ILS-Integrated Lab Solutions Uses Rheotherm Model 210
in High-Temperature Reactor
ILS-Integrated Lab Solutions, based in Berlin, solved a difficult application challenge in their Vinyl Acetate Monomer Reactor using Intek’s Rheotherm Model 210. The process, which involves extremely high temperatures and low flow rates, could not be controlled using most commercial thermal mass or Coriolis mass flow controllers. The application required the selection and integration of both a flow sensor and a control valve capable of handling both the high temperature and the corrosive acid used in the process. They chose to use a high-temperature Intek flow meter combined with an Equilibar dome-loaded multiple orifice control valve.

Installation of Steam Side Retrofit Results In Lower Condenser Pressure (0.6-1.0″ HgA)
Performance study by Intek on an Ingersoll Rand and a Westinghouse condenser concluded that the condensers were under performing. Intek’s advanced instrumentation subsequently identified air storage in the steam space as the main culprit for the poor performance. A condenser retrofit to both units designed by Intek and installed during a retubing outage eliminated the air storage and significantly improved condenser performance.

Optimizing Condenser Performance: A Case Study
Intek undertook a project to improve the performance of a 37 year old condenser during a retubing outage. Since coming back on line after the retrofit, the plant has achieved record low condenser pressures for equivalent operating conditions, record low condenser condensate DO levels below 4 ppb, a 200% increase in polisher resin life, and a 6% heat rate reduction for the two years following the retrofit outage.
