Ceilcote: a versatile lining

Ceilcote linings from KCH Keramchemie (UK) Ltd are being extensively used in the Middle East to protect desalination equipment against corrosion.
Throughout the Middle East region, desalination plants are essential for the provision of clean and potable water for both irrigation and domestic purposes.
Desalination plants process sea water in deaerators and flash evaporator units to produce fresh water. The environment within the sea water intake lines, deaerator vessels and flash evaporator units is extremely corrosive to carbon steel so protection is critical.
An installation completed by Ceilcote's approved applicator, Anticorrosion Protection Systems, in Dubai in the UAE involved lining the interior of all sea water intake lines and deaerator vessels with a glass flake polyester coating and lining the evaporator channel head boxes with ebonite rubber. After five years of continual operation since the installation was commissioned, a recent inspection is reported to have indicated that all installed linings were in good condition and required no remedial work.
Another example of the lining's versatility is the storage of vegetable oils. Traditionally in the UK, vegetable oils such as palm oil, soya bean oil, rapeseed oil, corn oil and sunflower oil are stored in bulk as unrefined products. There is an increasing demand, however, for vegetable oils to be stored as refined products. Whilst unrefined products may be stored in carbon steel vessels, refined oils require storage in either stainless steel, or suitably lined, vessels and tanks.
The majority of storage facilities in the UK store unrefined vegetable oils in extensive tank farms, manufactured primarily from carbon steel. To meet the increasing demand for the storage of refined vegetable oil products within these existing facilities, the fastest and most economical method is to line them with suitable food-grade coating systems.
Ceilcote 242 Flakeline has recently been used for the internal lining of storage tanks that will hold a wide range of vegetable oils at temperatures up to 70°C. Independently tested to meet food-grade requirements, Ceilcote 242 Flakeline is spray applied to the degreased and gritblasted surface of the storage tanks to a finished thickness of approximately 1.5mm.
Following initial storage of palm oil in a tank 8.25 metres in diameter and 16 metres high, the installed Ceilcote 242 Flakeline lining was said to be found to be in excellent condition upon inspection and ready for a new cargo.
