Experts, can gas containing 0.04% hydrogen sulfide be directly discharged into an overhead flare together with flare gas containing styrene, butadiene, and other substances?

Dear experts, I have a question: Can crude gas containing 0.04% hydrogen sulfide be combined with substances such as styrene, ethylbenzene, and butadiene in the same pipeline and then sent to an overhead flare? Thank you all, please give your reasons.
Yes, there are no issues with combustion; moreover, since it is an elevated torch, it meets the requirements of relevant standards and specifications. The only concern is corrosion of the pipes; based on experience, ordinary carbon steel can handle this level of hydrogen sulfide, so no additional anti-hydrogen sulfide treatment is necessary
Other components need to be considered, such as the water content in hydrogen sulfide gas and the emission temperature. If the temperature and humidity are within normal limits, it is acceptable; anti-corrosion and crystallization measures should be taken into account
To provide recommendations, data calculations are required, as well as your factory’s safety and environmental CEMS control parameters. Without quantitative data and relevant indicators, who can give you an accurate answer?
