Dynamic Scale Loop (Differential Scale Loop)

Production engineers are responsible for the design, operation and efficiency of water handling systems in which thermal, pressure or chemical changes lead to scale deposition.

Dynamic Scale Loop with 10,000 psi max pressure

DSL System with Cooling & Heating Capability

6,000 psi System

Oven with Fan and Window, Filter/Core Holder

In-line pH Probe

Our dynamic scale loops provide an accurate, reproducible and fast methods for selecting and quantifying the most effective means of controlling scale deposition under dynamic pipeline conditions.

Description

The instrument is suitable to simulate process or reservoir temperatures of up to 280 °C and pressures of up to 1,000 bar (14,500 psi). Higher ratings can be provided if required. An integrated pH probe ist available. The system is very recommended where effects of pressure on scaling tendency are to be studied, and especially for examining the deposition of anhydride under dynamic conditions.

This instrument offers a variety of advantages:

Automated test and cleansing routines programmable
Determination of minimal inhibitor concentration: manual or with two automated procedures
Extended number of brines/inhibitors with optional mixing bank
Optional pH / conductivity probe with automated data logging
Optional pipeline cooling
Several PEEK/Monel/Hastelloy options for high corrosive applications

The test pipelines are easily exchangeable with standard connections. The test pipelines have a defined inner roughness, which is highly important to assure reproducible test results.

Applications

Besides manual operation, our scale loops offer 2 different automated test methods:

Tube Blocking Test (TBT): The scale inhibitor concentration is decreased along a defined curve until scale is detected.
NEW! Scale Equilibrium Test (SET): The scale inhibitor concentration is increased until a scale equilibrium is achieved.

Applications:

Scale inhibitor development and testing
Scale inhibitor efficiency tests
NEW! Corrosion tests on test sheets and test rods
