炼油厂的重质油品(如燃料油、农用柴油的组分油等)一般均在工艺装置内经换热后再用水箱冷却至一定温度,才送至油品储运系统的罐内储存。在水箱冷却器中被冷却水取走的热量,一般称为装置的剩余热量。目前,这部份热量实际上是浪费掉了,还消耗了大量冷却水。 Oil refinery heavy oil (such as fuel oil, agricultural diesel oil, etc.) are generally in the process unit by the heat exchanger and then cooled to a certain temperature tank before being sent to the oil storage and transportation system tank storage. The amount of heat removed by the cooling water in the radiator of the tank is generally referred to as the residual heat of the unit. At present, this part of the heat is actually wasted, but also consume a lot of cooling water.
