In accordance with the requirements of the Investor “Production on heat Balkan Energy DOOEL”, Skopje a detailed analysis of the current situation was carried out. This analysis has identified which equipment is suitable and can be retained, is not suitable and new equipment is required and which equipment is missing and needs to be predicted from the aspect of the required level of automation of the process water treatment system.
On the basis of this analysis, lists of pumps, electrically-operated valves and sensors / measuring equipment have been established, defining existing suitable equipment, existing inadequate equipment (and new changing equipment) and missing equipment that must be installed.
The existing locking and regulating bodies within the system were exclusively manual – manually operated. In order to enable automatic operation of the plant, the project envisages the installation of new shut-off and regulating bodies with electric motor actuators where necessary. The construction of new switchgear cabinets for electric drive and control and control systems with PLC is envisaged. The design solution respected all possible scenarios in the operation of the System for the preparation of process water, taking into account the functioning of the system in normal and emergency mode of operation. The process water treatment system consists of the following subsystems: water supply subsystem, chemical water treatment subsystem, vacuum degassing subsystem, water conditioning subsystem, water storage subsystem and geothermal pump subsystem. The project deals with the automation of all these systems.
