calcium carbide plant in the world
Hatch technologies implemented
per year of calcium carbide production
of high-grade energy recovery
- Conveying, cooling, and cleaning the toxic syngas produced by the QSLIC furnaces risks explosion or fire. Even a minor leak can result in poor workplace hygiene.
- Safely treat large volumes of gas using a completely "dry" process due to regulations regarding limited water availability and restrictions on secondary pollution.
- Gas treatment systems had to directly couple to a kiln burner as part of a separate downstream process.
- Balancing the furnace gas supply with user demand gave rise to unique control requirements.
- Entire process and plant design developed, from feasibility to basic and detailed engineering, procurement, construction, commissioning, and start-up assistance.
- Created a combustible gas-treatment process that addresses the smelter's associated health and safety issues. The installation was the most comprehensive solution available, delivering the safest operation with both passive and active monitoring systems.
- Three patented technologies incorporated: inherently safe 100% positive pressure gas handling; sealing technology for high-temperature ductwork flanges; and a dust-wash system that reduces toxic emissions.
- Many "clean plant design" principles incorporated to meet strict requirements for workplace hygiene.
- Met the most stringent global environmental emission limits for air, water, and solids; the best dry gas treatments in the Far East combined with the highest Western standards for reliability and safety.
- The high quality of dry gas produced is more compatible with virtually all end users, resulting in better energy recovery than conventional wet cleaning systems.
- The suite of features and equipment is fully scalable and can be tailored to specific requirements of other smelting applications based on requirements.
- Each feature can be considered an individual module, within which a customized system may be assembled.
