| 20120125761 | HEAT INTEGRATED DISTILLATION APPARATUS - Provided is a heat integrated distillation apparatus in which energy efficiency and a degree of freedom in design is higher than a normal distillation column, and in which maintenance of the apparatus is simple. The heat integrated distillation apparatus includes: rectifying column ( | 05-24-2012 |
| 20120098252 | PIPING SYSTEM - A piping system comprising: a main pipe; a first pipe member connecting an equipment nozzle and the main pipe via a first bellows; a second pipe member connected to a side part of the main pipe; a third pipe member connected to the other end of the second pipe member via a second bellows; first and second tie rod support members fixed to the first and third pipe members; tie rods that interconnect the tie rod support members; and an anchor that sets a portion of the main pipe as a fixed point. Lengths of the pipe members between the tie rod support members are determined so that the first bellows contracts by thermal expansion of the equipment nozzle, the first pipe member, and the pipe member of the main pipe below the anchor, and the second bellows contracts by an amount equally to that of the first bellows. | 04-26-2012 |
| 20120060931 | METHOD FOR ANALYZING AQUEOUS AMMONIUM CARBAMATE SOLUTION, AND METHOD FOR OPERATING UNREACTED GAS ABSORBER - There are provided a method for analyzing an aqueous ammonium carbamate solution whereby the composition of an unreacted-gas absorber outlet liquid can be specified in real time, and a method for operating an unreacted gas absorber by use of the same. The method for analyzing the composition of an aqueous ammonium carbamate solution includes determining ammonia component concentration, carbon dioxide component concentration, and water concentration of the aqueous ammonium carbamate solution, which is the unreacted-gas absorber outlet liquid in a urea production process, by using a correlation among viscosity, temperature, and carbon dioxide component concentration of the aqueous solution and a correlation among density, temperature, ammonia component concentration, and carbon dioxide component concentration of the aqueous solution, wherein the ammonia component concentration is a concentration of a sum of free ammonia and equivalent ammonia of ammonium carbamate which are contained in the aqueous solution, and the carbon dioxide component concentration is a concentration of equivalent carbon dioxide of ammonium carbamate contained in the aqueous solution. | 03-15-2012 |
| 20110250102 | REACTOR - There is provided a radial flow reactor having a multi-pass structure in which loading and unloading of granular packing are easy and which does not impair the reaction performance. The reactor includes, in an upright tubular reactor vessel: a packing region for housing a continuous packed bed of granular packing; and an outer and an inner passages disposed outside and inside the packing region, respectively, allowing a fluid to flow in the axial direction. The reactor is configured so that the fluid can pass between the packing region and the outer passage and between the packing region and the inner passage. The reactor further includes at least one of an outer partition structure and an inner partition structure. The outer partition structure includes: an outer partition plate partitioning the packing region in the axial direction with a gap allowing the granular packing to pass therethrough between the inner border of the packing region and the outer partition plate; and a blocking section for preventing the fluid from flowing through the outer passage in the axial direction. The inner partition structure includes: an inner partition plate partitioning the packing region in the axial direction with a gap allowing the granular packing to pass therethrough between the outer border of the packing region and the inner partition plate; and a blocking section for preventing the fluid from flowing through the inner passage in the axial direction. | 10-13-2011 |
| 20110178254 | APPARATUS FOR MANUFACTURING POLYMER RESIN, POLYMERIZATION VESSEL, AND METHOD FOR MANUFACTURING POLYMER RESIN - An apparatus for manufacturing a polymer resin comprises a polymerization vessel, a bearing part, a protection part, a circulating cooling means, a raw material-injecting nozzle and a flow path-constituting part. The protection part forms a first flow path between the protection part and the side face of the agitation axis. The circulating cooling means includes a circulating inlet nozzle provided on a side face of the protruding part so as to be opposite to the protection part. The flow path-constituting part is provided between the bearing part and the protection part so as to cover the side face of the agitation axis, to fix the bearing part and the protection part. This flow path-constituting part forms a second flow path between the side face of the agitation axis and the flow path-constituting part and a third flow path for coupling the second flow path with the raw material-injecting nozzle. The first to third flow paths constitute a continuous flow path and an uppermost end of the first flow path is opened to the inside of the protruding part. The gap, part of the first flow path other than the uppermost end, the second flow path and the third flow path are isolated from the inside of the protruding part. | 07-21-2011 |
| 20100224535 | Carbon supported catalyst for demetallation of heavy crude oil and residue - A supported carbon having high surface area, high pore volume containing (i) molybdenum (ii) a metal of non noble Group VIII, (iii) phosphorous, is used for hydrometallization of heavy crude oil and residue. The catalyst contains about 6 to 15 wt % molybdenum as MoO | 09-09-2010 |
| 20100145985 | DOCUMENT MANAGEMENT APPARATUS, METHOD, AND PROGRAM - A document management device ( | 06-10-2010 |
| 20080219902 | REACTOR - A reactor including a reactor vessel and heat exchange tubes provided in the reactor vessel. The reactor vessel includes a tubesheet and is configured to receive a reaction fluid. The tubesheet has a first plate member configured to contact the reaction fluid and a second plate member configured to not contact the reaction fluid. Heat exchange tubes are provided in the reactor vessel and fixed to the first plate member. The heat exchange tubes are configured to receive a heat exchange medium. At least a portion of the first plate member configured to contact the reaction fluid is made of a metal that has a high corrosion-resistance against the reaction liquid, and the second plate member is made of a metal that has a low corrosion-resistance against the reaction liquid. The second plate member is detachably fixed to a remainder of the reactor vessel. | 09-11-2008 |
