Methacrylic Acid Manufacturing Plant Project Report 2026: Cost Analysis, ROI, and Feasibility Insights

The principal industrial route is the two-stage gas-phase catalytic oxidation of isobutylene. In the first stage, isobutylene is oxidized to methacrolein, which is subsequently oxidized to Methacrylic Acid using multicomponent molybdenum-based catalysts. Industrial processes typically operate within about 250–450 degree Celsius, while the direct oxidation route commonly uses air or oxygen as the oxidant. Alternative routes include oxidation of tert-butanol and the Acetone Cyanohydrin route.

Key feedstocks include isobutylene, isobutane, isobutyric acid, and acetone cyanohydrin, depending on the production route. For the conventional isobutylene oxidation route, isobutylene is the principal feedstock and raw materials account for approximately 60–70% of total operating expenditure, while utilities contribute about 8–12%.

Feedstock prices and availability are the main cost drivers, particularly isobutylene for the conventional oxidation route. Raw materials account for about 60–70% of total operating expenditure, while utilities represent approximately 8–12%; catalyst performance, conversion and yield, energy efficiency, purification requirements, maintenance, and plant operating efficiency also influence overall manufacturing costs.
