Projects
The list on the right contains projects, which give a good impression of our work: adapting existing plants. In all cases we did the preliminary study and the conceptual design of the measures required.Our further involvement varies per project. In many cases, also a technical requisition for quotations was prepared and an evaluation of the bids of suppliers conducted. In fewer cases, in addition the detailed engineering of the supplier was guided and support during commissioning provided.
Further details can be explained case by case after consultation with the customer concerned.
- Smart cooling tower makes chilled water unit unnecessary and thus makes project feasible.
- Choice for absorption cooling for a minus 60 Celsius unit restores steam balance and prevents the cost of blowing off steam.
- Fuel gas with variable composition safely fired with 10% excess air, thus preventing excessive stack losses.
- Revamp of high pressure steam boilers to Low NOx extends the life with at least ten years.
- Optimizing of an incinerator increases the capacity by 25%.
- Unstable 200.000 m³/h air flow measurement becomes stable and less expensive by flow modeling.
- Stains on lime sand bricks for 'in sight' work avoided by adaptation of the steam system.
- Malfunctioning of economizer solved by modeling flow.
- Model of large silica air drying unit predicts behavior during extreme summer heat.
- Utilization of residual gas from silicon carbide manufacture saves 30% on electricity bill.
- Conversion of turbocompressor from steam turbine drive to elecric motor pays back in 2 years.
- Conceptual and basic engineering of turbocompressors for plant air is the basis for 80 t/h plant air facility.
- Improvement of surge control system of turbocompressors saves 500 kW of electricity.
- Heat transfer at at high temperature and high pressure in ammonia synthesis successfully implemented after too many leaks in the original design.
- Issues of quench coolers in naphta crackers and heat exchangers in nitric acid plants: a compromise between just thick enough to withstand pressure and elasic enough to handle thermal stress.
