Custody transfer is a process that gets the most usage in the oil and gas industry.  The petroleum industry has a significantly strong demand for custody transfer static mixers.  They transfer raw or refined petroleum between two or more tankers.  There are many challenges when doing this, and a custody transfer mixer can alleviate many of these problems effectively.  Without the right tools and mechanisms, it is hard to achieve the right quality of refined petroleum.

What is a Custody Transfer (CT) Mixer?

Custody Transfer (CT) Static Mixers are designed to meet the special requirements and standards for custody transfer/fiscal measurements.  It is essentially a low-pressure drop static mixer.  Thus, the primary purpose is to ensure that the bottom, sediment, and water obtain thorough dispersion throughout the crude oil stream.

The transfer mixer’s specifically main objective is to optimize the accuracy of crude oil sampling.

How Does a CT Static Mixer Work?

The custody transfer static mixer works by solving issues such as wall streaming and also by assuring uniform distribution, which results in reliable sampling.  It has inverted vortices which sends some of the flow back upstream within the mixer apparatus and this reduces spies of bottom sediment and water concentration.

Installation of a Custody Transfer Static Mixer?

A CT mixer is installed upstream of the crude oil sampling transfer line.  Such as ship and tank truck terminals or refinery transfers.  The custody transfer static mixer installation in either vertical or horizontal pipeline.  If it is placed in a horizontal pipeline, it acts as a ramp, pushing the bottom water into the crude to facilitate homogenous mixing.

Benefits of a Custody Transfer Mixer

The goal of a CT mixer is to deliver fast results and saves in testing errors, which is an industry-wide problem plaguing profitability.

Komax’s Custody Transfer Static Mixer in Comparison to Others

An important feature of the Komax CT mixer is the addition of the last mixing element that cancels all the axial rotation of the flow downstream of the mixer.  Violent rotation of the stream will cause the centrifuging problem of the water to re-occur.  The automatic sampler is located two to four pipe diameters downstream of the mixer.  The resulting samples provide highly reliable net crude oil measurements.  It gives surprisingly consistent extraordinary results.

Komax particularly understands site-specific smart mixing, avoiding overmixing, or emulsifying, and produces a very uniform distribution and droplet size of water in the custody transfer metering process.

The Komax CT mixer has seen over ten thousand different installations around the world. And it has proven to be a gigantic improvement over the previous methods. If you have questions about how the mixer will help your company, let one of our representatives give you answers.
