The present invention relates to a process for removing acid compounds contained in a gaseous effluent which consists in bringing a gaseous effluent into contact, in the absorption column, with an absorbent solution comprising water, between 20% and 28% by weight of pentamethyldipropylenetriamine and between 5% and 35% by weight of N-methyldiethanolamine.

Method for removing acid compounds from a gaseous effluent using a tertiary amine-based absorbent solution

The present invention is a sensor for measuring a risk of hydrogen embrittlement of industrial equipment including a metallic wall in a reactor or in a pipeline comprising a body having a closed cavity including an end containing a pressure sensor which measures pressure within the closed cavity, the metallic wall having a wall thickness measured between inner and outer surfaces thereof, and wherein a ratio of thickness of the metallic wall to thickness of the industrial equipment ranges from 1/3 to 1/10.

Sensor for measuring the embrittlement of steels by hydrogen in an aggressive environment, said sensor comprising a metal cavity connected to a pressure-measuring device

The gaseous effluent is contacted with an aqueous solution comprising at least one amine and at least one amine degradation inhibiting compound. A stainless steel withstanding corrosion upon contact with the amine degradation inhibiting compound is first selected. Equipments whose surfaces in contact with the aqueous solution are made from this stainless steel are used.
