Abstract

Selitetään menetelmä ilmakaasulaitoksen kaasun puristuslämmön talteenottoa varten käytettäväksi kaukolämmitykseen. Menetelmä sisältää kaasun puristamisen vähintään kahdessa vaiheessa, kaasun jäähdyttämisen jäähdytysaineen avulla kunkin vaiheen jälkeen ja jäähdytysaineen lämmön talteenoton kaukolämpöjärjestelmässä. Menetelmä on tunnettu siitä, että kaasu jäähdytetään lämpötilaan 50 - 80 °C ja jäähdytysaine lämmitetään lämpötilaan 70 - 110 °C. Sillä tavoin saavutetaan parempi kokonaishyötysuhde. Selitetään myös järjestelmä tämän menetelmän läpiviemiseksi. (kuvio 3)A method for recovering the heat of compression of gas from an air gas plant for use in district heating is described. The method includes compressing the gas in at least two stages, cooling the gas with a coolant after each stage, and recovering the heat of the coolant in a district heating system. The method is characterized in that the gas is cooled to a temperature of 50 - 80 °C and the coolant is heated to a temperature of 70 - 110 °C. In this way, a better overall efficiency is achieved. A system for carrying out this method is also described. (Figure 3)
