Abstract: A steam reformer generates reformed gas by a steam-reforming reaction of hydrocarbon gas such as natural gas. A methanol synthesis column and a gasoline synthesis column synthesize gasoline from the reformed gas via methanol and produce a liquid fuel. A superheater superheats a part of low-pressure steam that has been heat-recovered from the reformed gas with a part of middle-pressure steam that has been heat-recovered by the methanol synthesis column or the gasoline synthesis column, and the steam thereby brought into an unsaturated state is supplied to a low-pressure steam turbine.

Abstract: In a water treatment system (1) and a water treatment process, a scale inhibitor is supplied to water to be treated containing Ca ions, SO4 ions, carbonate ions, and silica, and the water to be treated is adjusted to a pH at which silica is soluble. The pH-adjusted water to be treated containing the calcium scale inhibitor is separated in a demineralizing section (10) into concentrated water and treated water. In a crystallizing section (20), seed crystals of gypsum are supplied to the concentrated water, whereby gypsum is crystallized and removed. Silica in the water to be treated is removed from the concentrated water on the downstream side of the crystallizing section (20). Calcium carbonate in the water to be treated is removed from the concentrated water on the upstream side of the demineralizing section (10) or the downstream side of the crystallizing section (20).

Abstract: A system and method for separating CO2 from natural gas, which ensure that no clogging or deterioration occurs in a gas separation membrane even after the gas separation membrane is used to remove carbon dioxide from the natural gas under conditions in which the natural gas is pressurized. First, an H2S remover removes hydrogen sulfide from raw natural gas. Then, a compressor pressurizes the natural gas from which H2S has been removed. After that, a cooler cools the pressurized natural gas so as to condense components that are a part of the natural gas. A gas/liquid separator removes the condensed components, and a CO2 separator, including a separation membrane for separating CO2 removes CO2 from the natural gas from which the condensed components have been removed. An expander, which shares a drive shaft with the compressor, expands the natural gas from which CO2 has been removed and recovers energy therefrom.
