Title (EN) GAS STORAGE METHOD AND PRODUCT
(FR) PROCEDE ET PRODUIT DE STOCKAGE DU GAZ
Abstract:
(EN) For storage of natural gas at pressures over 1,000 psia, it is advantageous to add to natural gas an additive which is a C2 or C3 hydrocarbon compound, or a mixture of such hydrocarbon compounds. Above a lower limit (which varies with the additive being added and the pressure), a decrease in the amount of power is needed to compress the mixture. For storage or pipeline transportation of natural gas at pressures over 800 psia, it is advantageous to add ammonia to the natural gas, in an amount such that the ammonia does not create a liquid phase at the temperature and pressure used. The ammonia-natural gas mixture can be compressed or pumped with a lower energy expenditure than would be needed for an equivalent volume of natural gas alone. When more than 4 % by volume of ammonia is present, the pumping through pipelines is also aided by the refrigerant effect of the ammonia, which reduces the temperature of the gas being transported. Instead of ammonia, hydrogen fluoride or carbon monoxide can be added to the natural gas, but these are less preferred than ammonia.
(FR) Pour le stockage du gaz naturel à des pressions supérieures à 1000 lb/po2, il est avantageux d'ajouter au gaz un additif qui est un composé à base d'hydrocarbures C2-C3 ou un mélange de composés de ce type. Au-dessus d'une limite inférieure (qui varie en fonction de l'additif ajouté et de la pression), on obtient ainsi une diminution de la puissance nécessaire pour comprimer le mélange. Pour le stockage ou le transport par pipeline du gaz naturel à des pressions supérieures à 800 lb/po2, il est avantageux d'ajouter au gaz de l'ammoniac, en une quantité telle que ce dernier ne génère pas de phase liquide à la température et à la pression utilisées. Le mélange ammoniac-gaz naturel peut être comprimé ou pompé avec une consommation d'énergie inférieure à celle qui serait nécessaire pour un volume équivalent de gaz naturel seul. Quand la quantité d'ammoniac présent est supérieure à 4 % en volume, le pompage par pipeline est également facilité par l'effet réfrigérant de l'ammoniac, qui diminue la température du gaz transporté. A la place de l'ammoniac, on peut ajouter au gaz naturel du fluorure d'hydrogène ou du monoxyde de carbone, mais ceux-ci sont moins préférés que l'ammoniac.
