“…In addition, severe corrosion often occurs in the phase change region of the regeneration tower. The simulated corrosion environment of carbon steel in MDEA solution mainly involves the liquid phase [19][20][21]. The corrosion behaviour and corrosion mechanism of carbon steel in gas phase environments were seldom explored.…”

The effects of HSS (heat-stable salts) on the corrosion behaviours of 20 steel were explored using selfdesigned HTHP autoclave. The charateristics of corrosion scales were investigated by SEM, EDS and XRD. Corrosion scales of 20 steel formed in the liquid phase environment were mainly composed of FeS 2 , Fe 3 O 4 , and Fe. HSSs affected the corrosion rate through changing the morphology of corrosion scales of 20 steel. Inorganic salts enhanced the attractive force between ions and the hydrolysis of CH 3 COO − in organic salts promoted the ionisation of HS − , which accelerated the deposition of FeS on the surface of 20 steel to form a dense corrosion scales, thereby significantly reducing the corrosion rate of 20 steel. Inorganic-organic salts reduced the bonding opportunity between Fe 2+ and S 2− and allowed the formation of porous corrosion scales on the surface of 20 steel, thus increasing the corrosion rate of 20 steel.

“…However, the chemical absorption methods (such as the MDEA method) have limited desulfurization and decarbonization efficiency due to limitations posed by pressure conditions . Besides, they require intensive energy expenditure majorly in the solvent regeneration process. , Abedini et al investigated the acid gas removal performance using an amine solvent with wet gas conditions of 220 and 750 psia. It was found that when MDEA was used to purify sour gas containing large amounts of CO 2 under low pressure, the product gas became unable to reach the requirements of the sales gas specification and the additives of other amine components could improve the plant performance.…”

Given the drawbacks of the traditional MDEA absorption process, we introduced a hydrate-based gas separation approach. Then, to study the effectiveness of this method, we performed some hydrating experiments demonstrating that energy consumption could be remarkably reduced. However, the acid components (H 2 S and CO 2 ) in the product gas failed to meet the specification requirements of the sales gas. Consequently, a new technique was developed that integrated hydrate-based gas separation and chemical absorption for the sweetening of natural gas with high H 2 S and CO 2 contents. To evaluate the performance of this new integrated method, technical comparisons based on simulation and experimental data were conducted. The results showed that the new integrated method could effectively remove sour components, which resulted in the product gas being able to meet the sales gas specifications. Additionally, the integrated technique consumed much less energy than the traditional MDEA absorption process and its amine regeneration duty was only 42% that of the MDEA method. What is more, upon an economical evaluation being performed, it was shown that the integrated technique tremendously reduced the investment and operating cost.
