Helping ensure soda quality
September 1st 2007

Brunner Mond BV, a producer of soda ash, has selected Krohne's BM70 A high temperature level radars to measure the precise availability of coke and limestone chunks used in the production of soda.

Soda manufacture is an exact process and the level radars perform an essential role in making sure the required amounts of coke and limestone are available to be mixed together.

The application is made particularly difficult due to the continuous presence of smoke, dust and high temperature in the 40m high vessels that contain the materials.

The BM 70 A level radar is noncontact and uses electromagnetic waves to detect the surface of materials. It is capable of measuring to a depth of 100m.

Operation of the instrument makes it possible to 'cut through' the dust and smoke to the depth required to deliver accurate, reliable level measurement.

The high temperature version of the BM 70 A is fitted with a distance piece, designed to protect the electronics from heat. This enables the instrument to operate reliably at high temperatures.

The BM 70 A meters have also been installed in the plaster lime bunkers, where the incinerated lime (stone) is stored, as well as in the ground lime (stone) bunkers.
