Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- analyzers that have been developed for water (drinking water, waste water, boiler feed water,...).
This paper presents a solution that is based on an online FID (flame ionization detector) to monitor TOC- contamination directly in the hot steam/hot condensate in real time to allow quick and reliable treatment (i.e. removal) of the polluted condensate.
