A process for treating a petroleum fraction and for efficiently absorbing an organic halogen compound from a fluid mixture of the organic halogen compound and an inorganic halogen compound derived from crude oil. Also disclosed is an improvement in absorption performance of a halogen-compound-absorbing material, thereby reducing the frequency with which the absorbing material is exchanged. The absorbing agent includes attapulgite (palygorskite) having high absorption performance with respect to organic halogen compounds. Also disclosed is an absorption column in which the aforementioned absorbing agent and a halogen-compound-absorbing agent, that includes zinc oxide, are disposed in series, thereby making it possible to raise the treatment performance with respect to a fluid that contains, in high concentrations, the organic halogen compound in addition to the inorganic halogen compound.

The present invention provides a novel method for treating soil-contaminated water, the method using a photocatalytic material capable of efficiently removing, by light irradiation alone, volatile organic compounds and heavy metals that give rise to soil contamination. The present invention provides a method for treating soil-contaminated water that detoxifies volatile organic compounds contained in soil-contaminated water using a photocatalytic material, the method being characterized by including the steps of (1) subjecting the soil-contaminated water to a gas-liquid separation to obtain a gas phase, and (2) decomposing the volatile organic compounds contained in the gas phase obtained in step (1) using the photocatalytic material. The present invention further provides a method for treating soil-contaminated water using a photocatalytic material to remove heavy metals contained in the soil-contaminated water, the method being characterized, by including the steps of (1) subjecting the soil-contaminated water to a gas-liquid separation to obtain a liquid phase, and (2) removing the heavy metals contained in the liquid phase obtained in step (1) using the photocatalytic material.

Materials and methods for mitigating the effects of halide species contained in process streams are provided. A halide-containing process stream can be contacted with mitigation materials comprising active metal oxides and a non-acidic high surface area carrier combined with a solid, porous substrate. The halide species in the process stream can be reacted with the mitigation material to produce neutralized halide salts and a process stream that is essentially halide-free. The neutralized salts can be attracted and retained on the solid, porous substrate.
