Chemical Handling Systems
Chemical Handling Equipment Systems designed by A.H. Lundberg range from specialized distillation columns, hot gas quenchers, and mixer/reactors to various by-product recovery systems.
We offer a full range of engineering services to evaluate and redesign existing systems, updating as necessary to meet the most current plant standards of our customers.

Turpentine Recovery
Soap Recovery
Specialty Equipment
AHL supplies a range of chemical reactors and handling systems to efficiently and safely handle, off load, and store most chemicals used in process industries.
Equipment offerings include: white liquor oxidation systems; mixers and reactors; specialty pressure vessels; distillation columns; sulphur dioxide and chlorine vapourizers; chemical handling systems, and quench vessels.
Turpentine Recovery
Crude Sulphate Turpentine (CST) recovered from the kraft pulping process is typically used as a fuel or sold as a byproduct. 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.
Soap Recovery
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.
Addressing 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.
