Chemical plants require reliable measurement of flow, pressure, level and temperature across reactors, storage tanks, pipelines, heat exchangers and utility systems. Process conditions can vary significantly, from corrosive liquids and chemical vapors to high temperatures, high pressures and hazardous-area environments.
FUGUI Automation supplies industrial process instrumentation for chemical processing applications, including pressure transmitters, differential pressure transmitters, flow meters, radar level transmitters, ultrasonic level instruments, RTDs, thermocouples and water quality sensors.
Process Measurement Challenges in Chemical Plants
Selecting instrumentation for a chemical process requires more than simply matching a measuring range. The process medium and installation environment must be evaluated together.
Important considerations include:
- Chemical composition and concentration
- Corrosiveness
- Process temperature
- Process pressure
- Flow range
- Tank height
- Fluid conductivity
- Viscosity and density
- Vapor, foam or agitation
- Wetted-part materials
- Hazardous-area requirements
- Output and communication protocol
The correct instrument should be selected according to actual operating conditions and the required measurement function.
Flow Measurement for Chemical Processes
Flow measurement is commonly required for raw materials, process liquids, chemicals, cooling water, wastewater and utility systems.
Depending on the medium and process conditions, suitable technologies may include:
Electromagnetic Flow Meters
Electromagnetic flow meters are commonly considered for conductive liquids and can be suitable for many chemical and wastewater applications.
Coriolis Flow Meters
Coriolis meters can provide mass flow measurement and may also provide density information, making them useful for applications where mass-based measurement is important.
Vortex Flow Meters
Vortex meters may be considered for steam, gas and certain liquid applications where the process conditions are appropriate.
Pressure Measurement
Pressure transmitters and differential pressure transmitters can be installed on:
- Chemical reactors
- Process pipelines
- Pumps
- Filters
- Heat exchangers
- Storage vessels
- Gas systems
- Utility lines
For corrosive or high-temperature media, diaphragm materials, wetted parts and remote seal configurations should be evaluated carefully.
Level Measurement for Chemical Tanks
Level measurement is required for chemical storage tanks, reactors, mixing vessels and process containers.
Radar level transmitters can provide non-contact measurement and may be suitable where direct contact with the process liquid should be minimized.
Selection should consider:
- Tank height
- Process temperature
- Process pressure
- Product dielectric properties
- Foam
- Vapor
- Agitation
- Nozzle position
Temperature Measurement
RTDs and thermocouples can be used for reactor, pipeline, tank, heat exchanger and utility temperature measurement.
The selection should consider:
- Temperature range
- Sensor accuracy
- Response time
- Insertion length
- Process connection
- Thermowell requirements
- Material compatibility
