SALT AND TAN IN CRUDE OIL Crude oils and crude oil blends have

different physical and chemical which

depend on their place of origin. Even

if originated from the same location,

fluctuations in the physical properties

are a common phenomenon. Several

quality properties have impact on the

cost and ability to process the crude oils

in a certain refineries. Among these the

salt and TAN acidity content. On line

information of these data is critical in

the prevention of corrosion, fouling and

plugging of the pipelines and production

units of the refinery.

The MOD-4100 TS is on-line salt and

TAN in crude oil analyzer is designed to

provide real time data of these critical

physical parameters. Its technology is

based on wet chemical methods, based

on acid/base titration and electrometric

conductivity methods.

Implementation of these analyzers

enables to take immediate steps in

desalter and CDU process parameters to

reduce the impact of the salt content

and the TAN to its minimum.

Incorporation of the MOD-4100 TS

before, between and after the desalters

to operate the desalter at maximum

efficiency and at lowest cost to reduce

the salt content to its minimum before

entering the CDU.

The importance of measuring on-line

crude oil parameters is not only

restricted to the refinery operation, but

is also essential from a commercial point

of view.

It enables to check the crude quality

before and after loading and unloading,

during transportation from the well to

the terminals, during shipment and

during transportation from the

terminals and tank-farms to the

consumer. Furthermore, it provides the

crude analyzers with an effective tool

for crude blending, allowing to on-line

changing of the ratio between different

crude qualities to enable the formation

of cost saving crude blends. It is a

effective tool in maximization of low

cost heavy and opportunity crude in

blend, without loosing its requested

physical properties. of heavy and

opportunity crude.

The MOD-4100 TS analyzer has been

designed to perform quantitative analyses

of the salt concentration and / or the TAN

content. It is a combination of two different

wet chemical methods in one analyzer. The

salt measurement is performed according

to the ASTM 3230 adapted electrometric

method, while the TAN is analyzed

according to the ASTM D-664 adapted

potential titration method.

Measurement Procedures

The analytical procedure starts with

sampling of the process stream and

bringing a well defined quantity of the

sample into the analyzers measuring cell. In

case of the salt analyses a common titration

vessel equipped with a pH electrode, and

on case of the salt analyses in an ASTM

based measuring vessel.

This is fully automatically accurately

performed by an electronic system that

controls a set of pumps and valves.

After introducing the sample in the

measuring chamber, solvents and reagents

are accurately added and mixed with the

sample and the sample is measured with

respect to the ASTM described method.

After termination of the measurement

reagents are discarded, and the system

rinses/cleans and flushes itself

automatically.

Error messages will be displayed in any case

of a faulty status and/or exceeding the

specification values

Samples can be taken from vessels, pipes

vessels, bypasses, pressure pipes. According

to that a sampling system is designed to

feed the analyzer with a sample at

optimized conditions, which enables the

provision of precise analytical results.

The MOD-4100 AS salt analyzer is equipped

with an automatic calibration system.

Users Benefit

The MOD-4100 TS provides a high

quality salt and TAN in crude oil

determination in one instrument
