THE USE OF BIOGAS GENERATED FROM SWINE MANURE AS A PRELIMINAR AGENT IN THE VIABILIZATION OF BIOGAS PIPELINE CONSTRUCTION

摘要

Santa Catarina state has over 800 km of natural gas distributed along the coast line, however, has an area of 95.700km~2. Due to mountainous relief, constructing pipeline that will supply natural gas to remote areas will prove difficult. Supplying gas to remote areas through biogas from pig manure is a feasible alternative to building a gas pipeline to these regions. Using data from the IBGE and by aid of computer programs it was found that Santa Catarina has a potential to generate biogas from 900.000 m~3 / day which are located predominantly in the western region of state. Thus, through the provision of biogas in this region a market that uses natural gas as an energy source can stimulate. As result the pay-back time and the feasibility risk of a network gas project can be reduced. It was found that only in the west there is an energy potential to be shifted to natural gas equivalent of 389.583 m~3 / day and as expected output is estimated to reach 16.728 m~3 / day. This helps anticipate the building of a natural gas network that links the coast with outskirts of the state, while the environmental impact of swine as methane emissions and waste are reduced.
