摘要： PURPOSE:To obtain the titled apparatus, having a feeding means for distillation column waste water discharged in distilling crude methanol and feeding means for air, filled with packings therein and capable of decomposing formic acid an in the above-mentioned waste water with oxygen and preventing corrosion of humidifier constituent materials. CONSTITUTION:Waste water from a distillation column discharged in distilling crude methanol in the distillation column is utilized as makeup water for a humidifier used in humidifying natural gas for steam reforming in a methanol synthesis plant. In the process, an apparatus 1 for producing the above-mentioned makeup water, having a feeding means 5 for the afore-mentioned waste waster and a feeding means 6 for air and filled with packings, preferably a catalyst material 2 for decomposing formic acid therein is used to oxidatively decompose and remove strong corrosive formic acid present in the above-mentioned waste water as a product of side reaction of methanol synthesis with oxygen in in expensive air. Thereby corrosion of humidifier constituent materials by the formic acid in the afore-mentioned waste water is reduced.

摘要： PROBLEM TO BE SOLVED: To obtain the subject composition, useful as a substitute material for an inorganic lining material or a metallic material and capable of providing a coating film excellent in heat, acid and oil resistances by compounding a specific binder with a flake. SOLUTION: This composition is composed of a binder comprising (A) a silicone-modified epoxy resin and (B) an aminosilane-based coupling agent which is a curing agent therefor, (C) a flaky stainless powder, (D) an organic solvent and, as necessary, (E) a pigment and (F) various additives. The preferred compounding ratios of the respective components based on 100 pts.wt. component A in the coating film-forming component (solid content) are preferably 0.5-20 pts.wt. component B, 5-20 pts.wt. component C and 0-100 pts.wt. component E. Since the composition is capable of forming a coating film having excellent heat, acid and oil resistances and adhesion, the composition is thereby suitable for a coating material for inner surfaces of a chimney and a flue of various thermal power plants such as coal fired and LNG fired ones and capable of further prolonging the useful life of the inner surfaces of the chimney and flue.

摘要： PURPOSE:To make it possible to apply a polypropylene lining in a very simple manner by first, spraying polypropylene powder over the inner surface of a carbon steel pipe which is heated and thus melting the powder, and cooling the molten polypropylene to become hardened after sealing a pressurized gas into the pipe. CONSTITUTION:For example, first the inner surface of carbon steel pipe with an internal diameter of 4'' and a length of 200mm is cleaned by blast process, then this pipe is heated at 250+ or -20 deg.C, and, for example, polypropylene powder with an average grain diameter of 100mum is sprayed so that the thickness of a lining is 2mm. In addition, the powder is thermally molten, flanges 2, 2 and a pressurized gas feed pipe 3 are installed on both ends of the pipe 1, and further, for example, nitrogen gas is pressurized and sealed into the pipe 1 at a specified pressure. Thus the powder is cooled to become hardened and thereby the carbon steel pipe lined with polypropylene is prepared. Consequently, the contraction and stress concentration of polypropylene during the cooling/ hardening process, are moderated by sealing the pressurized gas into the pipe, so that the generated polypropylene lining can be prevented from peeling off.

摘要： PURPOSE:To produce a PP lining material in sheet or stick form which can be applied on a metallic material in a high-temperature region and is excellent in adhesiveness, by using a resin composition obtained by incorporating a specified rubber and an antioxidant into a mixture of a maleic acid modified PP and a PP at a specified ratio. CONSTITUTION:A mixture of maleic acid modified PP and a PP at a weight ratio of (10:1) to (1:100) is mixed with 1-20wt.% ethylene/propylene rubber and then with 0.1-1.0wt.% antioxidant {e.g. pentaerythrityl-tetrakis[3-(3,5-di-t-butyl-4- hydroxyphenyl) propionate]} to give the title composition. A lining material in sheet or stick form is made from this composition.

摘要： PURPOSE:To enable formation of excellent polyethylene lining even in a high- temp. environment by degreasing the surface of a material to be lined, washing with water, pickling with hydrochloric acid, washing with water, dipping in a specified boiled soln. to form a specified film, washing with water, dipping in a specified chromate soln., and then drying. CONSTITUTION:The lining method of powdery polyethylene includes the following process. A material to be lined consisting of carbon steel is preheated at temp. higher than the melting point. The powdery polyethylene is molten by the heat of the material to form a continuous polyethylene film on the surface of the material to be lined. As for the base treatment of the material to be lined, the surface of the material is degreased, washed with water, washed with hydrochloric acid, washed with water, and dipped in a boiled soln. comprising caustic soda, sodium orthophosphate and sodium nitrite to form a film essentially comprising Fe3O4 on the surface. Then the surface is washed with water, dipped in a chromate soln. of pH 4.5-6.0 having 0.005-0.05wt.% CrO3 concn., and dried.

摘要： PURPOSE:To surely prevent the crevice corrosion of a stainless steel pipeline flange surface by coating the joining surfaces of the flanges with a coating material having a softening temp. lower than the temp. of an aq. soln. in the pipeline. CONSTITUTION:The joining surfaces of a stainless steel flange in various plants are coated with a coating material. The coating material should have a softening temp. lower than the temp. of an aq. soln. contg. corrosives flowing in the pipeline by 20 deg.C. A packing is then placed between the flanges, and the flanges are held to each other by tightening bolts, and the pipelines are joined. The coating material is softened in operation and moved to fill the gap between the flanges, and the coating on the flange surface and the packing are completely integrated. As a result, the pipelines are joined without any gap, the crevice corrosion is not caused, and devices and pipelines are constructed at a low cost.

摘要： PURPOSE:To regenerate ethanol and to remove the surfactant and water deposited on a product to be cleaned in the degreasing and cleaning using an aq. soln. of surfactant. CONSTITUTION:A product is degreased and cleaned by an aq. soln. of surfactant, rinsed with water and dipped in ethanol to remove the deposited surfactant and water. In this case, a mixed soln. of the ethanol, water and surfactant is continuously withdrawn, the mixed soln. is separated in a distillation tower into a mixed soln. of ethanol and water and a mixed soln. of water and surfactant, the mixed soln. of water and surfactant is returned to the degreasing and cleaning stage, the mixed soln. of ethanol and water is passed through a separation membrane capable of selectively separating water and the ethanol freed of water is returned to the deposited surfactant and water removing stage. The ethanol is regenerated in this way.
