The present invention relates to a method for producing pressurized liquefied natural gas and a production system used therefor, and a dehydration step in which a natural gas is supplied from a natural gas field and dehydrated without removing acid gas, and a dehydration step is completed. Pressure liquefaction including liquefaction stage to produce pressurized liquefied natural gas by liquefying natural gas without pulverizing NGL (Natural Gas Liquid) to pressure of 13-25bar and temperature of -120 ~ -95 ℃ A natural gas production method and a production system used therefor are provided. According to the present invention, it is possible to reduce plant manufacturing costs and maintenance costs, to reduce the unit cost of liquefied natural gas production, and it is difficult to secure economic efficiency with existing systems It is possible to guarantee economic benefits and shortened payback period.
