Method and plant for supplying a variable flow rate of a gas from air |
摘要 |
Up to a certain value (D1) of the demanded flow rate (D), this flow rate is brought to the working pressure and is sent to the consumer pipe. When the demanded flow rate is less than the value (D1), the complement to (D1) is brought to a high pressure, greater than the working pressure, and is sent into a buffer tank. Above the value (D1), the flow rate is supplemented by a flow rate which is drawn from the buffer tank and expanded to the working pressure. The method is useful in supplying oxygen to steel works with electric arc furnaces or to copper refineries.
