Reactor Function

Chemical reactions require controlled environment managing temperature, pressure, mixing, and residence time. Reactors provide containment, heat transfer for exothermic or endothermic reactions, agitation ensuring uniform conditions, and catalyst contact. Design optimizes conversion, selectivity, and yield meeting product specifications and economic targets.

Vessel Configuration

Vertical or horizontal pressure vessels with jacketed walls or internal coils for heating/cooling, agitator with motor and seal system, catalyst bed or slurry suspension, multiple feed points, temperature and pressure monitoring, sampling connections, and relief protection. ERGIL engineers reactors for specific chemistry, capacity, and operating requirements.

Heat Transfer Design

Jacketed vessels circulate heating/cooling medium controlling reaction temperature. Internal coils provide supplemental heat transfer. Proper surface area removes exothermic heat or supplies endothermic energy. Temperature control prevents runaways or incomplete reactions maintaining product quality and safety.

Agitation Systems

Mechanical agitators with turbine, paddle, or anchor impellers ensure uniform mixing. Motor sizing accounts for viscosity and power requirements. Seal systems prevent leakage of hazardous materials. Variable speed control adjusts mixing intensity. Static mixers suit plug-flow applications.

Material Selection

Stainless steel 304/316 resists corrosion from most chemicals. Hastelloy, Inconel, or titanium for severe corrosive service. Glass-lined steel for acids and pharmaceuticals. Internal cladding or PTFE lining alternatives. Materials per ASME Section VIII with corrosion allowances and temperature limits.

Applications

Petrochemical polymerization reactors, chemical synthesis vessels, pharmaceutical batch reactors, hydrogenation reactors, esterification vessels, alkylation reactors, and any process requiring controlled chemical reaction. Serves facilities from pilot scale to commercial production capacities.

Pressure and Temperature

Design conditions match reaction requirements from atmospheric to 200 bar, temperatures from cryogenic to 400°C. Proper materials and construction for extreme conditions. Relief systems sized for runaway reaction scenarios protecting personnel and equipment.

Control Systems

Temperature control manages heating/cooling maintaining setpoints. Pressure control regulates vent or feed rates. Agitation speed adjusts mixing intensity. Feed ratio controls optimize stoichiometry. Integration with DCS coordinates batch or continuous operation.

Safety Features

Relief valves protect against overpressure from runaway reactions or blocked outlets. Rupture discs provide secondary protection. Emergency cooling systems quench runaways. Gas detection monitors hazardous releases. Design per inherently safer principles minimizes risks.

Construction Standards

Design per ASME Section VIII with materials suitable for process chemistry. Agitator per AGMA standards. Relief sizing per API 520 accounting for reaction kinetics. Complete documentation with process hazard analysis and material certifications.
