The utilization of vegetable oils, and in particular the palm oil, as fuel in the power generation has had a remarkable development in the last few years. Generally the vegetable oil can be used with a particular marine-derived diesel ICE, with low rpm and an electric conversion efficiency of about 40%. The efficiency is strictly connected to the s...

... manufacturer indicates a detailed list of the vegetable oil to be used in diesel ICE. The Table 4 below shows, as an example, the detailed list of the oil used in diesel ice manufactured by MAN Diesel & Turbo leader in this engineering field. This value, according to the above-mentioned legislation, allows the palm oil with these characteristics to be used in actual commercial diesel oil ICE. ...

... In many experimental applications, refined vegetable oils, oil-diesel blends, biodiesel and diesel-biodiesel blends are used, while SVO is not frequently used and, therefore, research and experimentation are still required. Moreover, most of the studies are related to Internal Combustion Reciprocating Piston Engines (ICRPEs) [5][6][7]. Therefore, there is still a lack of technical literature and field experience on MGTs fed by straight vegetable oil. In fact, the only experiences on MGTs fed by vegetable oil are mainly related to biodiesel [8][9][10][11][12][13]. ...
This paper deals with the technical feasibility of the use of straight vegetable oil (SVO) as gas turbine fuels.
First, this paper reports the results of the experimental characterization of different vegetable oils, derived from energy crops, and of blends of diesel and vegetable oil in different concentrations (from pure diesel to pure vegetable oil). The considered vegetable oils were obtained from different types of oilseeds (rapeseed, sunflower, soybean) and were cultivated under different agronomic scenarios. The SVO properties determined experimentally are SVO elemental composition, lower heating value, density, specific heat and viscosity, for which this paper provides a practical overview, coming both from experiments and literature data.
Secondly, the paper experimentally evaluates the behavior of a Solar T-62T-32 micro gas turbine fed by vegetable oils. The vegetable oils are supplied to the micro gas turbine as blends of diesel and straight vegetable oils in different concentrations, up to pure vegetable oil. The paper describes the test rig used for the experimental activity and reports some experimental results, which highlight the effects of the different fuels on micro gas turbine performance and pollutant emissions.
... InTable 8 are reported these considerations. As to management cost fuel supply, ordinary maintenance, and electricity distribution were considered [3]. The system revenues were associated to the sale of electric power and the sale of Green Certificates (GC). ...
Nowadays the utilization of vegetable oils, particularly the palm oil, as fuel in the power plant, has made a significant development in the last few years. This vegetable oil can be used in particular in slow marine-derived diesel internal combustion engine (ICE), with an electric efficiency of about 40%. The efficiency is connected to the size of the power plant. Moreover, the considerable amount of the required vegetable oil to feed the system forces, especially in Italy, makes it necessary to import the fuel. This is the most critical element as the palm oil is subject to continuous variations in prices. Due to this variation it is difficult to stabilize a convenient fuel supply for a long period. The paper aims to evaluate and estimate the economic, technical and environmental feasibility of a 20 MW plant for the stationary power generation fed with palm oil, enlightening the system solution (technical constructive aspects) and the economic appraisal, on the basis of variations in oil prices. A comparison with a cogenerative power plant has been also carried out and, at last, the economic sensibility analysis based on the fuel cost and the European mechanisms of biomass incentives is performed.
... In this field, experiences are carried out by ERRSA Energietechnik in Germany [11], which offers CHP stations composed of ICRPEs fuelled by vegetable oils, or by Bios Bioenergiesysteme [12], which has developed a CHP plant based on vegetable oil fired ICRPEs and Organic Rankine Cycle (ORC) modules. More recently, Calabria et al. evaluated the economic, technical and environmental feasibility of a 20 MW plant for the stationary power generation fed with palm oil, enlightening technical constructive aspects and the economic appraisal [13]. ...
The application of bio-fuels in automotive, power generation and heating applications is constantly increasing. However, the use of straight vegetable oil (pure or blended with diesel) to feed a gas turbine for electric power generation still requires experimental effort, due to the very high viscosity of straight vegetable oils.
In this paper, the behavior of a Solar T-62T-32 micro gas turbine fed by vegetable oils is investigated experimentally. The vegetable oils are supplied to the micro gas turbine as blends of diesel and straight vegetable oils in different concentrations, up to pure vegetable oil.
This paper describes the test rig used for the experimental activity and reports some experimental results, which highlight the effects of the different fuels on micro gas turbine performance and pollutant emissions. Moreover, an identification model is set up to predict the behavior of the considered gas turbine, when fuelled by vegetable oil, and the sensitivity of micro gas turbine thermodynamic measurements and emissions is quantitatively established.
When water based muds fail to ensure that a usable hole is drilled, oil based mud formulated with No.2 diesel is adopted. Because No. 2 diesel is toxic, the oil and gas industry is looking for other alternatives to it. One of such alternatives is the use of vegetable oils. These vegetable oils are relatively more expensive than the No. 2 diesel; hence their use would ultimately increase the cost of drilling fluids. There are however many types of these vegetable oils. These vegetable oils vary in physical and chemical properties and in their cost. This paper undertook an investigation into the cost, properties and availability of these vegetable oils for use in drilling mud formulation; it chronicled the trend of researches available on the use of vegetable oils as drilling fluids with the findings from each researcher presented. This paper also presents a detailed cost benefit analysis of major vegetable oils used as drilling muds. To make the work comprehensive, an evaluation of the viability of each vegetable oil to achieve the objectives of cost effectiveness, availability, and good rheological and filtration properties were evaluated. The results showed that of all the vegetable oils studied, olive oil ranked the least in meeting all of these objectives while palm oil, soybean oil followed by rapeseed oil fulfilled all of the objectives to a considerable extent. This paper therefore offers an all-inclusive portfolio of cost related issues that border on the use of vegetable oils as drilling muds which would be useful to wellbore drillers in particular and the E & P industry at large.
