摘要

Crude vegetable oil energy conversion is addressed as an important issue for the electric energy production without changing the CO_2 concentration in atmosphere. The oil is obtained by grinding oily fruits while a high amount of energy rich residues is produced. The present paper evaluates the thermodynamic and environmental performances of a plant that converts the whole fruit into energy through pyrolysis. Vegetable Oil is used to fuel an internal combustion engine while solid residuals of the oil production are used to fuel an Integrated Pyrolysis Regenerated Plant (IPRP) technology based plant. Tars from pyrolysis process are water scrubbed from syngas and then emulsioned with vegetable oil to increase the electric energy production. IPRP concept is based on a gas turbine (GT) fuelled with the syngas produced in a rotary kiln pyrolyzer fed with Biomass or Wastes (B&W); GT exhaust gases together with combustion of pyrolysis by-products (char), is used to sustain the pyrolysis process. The IPRP concept was modelled through thermodynamic relations, energy balances and data available in the Literature for oil yields and husks pyrolysis products. The analysis was carried out investigating the influence on plant performances of main thermodynamic parameters of the GT and on pyrolysis temperature. Results are collected for typical parameters of different GT sizes, namely the manometric compression ratio and the turbine inlet temperature. The paper discusses best efficiency points of different plant sizes when fuelled with syngas and tar and oil for three important oil fruits namely sunflower, palm and soybean.
