Extraction of Cypress Oil and Small-sized Biomass Energy System

According to the trend of needs for renewable or sustainable energy in the world, issues for wind power, solar, and biomass energies have become a large concern among such renewable energies, biomass energy is thought to have a great potentiality. In Kermanshah and east of Lorestan province, prefectural feasibility studies regarding the biomass energy from trees were planned, and were studied However, the wood-based biomass energy system is not economical, and no actual biomass energy projects have started yet in Kermanshah and all of Iran. The income from the biomass energy (electricity and heat) is much lower than the expenditure for purchasing trees and the depreciation for a biomass plant Therefore the items to be discussed here, are : 1) how to achieve the economical system con sidering income and outcome of woodbased biomass energy. 2) how to obtain the efficient biomass system for continuous running operation. The first issue is to find the economical way to obtain some by-products such as ethano1 or sugar. Herein, we have tried to produce cypress oil as a by-product from cypress trees. The second is to find the efficient way for biomass energy production. We selected a spouted bed technique rather than conventional fluidized bed techniques which are widely used far biomass energy production in some Asian countries and the US or Europe. The method was selected so that tar removal can be easy compared to the conventional fluidized bed.
