The plant was built in a new building next to the existing production plant and comprises several floors. The interfaces to the existing plant components were an important point, as tank storage and process water are used by both plants. After successful commissioning, the process was continuously optimized and further developed by the customer.
Project DescriptionThe system comprises several process steps:
Firstly, the acid and water are mixed. It is important that the mixing ratio is correct. Otherwise, undesirable effects such as too much or too little heat can occur. A heat exchanger can be used to cool or heat the mixture during filling - depending on the product.
Magnetite is then added using a crane. A scanner is used to measure the fill level of the trough so that the crane knows where it is worth accessing.
The mixture now has to dissolve for a few hours. To prevent it from boiling over, a little water is added from time to time.
The solution is then filtered using a chamber filter press and filled into the reactor. There, oxygen is added under pressure until the desired oxygen balance is achieved.
The finished product is pumped into the intermediate tank and must still be cooled before it can be transferred to the tank farm.
Currently 3 different products can be produced: Trifer12s, Trifer12.5 and Trifer200, which are mainly used in sewage treatment plants, e.g. as flocculants.
The interfaces to the existing plant components were an important point, as tank storage and process water are now used by both plants.
The process is continuously optimised and further developed by the customer. Flexible and well-structured software is a must here. The uncomplicated and good co-operation between the customer and Deleproject is an important component for success.
The automation engineering was realised with Deleproject's own framework for PLC (Siemens TIA) and HMI (zenon).
