Chemical Handling Equipment
Chemical Handling Equipment designed by A.H. Lundberg can range from specialized distillation columns, hot gas quenchers, mixer/reactors to various by-product recovery systems.
System components may be used to upgrade or expand existing systems.
We offer a full range of engineering services to evaluate and redesign existing systems, as necessary to meet the most current plant standards of our customers.
AHL supplies a range of chemical reactors and handling systems to efficiently and safely generate the process operation required.
Equipment offerings:
- White liquor oxidation
- Mixer and reactor
- Specialty pressure vessel
- Distillation column
- Sulphur dioxide and chlorine vapourizers
- Chemical handling systems
- Quench vessel
We provide process equipment to handle, off load, and store most chemicals used in process industries, including sulphuric acid, sodium chlorate, chlorine, sodium hydroxide, pril sulphur and molten sulphur.
Crude Sulphate Turpentine (CST) recovered from the kraft pulping process is typically used as a fuel or sold as a by-product. CST dumped to sewer in large quantities can upset the effluent treatment system (it is toxic to the bugs in high concentrations).
CST is toxic and extremely flammable so caution must be used when handling it.
Pulp mill foul condensates containing high levels of CST should be recovered and treated in the turpentine recovery system.
In kraft softwood mills, tall oil soap is a valuable by-product as well as a toxin in the wastewater treatment system. Thus it is necessary to properly manage foam and soap within the mill.
Managing this issue requires a number of steps including the handling and deaeration of foam, separation of soap from liquor, and the separation of liquor from soap. Once the soap is separated from the system, it should be kept separate and not remixed with the liquor.
New technologies emerging from the by-product recovery of black liquor soap include conversion of the soap to bio-diesel fuel (SDRF process) and the extraction of other valuable by products such as sterols.
