Development of piping design for large air separation units

The pipe connecting the plate-fin heat exchanger to the liquid-air subcooled gas is the largest diameter pipe in a set of large air separation units. By adjusting the position between the liquid-air liquid-nitrogen subcooled gas and the main tower, the stress value can be effectively reduced.

Liquid nitrogen separation system in liquid air separation plants

After pressurisation, it returns to the heat exchanger to recover the cold volume of liquid air separation plants and liquefy it into liquid nitrogen, part of which is warmed up to about 123°C by the heat exchanger through the eighth pipeline after a history of throttling, and is pumped out to the medium pressure circulation nitrogen press. Another part of the liquid nitrogen enters the first gas-liquid separator via the fifth pipe. Part of the separated liquid nitrogen goes through the seco...

Small air separation units water circulation system problem prevention

Sediment deposition Determine whether the system has sediment deposition: circulating water turbidity for a long time (3 months) high (greater than 20NTU), heat exchanger tend to temperature rise significantly (longer than 1 ℃ / month) Treatment method: chemical cleaning, with hydrochloric acid with hydrofluoric acid (sediment temperature increases will have thermal scale precipitation). Biological slime determine whether there is biological slime deposition: cool water tower has a lar...
