<p>To increase refrigerating capacity of the main1 throttle separation cycle an external refrigerating circuit for high pressure gas hased on a two-stage freon refrigerating machine K-127 was used.</p>
<p>An increase in working pressure of the cycle I from 120-140 bar to 180190 bar with the substitution of the recuperative heat exchanger I for the heat exchanger developed by ООО I Intellect was also a contributing factor in essential increase in refrigerating capacity о the installation.</p>mini plantliquefied natural gaslarge-capacity plantsмини-заводсжиженный природный газкрупнотоннажные заводы
