Representative Model

This research is based on obtaining a mathematical model to determine the efficiency of generating a generator coupled to a biomass gasification process. To do this, it is initially simulated internal combustion engine at the Aspen hysys® licensed software, in order to obtain the shaft work and a representative model of the generation efficiency of the motor; according to the characteristics of the power cycle and product gas from the gasification of agricultural biomass prevailing in the Department of Córdoba – Colombia: Cotton waste (Gossypium hirsutum), Rice husk (Oryza sativa), Sesame stalk (Sesamum indicum), Corn cob (Zea mays) and Coconut fiber (Cocos nucifera). Subsequently, the generator efficiency is evaluated by the electric power generation simulation phase in the Simulink Toolbox of the MATLAB® software. The deterministic mathematical models resulting from the simulations above are adjusted by statistical techniques to experimental data and a regression model that assesses the overall system efficiency is obtained. Such efficiencies range from 16 to 20%. Therefore it is concluded that the use of representative crops biomass product’s calorific values in the Department of Córdoba -Colombia, are profitable for electric power generation. On the other hand, it is important to note that experimental data’s reliable and monitored way acquisition was performed through the SCADA developing; it allowed real time process variables’ intervention presentation.

 The accuracy in measuring the physical properties of any crude oil has become a very difficult task because the price of crude oil in the global market depends on it in addition to the process of producing lubricating oil , chemical products and refinery. Accordingly, this research effort focuses on comparative study of Libyan crude oil (El-Wafa field)  by measuring the physical and some chemical  properties  experimentally and by Aspen HYSYS V8.4 programs. Also, test the possibility to know the volume percentage of the production of lubricants from this crude oil by the two methods mentioned above.Test carried out on these measurements practically and theoretically the physical properties are include: normal boiling point, pour point, Specific gravity (Sp. gr.), standard density (API), dynamic viscosity , kinematics viscosity , molecular weight, Acentric factor and Watson factor (K or Kw ). Some chemical properties have also been experimentally measured, for example the sulphur content ( wt.%), Asphaltenes content( wt.%)  , water and sediment content (vol.%), Conradson carbon residue ( wt.%) , salt content (as NaCl, mg\L),  ash content(wt. %) and metals content ( wt.%).The results from the tests showed that, there is a very small convergence between the results of calculations of physical properties by use this modern software with experimental measurements in the lab to the crude oil of El-Wafal field up to 99% and this blend is not suitable for production the lubricated oil at atmospheric distillation column. Also, the results observed that’s the useful mole percentage of lubricated oil cutoff has volume percentage range not significant from 1 to 1.8% for this type of Libyan crude oil. Through practical and theoretical results possible to classify this type of crude oil as Brent mix according to the global market for the sale of crude oil, which is characterized by its lack of sulfur element and metals in addition to its standard relative density API is very high more than 55.

Biomass gasification in one of the modern technology that was developed by thermochemical conversion. This technology has been developed in many countries. This paper gives an emphasis on developments and trends in the use of gasification technology in some countries (Finland, Denmark, Thailand, Sri Lanka, Cambodia), and learning for Indonesia as well. At least there are five things that could be the key to the success of implementation, namely the ongoing and continuous research and development, the involvement of all actors in research and development activities, the implementation focuses on a small scale first, the roadmap plans into the action with a strong financial support, and the human resources support at national and local levels.Gasifikasi biomassa merupakan salah satu teknologi modern yang dikembangkan melalui konversi termo kimia. Teknologi ini telah banyak dikembangkan di berbagai negara. Makalah ini memberikan penekanan pada perkembangan dan kecenderungan penggunaan teknologi gasifikasi di beberapa negara (Finlandia, Denmark, Thailand, Sri Langka, Kamboja), dan pembelajaran bagi Indonesia. Setidaknya ada lima hal yang dapat menjadi kunci keberhasilan implementasi, yaitu riset dan pengembangan berkelanjutan dan berkesinambungan, pelibatan semua aktor dalam aktivitas riset dan pengembangan, implementasi pada skala kecil dahulu, perencanaan peta jalan hingga aksi dengan dukungan pendanaan yang kuat, dan dukungan sumber daya manusia di tingkat nasional dan lokal.Keywords: biomass gasification, technology trends,comparative study.
