  - Process Simulation
    Process Simulation
    Logichem has a strong Process Simulation capability, which enables us to build accurate, predictive computer based models of processes.
    
    This is a particularly powerful tool used in the development of our alcohol distillation technology. Our Alcohol Distillation models have been validated on actual plant performance data, enabling reliable, predictive evaluations of alternative operating strategies in optimizing our designs to match Client requirements and constraints. This process simultaneously generates accurate Design Data establishing the basis for subsequent Equipment Design and Control Strategies.
    
    Application of this advanced design technique in the predominantly traditional Alcohol industry is the single most important factor that enabled Logichem to become the leading supplier to the Alcohol industry in Southern Africa.
    
    Process Simulation also plays a major role in the development of innovative technology. Examples are Logichem’s propriety CO2 Capture and Purification, and brewery water deaeration technology, installed at a number of breweries and alcohol distilleries in Africa.
    
    Process Simulation, coupled with our experience, is also the most powerful tool in trouble-shooting assignments, efficiency improving studies, and debottlenecking exercises conducted for Clients. It enables us to pinpoint problem areas and offer optimized solutions.

  - Design & Engineering Support for Client's R&D Programs
    Design & Engineering Support for Client's R&D Programs
    Scientists working in R&D cannot be expected to know what information is required by engineers to enable them to design equipment .
    
    A real example from our experience in a new product’s development by a client where process conditions and stream analysis were comprehensively researched and reported, no stream specific gravities (required for vessel sizing and pump power requirements) were measured. By the time this was pointed out, all samples had been disposed of. This could have been avoided by a comprehensive check list of design data requirements.
    
    As a design-focused engineering firm, Logichem can guide Client’s personnel in this respect.
    
    Our experience has shown that early involvement with Client’s R&D programs can ensure that the necessary data are identified and included in projected R&D outcomes to enable seamless progress to Process Development, Preliminary Equipment Design, Utility Requirements, Cost Estimating, Plant Layout and Plot Plan requirements to enable Feasibility Evaluation by the Client.

  - Developing R&D Results into Commercial Technology
    Developing R&D Results into Commercial Technology
    Surprising as it may seem, in large companies we have often come across a communication gap between R&D and Engineering departments. The scientists in R&D are not able to translate their results into an engineering language that can be understood and manipulated by Engineering to draw up flow sheets, equipment specifications, cost estimates, and project budgets.
    
    Due to our scientific training, technology development and design experience, and exposure to many industries, we are able to act as a “translator”, and convert R&D results and reports into Process and Instrumentation Diagrams, equipment specifications, line sizing, utility requirements, and plant layouts on which the project budgets and feasibility studies can be based.
    
    We are also able to identify gaps in the R&D data which indicate further research required to complete the picture.

  - Process Integration & Optimisation
    Process Integration & Optimisation
    Process Integration is generally understood to mean heat integration between different unit operations to provide the lowest energy configuration, epitomised by Pinch Technology techniques.
    
    However, a more holistic view is required when embedding new investment in an existing facility. Our experience, coupled with process simulation analysis, enable accurate performance rating of existing equipment. This in turn enables optimised integration of new equipment into an existing operation, thus optimising the client’s investment.

  - Project Management
    Project Management
    While Project Management is not Logichem’s core business, we have the multi-disciplinary resources and experience to offer competent execution of Project Management assignments.
    
    We are often requested by clients to undertake Project Management of projects which entail a substantial turnkey supply component by Logichem, and where the client does not have the engineering resources to handle the project management in-house. Such contracts often involve components like site bulk earthworks, civil design and construction, utilities and effluent treatment, etc., supplied by other engineering companies. These activities require co-ordination in terms of scheduling to minimize interruptions and optimize shared facilities such as site deliveries and crane usage. Overall progress and budget reporting would form part of Logichem’s services, as well as vendor invoice approvals where appropriate. Finally functional testing, commissioning, training, and hand-over documentation would be compiled, together with operating and maintenance manuals.

- Dealcoholization Technology
  Dealcoholization Technology
  Alcohol Reduction and Dealcoholization Technology for Fermented Beverages
  
  In response to the global trend to “lighter”, lower alcohol wines and beers, Logichem developed novel technology for alcohol reduction of fermented beverages with full retention of flavour. This process has been granted international patents and has been in commercial operation since 2014. It is licensed under the registered GoLo trademark.
  
  Why reduce alcohol?
  
