A process for the extraction of lipids from algal biomass comprising: &#x2014;producing an aqueous suspension of algal biomass; &#x2014;adding to said aqueous suspension of algal biomass at least one organic solvent immiscible or substantially immiscible with water obtaining an organic-aqueous mixture; &#x2014;subjecting said organic-aqueous mixture to evaporation of water and lipid extraction, operating at a temperature such to obtain the substantial complete removal of the water from said organic-aqueous mixture, obtaining: (i) an organic phase comprising lipids and said organic solvent; (ii) a semi-solid phase comprising a residue of said algal biomass.

Process for the extraction of lipids from algal biomass

Process for the extraction of fatty acids from algal biomass comprising: producing an aqueous suspension of algal biomass; subjecting the aqueous suspension of algal biomass to acid hydrolysis and extraction by the addition of at least one non-polar organic solvent and at least one inorganic acid to said aqueous suspension of algal biomass, so as to obtain the following three phases: (i) a semisolid phase comprising a slurry of the algal biomass; (ii) an aqueous phase comprising inorganic compounds and hydrophilic organic compounds; (iii) an organic phase comprising fatty acids and hydrophobic organic compounds other than said fatty acids.

Process for the extraction of fatty acids from algal biomass

An improved process is described for the removal of organic pollutants from soil by extraction with a lipophylic solvent, wherein the improvement consists in the fact that the purified soil is treated with water to remove the residual solvent. This process allows the residual solvent to be completely removed from the purified soil enabling it to be re-inserted into the environment, with a low energy consumption and a greater guarante of safety in the running of the plant.

Process for the remediation of soil polluted by organic compounds

Process for the photocatalytic purification of waste water contaminated by odorant compounds containing sulfur, which can be applied to the purification of condensed water collected along the gas distribution network for domestic and industrial use.
