ZELENTECH – IN BRIEF

ZelenTech is a fluid measurement company specializing in Watercut Monitors (also known asBS&W, OWD, WFM or Water in Oil Analyzers) for Oil & and Gas Industry as well as Water In OilMonitors for lubrication systems in Heavy Machinery and Marine applications.

ZelenTech is investing heavily in research and development, building excellence on the stablefoundation of previous product lines. Capitalizing on the technical know-how and marketknowledge of its founders, the ZT-100 Series is now successfully deployed in a number ofdifferent industry applications around the world.

ABOUT US

The ZelenTech ZT100 Watercut Meter is rooted in the Capacitance

Measurement Technology originally developed by Swedish entrepreneurs

Hans and Jorgen Lindahl 17 years ago resulted in a device with top of the

line electronics backed by decades of field experience.

With the ZT100 Watercut product line ZelenTech offers a flexible and fully

customizable line of water cut meters unprecedented in the industry. We

build units that match your system.

The product range covers measurement devices for Watercut (Oil & Gas)

and Water In Oil Monitors for Heavy Machinery and Marine Applications. The

measurement devices are complemented with equipment for presentation

and data collection as well as Stream Conditioning.

The company also specifically targets custom designs solutions for its clients.

The foundation of the company and its success is due to the emphasis

placed on investigating and understanding customers' needs in order to

meet and exceed expectations both technically and economically.

THE TECHNOLOGY

CapacitanceCapacitance technology has been used bythe oil industry to measure water cut for almost50 years. The technology exploits the significantdifference in dielectric properties between oil(~ 2) and water (~80). The continued successcomes not only from the fact that capacitancetechnologies was first on the market, but thefact that it does a pretty good job in the mostcommon ranges, this at reasonable prices.

The net capacitance of the 2-phase media is measuredby transmitting a radio frequency voltage across thesensing elements. The net capacitance is directly relatedto the water cut. Good correlation can be reachedprovided the dry oil capacitance as well as the watercapacitance is known. Capacitance goes up withincreasing water cut and down with decreasing watercut.

Backed by a long history and continuous developmentthe capacitive instruments have the key advantage ofbeing a stable (and proven) measurement technology.Simple design, insensitivity to water conductivity andability to handle a majority of oil patch applications areother key features. It is a common misconception thatcapacitive instruments are limited to the lower segmentof the non-linear capacitance vs. water cut responsecurve. Recent developments have brought forwardcapacitance instruments able to measure up to inversion(*) under unfavorable conditions and all the way to 100%water cut under favorable water conditions.

OVERVIEW

Water contamination in oil based fluid can cause numerous problems such as loss of revenue, additivedepletion, oil oxidation, etc… these problem can be prevented by proper online monitoring, whenspot sampling is in sufficient to represent the bulk of oil in processes.

Are we missing the big picture?

CHALLENGES – WATER FORMS

Dissolved WaterDissolved water contamination is the least harmful

of the three types of water. Dissolved water is a functionof the environment- Relative humidity, temperature,and oil type will normally determine what dissolvedwater content will be. (Ie. Dissolved water does notaffect lubricity).Emulsified Water

Emulsified water is water that has been mixed,homogenized and/or mechanically emulsified in the oilto form extremely strong emulsions. Strong in the sensethat gravity or other devices will not work in separatingthe two phases. Emulsified water is capable of reducinglubricity.Free Water

Free water is free to separate and settle to the baseof the reservoir or the pipelines. (ie. Free water is themost damaging, because it can displace Lube oil andallow metal to metal contact of rotating equipment).

It is a known fact that water in oil can exist in three known forms.

We measures ALL of them, simply.

CHALLENGES – PROCESS CONDITIONS

Illustrates the flow regimes we can

encounter in horizontal two-phase liquid

flow. Stratified flow has the strongest

tendency to occur in downhill or horizontal

flow with relatively small water and oil flow

rates if not mixed in prior.

ESSENTIAL TO UNDERSTAND

Static Mixer

Proper mixing of waterand oil is the key tosuccessful measurement.

BRIEF REFERENCE

LACT SystemUSA

WHAT DETERMINES A GOOD WIO

Elbow

Straight & bending

4 Criterias:

1. Proper working analyser

2. Selecting of the correct installation location

3. Homogenous, well-mixed condition

4. Ability to correlate/validate against standards- sampling / lab testing

Correct installation is essential.-performance & precision of the measurement.-cost of installation normally costs more than the analyser.

Do it right, the first time!

OUR PHILOSOPHY

NO measurement can be valid without a total representative measurement!

Spot measurement & inadequate sampling can never be considered as representativeness of the process =

Provide a total installed cost effective solution to the best measurement of % or ppm of water in oil content.

We believe that present method in general does not ensure a true sample & representation of what is flowing in the actual main process.

Long term Return-On-Investment (ROI) cost should be considered much more over ‘quick-fixes’.

It has to be simple.
