摘要： PURPOSE:To reduce power cost, in a pressure swing method, by interposing a dehumidifying part and a heat exchange part in a flow passage, which supplies a gaseous mixture to an adsorbing tower, from the upstream side and performing dehumidification and cooling in an adsorbing process while reversely flowing adsorbed gas in a regeneration process. CONSTITUTION:Air compressed by a compressor 32 is passed through a dehumidifying tower 37 and subsequently cooled by a plate fin heat exchanger 41 and further cooled by a cooling tower 43 and again cooled by a heat exchanger 47 to enter a N2-adsorbing tower 50 to adsorb N2 while a product O2 is collected. The N2-adsorbing tower 50' in a regeneration process is reduced in pressure by a vacuum pump 55 and desorbed N2 reaches a cooling tower 43' through a heat exchanger 47' to recover cold heat and reversely flows through a dehumidifying tower 37' while dry N2 is flowed to regenerate the humidifying tower 37' and moisture is discharged out of the system along with N2 from the vacuum pump 55.

摘要： PURPOSE:To make it possible to prevent the backflow of char to the second- stage gasifying furnace and provide smooth and continuous operation, by introducing char separated from a gas produced in the second-stage gasifying furnace into the first-stage gasifying furnace by a transfer means with a gas. CONSTITUTION:A solid fuel, e.g. coal, is fed to a fluidized bed 7 of the second- stage gasifying furnace 6, and reacted with a gasifying agent 18 containing air, oxygen and/or steam and produced gas in the first-stage gasifying furnace 1 fed from an intermediate cyclone 5 at 700-1,200 deg.C and converted into a produced gas and char. The residual particles of the fluidized bed 7 in the second-stage gasifying furnace 6 and fine particles (char) are passed through an overflow pipe 12 and then introduced into a transfer chamber 24 of a fluidizing transfer means 23. The char is then introduced into the first-stage gasifying furnace 1.

2 at low temps. and pressure, and connecting the outflow passages of both adsorption towers at the end of adsorption and regeneration in a pressure swing method.

2 , and N
2 is adsorbed and removed to recover product O
2 from a tank 13. Na faujasite is used as the adsorbent, and the adsorption tower is sent under low- temp. condition. Meanwhile, the pressure of an adsortion tower 8' is reduced by a vacuum pump 16 through a flow passage 15, and regeneration is carried out. The adsorption tower 8 at the end of adsorption and the adsorption tower 8' at the end of regeneration are connected for at least 6sec by opening valves 10 and 10' send O
2 remaining in the adsorption tower 8 to the adsorption tower 8'. Consequently, the recovery rate of product O
2 is enhanced.

摘要： PURPOSE:To produce O2 with inexpensive adsorbents by packing the upper stream side of an adsorption tower with Ca-Na-A type zeolite and the downstream side with Na-X type zeolite treated with an aqueous NaCl soln. so as to reduce the consumption unit of power required and the amount of the adsorbents required. CONSTITUTION:A gaseous mixture contg. O2 and N2 as principal components is introduced into an N2 adsorption tower at a temp. below room temp. under atmospheric pressure -3atm. N2 is selectively adsorbed in the tower, high purity O2 or O2 enriched gas is discharged, and the tower contg. the adsorbed N2 is evacuated to 0.04-0.55atm. to carry out regeneration. In this method, the upper stream side of the tower where the concn. of O2 does not exceed 50% is packed with Ca-Na-A type zeolite, and the downstream side is packed with Na-X type zeolite treated with an aqueous NaCl soln. by dipping. The Ca-Na-A type zeolite adsorbs a larger amount of N2 than the Na-X type zeolite by about 20% in the region where the concn. of O2 does not exceeds 50% while maintaining N2 selectivity comparable to that of the Na-X type zeolite, so O2 is produced with the N2 adsorbents adsorbing a large amount of N2 and maintaining high N2 selectivity as a whole in the N2 adsorption tower.

摘要： PURPOSE:To prevent the corrosion in the system as well as to reduce the power consumption in cooling the condensate during a suspension period of operation of a steam power generating plant etc. by an arrangement in which a water circulating pump is stopped, and a separate water circulating pump for suspension and a sea water heat exchanger for suspension period are operated instead. CONSTITUTION:During the suspension period of operation, a water circulating pump 16 is stopped, and a separate circulating pump for suspension 19 is started to cause the cooling water to flow from a circulating water pipe for suspension 18 to a sea water heat exchanger for suspension period 20 to cool down the condensate that is heated by an ejector steam condenser 9 and a gland steam condenser 11 and flows into a condensate minimum flow line 12 for cooling. By this arrangement, the amount of the cooling water can be reduced, and the cooling can be achieved by a less power.

摘要： PURPOSE: To separate efficiently N
2 and O
2 from a gaseous mixture under the condition of low temp. and low pressure by using at least two adsorbing towers packed with a mineralozical name, sodium faujasite represented by Na-X.
CONSTITUTION: Air compressed to 1.05W3 ata by a compressor 2 is introduced to an adsorbing tower 8 via a passage 6. N
2 in the compressed air is removed by a N
2 adsorbent 9 and the oxygen concentration is increased as the air is sent to the latter part of the tower. Later the compressed air is recovered as a product O
2 via a product O
2 tank 13. Since said tower 8' is evacuated by a vacuum pump 18 connected thereto, and N
2 adsorbed by the adsorbent 9' in the adsorbing tower 8' is desorbed easily by a part of the product O
2 , the adsorbent is regenerated for a short time. When the adsorbent 9 in said tower 8 is saturated, and regeneration is ended by desorption of N
2 from N
2 adsorbent in said tower 8, the flow passage 6 of entering air is switched to another passage 6'. By repeating alternately above-mentioned method, the product O
2 can be recovered continuously.
