Application requirements
Traditionally, THT is added pulse-wise to the gas on a regular basis, using a pump with a fixed stroke volume. Especially for small gas flow - for biogas installations in the range of 40-50 m3/hour - such a batch-wise injection may lead to liquid THT remaining in the gas lines. In this way, THT may not be mixed well with the gas, it might have the wrong concentration and there is no control on supplying. These lacks of guarantee for continuity and accuracy have to be overcome with the new solution.
