The P-MAC system provides an accurate, reproducible and rapid method for selecting and quantifying the most effective means of controlling scale deposition under dynamic conditions. Routine results can be obtained within 20minutes.

APPLICATIONS
The P-MAC System is suitable for use with all oilfield scales such as Barium, Strontium and Calcium Sulphates and Calcium Carbonate and with other organic scales such as Oxalates.

MODELS AVAILABLE

• Model 2011 Standard single channel unit.
• Model 2011P The Model 2011P is the standard single pump module unit fitted with an integral pH meter to monitor effluent or mixed brine pH.
• Model 2012 The Model 2012 is a DUAL channel version of Model 2011. Consisting of two Pump Modules and a chart recorder which can display both channels on a single page.
• Model 2012P The Model 2012P is the DUAL channel unit fitted with a pH meter.

All Units consist of a standard set of Equipment.

Electronic Module
The Electronic modules consist of the following components :

1. Pressure Limit Control
2. Electronic Damping
3. Zero Offset
4. Stirrer Control
5. Digital Pressure Readout
6. Variable range 0 - 2v dc.

Pump Module
The pump module consists of a twin pump unit with speeds of 50 and 100 RPM. This allows flowrates of between 0 and 2 litres per hour to be achieved.
The two pumps allows different ratios of two brines to be mixed. If chemical dosing is also required further pump modules are necessary.

Chart Recorder
The standard unit consists of a single channel flat bed recorder providing variable span, speed and the option of digital function writing on the start of runs.

Computer Interface
All units have the option of interfacing to a computer for data acquisition and instrument control.

Heating Module

Water Bath
The bath is an eight litre standard water bath with a precision temperature controller. The test coil, 1mm ID SS capillary mounted on a Stainless Steel former, is located in the heating bath.

Oven
The Coil Oven incorporates the test coil together with two preheat coils for heating both brines.
