LNG in Spotlight

Vahterus’ LNG journey began in 2005. Through extensive R&D work and with over 300 heat exchangers delivered to cryogenic LNG applications, we’re now leaders in the field. In this special issue, we introduce our work in LNG applications.

EDITORIAL

Development Continues Despite Difficult Times

None of us could have guessed how radically the world would have changed since we published the last issue of our magazine. Most countries are in lockdown and all public gatherings and events are banned. Travel is restricted by special legislation. And all of this because of a sudden and tragic virus pandemic that changed the way we live and work in the space of just a few weeks.

Luckily, in the heat-transfer business, investments continue to be made. Our customers are always striving for ways to make energy savings and to find circular solutions, and it’s our ambition to remain in partnership with you, our valued clients, in researching this development work. Together, we can improve our processes and discover sustainable solutions to tackle climate change and ensure a safe environment for the next generations. We thank you for your continued inquiries and orders. What’s most positive is that our factories are operating at full capacity and there are no signs of the coronavirus in any of our companies globally.

LNG opens doors

In this edition of Hot & Cold, we focus on heat-exchanger solutions in LNG applications. Our customers are changing energy source from heavy fuel oil to Liquefied Natural Gas (LNG), which is becoming an increasingly popular fuel in marine and onshore applications and in power generation.

The rich possibilities offered by LNG have encouraged us to undertake extensive R&D work to understand the special features of heat transfer with cryogenic fluids. For an engineer, it’s always exciting to see the extremes, for example in temperatures, like using liquid nitrogen at temperatures of -180°C to test our heat exchangers in an environment that’s equal to LNG vaporising conditions. That’s pretty cold!

In these conditions, the materials, the welding quality, as well as heat-transfer efficiency of our exchangers are rigorously tested. That has been our focus this spring. On the following pages, you can read about a larger series of cryogenic experiments in our Test Lab and about FEM simulations that help us to continuously improve the constructions used in the cryogenic environment. We’ve also successfully refined our processes. The development research is done together with you, our customers, and the work continues. I believe that the use of LNG will increase significantly over the next decades, especially with large engines. We at Vahterus are making it our business to be part of this development work in the future.

Reasons to celebrate

Vahterus was founded on 5 September 1990 and we’re approaching our 30th anniversary. Unfortunately, in the circumstances it looks as if we’ll have to postpone our celebrations of this landmark event with you. It also seems we won’t be gathering at exhibitions this autumn, because most events have been cancelled.

However, we look forward to getting together with you when the pandemic passes. In the meantime, we’ll do our best to stay in touch on other platforms digitally.

I wish you health and continued success in your business!

Together we succeed!
