Propylenoxid (PO) är en viktig industriell kemikalie som är nödvändig för tillverkning av flera kommersiella produkter och konsumentprodukter. Produktionen av PO är möjlig på flera sätt, alla med sina egna inneboende risker. Metrohm har publicerat en vitbok med fokus på förbättring av olika PO-produktionsmetoder genom automatiserade online- och inline-mätningar av kritiska parametrar direkt vid processen.
Polyuretanplast, propylenglykol och många andra varor härstammar från den kemiska mellanprodukten propylenoxid. Produktionsprocesser beror generellt på marknadsvärdet för biprodukter som styren (från SM-PO-processen), men mer miljövänliga sätt har snabbt vunnit mark under det senaste decenniet.
The hydrogen peroxide to propylene oxide (HP-PO) process is one such method which only co-produces water with PO, but the risks involved are just as great as the other industrial processes. Both the precursors as well as the final products require significant care and attention to handle, purify, and transport.
A safe and secure facility is one of the top requirements for PO manufacturers, and indeed at any industrial chemical plant. Automating chemical measurements performed directly at the sampling point is a superior choice over manual laboratory analyses. Not only is data transferred to the control room in real time allowing for optimization of each part of the process, there is no need to put employees in harm’s way, creating a safer working environment for all. In this white paper, several online application examples for monitoring critical quality parameters in the PO manufacturing process are provided, which are already utilized by top producers.
