Some of Our Technologies and Expertise

Our technologies are capable of meeting the most stringent gas emission requirements with low operating and maintenance costs, including:

  • Dust and Fume removal and collection systems;
  • SOx, NOx, Cl2 and other halogens and sulphur based components using absorption, adsorption and reactive scrubbing;
  • Heavy metals removal;
  • VOC’s and other organics including PCB’s;
  • NH3 and Amines;
  • FGD Systems including waste liquor recovery and regeneration tailored to each specific application.

Kemplant  offers complete custom-solutions to address our clients air pollution abatement needs. We have been designing, constructing and supplying gas scrubbers for diverse areas and applications for more than 30 years.  Our technologies are frequently reviewed and augmented, ensuring we remain current with all advancements in this field.

Kemplant’s novel and conventional effluent and waste water treatment technologies have been applied and operated in a cross section of various industries, including:

  •     Mining and Mineral beneficiation;
  •     Iron, Steel and Coke;
  •     Chemical and Petrochemical;
  •     Pharmaceutical, Detergents, Pesticides and Paint;
  •     Pulp and Paper;
  •     Hazardous Waste sites;
  •     Textiles

Technologies applied for the successful treatment of effluents and the recovery of water of varying quality to client’s requirements, are tailored specifically for the particular effluent or waste water being treated.

Solids contained in effluents are removed using conventional techniques such as agglomeration and gravity sedimentation (clarifiers, settlers), filtration (sand beds, cloth, disks, screens and other media) or mechanical separation (centrifuges).

Brines requiring the removal of dissolved components are processed using evaporation, crystallisation, chemical reactive precipitation, neutralization and softening.

Water requiring polishing to specific contaminant quality standards or primary processing for further downstream treatment, is treated using ion-exchange, activated carbon absorption and adsorption, membrane processing (reverse osmosis, electro-dialysis), ultra-filtration, re-mineralisation and pH adjustment.

Effluents containing high levels of oils and greases generally emanating from steelworks, oil refineries, petrochemical plants and natural gas processing plants are treated using mechanical devices such as oil skimmers, API Separators, DAF, DGF, settling decantation or chemical sedimentation and coagulation, for further downstream solids/liquid separation processing and COD/BOD absorption or destruction.

Evaporation and Crystallisation are basic chemical engineering processing unit operations with well-established and proven technologies.

Kemplant has, over the last 30 years, expanded, improved, optimised and modernized these technologies based on plant experience of over 30 installations, utilizing advanced computer simulation, modelling and mass-heat transfer CAE and CFD software together with piloting and in-house testing.

Evaporator types, augmented with advanced know-how supplied by Kemplant, are:

  • Film Evaporator including Falling Film, Climbing Film, Thin Film, Applied Film and combinations of these;
  • Natural Circulation Evaporators, short tube vertical or horizontal;
  • Forced Circulation Evaporators which can be with integrally mounted top or bottom heaters, single pass, external mounted heaters, multiple or single pass, vertical or horizontal and any number of variations of the above;
  • Mechanical Vapour Recompression utilising electrical power as energy source with high recovery efficiencies;
  • Steam Thermo Recompression for maximising steam usage efficiency;

Evaporator design includes materials of construction optimised for cost and technical compatibility, minimizing heat exchange surface scaling, high, medium and low (vacuum) pressure operation, energy sources such as steam, electrical power, waste heat utilization and recovery, plus other.

Crystalliser types are numerous and the correct choice depends on the particular process parameters and the desired results.  Kemplant’s technological scope covers the complete range of crystalliser types and variations thereto.

There are five basic modes of crystallisation:

1. Evaporative, where supersaturation is generated by vaporization of solvent
2. Cooling/Freezing, where supersaturation is generated by cooling a solution through direct or indirect heat exchange
3. Vacuum cooling, where supersaturation is generated by adiabatically flashing feed solution at a lower temperature and inducing crystallization   by cooling and vaporization of solvent
4. Reaction, where supersaturation is generated as the product of a chemical reaction
5. Salting, where supersaturation is generated by the addition of a third substance to cause a reduction in the solubility of the solute

Crystalliser systems for any of the above crystallisation processes are custom designed to suit the particular process requirements and material being crystalised.

Crystalliser units include Forced Circulation, Mix-bed Semi-growth, Growth type using Elutriation and/or DTB, “Oslo”, Cooling or Freezing and Melt.  Crystallisers can be batch, semi-batch or continuous.

Our experience and expertise in the Chemical Engineering industries, coupled with a strong technical ability, allows Kemplant to spearhead and assist with the development of new processes utilizing computerised simulation, modelling, in-house test work and the provision and operation of pilot plant(s), to effectively prove and scale-up processes, bridging the gap between new technologies and application thereof at industrial scale.

Using the latest technologies and computational software, Kemplant is able to create, virtualize, run and subsequently optimize new process designs plus model and simulate existing process plant installations to analyse and resolve problems, debottleneck, increase safety, increase plant capacity, decrease operating costs and generally improve and enhance the viability of existing processes and plants.

Some of the software used is COMSOL, HYSYS, AFT Impulse, ANSYS, AutoPipe and other.

Modelling and simulating new or existing processes, although initially intrinsically complex and difficult to setup, once established, enables a vast array of optimisation to be carried out at a minimal cost to client and requiring no modifications to be made to existing plant or processes.  Any changes are only implemented once they have been thoroughly tested under simulation and modelling modes.

Modular Plant design, assembly, construction and commissioning, customized to client’s specific requirements and allowing re-configuration for changes in processes, product specifications or operation, is undertaken by Kemplant’s process innovation and design team.

Smaller, easily maneuverable and configurable plants are considered as the next step in modern chemical engineering applications, allowing plant and equipment to be re-used, transportable to various sites, compatible and adaptable to a range of processes and technologies, energy efficient, environmentally friendly, safe and fully customisable.
