Business Benefit Self-Cleaning Heat Exchanger

What is the benefit of a self-cleaning heat exchanger for an evaporator?After the first period of operation we can answer this question. The answer comes from the graph that is added to this post. Previous experience of the plant showed that because of fouling of the heat exchanger tubes, the evaporation capacity of the plant reduced with 50% within 12 days of operation. After the retrofit to our technology, using a fluidized bed with cleaning particles, the evaporation capacity remained constant.Before the conversion the average production capacity was only 75% of design. So, with our technology the client has gained 33% production capacity. The benefit would be even greater in case the production loss due to the down-time for cleaning (can take between 2 and 5 days) would be considered as well.When comparing the investment for adding 33% capacity using conventional technology with the investment for a retrofit into the self-cleaning heat exchanger, a decision can be easily made. The investment for a retrofit is a factor of 3 smaller.

Self-cleaning Evaporator Pilot Unit for the Concentration of Digestate

We have successfully operated our self-cleaning evaporator pilot unit for treating digestate from a biogas plant in Germany. The aim was reducing the volume of the Digestate without facing fouling problems and maintaining high heat transfer coefficients with this viscous fluid.

Next year the pilot unit will become available for other evaporation cases.

Order for 3 Evaporator Plants

Shachi Engineering Pvt. Ltd. (Pune), our partner in India, has been granted the order for 3 new waste water treatment plants for the dye-making industry. The plants apply multi-stage evaporation of which the first and second stage will be configured with the self-cleaning technology of Klaren International. The design of the plant has been optimized for steam efficiency and to have a compact design. The order was granted after a successful project in which one of the existing evaporators of this client was revamped into the self-cleaning system and showed constant evaporation where previously fouling was an important issue.