  In the wine industry, the initial driver was the adjustment of alcohol content of high-alcohol wines to optimise its balance and taste. This was primarily applicable to the New World regions where excessive summer heat results in high alcohol levels. Subsequently, social, dietary, and health benefits have become increasingly important drivers for reduced-alcohol wines and beers and are expected to make it increasingly fashionable to drink low alcohol or alcohol-free versions of these drinks. For the producer and consumer there is also the benefit of lower excise tax depending on final alcohol content of the product.

- Ethanol Plants (Wine, Grain, Cane & Cassava Spirit)
  Ethanol Plants (Wine, Grain, Cane & Cassava Spirit)
  Ethanol production technology is our core business, from small 100 litres per day plants for the craft distilling industry, to 200,000+ litres per day industrial-scale distilleries.
  
  Logichem is the leading ethanol plant contractor in Southern Africa. In addition we have sold ethanol plants to clients in California, Australia, Ghana, and Israel.
  
  We provide complete turnkey solutions to clients in the cane (juice and molasses), maize (corn), wine, and cassava spirit industries.
  
  We can design for a range of products, spanning potable, industrial and cooking ethanol grades. Potable products range from flavoured varieties such as eau de vie, rum, and whisky, to neutral products such as vodka and extra neutral spirit.
  
  Our designs are based on comprehensive process simulation models of the various distillation processes to ensure optimum performance and efficiencies are achieved. Our models have been tried and tested and validated extensively on plant data from many operations over the past 20 years, and can be relied upon to produce accurate and trustworthy data and design parameters.
  
  Logichem developed proprietary high-efficiency, self-cleaning distillation trays that have been in service since 2002. Trays can be supplied in stainless steel, copper and titanium.
  
  Most of our equipment is manufactured in our own workshop, subjected to rigorous quality control and functional testing prior to dispatch.

- Craft Spirit Plants
  Craft Spirit Plants
  In addition to designing and building large industrial-scale distilleries, we also deliver small-scale plants for the Craft Spirit industry.
  
  Employing exactly the same design principles and techniques used in our industrial-scale plants, we offer bespoke, tailor-made designs to craft distillery clients to fit their exact requirements for producing unique products. We offer both batch processing pot stills, and continuous column stills fitted with our proprietary solid-tolerant trays. The latter allows distilling the solids-laden beer straight from your fermenter to produce a 96.4% neutral spirit in a single pass, a huge improvement in time and energy on the multiple pot distillation alternative. The same still is suitable for eau-de-vie, schnapps, vodka, whisky, and rum production.
  
  We also deliver mashing and fermentation equipment to suit various raw materials, starch as well as sugar based.
  
  We adjust the level of automation to suit the level of hand-crafted authenticity desired by the client.

- Clean Steam Generators
  Clean Steam Generators
  Normal boiler-generated steam is contaminated with corrosion protection chemicals dosed into the boiler feed water to conserve the boiler wetted components. It is therefore unsuitable for direct injection heating of food products. This has created a need for Clean Steam generators, particularly in the dairy industry.
  
  Clean steam generators are also used to harvest energy from geothermal steam which is often contaminated with high levels of sulphur compounds.
  
  Clean steam generators are essentially secondary boilers using “dirty” primary steam as heating source. They are constructed in corrosion-free alloys to suit the properties of the primary steam and therefore do not require corrosion protection chemical treatment on the secondary side.
  
  Logichem has supplied Clean Steam Generators for the dairy and ethanol industries utilising boiler steam as well as geothermal steam up to a capacity of 5 ton per hour at 10 bar pressure utilising 20 bar primary steam.
  
  We can custom design to fit the exact requirements pertaining to the application, including the high seismic structural specifications generally required for geothermally active regions.

- Logichem's Unique Water De-aeration Plants for the Brewing Industry
  Logichem's Unique Water De-aeration Plants for the Brewing Industry
  Logichem has developed novel technology for de-aeration of dilution water used in the beverage industries, typically in breweries.
  
  Logichem’s process is capable of reducing dissolved Oxygen (DO) to <10ppb, compared with typically 40ppb from conventional single-flash systems. Low DO extends product shelf life and is therefore highly sought after by beverage producers.
  
  Logichem’s process is based on multi-stage steam stripping in a trayed distillation column. The high efficiency of multi-stage contact reduces the steam requirement considerably, resulting in very low vapor-to-liquid ratio. This requires a good understanding of the hydraulic impact on tray design, resulting in highly unusual tray geometry to accommodate the high liquid load without flooding while still preventing weeping resulting from the low vapor load. Due to the instability of the protective oxide layer of stainless steel under these hot, low-oxygen conditions, trays are manufactured in Titanium.
  
  Unlike the CO2 stripping de-aeration processes, Logichem’s process is hot, resulting in sterilization of the water at the same time. Heat integration between feed and product streams results in high thermal efficiency and low energy cost.
