Abstract: The present invention relates to a new use of foaming products for the production of a compact foam pig, by means of the forced interaction of gas, water and product, capable of moving huge quantities of water accumulated in the gas production pipelines. The water removal takes place in very quick periods of time and allows an important decrease in the pressure drops with consequent quick increase in the produced gas quantities.

Abstract: The present invention discloses a fuel composition useful for internal combustion engine having an Octane Number from 95 to 105 comprising: (a) an unleaded and devoid of organometal compounds base gasoline having an Octane Number (RON) from 90.1 to 103: (b) one or more aromatic amines selected in the group consisting of: (b1) 2,4-dialkylaniline, wherein the alkyl groups in position 2 and 4, independently one from the other, are selected in the group consisting of methyl, ethyl, n-propyl, iso-propyl, preferably both the alkyl groups in position 2 and 4 are methyl; (b2) N-Nitrosodiphenylamine. The process for preparing the above composition is also described along with the use of the aromatic amines selected between (b1) and (b2) and related mixtures for increasing the Octane Number.
