Client want to cool the 20 MMSCFD gas (Methane 100%) from 42 deg C to 33 deg C. Water is available at 28 deg C. My question is approach temp 5 deg is not too ambitious? Then what would be cheapest way to manufacture the heat exchnager. Normal shell & tube heat exchnager would require extra cooling tower to cool the water and pumps to pump the water (Plant does not need cooling water for other process). Iis there any way to integrate this three equipment to something like wet surface cooler or others?
