Integration of hydrogen-rich fuel gas production with olefins production facilities
By integrating H2-rich fuel gas production and olefin production facilities, and employing syngas production, waste heat recovery, and multi-stage conversion reactions, high-concentration H2 fuel gas is produced for olefin production. This solves the problem of high CO2 emissions caused by fuel gas combustion and achieves a dual improvement in cost and efficiency.

AI Technical Summary
Technical Problem
In existing olefin production facilities, the combustion of fuel gas results in a large amount of CO2 emissions. Traditional CO2 capture technologies are costly and complex, making it difficult to efficiently reduce CO2 emissions.
Method used
By integrating H2-rich fuel gas production facilities with olefin production facilities, high-concentration H2 fuel gas is produced for olefin production through syngas production, waste heat recovery, multi-stage conversion reaction and CO2 recovery, thereby reducing combustion demand and lowering CO2 emissions.
Benefits of technology
It has achieved significant reductions in CO2 emissions, lower capital and operating costs, improved energy efficiency, and simplified equipment layout.

Abstract
H2-rich fuel gas production facilities comprising a syngas production plant can be advantageously integrated with an olefins production facility comprising a steam cracker in at least one of the following: (i) fuel gas supply and consumption; (ii) feed supply and consumption; and (iii) steam supply and consumption, resulting in substantial savings in capital and operating costs, enhanced energy efficiency and reduced CO2 emissions compared to running the facilities separately.
