HJM’s TDM (Technical Design Model)

HJM's Technical Design Model (TDM) is a detailed design package simulator which synthesizes optimized chemical routes for a range of chemical products. From choice of raw material, to reactor design, seperation units and even heat exchangers network, TechP does it all.

Any start-up business in the chemical industry requires an assesment of the production. This includes the choice of raw materials, production process, and product derivative produced. The assesment includes:

• Availability of raw material
• Raw material import possibility from neighbouring market
• Tax regims and legislation of imports
• Market share for the product produced
• Product export from competitive markets

Once the model optimizes between various possibilities, the design continues to produce a comparative analysis of the finanacial investment and return for each route:

1. Estimation of Capital Costs
2. Estimation of Manufacturing Costs
   
3. Engineering Economic Analysis
4. Profitability Analysis

The economic capital cost assesment includes:

• Detailed estimate 
• Definitive estimate 
• Preliminary estimate 
• Study estimate 
• Order-of-magnitude estimate 

The TDM profitibality analysis includes:

• Evaluate the profitability of chemical processes 
• Profitability criteria using nondiscounted and discounted bases 
• Net present value (NPV), discounted cash flow rate of return (DCFROR), and payback period (PBP) 
• Evaluating equipment alternatives using equivalent annual operating costs (EAOC) 
• The concept of evaluating risk

Other considerations of the model includes:

• Land size
• Population demographics
• Enviromental restrictions
• And more ...
  

The model finally generates the best route for the chemical produced.
