Consulting Services For Gas Based Power Generation

We offer comprehensive consulting services to support the assessment, development, and implementation of renewable energy projects.

Distributed Generation:

Distributed generation is attractive and suitable to your organization because it offers electricity that is more reliable, more efficient, and cheaper than purchasing power from a centralized utility agency. Distributed generation also allows for increased local control over the electricity supply, and cuts down on electricity losses during transmission.

Tri-generation based Technology:

Three benefits in on:- Tri-generation is generally understood to mean the simultaneous conversion of a fuel into three useful energy products: electricity, hot water or steam and chilled water. A tri-generation system is actually a cogeneration system with an absorption chiller that uses some of the heat to produce chilled water. This flexibility to use the recovered heat for heating during one season (winter) and cooling during another season (summer) provides an efficient way of maximizing the running hours at high total plant efficiency, benefiting both the owner and the environment. For example, tri-generation is often used for air conditioning in buildings, for heating during winter and cooling during summer, or for heating in one area and cooling in another area, such as in data centers. Many industrial facilities have such a suitable mix of heating and cooling needs, three examples being hospitals, edible food storage and chemical plants.

Natural Gas- Availability and Utilization:

Natural gas has emerged as the most preferred fuel due to its inherent environmentally benign nature, greater efficiency and cost effectiveness. The demand of natural gas has sharply increased in the last two decades at the global level. In India too, the natural gas sector has gained importance, particularly over the last decade, and is being termed as the Fuel of the 21st Century. Production of natural gas, which was almost negligible at the time of independence, is at present at the level of around 87 million standard cubic meters per day (MMSCMD). The main producers of natural gas are Oil & Natural Gas Corporation Ltd. (ONGC), Oil India Limited (OIL) and JVs of Tapti, Panna-Mukta and Ravva. Under the Production Sharing Contracts, private parties from some of the fields are also producing gas. Government have also offered blocks under New Exploration Licensing Policy (NELP) to private and public sector companies with the right to market gas at market determined prices. Out of the total production of around 87 MMSCMD, after internal consumption, extraction of LPG and unavoidable flaring, around 74 MMSCMD is available for sale to various consumers.

Emissions from the Combustion of Natural Gas:

Natural gas is the cleanest of all the fossil fuels. Composed primarily of methane, the main products of the combustion of natural gas are carbon dioxide and water vapor, the same compounds we exhale when we breathe. Coal and oil are composed of much more complex molecules, with a higher carbon ratio and higher nitrogen and sulfur contents. This means that when combusted, coal and oil release higher levels of harmful emissions, including a higher ratio of carbon emissions, nitrogen oxides (NOx), and sulfur dioxide (SO2). Coal and fuel oil also release ash particles into the environment, substances that do not burn but instead are carried into the atmosphere and contribute to pollution. The combustion of natural gas, on the other hand, releases very small amounts of sulfur dioxide and nitrogen oxides, virtually no ash or particulate matter, and lower levels of carbon dioxide, carbon monoxide, and other reactive hydrocarbons.

What Is Cogeneration?

Cogeneration defines those processes in which useful electric (or mechanical) energy and heat energy are produced simultaneously from fuel. Cogeneration systems are efficient alternatives to traditional mains-energised systems and boilers. Cogeneration is a fully developed technology that is well introduced in the industrial sector. For a few years now, owing to its unquestionable advantages, it has also been successfully used in the service sector.

Cogeneration With Hot Air Production

Cogeneration with hot air production for drying processes is the simpler system, since the elements necessary for heat recovery are basically the same as would be required to cool the engine. This type of cogeneration is usable in processes where hot air is needed for drying purposes, namely in the ceramic industry, lucerne dehydration, manure or sludge dewatering, etc. Heat from the engine liners, in the form of hot water, is converted into hot air in an aircooler. And this hot air is.mixed with the exhaust gases in a chamber. On the controlled mixing process and the correct determination of the amount of air needed by the drying process depends the success of an application in which GUASCOR posses a very extensive experience.

