Catalysts drive the chemical reactions at the heart of petrochemical processing — from fluid catalytic cracking and steam cracking to polymerization and oxidation. Catalysts can be toxic, expensive, and sensitive to dosing accuracy. Precise injection ensures optimal reaction rates, product selectivity, and catalyst utilization while maintaining safe handling conditions.
Petrochemical plants process hydrocarbon feedstocks into the materials that define modern industry — polymers, solvents, detergents, adhesives, plastics, lubricants, intermediates, and specialty chemicals. These facilities are overwhelmingly process-driven: up to 95% of chemical dosing supports the core reaction, transformation, and treatment stages that convert raw feedstocks into high-value products.
This process intensity creates demanding dosing requirements. Catalysts, initiators, oxygen scavengers, corrosion inhibitors, emulsion breakers, and other difficult fluids must be injected with repeatable accuracy under high pressure, elevated temperature, and aggressive chemical conditions. Small deviations in feed rate can affect conversion efficiency, selectivity, product quality, equipment condition, and overall process safety.
Milton Roy offers metering pumps and packages that ensure accuracy in delivery of critical or difficult fluids. Our API 674 and API 675 compliant pumps have been designed for steady-state accuracy of ±1% and are available with multiple liquid-end configurations including critical service diaphragms to ensure peak performance. Through our global team of industry experts and channel partners, we design specialized solutions to meet your specific requirements.
Where Chemical Dosing Supports Petrochemical Operations
Toxic catalysts demand metering you can trust
Milton Roy has years of experience providing metering pump technology that withstands the harsh chemicals and conditions of catalyst reactor operations. Our hydraulically-actuated diaphragm pumps deliver ±1% steady-state accuracy with 100:1 turndown — ensuring safe, precise catalyst dosing every time.
Utilities Still Drive Petrochemical Uptime
Even in a facility where 95% of dosing supports the process, the remaining 5% dedicated to utilities is critical. Boiler feedwater, cooling water, demineralized water, and wastewater systems must all perform reliably to keep the process train running. A single utility failure can cascade into process instability, unplanned shutdowns, and costly production losses.
Milton Roy supports petrochemical utilities with the same precision and reliability that defines our process-side solutions — ensuring that every dosing point, whether in the reactor or the cooling tower, contributes to overall plant performance.
