Reducing the high pressure of small air separation equipment with medium pressure expansion machine can reduce the energy consumption of air separation equipment. Here is a simple analysis of the influence of the temperature before the expansion machine on the high pressure. Under the condition that the total cooling loss and the gas temperature before expansion are fixed, from the perspective of the heat balance of the total unit, increasing the high pressure can reduce the expansion gas; but from the perspective of ensuring the working condition of the cold section heat exchanger, with the increase of high pressure, it is required to increase the expansion amount and reduce the air flow into the cold section heat exchanger. Therefore, the selection of working pressure and expansion amount of the process should meet both requirements. When the total cooling loss and working pressure of the process remain the same, increasing the temperature of expansion forward gas can increase the...

Air cooling tower is also a hybrid heat exchanger. In order to make the cooling water fully contact and strongly mix with the air to enlarge the heat transfer area and strengthen the heat transfer, the "stuffing Tower" or "sieve plate Tower" are usually used, and hollow spray tower is also used. The stuffing Tower is a round container made of steel, which is filled with stuffing (porcelain ring, or plastic ring, etc ). The cooling water sprays down from the tower top and is mixed with the bottom-up flowing air for heat and mass exchange. Air transmits heat to cooling water to lower the temperature itself and raise the water temperature. In order to prevent the air from dripping out of the water, the upper part of the tower is usually equipped with laxige ring (or stainless steel wire mesh) stuffing separator (also called capture layer) and mechanical water separator (inertial separation ). The cooling water sprayed out by the spraying device flows downward along the stuffing layer t...
