Remoção do óleo da água produzida por flotação em coluna usando tensoativos de origem vegetal

Abstract

The treatment of the produced water and his implications are continuously studied and several inquiries are directed to this area. In our region, the Petrobras’ sites of the UN-RNCE, the reservoirs ONSHORE are in his majority ripe wells, with production of water in the belt of 90 %, some cases up to 100 %, however this AP cannot be discarded simply. Besides being a risk to the environment for the contamination of the ground, groundwater or even animals and plants, as well as in the bodies of water in the platforms, OFFSHORE, there are Laws, National Standards and Organs what they regulate and supervise it discard of this produced water, principally for the presence of hydrocarbons, salts and heavy metal. At present it are used polyelectrolytes what make easy the coalescence of the drops of oil, like coagulants agents, but besides not being biodegradable, are expensive when the process is getting dearer. This work has how I aim to propose a process of flotation in column using surfactants ionic vegetable origin in substitution of the polyelectrolytes as well as getting an experimental correlation that represents the obtained results. Before the analyses of the concentration of the oil in the water the efficiency of removal was brought near of 100 % and the obtained equation of the model adjusted well the experimental data.
