Applications in solvent recovery plants

SCORPIO 3000 – Steam Stripping
VOC analyzer ideally suited for solvent recovery plants using steam stripping technology, widely applied in high energy‑efficiency industrial processes.

TAURUS 4000 – Inert Gas Stripping
Dedicated solution for solvent recovery plants with inert gas stripping, particularly common in the European chemical industry.

Advantages of Nira Srl VOC analyzers
Unique monitoring of the stripping phase
The only system capable of measuring solvent concentration during the stripping phase of adsorbers, significantly improving process control.
Outstanding long‑term measurement stability
The sequential sampling cycle replaces continuous capillary flow, reducing measurement drift and minimizing corrective interventions.
Reduced operating and maintenance costs

Exclusive sampling valve with no moving mechanical parts
Ejector‑based sampling system, maintenance‑free, eliminating the need for a traditional sampling pump
Only one technical gas required: hydrogen

Easy integration into industrial plants
Embedded PC technology with Windows® operating system, equipped with Ethernet and USB interfaces, ideal for integration into industrial automation systems.

Configurable VOC and TOC analysis points

Monitoring of solvent concentration at the inlet of the solvent recovery plant
Control of VOC concentration inside activated carbon adsorbers
TOC monitoring at stack emissions, in compliance with European environmental regulations
Additional analysis points configurable according to specific customer requirements


Robust configuration for industrial environments
The system is supplied in an independent IP55 rack, complete with a multiline VOC sampling system, specifically designed for installation in harsh industrial environments.
