Welcome to Process Plant Technology (PPTech)

Process Plant Technology (PPTech) is a South African technology company, based in Johannesburg.

Process Plant Technology specialises in the turnkey supply of engineered systems and plants into the chemical, pulp and paper, mining, minerals, food and beverage industries. The majority of these plants are designed and manufactured locally. The emphasis is on process engineering, specifically heat and mass transfer operations.

Evaporation		Crystallisation
	An evaporator is used to evaporate a volatile solvent, usually water, from a solution. Its purpose is to concentrate non-volatile solutes such as organic compounds, inorganic salts, acids or bases.		Crystallisation, as a unit operation, embraces the concepts of producing a pure crystal within a magma containing impurities. The design of crystallisers is strongly influenced by the characteristics of each material handled.
Dryers		Distillation and Absorption Plants
	Process Plant has the capability to offer Flash, Fluid Bed, Rotary and Spray dryers either within crystalliser systems or as stand-alone units.		Process Plant Technology designs and supplies distillation plants to recover solvents and specilised organic compounds. Reference plants include methanol, ethanol, turpentine and furfural recovery.
Scrubbers		Filtration
	We offer a range of wet scrubbers to meet the most arduous of duties in difficult applications. These include venturi, impingement tray, packed bed design and filter element type of scrubbers		Filtration is a vital unit operation throughout the chemical industry and Process Plant Technology has a particular strength in selecting appropriate equipment and system development.
Membrane Processes		Air Cooled Heat Exchangers
	Membrane processes are commonly used in conjunction with evaporation to provide a primary concentration of process streams, including effluents. In conjunction with specilaised partners we can offer complete systems		Process Plant technology has access to specifically designed air cooled heat exchangers manufactured in Asia. These units are designed on a case-by-case basis for each application considered.
Mixed Brine and Effluent Applications		Zero Liquid Discharge (ZLD) Plants
	Process Plant Technology have been involved with almost fifteen different installations where mixed and or effluent brines are handled. In many of these plants, valuable intermediates are recovered as well as the water to offset the operating cost of the plant.		Increasingly, legislation and industry demands a zero liquid discharge with a solid product that can either be sold or more readily dumped in a sealed landfill.
