Level measurement in the diazotization vessel

Application

In the diazotization process, the individual raw materials for colour pigment production are prepared so that they will react to become diazonium compounds ready for the subsequent ‘coupling’ vessel where they form the final crude pigment or ‘azo dye’. The basic starting materials for these compounds are hydrochloric acid, water, sodium nitrite and the diazo component (usually aniline). To preserve the material quality during formulation, the mixture is kept cool by adding ice or via a cooling jacket. During this process, the level must be carefully monitored and kept constant.

Gas scrubber

Level and pressure measurement in gas scrubbers

Application

Carbon dioxide is separated from a gas mixture via two scrubbing columns. The gas mixture consisting of nitrogen, hydrogen and carbon dioxide passes through a gas pipeline into the first stage gas scrubber. An added solvent, usually aniline, binds with the carbon dioxide, which is then forwarded in liquid form to a gas scrubber or ‘desorber’ where it is “washed” out of the liquid. The process pressure is monitored during the absorption process, which takes place at high pressure and low temperature. The actual separation of the carbon dioxide from the liquid, however, is carried out under low pressure and high temperature, where the level of the liquid needs to be kept as constant as possible.

Flare knockout drum

Level measurement in the flare knockout drum

Application

The unrecoverable residues of oil and gas production are collected in the flare knockout drum and liquefied at high pressure. The recovered liquid, the condensate, collects at the bottom of the vessel and is disposed of. The non-liquefied gases are decompressed and burned in the flare system. To ensure efficient and safe operation of the vessel, the level inside must be very reliably measured.
