摘要： PURPOSE:To inspect the pressure proof of high pressure piping simultaneously with the assembling and adjusting operation of high pressure turbine casing by sealing an annular space which includes a weld line and contacts the high pressure casing and the pipe to be inspected by packing. CONSTITUTION:A high pressure lower half casing 1 is set and then a main steam pipe 4 and further a steam control valve are set; while respective pipes 4 are welded temporarily simultaneously with the assembly of a high pressure upper half casing 2, a specific heat treatment is carried out to weld respective parts. Then, annular packings 18 and 18' which are sectioned in a C shape are brought into the casing 1 and pipe 4 to seal the annular space W contacting the weld line W, and further packing pressers 19 and 19' are used to back up the packings 18 and 18'. In this state, pressure liquid is injected into the space sealed by the annular packings and pressurized to detect whether or not there is the defect of the weld zone W.

摘要： PURPOSE: To obtain a high colorific value coal with low water content even after transportation and/or storage, by distilling off tar from coal while dehydrating the coal, followed by coating the vapor of said tar on the surface of the coal.
CONSTITUTION: Tar is distilled out of coal while carrying out a heat treatment for the coal, most preferably at 350W450°C. Said tar is evaporated into its vapor, which is then subjected to coating on the surface of the heat-treated coal under such a condition that the temperature difference between the vapor and the heat-treated coal may normally be 150W300°C, thus obtaining the objective modified coal. The amount of the tar distilled out of the coal is, in general, 4W 12wt% on the dry basis.

摘要： PURPOSE:To increase the concentration and the yield of O2 gas product by controlling the flow rate of air introduced into an adsorption tower, in a continuous oxygen- concentrating method wherein adsorption of N2 by introducing air into a plurality of adsorption towers, desorption of N2 by reducing a pressure, and equalization of pressure are sequentially repeated. CONSTITUTION:When conducting N2 adsorption and N2 desorption respectively in adsorption towers 1 and 2, solenoid valves 8, 10, 15 are opened and solenoid valves 9, 11, 16-18 are closed. In this condition, air is fed into a throttle plate 6 through a compressor 4 to adjust its flow rate, then it is fed into the tower 1, where N2 is adsorbed and O2 is fed into a pressure-equalizing tank 13. Thereafter, O2 is taken out through a pipe 14. On the other hand, N2 adsorbed in the tower 2 in a previous step is discharged through the solenoid valve 15 and a pipe 19 while returning the pressure of N2 to the atmospheric pressure. After the desorption of N2 in the tower 2 is completed, the valve 17 is opened and valves 9, 11, 15 are closed, then O2 in a compressed state in the tank 13 is introduced into the tower 2 and the pressure is equalized. Thereafter, adsorption and desorption of N2 are conducted respectively in the towers 2 and 1, in which case the throttle plate 6 prevents a large amount of air from flowing instantaneously into the adsorption tower at the time of adsorption, and the purposes can be attained.

摘要： PURPOSE:To obtain a polyester economically, by a method wherein in carrying out a solid-phase polycondensation of a polyethylene terephthalate polymer, an inert gas to be passed through the polymn. mixt. is recycled for use, and at the same time the inert gas is used as a purge gas for desorption and regeneration in an adsorption tower. CONSTITUTION:A particulate polyethylene terephathalate polymer is continuously supplied from a hopper 2 to a solid-phase polycondensation reactor 1, and subjected to a solid-phase polycondensation reaction, and an inert gas is supplied to the lower part of the reactor 1 to remove impurities such as acetaldehyde. The inert gas is purified in an adsorption tower 7 for purification, and recycled for use. Just before the adsorbent of the adsorption tower 7 is saturated with impurities, gas flow is switched. A fresh inert gas is supplied through a conduit 11. The inert gas which bas passed through the reactor 1, is used as a purge gas for desorption and regeneration in the adsorption tower 7, whereby the amount of the inert gas to be used is reduced to the min. amount and the polyester can be obtd. economically.

摘要： PURPOSE:To enhance the O2 concn. and a yield ratio to a large extent by a method wherein, in concentrating O2 in air, the first adsorbing agent for adsorbing N2 and the second adsorbing agent for adsorbing O2 are packed in an adsorbing agent packing tower in a predetermined amount and the adsorbed O2 of the second adsorbing agent is utilized whtn the N2 adsorbing agent is regenerated under vacuum. CONSTITUTION:The second adsorbing agent 2 for selectively adsorbing O2 such as a synthetic zeolite 4A type is packed in a zone 2 within a pressure packing tower 1 and the first adsorbing agent for selectively adsorbing N2 such as a synthetic molybdenite is packed in a zone 3 and a check valve 5, a stock material air inlet pipe 4 having a solenoid valve 6, a concentrated O2 outlet pipe 7 having a sloenoid valve 9 and a timer 13 are arranged to constitute an apparatus as well as the amount of the second adsorbing agent is regulated so as to adsorb O2 smaller than the O2 amount after the air is passed through the first adsorbing agent. When the first adsorbing agent is subjected to the vacuum regeneration, the valve is switched by the timer 13 to exhaust the pressurized air from a pipe 12. The O2 adsobred in the second adsorbing agent is passed through the zone 3 and utilized in the regeneration. Thereby, the O2 concn. in air and the O2 yield ratio can be enhanced to a large extent.
