AIChE Spring Meeting in Houston, TX

Hexxcell will present a paper at the next American Institution of Chemical Engineers (AIChE) to be held in Houston, TX on April 10-14, 2016.

The AIChE Spring Meeting is the year’s key technical conference for practicing chemical engineers and covers a variety of topics.

Hexxcell will present a paper titled "Cleaning Heat Exchangers: How, When, Where and How Much?" discussing the advantages and disadvantages between chemical and mechanical cleaning methods. Moreover, the presentation will include:

  1. Establishing the effectiveness and depth of cleaning achieved by different chemical cleaning agents and the exchanger conditions left at the end (which depend on the deposit state prior to the cleaning and cleaning time). These will also affect fouling build-up in subsequent operation.

  2. Minimising the cleaning time for a specific chemical cleaning agent (which we term “condition-based cleaning”)

  3. Calculating the detailed interaction effects that cleaning individual exchangers has on the fouling, heat duty and pressure drop of other exchangers in a network and overall

  4. Generating alternative cleaning schedules involving the selection of the appropriate type of chemical and mechanical cleaning, and assessing the cleaning schedule performance based on thermal and hydraulic considerations, costs of energy and refinery margins.
