Located in Faisalabad, Pakistan, National Aerochem is a chemical plant that produces formaldehyde (CH2O). The plant’s production capacity is 140 tons per day. By the cracking of methanol, formalin is produced – it is 37 weight percent of formaldehyde in water. Formaldehyde and urea are used to make urea-formaldehyde resins, which are used as adhesives and binders for chipboard and plywood.
In 2015, Alpha Engineering installed a SCADA-based control system at the plant.
The system consists of a control cabinet, which houses a Siemens S7-1200 PLC, and the Reliance SCADA/HMI system, which provides an overview of the production process. The Siemens PLC collects and controls the process parameters and communicates with Reliance over Ethernet.
The Reliance 4 system is used as front-end SCADA software. Bringing some new features, it is
a replacement for the existing DCS system.
The Reliance SCADA system provides monitoring and control of the following:
The main visualization window
This screen displays all the important parameters, different temperatures and pressures, flow meters, and PID control valves including a temperature trend at the bottom (from this window, all the pumps, burners, and valves can be monitored and controlled).
Try the Reliance SCADA/HMI system on several example projects or download the installer of the trial version for free.
