MEA-MDEA-NHD Desulfurization Technology
Brief description of the technology
A typical amine desulfurization and decarbonization process consists of four parts: absorption, flash evaporation, heat exchange and regeneration (stripping). Among them, absorption is the removal of the acid component from raw gas to a specified value or requirement; flash part is the removal of part of the hydrocarbons absorbed in the saturated liquid (i.e., the solution after the absorption of the acid component) when the acid component is absorbed by flash evaporation; heat exchange is the recovery of heat from the lean liquid leaving the regeneration column; Regeneration is the desorption of the acid component absorbed in the rich liquid to become a lean liquid for recycling. Raw gas through the inlet separator to remove free liquids and transfer solid impurities to the bottom of the absorption tower, and at the top of the tower, countercurrent contact of alcohol and amine solution flows from top to bottom, absorbing acid components. From the top of the column, a wet purge gas containing saturated water exits through an outlet separator to remove solution droplets carried out of the apparatus. Typically, this wet purge gas is dehydrated before being used as sales gas or sent via pipeline or downstream to an NGL recovery unit or LNG production unit.

Hydrogen production from coke oven gases
Coke oven gas has the characteristics of large gas volume, low pressure, complex impurity content and low hydrogen content. In addition to being used to generate electricity, hydrogen can be recovered for use in chemical plants such as coal tar hydrogenation plants, glycol plants and synthetic ammonia plants. High purity hydrogen gas is obtained from coke oven gas through compression, purification, conversion, PSA, etc. units. Through process integration, it is also possible to simultaneously produce CO, hydrogen and LNG products.
