A process improvement is a measure to enhance the performance of the plant. This can be just a simple change as, for example, optimisation of a procedure or a more complex substitution of equipment. The purpose is always either to cut power consumption or increase capacity, product quality, availability and/or safety. The process improvement needs to be defined, quantified and economically evaluated in order to make a decision about whether it should be realized. A process improvement can be the result of a performance investigation or a plant upgrade study or a client’s own investigation of plant performance. A principle path of execution can be summarized as follows.
- Evaluation of current status: customer provides past and present operating and analytical plant data relevant for the process, TKUCE engineer works out an evaluation
- Comparison with best practice
- Recommendations for improvements
- Technical and commercial proposal
- Engineering (P&I, specification, design, layout, etc.)
- Implementation of improvements, e.g. installation of a nanofiltration unit for sulfate removal, replacement of Cl2 drying unit with TKUCE Cl2 drying tower, improved filtration system etc.
- Delivery of hardware
- Installation at site
- Lower power consumption
- Higher product quality
- Greater availability
- Increased safety
