MEASUREMENTS

On-line measurement of the salt concentration in crude oil plays an important role in the

crude oil chain, from the well head until entering the crude distillation unit. The MOD-4100 S

is on-line salt in crude oil analyzer, which is designed to provide real time analytical data of

the salt content in crude oils. Its technology is based on ASTM D 3230, an electrometric

methods. This method determines the salt concentration in crude oil by measuring its

conductivity, when dissolved in a s mixture of an aromatic and an alcoholic solvent.

SALT CONTENT IN CRUDE OIL (PTB or mg/L)

Provides online critical data of crude oil qualities.

Provides on-line data about the salt content at the

oil-well head

Provides on line data of the salt content prior and

after shipment

Provides on-line data of the salt content after

blending

Provides on-line data of the salt content before

entering the desalter

Indicates the desalter efficiency.

Allows on-line optimization of the desalter process

conditions.

Reduces water, chemicals and energy consumption in the desalters.

SALT IN CRUDE OIL

Crude oils and crude oil blends have

different physical and chemical

properties, which depend primarily

on their place of origin. Even if

originated from the same location,

fluctuations in 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

content. On line information of the salt

concentration in crude oil is critical to

prevent corrosion, fouling and plugging

of the pipelines and production units of

the refinery.

\

The MOD 4100 S is an on-line salt in

crude oil process analyzer, which is

designed to provide real time analyses

of the salt concentration in crude oils,

expressed in PTB or mg/l. Its technology

is based on a wet chemical

electrometric conductivity method.

Incorporation of the MOD 4100 S

before, between and after the desalters

provides an effective tool to operate the

desalter at maximum efficiency and at

lowest cost for reducing the salt content

to its minimum, before the crude oil

enters into the CDU.

The importance of measuring on-line the

salinity of crude oil is not restricted to

the refinery operation only, but is also

essential from a commercial point of

view.

The salt content in crude oil is one of the

parameters that will have influence the

crude oil quality and by that its

commercial value.

The MOD 4100 S enables to check the

salt in crude quality before and after

loading and unloading, during

transportation from the oil-well to the

terminals, during shipment and during

transportation from the terminals and

tank-farms to the the refineries.

The MOD 4100 S salt in crude analyzer has

been designed to perform quantitative

analyses of the salt concentration in crude

oils. Based on ASTM D 3230, the MOD 4100

S applies a wet chemical electrometric

method, which determines the salt

concentration of crude oils through

measuring its conductivity in solution.

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.

This is fully automatically and accurately

performed by an electronic system that

controls a set of precise pumps and valves.

An accurate amount of a sample of crude oil is brought into the measuring cell. Precise volumes of solvents are accurately added to the cell content and mixed with the sample. The salt concentration is determined by measuring the conductivity of a the crude oil sample dissolved sample in fixed amount of diluents. When the measurement are terminated, the cell content is discarded, and the system flushes rinses and cleans itself automatically.

Error messages will be displayed in any case

of a faulty status .

Samples can be taken from vessels, pipes

vessels, bypasses or pressure pipes.

According to that a sampling system is

designed to feed the analyzer with a sample

at optimized conditions, to guarantee the

provision of precise analytical results.
