Abstract
A liquefied gas producing facility is provided and includes: a first heat exchanger, a first refrigerant compressor, a second heat exchanger, a second refrigerant compressor, air-cooling heat exchangers for a first refrigerant, air-cooling condensers for a first refrigerant, air-cooling heat exchangers for a second refrigerant, air-cooling condensers for a second refrigerant and a mist spraying device. The liquefied gas producing facility can produce liquefied gas by liquefying feed gas which contains methane as a main component.
Claims10
A liquefied gas producing facility which produces liquefied gas by liquefying feed gas which contains methane as a main component, the liquefied gas producing facility comprising:
- a first heat exchanger that causes a first refrigerant to exchange heat with the feed gas and a second refrigerant to cool the feed gas and the second refrigerant;
- a first refrigerant compressor that compresses the first refrigerant that is gasified through cooling the feed gas and the second refrigerant in the first heat exchanger;
- a second heat exchanger that causes the second refrigerant to exchange heat with the feed gas that is cooled by the first heat exchanger to further cool and liquefy the feed gas;
- a second refrigerant compressor that compresses the second refrigerant that is gasified through cooling the feed gas in the second heat exchanger;
- air-cooling heat exchangers for the first refrigerant that air-cool the first refrigerant that is discharged from the first refrigerant compressor;
- air-cooling condensers for the first refrigerant that air-cool the first refrigerant that is cooled by the air-cooling heat exchangers for the first refrigerant to liquefy the first refrigerant;
- air-cooling heat exchangers for the second refrigerant that air-cool the second refrigerant that is discharged from the second refrigerant compressor;
- air-cooling condensers for the second refrigerant that air-cool the second refrigerant that is cooled by the air-cooling heat exchangers for the second refrigerant to liquefy the second refrigerant;
- and
- a mist spraying device that sprays a mist containing demineralized water toward cooling air supplied to at least one of the air-cooling condensers for the first refrigerant.
A method for producing liquefied gas by liquefying feed gas which contains methane as a main component, the method comprising the steps of:
- causing, by using a first heat exchanger, a first refrigerant to exchange heat with the feed gas and a second refrigerant to cool the feed gas and the second refrigerant;
- compressing, by using a first refrigerant compressor, the first refrigerant that is gasified through cooling the feed gas and the second refrigerant in the first heat exchanger;
- causing, by using a second heat exchanger, the second refrigerant to exchange heat with the feed gas that is cooled by the first heat exchanger to further cool and liquefy the feed gas;
- compressing, by using a second refrigerant compressor, the second refrigerant that is gasified through cooling the feed gas in the second heat exchanger;
- air-cooling, by using air-cooling heat exchangers for the first refrigerant, the first refrigerant that is discharged from the first refrigerant compressor;
- air-cooling, by using air-cooling condensers for the first refrigerant, the first refrigerant that is cooled by the air-cooling heat exchangers for the first refrigerant to liquefy the first refrigerant;
- air-cooling, by using air-cooling heat exchangers for the second refrigerant, the second refrigerant that is discharged from the second refrigerant compressor;
- air-cooling, by using air-cooling condensers for the second refrigerant, the second refrigerant that is cooled by the air-cooling heat exchangers for the second refrigerant to liquefy the second refrigerant;
- and
- spraying a mist containing demineralized water toward cooling air supplied to at least one of the air-cooling condensers for the first refrigerant.
