This paper presents an approach to auctioning long-term gas contracts in Colombia. I propose an annual auction for long-term firm gas contracts. The auction would assign and price all firm gas contracts, with the exception of gas from the Guajira field, which is assigned administratively at a regulated price. The proposal is a partial market design in that it does not address the transportation...

Abstract The present experimental study aims to examine the combustion and emission characteristics of a single cylinder four stroke direct injection diesel engine operated in dual fuel mode using dairy scum oil methyl ester (DiSOME) its blend (B20)—producer gas combination with without addition hydrogen. DiSOME/B20-producer hydrogen exhibited inferior performance increased hydrocarbon carbon m...

Gasification is one of the efficient ways to convert the energy embedded in biomass. Understanding of the effect of a few key parameters such as oxygen enrichment and preheating of air on major design parameters is crucial in designing of a biomass gasifier. In the present study, equilibrium modeling is used to predict the performance of a downdraft gasifier. The composition of producer gas and...

0TUse of lignocellulosic biomass as an alternative, renewable and sustainable source of energy has fulfilled part of the growing demand for energy in developed countries. Amongst various technologies applied to convert biomass wastes to biofuel and bioenergy, biomass gasification has attracted considerable attention. In this work, gasification of palm empty fruit bunch as a potential lignocellu...
