Measuring the Electric Conductivity by use of Clean-in-Place (CIP) System

Introduction

In the manufacturing process of Pharmaceutical, Chemical and Food & Beverage industries, the cleaning and sterilization of tanks and piping are done with various cleaning solutions, fresh or hot water and steam after manufacturing products. Clean- In-Place (CIP) is the system designed for automatic cleaning and disinfecting. The recovery of cleaning solutions contributes significantly to reduce chemical costs and wastewater processing costs.

Yokogawa FLXA202/FLXA21 inductive conductivity transmitter has earned a reputation in the recovery of cleaning solutions because it can take measurements with good boundary surface precision over a wide range.

  • Reduces operating costs

Process Overview

Inductive Conductivity SensorCIP systems depend on the process differentiations of Pharmaceutical, Chemical and Food & Beverage. In addition, the cleaning solutions and chemicals are different. The chemicals that are generally used are hypochlorous acid, caustic soda, and nitrous acid. In a cleaning solution recovery system, the process lines and piping are cleaned with an initial cleaning solution. After that, the cleaning solution is cleaned with fresh water. The cleaning solution is recovered at that point, but since it gradually becomes diluted with fresh water, recovery is discontinued and the solution is discharged through a drainage line when the concentration of the cleaning solution drops below the standard value. The cleaning with different solutions or fresh water, the recovery of the cleaning solution, and the discharge of waste solution are repeatedly carried out. In addition, sterilization with steam or cleaning with distilled water or de-ionized water is performed as a final step in some cases.

Industrieën

  • Chemie

    Chemische fabrieken zijn afhankelijk van continu- en batch-productieprocessen die elk verschillende eisen stellen aan een besturingssysteem. Een continu proces vereist een robuust en stabiel besturingssysteem dat niet faalt en de productielijn doet stilvallen. Bij een batchproces ligt de nadruk ligt op een besturingssysteem dat een grote flexibiliteit biedt bij het aanpassen van o.a. formules en procedures. Beide soorten systemen moeten worden beheerd naar aanleiding van de productiegeschiedenis rond de kwaliteit van het product, en in staat zijn om niet-routinematige werkzaamheden uit te voeren. Met een uitgebreide productportfolio, ervaren systeemingenieurs en wereldwijde verkoop- en servicenetwerk heeft Yokogawa een oplossing voor elk fabrieksproces.
