Quantitative safety assessment for reactor size variation on high pressure methanol production / Mohd Aizad Ahmad, Anis Adila Rozman and Zulkifli Abdul Rashid

This work studied carbon capture utilization (CCU) to methanol synthesis, which analyses reactor size's impact on high-pressure methanol production. As high pressure poses a high probability of process vessel leakage, assessment on its potential hazardous chemical impact such as toxicity, fire,...
