Vaisala K PATENTS® Refinery Process Refractometer PR-23-RP

The Vaisala K-PATENTS Process Refractometer PR-23-G is a heavy-duty refinery model designed to meet the unique requirements of the refining and petroleum industries. Typical applications include accurate liquid concentration measurements, such as sulfuric acid in alkylation, ethylene glycol, amine, or potassium hydroxide (KOH) in gas processing, multi-product (crude oil, fuel oil, diesel) interfaces in trade handover operations, and lubricating oil processes in refining.

Refractometer sensors are mounted in the process directly through welding studs or through 1 inch, 2 inch, or 3 inch cross-flow tanks. The PR-23-RP operates accurately and reliably in harsh refinery conditions due to the rugged sensor, innovative non-soldered sensor body, and self-cleaning or optional automatic cleaning system functionality. Provide essential safety and hazardous area authentication for hazardous areas.

The measuring range covers 0-100% (by weight). The accuracy is usually ±0.1 % bw and the measurements are automatically temperature compensated. Low and high concentration alarms can be configured. Due to the digital sensing technology, even a large number of suspended solids, bubbles, or color changes do not affect the measurement or accuracy.

Each sensor is equipped with a calibration certificate that compares a set of standard liquids to the actual sensor output. Calibration and accuracy can be verified in the field using certified refractive index liquids and Vaisala documentation procedures.

feature：

1. Integrated refractometer sensor main structure, no weld. Mount directly through welded studs, or through 1 inch, 2 inch, or 3 inch cross-flow tanks.

2. ASME Specification Compliance: The main physical features are designed to comply with ASME Section VIII Parts 1 and 2.

3. Universal calibration for each sensor: All sensors are freely interchangeable.

4. Complete measurement range nD 1.3200 -- 1.5300 refractive index, corresponding to 0 -- 100% weight.

5. Full digital system: particles and bubbles do not affect operation or accuracy.

6. Patented CORE-optics (US Patent No. US6067151) : no drift, no recaliphation, no mechanical adjustment.

7. Ethernet connection and remote panel for data logging and remote operation.

8. Process temperature range: -40°C -- 150°C (-40°F -- 302°F)

9. Fast process temperature measurement with built-in Pt1000 and automatic temperature compensation.

10. Dual connection: one transmitter can operate two sensors. A second sensor can be easily integrated later.

11. Easy field instrument validation in the user's own quality assurance system using standard refractive index liquids.

12. Self-cleaning or optional automatic cleaning system function

13. Provides intrinsically safe and dangerous area authentication.

main advantage：

Designed for harsh environments

The Vaisala K-PATENTS Refinery Process Refractometer PR-23-RP combines advanced CCD camera technology with a robust steel sensor probe. The probe is a non-welded sensor body model suitable for large pipeline and container installations. Designed for demanding process conditions, high temperatures, pressures and vibrations.

Special wetted component materials can be used in harsh environments and corrosive process fluids.

Installation and operation are simple and cost-effective

The process refractometer PR-23-RP is mounted in the main treatment line, side route, or container directly through a welding stud or through a 1 inch, 2 inch, or 3 inch cross-flow tank

Refractometers have no lights or moving parts that require regular maintenance or recaliphation. Users can simply "install and forget", resulting in a lower total cost of ownership.

Supply of industry expertise and engineering solutions, services, and vendor documentation

Refinery instrument models range from compact probe models for small pipelines and bypass lines to rugged heavy-duty long probe models for large pipelines, vessels and reactor units.

When standard models are not sufficient, consult the factory for engineering solutions, such as special wetting materials or custom installation accessories and process connectors.

Vaisala also provides a full range of start-up, commissioning and technical support services to our customers. Our oil and gas industry expertise includes providing extensive supplier documentation that is tailored and applied to each contract and customer's specific data requirements.