Cogeneration For Air Conditioning- Absorption

Using cogeneration to produce hot water for heating systems is widespread in all of Europe. Since the demand for heating varies according to the seasons, a cogeneration system would not be profitable if heat generated by the cogeneration modules were not used in the summer. In summer, what is really needed is cold water for air conditioning, and this is usually obtained by means of high power-consuming refrigerating compressors. An effective alternative presently consists in using absorption machines (chillers) which are fed with hot water from the cogeneration modules and provide cold water without any draw on electric energy. This makes it possible to get a uniform curve of the cogeneration receiving facilities' heat energy demand and to reduce the electricity bill at the same time. The system is successfully used in air conditioning plants for the tertiary sector as well as in important industrial applications, such as the food, chemical and other industries.

Cogeneration With Hot Water Production

Cogeneration with hot water production probably is the type of cogeneration first put into practice. The so produced hot water can be used as is either as Sanitary Hot Water or in washing, heating or any industrial processes. Its scope of application is very wide, ranging from applications in the tertiary sector, such as hospitals, hotels, sports centre, swimming pools, hypermarkets, etc., to the most complex uses in an industrial environment.

Cogeneratin In Greenhouses

Hot water is produced by recovering almost the total engine heat. Heat from oil and intercooler is used; heat is recovered from the wet liners circuit and the exhaust gases. Due to its great energy utilization rate and contribution to photosynthesis, cogeneration reaches its maximum level of effectiveness when applied to greenhouses. GUASCOR has installed over 300 systems in various greenhouses in Spain and other European countries like the Netherlands, Belgium, Italy, Germany, etc. Natural gas-operated cogeneration modules represent a very profitable investment. New cogeneration laws have changed the framework for their installation very favorably. (RD 43612004). Investments can be rapidly paid back thanks to the possibility of selling up to 90% of the generated electric energy to the electric power system at a good price, the exploitation of heat, and the use of exhaust gases to provide carbon dioxide to plants in the greenhouse. GUASCOR's wide range of modules enables cogeneration patterns to meet the specific requirements of every greenhouse.

Cogeneration At Landfills

Years ago, biogas developing on landfill sites as a result of the organic matter's anaerobic fermentation was extracted by means of a suction system and burnt in flares. Since then, the extraction process has been improved and biogas is now used, once treated, as fuel in GUASCOR cogeneration modules in order to produce electricity and heat. GUASCOR has a great experience in this field and our machines are used in many countries. Most of the electric energy is exported and heat can be used in nearby facilities. Installing biogas cogeneration modules on lanfill sites is very simple and operating them generates economic resources that contribute to defraying the considerable operating costs of controlled landfills.

Cogeneration At Sewage Treatment Plants

Using GUASCOR cogeneration equipment in waste water treatment works is very simple and profitable. Result of the anaerobic fermentation of sludge during the tertiary phase of the sewage treatment process is a methane-rich gas (biogas). Once adequately treated, this biogas is used as fuel in special-purpose GUASCOR cogeneration modules. These produce electric energy for the works and hot water for the digesters. When the process demand for hot water is lower due to climatic conditions, the exhaust gases of the gensets can be used for sluge drying. It is also frequent to use biogas-fuelled engines as direct drivers of agitators.

ADVANTAGES:

There are plenty of advantages offered by cogeneration both to its users and to the society as a whole.

ADVANTAGES FOR THE USER:

Reduction of energy costs, through savings of primary energy and the lower operating cost of a cogeneration plant. Independence from the mains and reliability of supply, since the energy necessary for the industrial processes is self-generated. Size of the cogeneration plant according to the process' energy requirements.

ADVANTAGES FOR THE SOCIETY:

Increased protection of the environment, as emissions are drastically reduced. Improved efficiency of energy generation; electricity and heat generation, transport and distribution cost cut-down, since energy is produced at the place at which it is consumed. Greater balance between the demand and supply of energy, which results in the reduction and stability of the energy prices.
