Abstract
The use of LNG for the production of additional energy is topical today. Very often LNG is used for gasification of settlements and industrial enterprises. LNG makes it possible to gasify objects remote from main pipelines for long distances by creating an LNG reserve directly from the consumer, avoiding the construction of expensive piping systems. However, in this case, there are large losses of cryoproduct and its low-potential heat. In this article, we propose a technical solution for compensating for the loss of cryoproducts during storage using an installation consisting of two circuits, one of which is a loss compensation loop and the other is a circuit for generating additional energy. The conducted researches showed that the use of this system allowed to return the previously used for liquefying electric power in the amount of 24%.
Highlights
At present, natural gas is becoming one of the most important sources of energy, as its reserves are huge, and it is environmentally friendly fuel in comparison with petroleum products
The most relevant at the moment is the use of liquefied natural gas (LNG) as an energy carrier for the same purposes as conventional natural gas, since this allows to reduce the mass-dimensional characteristics of tanks for storage and transportation [1]
Liquefied natural gas contains an energy potential that could be used to return it to its original gaseous state, and the very process of LNG reagation has a significant potential for energy saving [4]
Summary
Natural gas is becoming one of the most important sources of energy, as its reserves are huge, and it is environmentally friendly fuel in comparison with petroleum products. Liquefied natural gas (like any other cryoproduct) contains an energy potential that could be used to return it to its original gaseous state, and the very process of LNG reagation has a significant potential for energy saving [4]. This energy is called cold energy and there are a lot of science work in field of its using. When supplying LNG to the gas distribution point and through the local highways networks to residential houses, industrial enterprises and for refueling vehicles at the gas station, a regasification process in the evaporator is usually carried out, usually atmospheric type (Figure 1). The waiting time for the remaining LNG storage options, which is presented in Table 2, has been calculated
