Dear sea friends, does anyone have any information on the methionine production process? Thank you

Producing methionine by reacting hydrogen sulfide with methanol to yield methyl mercaptan can reduce costs and shorten the production process. The main reactions are as follows: CH30H + H2S → CH3SH + H2O; CH3SH + CH2CHCHO → CH3SCH2CH2CHO; CH3SCH2CH2CHO + HCN → CH3SCH2CH2CHOHCN; CH3SCH2CH2CHOHCN + NH3 → CH3SCH2CH2CH(NH2)CH3; CH3SCH2CH2CH(NH2)CN + HCl → CH3SCH2CH2CH(NH2)COOH (methionine)
