A hydrophilic polymer is used to eliminate humidity from diesel fuel and the regression analysis shows that the maximum decrease of humidity in an hour it is of about ~ 35%.

INTRODUCTION The quality control of alternative liquid fuel aims at finding out if fuel is appropriate so that the decrease in the pollution of the environment can be secured, as well as the right function of combustion engine and the maximum output. One of the most important properties of fuels is the water presence, which is undesirable because it causes corrosion, can cause ice blockage in the power grid that can be formed in low temperatures and last it can be divided during the warming-up and cause flame extinguishing from the produced steam (water vapour). In this paper it is attempted to describe the modification of humidity of diesel fuel via an equation. For this aim we introduce in different samples of diesel fuel the hydrophilic polymer TPA (which has the property to retain water molecules) and its synthesis procedure presented by a suite of software, ChemOffice. The values of humidity is recorded in the modification table by time and with these results is exported the regression equation [1-4] which describes the variation. It is stressed that the volume of the fuel and the mass of the polymer maintain stable. II. EXPERIMENTAL AND STATISTICAL PROCESS A. Synthesis of Hydrophilic Polymer, Thermal Polyaspartate Anion (TPA) [9,10,11,16] The synthesis of polymer is held through the condensation of D,L aspartic acid (1.5g) towards the equivalent polysuccinimide [12] and the hydrolysis of the latter towards the final product of this reaction, the thermal polyaspartate anion (TPA). The selection of aspartic acid as a raw material was supported by the variation of humidity degree that these particle groups show in a water environment. [15] Fig 1. Synthesis of Hydrophilic Polymer, Thermal Polyaspartate Anion (TPA). B. Humidity Elimination of Diesel Fuel via TPA. At first the humidity of Diesel fuels is determined with the method ASTM D-1744 [13] via an automatic potentiometer titrator Karl-Fisher. Next, 0.1 g of TPA is introduced in samples of Diesel 20 mL volume each one. Then, TPA is eliminated through filtration. [14] The values of humidity are recorded every 30 minutes in Table I. K.
