LanzaTech provides mobile gas testing services as part of our project development process. The Gas Testing Station (GTS) is capable of testing the compatibility of the gas streams from your industrial process with our gas fermentation process. If you are interested in testing your gas stream or have any questions, please feel free to contact us at firstname.lastname@example.org
Over the last couple of years, LanzaTech has run demonstration plant facilities in New Zealand, China and Taiwan, learning from over 40,000 hours of testing how the gas fermentation process runs with steel mill waste gasses. To test the compatibility of the LanzaTech gas fermentation process with the steel mill waste gas at ArcelorMittal’s site in Ghent, Belgium, a mobile fermentation unit (Gas Testing Station) was installed for a number of weeks.
The boilerroom houses two blast furnace (BF) burners, an ideal place to tap off some steelmill gas, direct this to the mobile unit and perform the compatibility tests. The microbes utilize the carbon monoxide in the gas, start growing and produce ethanol.
The gas fermentation unit has been connected to blast furnace gas without any pre-treatment of the gas. Exposing the LanzaTech microbe to the non-pre-treated blast furnace gas provided insight into the effects of methane, oxygen and other low level contaminants present on the fermentation performance.
Two runs using untreated blastfurnace gas demonstrated significant microbial growth and ethanol production. This was a promising result for the first live test and an important step for the project showing the integration of the LanzaTech process within ArcelorMittal’s steel mill in Ghent.
What is a Gas Testing Station?
The Gas Testing station (GTS) is a portable self-contained, gas fermentation apparatus. It is designed as a tool testing LanzaTech gas fermentation technology compatibility with raw process gas and local water and potentially locally sourced industrial chemicals at any location in the world.
The GTS is capable of performing fermentation of carbon monoxide (CO), carbon dioxide (CO2) and hydrogen (H2) containing gases into ethanol and other liquid products. Two gas lift reactors are installed, precise gas flow control, dosing pumps, a safety system and the required analytics (gas chromatograph, GC) to monitor the gas composition and liquid product profile.
