Maleic Acid Hydrogenation Reactor

Maleic acid, also known as cis-butenedioic acid, is primarily used in the production of unsaturated polyester resins and in the synthesis of compounds such as tartaric acid, fumaric acid, succinic acid, DL‑malic acid, dye auxiliaries, and fat and oil preservatives. It also finds relatively broad applications in the pharmaceutical, agrochemical, and food industries. This unit is a two‑gas‑one‑liquid fixed‑bed reactor system designed and manufactured according to PID process specifications. YanZheng Instruments can customize complete reaction systems tailored to customers’ specific process requirements.

Product Description

Maleic acid, also known as cis-butenedioic acid, is primarily used in the production of unsaturated polyester resins and in the synthesis of compounds such as tartaric acid, fumaric acid, succinic acid, DL‑malic acid, dye auxiliaries, and fat and oil preservatives. It also finds relatively broad applications in the pharmaceutical, agrochemical, and food industries. This unit is a two‑gas‑one‑liquid fixed‑bed reactor system designed and manufactured according to PID process specifications. Yan Zheng Instruments can customize complete reaction systems tailored to customers’ specific process requirements.

Introduction to the Plant Process

The main process flow of the maleic acid hydrogenation reactor system involves controlling the inlet gas flow via a mass flow meter. Maleic acid is drawn from the raw material tank by a PEEK pump and fed into the system as a concentrated solution. The liquid and gas are separated and then enter the reactor, where they are preheated, vaporized, and thoroughly mixed in the bed. After being fully preheated and vaporized, the temperature rises to the reaction temperature, after which the feedstock flows through the catalyst bed. The effluent is then mixed with bypass hot water before entering the cooling module, where the temperature is reduced to the customer‑specified target temperature. Finally, the product enters the gas–liquid separation tank: the liquid phase remains in the separation tank and is discharged periodically, while the gas phase passes through a pressure controller and is routed to the tail gas emission system. This electrical control system comprises both electrical hardware—including electrical components and control cabinets—and instrumentation (such as pressure transmitters, MFCs, and temperature sensors). It is equipped with an automatic ramp‑up program, which can be configured in the secondary instruments.
