different CO2 capture systems studied are coupled to a natural gas cogeneration power plant.

Abstrak. Mesin gasifikasi bertujuan untuk menghasilkan gas mampu bakar (CO, H2, CH4). Gas mampu bakar yang dihasilkan dapat digunakan untuk menggantikan fossil fuel untuk menjalankan gas engine. Namun gas mampu bakar yang dihasilkan tersebut mengandung tar (kotoran) yang masih tinggi, sehingga terjadi pengotoran filter engine dan mengakibatkan mesin tidak dapat dioperasikan dalam waktu yang cukup lama. Penelitian ini bertujuan untuk mendisain Mesin Pembangkit Listrik Tenaga Biomassa (PLTBm) pada daerah terisolasi dari jaringan listrik PT.PLN (Persero) di Indonesia melalui aplikasi tar wet scrubber dan gas filter. Mesin gasifier yang dirancang berupa tipe downdraft dengan kapasitas terpasang 25 kW. Tambahan komponen rangkaian PLTBm yang dirancang adalah tar wet scrubber, gas filter dan gas engine. Secara keseluruhan mesin PLTBm yang dirancang terdiri dari : (1)Tangki pengisian biomassa, (2)Tangki biomassa, (3)Reaktor tipe downdraft, (4)Cyclon, (5)Tar wet schrubber, (6)Water tank, (7)Gas filter, (8)Blower, (9)Gas engine kapasitas 25 kW, (10)Air inlet nozzle, (11)Connection pipe, (12)Termometer indicator, (13)Exhaust gas, (14)Pressure indicator. Pengurangan nilai tar selain menggunakan karbon aktif, juga menggunakan sistem perangkap kotoran gas (wet scrubber). Gasifier yang digunakan pada penelitian ini memiliki diameter reaktor 900 mm dan tinggi 1000 mm. Cyclon memiliki diameter 580 mm dengan tinggi 1766 mm. Gas filter memiliki panjang 700 mm, tinggi 700 mm dan lebar 700 mm. Tar wet scrubber terdiri dari 5 tabung (diameter tabung 300 mm) yang terangkai satu dengan yang lainnya dengan tujuan untuk menangkap tar yang masih terkandung dalam gas mampu bakar yang dihasilkan dari reaktor gasifikasi dengan dimensi total yaitu lebar 1750 mm dan tinggi 1300 mm.

Co2 Recovery

In this paper thermodynamical and economic analyses of fossil-fuel-fired power plants, equipped with systems for CO2 recovery, are presented. The investigation has been developed with reference to power plants representative both of consolidated technology (i.e., steam cycle and combined cycle power plants), and of emerging or innovative technology (integrated coal gasification combined cycle, IGCC, and advanced mixed cycle, AMC). There are two main methods to reduce CO2 from power plant flue gas: physical and chemical absorption. In this work chemical absorption and liquefaction of CO2 removed have been considered. With reference to thermodynamical and economic performance, significant comparisons have been made between the above introduced reference plants. An efficiency decrease and an increase in the cost of electricity has been obtained when power plants are equipped with CO2 removal systems and units for liquefaction of the removed carbon dioxide. The main results of the performed investigation are quite variable among the different power plants here considered: their efficiency decreases in a range of 6 percentage points to nearly 13, while the electricity production cost increases in a range of 25% until 72%. The AMC stands out among the other power plants here analyzed because, after CO2 recovery, it exhibits the lowest net work output decrease, the highest net efficiency and the lowest final specific CO2 emission. In addition to this, its economic impact is favorable when the AMC is equipped with systems for CO2 recovery. As a result it achieves a net electric efficiency of about 50% with a carbon dioxide emission of about 0.04 kg/kWh, and the electricity production cost rises to about 25% in comparison with an AMC without CO2 removal and liquefaction systems.
