Applied to reuse steam condensate water in Medium petrochemical plant to boiler feed water

In Thailand's petrochemical industrial estate which has a small or medium-size plant, boiler feed water is bought from the external boiler feed water provider to use in an incinerator to make steam for plant use, and the steam condensate water that comes after the incinerator process is sold back to the provider as well. The cost gap between bought water and sold water is considered a waste since the income gained from selling post-boiled water is less than expenses from bought water. In this paper, the research to improve the steam condensate water quality and reuse the water has been proposed. This application is to be considered to build the steam condensate treatment unit for treating water potential to reduce the overall operation cost (OPEX). The online analyzer is being used to control the chemical dosing package via a plant control system to check the quality of water and treat it in real-time so the water can be reused.
