For an Air Separation Unit (ASU), APC can be used to improve the performance of the cryogenic distillation process by continuously monitoring key process parameters such as temperature, pressure, and flow rates, and adjusting them in real-time to maintain optimal operating conditions. By using APC, operators can improve product quality, reduce energy consumption, and minimize the risk of equipment failure.
APC can be used to optimize the operation of the distillation column by adjusting the column parameters such as reflux ratio, tray temperatures, and feed rates to maximize the separation efficiency and minimize energy consumption.
Control of the air compressor can be used APC to control the air compressor to maintain a steady flow rate and pressure, which is critical for the operation of the ASU.
For monitoring of product purity, APC can be used to continuously monitor the purity of the nitrogen, oxygen, and argon products, and adjust the process parameters to maintain the required product specifications.
i-APC can offer the service to not only improving both production and quality but also handling the operating transition when the downstream demand of the Nitrogen Gas (GAN) or Oxygen GAS (GOX) is changed due to customer requirements. Overall, the use of APC in ASUs can lead to significant improvements in process efficiency, product quality, and safety, making it an essential tool for modern industrial operations.
