Oil & Gas Chemical Injection

In upstream operations, chemical injection supports flow assurance, asset protection, and production optimization. Whether onshore or offshore, operators need reliable dosing of methanol to prevent hydrate formation, corrosion inhibitors to protect wellbore and production tubing, scale inhibitors to prevent mineral deposits, and demulsifiers to support oil-water separation.

Milton Roy metering pumps and customized packages deliver these chemicals with the precision, reliability, and hazardous-area compliance that production environments demand. Our solutions are proven across conventional production platforms, subsea tiebacks, FPSO vessels, and FLNG operations.

Key upstream dosing applications

• Methanol and MEG injection for hydrate prevention
• Corrosion inhibitor injection for production tubing and flowlines
• Scale inhibitor dosing for downhole and topside protection
• Demulsifier and emulsion breaker injection
• Wax and asphaltene inhibitor dosing
• H₂S scavenger injection for sour service environments
• Biocide dosing for reservoir souring control

During transportation through pipelines, FPSO offloading, or terminal storage, crude oil and natural gas remain exposed to corrosion, fouling, and quality degradation risks. Midstream chemical injection helps maintain product integrity, protect infrastructure, and support safe handling from production to processing.

Milton Roy mixing products also provide reliable agitation of crude product during transportation and storage, preventing sedimentation and ensuring product homogeneity before downstream processing.

Key midstream dosing applications

• Corrosion inhibitor dosing for pipeline systems
• Drag reducing agent (DRA) injection
• Biocide dosing for pipeline microbiological control
• Crude oil mixing and homogenization in storage tanks
• Chemical injection on FPSO and FLNG vessels

Downstream operations are among the most dosing-intensive environments in the energy sector. In refineries, chemical injection supports crude separation, distillation, product treatment, blending, corrosion control, and wastewater management. A typical refinery operates over 200 metering pumps across its process and utility systems.

In petrochemical plants, precise injection of catalysts, initiators, inhibitors, and difficult fluids directly influences reaction quality, product consistency, and process safety. Milton Roy's API-compliant metering pumps and engineered packages are purpose-built for these critical downstream applications.

Water is the largest by-product of oil and gas production. Produced water extracted during hydrocarbon separation must be treated before reinjection, disposal, or reuse. This requires precise dosing of sodium hypochlorite, biocides, scale inhibitors, oxygen scavengers, coagulants, and pH adjustment chemicals.

When standard pump selection is not enough, Milton Roy designs and manufactures complete chemical injection packages — from compact skid-mounted systems to fully engineered, project-specific solutions for offshore platforms, FPSO/FLNG vessels, onshore processing plants, and terminal operations.
