Measurement Solutions for Petrochemical Plants
Analytical and engineered instruments for feedstock quality, sulfur control, reactors and columns, fired equipment, water systems, gas flow, and materials verification.

Connecting feedstock, process, utility, and product measurements
Petrochemical plants operate interconnected reaction, separation, heating, compression, storage, and utility systems. Measurement performance affects feedstock acceptance, process stability, product consistency, equipment protection, wastewater treatment, and maintenance decisions.
Blue Dragon Technology supports these requirements with sulfur analyzers, water-quality instruments, elemental analysis, tube-skin and multipoint temperature assemblies, and industrial gas-flow meters. Application review focuses on the process stream, expected composition, measurement location, installation constraints, response-time requirement, and lifecycle support needed by the plant.

Explore →Industry questions.
How do petrochemical applications differ from refinery applications?
Petrochemical plants often place greater emphasis on reaction profiles, feedstock consistency, catalyst-sensitive streams, polymer or chemical product quality, and complex utility integration. The exact measurement basis must be reviewed by unit and stream.
Can multipoint temperature systems be customized for reactors or columns?
Yes. Sensor count, insertion length, process connection, support arrangement, materials, routing, and termination are engineered from the vessel design and operating conditions.
Which water measurements are commonly reviewed?
TOC, oil-in-water, and turbidity may be relevant to process water, cooling systems, treatment performance, reuse, and effluent monitoring.
Can elemental instruments support maintenance and incoming inspection?
Yes. Handheld or benchtop XRF can support material identification, alloy verification, incoming inspection, and plant laboratory workflows, subject to the required calibration and matrix.
