Operating principle

The Mirmorax Oil-in-Water analyzer is based on an ultrasonic measurement technique which is a direct measurement on individual acoustic echoes that are characterized using advanced signal processing.

A highly focused acoustic signal is transmitted directly into the produced water flow. The reflection and absorption of the signal provide a wide range of accurate measurements. In the focal region, individual solids, oil droplets and gas bubbles will reflect the acoustic energy and each reflected signal will hold particle specific information.

Based on a large number of direct measurements, the monitor calculates mean particle size for oil and sand. The size distribution and also the number of particles are used to calculate corresponding concentration values.

Important process information as salinity and temperature are measured and used as input for calculation of oil concentration.

Model features

The primary outputs, real-time oil concentration and 24H average oil concentration, are displayed numerically in the digital display integrated in the analyzer. The analyzer performs self-diagnostics and auto calibration. Mirmorax Oil-in-Water RTG100 primary outputs are real-time oil concentration and 24 hours floating average oil concentration.

These outputs are displayed numerically in the digital display integrated in the analyzer. Additional data available as Modbus addresses are droplet size, water density and temperature.

The analyzer performs self-diagnostics and auto calibration. Recommended calibration range is 0-100 ppm.

Design

The by-pass Oil-in-Water analyzer is our newest design and a “Ready-To-Go” solution with an easy and low-cost integration. The standard interface is a 1” NPTF inlet and outlet to transport the flow through the flow cell, however fittings to match smaller sizes can easily be added.

A pressure drop of minimum 0,2 barg will allow for the flow to be returned to the main flow after passing the measurement element in the flow cell. Alternative return is a closed or open drain system.

The measurement element is directly connected to the electronics placed in a stainless steel 316 housing with EX classification Zone 1. The total weight is approximately 20 kilos. Two pigtail cables of 10 meters are included for the power supply and output signals.

The analyzer can be supplied in a customized mounting rack with an integrated Mirmorax Automatic Cleaning system to ensure clean ultrasonic transducer and reflector at all time.

Operating Principle

The Mirmorax Oil-in-Water analyzer is based on an ultrasonic measurement technique in which individual acoustic echoes are characterized using advanced signal processing.

A highly focused acoustic signal is transmitted directly into the produced water flow. The reflection and absorption of the signal provides a wide range of accurate measurements. In the focal region, individual solids, oil droplets and gas bubbles will reflect the acoustic energy and each reflected signal will hold particlespecific information. Based on a large number of direct measurements, the monitor calculates full size distributions for oil and sand. The size distributions are used to calculate corresponding concentration values.

Important process information as salinity and temperature are measured and and presented in the Oil-in-Water graphical user interface. The analyzer performs self-diagnosing and auto calibration and automatic flushing.

Model Features

The Mirmorax Subsea Oil-in-Water analyzer is developed from the 3rd generation ultrasonic analyzer. Model SOIW 2500 is specially developed to manage the lower range, 0-2500 ppm of oil and particles with highest accuracy and at the same time deliver classification of particles and size distribution.

This is especially suitable for re-injection applications, where knowledge on this is essential for reducing ppm levels and optimizing the separation process.

Design

The Mirmorax Subsea Oil-in-Water analyzer consists of two ultrasonic probes in series in a spool piece. The retrievable electronics canister has two redundant electronics, one for each probe.

The system has a built in flushing system which can use any available liquid for flushing with a 20 process overpressure. This gives a design life of 25 years for the overall system. The system has a design pressure of 690 bar and is designed for 3000 meter water depth.
