Custody Transfer Mixer
2Pages

INLINE STATIC/MOTIONLESS MIXERS Komax Custody Transfer or CT mixers are installed upstream of the sampling point in a crude oil transfer line. They assure that the bottom sediment and water — B,S & W — is thoroughly dispersed throughout the crude oil stream. An even water droplet size and distri- bution occurs over a wide flow range. This means that a truly representa- tive sample is taken by the automatic sampler. Komax CT mixers are install- ed in petroleum product transfer lines such as ship and tank truck terminals or refinery transfers in combination with a LACT unit. CT mixers are supplied with weld neck flanges or ends prepared for welding. For ease of installation Komax CT mixers are supplied complete with two inch flanged port for the automatic sampler con- ection. Dimensions for this style and model numbers are listed below.

This photograph was taken of clear mineral oil having the same viscosity and density as medium crude. 1% dyed water was added. The picture shows the trailing edge of a CT mixer element that has been fitted with three 750 micron diameter wires to allow estimates to be made of water droplet size. Note that the water droplets are uniform in size and distribution. They are typically less than one tenth the size of a sampling probe orifice guarantee- ing that a truly representative sample can be taken. The test velocity is 2 ft/sec. At higher velocities, uniform water droplets of a smaller size...
