Heat Exchanger

Heat exchangers are very important components in many industrial applications, as they enable the efficient transfer of heat between different mediums. IBL has specialized in particular in the analysis and optimization of the strength properties of shell and tube heat exchangers. The classic shell and tube heat exchanger generally consists of a central tube bundle surrounded by an outer shell. However, IBL also has sufficient references for the analysis of shell-and-tube heat exchangers with a central tube or with several concentrically arranged tube bundles.

In addition to the dimensioning of pressurized parts according to international standards, regulations (e.g. ANSI B31.1, ANSI B31.3, EN1380), rules (KTA, FDBR guidelines, etc.) and manufacturer-specific specifications (Users Design Specification, material data reports, etc.), our expertise lies in particular in the evaluation and improvement of the strength of tube plate constructions and vessel flange connections used in heat exchangers. We understand that the correct design of these components is critical to ensure that they can withstand operational requirements and ensure long-term reliability.

To do this, we use advanced, internationally recognized analysis methods and simulation techniques to understand the loads and stresses on the tube plates. Through detailed linear-elastic and elasto-plastic strength analysis, we identify potential weak points and develop tailor-made solutions to extend the service life of the heat exchangers and optimize their performance. We have developed our own evaluation tools to assess the fatigue/residual service life, with which we can identify the exact number of (still) permissible load cycles for each point of a tube plate design and thus estimate quite accurately which measures you can use to effectively increase the (residual) service life.
We attach great importance to precision, efficiency and innovation in our work. Our customers benefit from our many years of experience and our commitment to excellence in the strength analysis of heat exchangers.

Synthesis gas is a mixture of different gases that is often produced in chemical processes, especially in the production of hydrocarbons from coal, biomass or natural gas. In many industrial processes, the temperature of the synthesis gas must be lowered to bring it to a state suitable for subsequent processing steps…

Over the past quarter century, IBL has analyzed and dimensioned both the vessel shells, the supporting elements and the internals, especially the heating surfaces and their load transfer of various types of synthesis gas coolers for mechanical and thermal loads according to ASME VIII/1, ASME VIII/2, EN13445-3, PD5500 or AD2000 for various customers. In part, the IBL staff determined the wind and earthquake loads according to ASCE, UBC, SBC, Eurocode, Chinese Code, Australian Standard and with flexibility calculations according to ANSI B31.1, ANSI B31.3 or EN13480-3 the pipe connection loads and developed corresponding load transfer concepts.
