Abstract: Disclosed herein is a method for simply treating produced water extracted in large quantity while suppressing an increase in cost due to the use of a chemical agent and the associated generation of waste. The method is a method for treating produced water extracted in association with crude oil production or natural gas production and containing at least oil as a substance to be treated including: an oil separating step 1 optionally performed to remove free oil or the like from the produced water; a flocculation step 2 in which emulsified oil is flocculated by introducing micronanobubbles composed of an ozone-containing gas into the produced water so that a gas-liquid contact time of 2 to 60 minutes is preferably achieved; and a flotation step 3 in which the flocculated emulsified oil is separated as scum by flotation to obtain clarified water.

Abstract: By using the power generated by an expander by an expansion of material gas, the outlet pressure of a compressor is increased, and a requirement on the cooling capacity of a cooler is reduced. The liquefaction system (1) for natural gas comprises a first expander (3) for generating power by using natural gas under pressure as material gas; a first cooling unit (11, 12) for cooling the material gas depressurized by expansion in the first expander; a distillation unit (15) for reducing or eliminating a heavy component in the material gas by distilling the material gas cooled by the first cooling unit; a first compressor (4) for compressing the material gas from which the heavy component was reduced or eliminated by the distillation unit by using power generated in the first expander; and a liquefaction unit (21) for liquefying the material gas compressed by the first compressor by exchanging heat with a refrigerant.

Abstract: The invention provides a treatment process of a gas containing zero-valent mercury and a mercury separation system, by which the amount of an iodine compound used can be reduced when the zero-valent mercury is separated from the gas containing the zero-valent mercury by using the iodine compound. The treatment process of the gas containing the zero-valent mercury has a mercury oxidation step of oxidizing the zero-valent mercury contained in the gas containing the zero-valent mercury with a first liquid phase containing an alkali metal iodide to take the zero-valent mercury into the first liquid phase, thereby obtaining a second liquid phase containing a divalent mercury ion and an iodide ion; a mercury separation step of separating the divalent mercury ion as mercury sulfide by adjusting the pH of the second liquid phase obtained in the mercury oxidation step with a pH adjustor and adding an alkali metal sulfide; and a first circulation step of circulating a third liquid phase which is obtained by separating the mercury sulfide in the mercury separation step and contains an alkali metal ion and the iodide ion to use the third liquid phase as the first liquid phase in the mercury oxidation step.

Abstract: A method for producing monocyclic aromatic hydrocarbons includes a cracking/reforming reaction step of introducing the feedstock oil into a cracking/reforming reactor, bringing the feedstock oil into contact with the catalyst, and causing the feedstock oil to react, thereby obtaining a product, a purification/recovery step of purifying and recovering the monocyclic aromatic hydrocarbons separated from the product produced in the cracking/reforming reaction step, a hydrogenation reaction step of hydrogenating a heavy fraction separated from the product produced in the cracking/reforming reaction step, and a recycling step of returning a hydrogenation reactant of the heavy fraction obtained in the hydrogenation reaction step to the cracking/reforming reaction step. In the recycling step, the hydrogenation reactant of the heavy fraction is introduced at a location different from an introduction location of the feedstock oil into the cracking/reforming reactor so that a time during which the hydrogenation reactant of the heavy fraction is in contact with the catalyst for monocyclic aromatic hydrocarbon production in the cracking/reforming reactor becomes shorter than a time during which the feedstock oil is in contact with the catalyst for monocyclic aromatic hydrocarbon production in the cracking/reforming reactor.

Abstract: A carbon-based catalyst for flue gas desulfurization is brought into contact with a flue gas containing at least SO 2 gas, oxygen and water vapor so that the SO 2 gas can react with the oxygen and the water vapor to form sulfuric acid which is to be recovered. On a surface of the carbon-based catalyst, iodine, bromine or a compound thereof is added, ion exchanged or supported and a water-repellent treatment is applied. The carbon-based catalyst can also be used as a mercury adsorbent for flue gas treatment for adsorbing and removing metallic mercury from a flue gas containing metallic mercury, SO 2 gas, oxygen and water vapor.
