Conduct Feasibility Study

When your are dealing with (severe) fouling of heat exchangers in your process(es) and you want to know if the self-cleaning heat exchanger technology can solve the fouling, we can evaluate the potential of the technology for your specific application(s).
Detect Potential Applications and Processes Identify fouling issues in heat exchangers, perform an analysis to evaluate whether the technology can solve the fouling problems sufficiently and prioritize the issues based on the potential.
Make Process Concept Design Assess the impact of the integration of the self-cleaning heat exchanger technology in the current process and defined focus area(s), determine the required modifications and make a preliminary process and heat exchanger design that shows the integration of the self-cleaning heat exchanger within the process.
Conduct Technical Evaluation Assess the technical feasibility of the conceptual process design against the current set-up (such as footprint and utilities).
Make Business case Capture in a Business Case both the quantifiable and non-quantifiable benefits of the implementation of the self-cleaning heat exchanger technology.
 

Design self-cleaning heat exchangers

Every client case with fouling is unique in terms of process conditions and composition of the media applied. The configuration of a self-cleaning fluidized bed heat exchanger needs to be tuned in order to achieve operation up to zero-fouling. We work according to a five step approach:
Input Client Case Collect all required process conditions, such as flow, temperature, cooling or heating medium.
Basic Sizing of Full Scale Unit Based on the process conditions the basic layout and dimensions of a Full Scale Unit can be calculated and designed (tube diameter and length and the number of tubes).
Test at Client Site A test is required to determine the overall heat transfer coefficient and to demonstrate the self-cleaning performance. The test will be performed at the client site and at client conditions taking into account the tube diameter and length of a full scale unit and a flow in 1 tube at ΔT and ΔTlog. During this test particle size, bed porosity and flow are optimized. For this test our proprietary single tube test unit is used.
Design Full Scale Unit Output is a full scale self-cleaning heat exchanger design with optimized fluidized bed parameters.
Project Realization The detailed engineering, manufacturing, erection and commissioning of the self-cleaning heat exchanger.
 

Revamp heat exchangers

The self-cleaning heat exchanger technology offers the possibility of revamping existing vertical conventional severely fouling heat exchangers into a self-cleaning configuration. These possibilities are particularly interesting for severely fouling reboilers, evaporators and crystallizers. In general, the requirements for the majority of revamps can be summarized as follows:
  • The same process conditions should be maintained;
  • The connections to the column or flash vessel should be maintained;
  • The installed pumps should be used;
  • The existing channels should be re-used where possible;
  • The revamp must be carried out within the available space.
Input Client Case Collect all required process conditions (i.e. flow, temperatures and cooling/heating medium) and layout and dimensions of the current heat exchanger (i.e. tube diameter and length, number of tubes and heat exchanger location and orientation).
Revamping potential assessment Conduct an assessment (i.e. layout and dimensions) to evaluate the possibility to convert the current heat exchanger into a self-cleaning configuration.
Test at Client Site A test is required to determine the overall heat transfer coefficient and to demonstrate the zero-fouling performance. The test will be performed at the client site and at client conditions taken into account the tube diameter and length of the full scale unit (current heat exchanger) and a flow in 1 tube at ΔT and ΔTlog. During this test particle size, bed porosity and flow are optimized. For this test our proprietary single tube test unit is used.
Design Full-Scale Unit Output is a design of the required modifications to convert the current heat exchanger into a self-cleaning heat exchanger with optimized fluidized bed parameters.
Project realization The detailed engineering, manufacturing, erection and commissioning of the self-cleaning heat exchanger.
