The direct chlorination catalyst is known to contaminate the effluent EDC with FeCl3 — a highly corrosive compound which fouls machinery. Reasons for controlling FeCl3 and Cl2 levels using analysis at this point include:
ANALYTICAL SOLUTION: OMA-300 PROCESS ANALYZER
The OMA-300 simultaneously monitors FeCl3 and Cl2 in the direct chlorination effluent stream. Using a high resolution dispersive UV-Vis spectrophotometer, this system provides unrivaled dynamic range in measuring chlorine compounds from trace to high concentration. Since the device uses an ultra-safe fiber optic cable design, the corrosive sample fluid is confined to a specialized flow cell and never enters the analyzer electronics enclosure.
Moisture is known to form a highly corrosive mixture with HCl and Cl2. Above 100 ppm, H2O will aggravate the corrosive effects of the produced EDC and VCM streams. The moisture also carries other undesirable impurities which reduce the quality of these products. Since removal of moisture is more economically viable than removing other components of the corrosive mixture, this is the main target of corrosion control.
VCM process operators typically measure 0-200 ppm moisture at these analysis points for process control.
ANALYTICAL SOLUTION: MICROSPEC MCP-200 MODULAR IR ANALYZER
The MCP-200 is a rugged NDIR concentration monitor designed for simple reliability in continuous moisture measurement. This solid state device has a zero offset feature which removes the need to obtain totally dry (zero H2O) zeroing fluid, thus making the Auto Zero functionality practical and inexpensive without sacrificing accuracy. This system provides the fast response 0-200 ppm moisture reading required for tight VCM process control.
This measurement set provides a range of benefits to the process operator:
SOLUTION: MICROSPEC SERIES MODULAR ANALYZERS
The MicroSpec series of rugged, ultra-modular concentration monitors offers a dedicated solution for each of these measurements. An integrated interface reads the concentration outputs from all of the connected MicroSpec units. This design leverages the modular design of the MicroSpec series by performing Auto Zero on all detectors synchronously (maximizing system uptime) and minimizing the system’s physical footprint.
