COAL CHEMICAL PROCESSING
Valve applications across coal conversion processes.
See how valve selection changes across coal preparation, gasification, syngas treatment and downstream chemical synthesis.
APPLICATION OVERVIEW
Four critical parts of the coal chemical process.
COAL PREPARATION & SLURRY FEED
Move abrasive feed without blocking the process.
Coal grinding, slurry preparation and feed systems deliver a consistent mixture to the gasifier under controlled pressure.
- Coal slurry tanks
- High-pressure feed pumps
- Slurry circulation
- Gasifier feed isolation
Hard particles, high solids content and pressure cycling accelerate erosion and can pack conventional valve cavities.
Full-port, wear-resistant valve designs reduce internal restrictions and protect critical sealing surfaces from the slurry path.

Hard-sealed full-port isolation for abrasive, solids-bearing media.
Metal-seated isolation for abrasive, hot or severe process media.
Low-profile non-return protection for high-pressure steam and process lines.
GASIFICATION & QUENCH
Isolate high-temperature, particle-laden process streams.
Gasifiers convert coal feed into raw syngas, followed by quench and initial solids removal under severe process conditions.
- Gasifier isolation
- Quench water lines
- Black water letdown
- Ash and slag handling
Temperature, pressure, flashing and entrained particles combine to create erosion, thermal shock and difficult shutoff.
Alloy materials, protected seats and engineered pressure-drop control are selected around each gasification duty.

Pressure-seal isolation for high-pressure, high-temperature service.
Metal-seated isolation for abrasive, hot or severe process media.
Reduced-flow-resistance throttling for steam and high-pressure duty.
SYNGAS CLEANING & SHIFT
Control corrosive and toxic process media.
Shift conversion, acid gas removal and sulfur recovery condition syngas before it enters downstream synthesis units.
- Shift reactors
- Acid gas removal
- Sulfur recovery
- Hydrogen and CO separation
H2S, CO, hydrogen and process chemicals require reliable containment and compatible body, trim and sealing materials.
Low-emission packing, corrosion-resistant trim and project-specified materials support isolation and control in toxic service.

In-line maintainable isolation for critical continuous-service pipelines.
Forged-body regulation and shutoff for high-pressure service.
Pressure-energized non-return protection for demanding high-pressure duty.
SYNTHESIS & PRODUCT RECOVERY
Support stable chemical production and product handling.
Clean syngas is converted into methanol, ammonia and other products, then separated, stored and transferred.
- Methanol synthesis
- Ammonia synthesis
- Product separation
- Storage and loading
Continuous operation and varying process media demand tight shutoff, predictable control and maintainable valve packages.
Gate, globe, check, ball and control valves are assigned by isolation, throttling and backflow-protection function.
