Abstract: Provided are a non-hydrocarbon gas separation device and the like capable of increasing a discharge pressure of a non-hydrocarbon gas to a downstream side while preventing an increase in size of equipment. In the non-hydrocarbon gas separation device, a first separation module (2a) and a second separation module (2b) connected to each other in series are each configured to separate a non-hydrocarbon from a natural gas through use of a separation membrane (20).

At this time, a pressure of the first separation module (2a) on a discharge line (202) side is higher than a pressure of the second separation module (2b) on a discharge line (204) or (202) side.

Abstract: A process for producing a carbonic acid diester, which comprises carrying out a reaction in a vapor phase of an alcohol, carbon monoxide and oxygen in the presence of a catalyst in a fluidized-bed reactor so that an oxidative carbonylation of the alcohol occurs, thereby obtaining a carbonic acid diester, wherein a heat of reaction is removed by the latent heat of vaporization of the alcohol as a raw material. In the process, for example, either at least part of the alcohol may be directly fed in liquid phase into the fluidized bed or cooling pipes are disposed in the fluidized bed and at least part of the alcohol is introduced in liquid phase into the cooling pipes as a heat transfer medium so that the liquid alcohol is vaporized and fed into the fluidized-bed reactor. Carbon monoxide may be introduced together with the liquid alcohol into the cooling pipes.

Abstract: In a crystallization method, a liquid mixture containing a crystallizable component is cooled so as to form and separate crystals of the crystallizable component. Then, a purified melt having purity substantially equal to that of the separated crystals, to which a polymerization inhibitor is added and which is heated to a temperature higher than a freezing point of the separated crystals, is circulated to flow contacting the crystals so as to accelerate melting. Then, the melted crystals are recovered along with the purified melt containing the polymerization inhibitor.

Abstract: Crystallization method and crystallization apparatus each use vertical plates for crystallization thereon. Both surfaces of the plate are used for different two liquids to flow down as films. Specifically, on one vertical surface, a feed liquid mixture containing crystallizable components therein flows down as a film, and on an opposite vertical surface, a cooling medium flows down as a film. Accordingly, the crystallizable component contained in the feed liquid mixture is cooled and crystallized to form crystal layers on the one vertical surface of the plate. The formed crystal layers are melted by a heating medium which flows down on the opposite vertical surface, and are collected as a melt. A pair of the plates may be used to form a unit to purify the liquid mixture on a large scale. A number of the units may be used to form a block which is suitable for a larger-scale crystallization processing.

Abstract: In a non-agitational, countercurrent flow type of liquid-liquid contacting tower, splitter plates with plural slits and/or holes through which light and heavy liquids flow, and baffles having the appropriate shapes and areas in order to cover the liquid flowing upward or downward, are alternately mounted horizontally inside the tower shell in vertical direction. The ratios of the opening area to the total cross-sectional area in the splitter plate are 10% to 40%, and the opening area of a baffles is larger than the aperture area of a splitter plate. The advantages of this invention are as follows: Because of the high contacting efficiency, a relatively smaller contactor has an equivalent performance with that of a larger contactor; there exists no risk of plugging due to scum accumulation, and maintenance is easy.

Abstract: A feed liquid (sugar-containing liquid) is continuously fed to a fermenter packed with an immobilized microorganism, which is obtained by immobilizing an alcohol producing microorganism on a carrier, for alcohol fermentation. The fermentation liquid is continuously taken out of said fermenter and is heated to a temperature of 35.degree. to 80.degree. C. This liquid is introduced into a flash tank maintained at reduced pressure and is divided into an alcohol-containing steam and a liquid. The alcohol-containing steam is condensed and recovered as alcohol, while the separated liquid is cooled and is cycled back to said fermenter.

Abstract: An apparatus for automatically causing a workpiece to engage a rotary tool. A pulse signal generated by rotating a reference workpiece is stored, and then a pulse signal generated by rotating a mounted workpiece is counted. The counted pulse signal and the stored pulse signal are compared, and when they coincide with each other, the workpiece is brought into engagement with the rotary tool. When the rotary tool is shifted, the stored pulse signal information is updated, and then a pulse signal generated by rotating a mounted workpiece is counted. If the updated stored pulse signal information land the counted pulse signal information are equal to each other, then the workpiece is taken into engagement with the rotary tool.
