Safe, on-spec gas with lower operating costs.
Sour gas containing hydrogen sulfide (H₂S), carbon dioxide (CO₂) and mercaptans is a major challenge for Iraq’s growing gas sector. It corrodes pipelines, poisons downstream processes, creates serious safety risks and prevents gas from meeting sales and power-plant specifications.
Expert Chem SERV provides a complete range of gas sweetening chemicals and technical services for gas processing plants, oilfield facilities, refineries and power stations. We help operators remove acid gases efficiently, protect assets and reduce operating costs.
Amine Sweetening Solvents
For continuous H₂S and CO₂ removal in amine treating units:
- MDEA (Methyldiethanolamine): selective H₂S removal with low regeneration energy
- Activated MDEA blends: faster CO₂ removal for deep acid-gas treatment
- DEA (Diethanolamine) and MEA (Monoethanolamine) for combined H₂S and CO₂ removal
- DGA (Diglycolamine) for high acid-gas loadings
- Formulated specialty solvents, tailored to your gas composition, treating targets and plant design
H₂S Scavengers
For wellheads, pipelines, storage tanks and facilities without an amine unit:
- Triazine-based liquid scavengers for fast, economical H₂S removal
- Non-triazine scavengers to reduce scaling risk and suit sensitive systems
- Oil-soluble scavengers for crude oil and condensate
- Solid bed scavengers (iron oxide based) for low-flow gas streams
Amine Unit Performance Chemicals
Keep your amine unit running smoothly and efficiently:
- Antifoams, both silicone and non-silicone, to stop foaming, carryover and solvent losses
- Corrosion inhibitors for amine systems, reboilers and regenerator overheads
- Jacobi activated carbon for amine filtration to remove hydrocarbons and degradation products
- Heat-stable salt management products and solutions
Gas Dehydration
Often the step that follows sweetening:
- TEG (Triethylene Glycol) for gas dehydration units
- MEG (Monoethylene Glycol) and methanol for hydrate prevention
- Glycol antifoams and pH control additives
Technical Services
Chemicals alone don’t guarantee performance, so we support your unit throughout its operation:
- Amine solution analysis: amine strength, rich and lean loading, heat-stable salts, degradation products and contaminants
- Amine unit health checks and audits to find losses, foaming, corrosion and energy waste
- Troubleshooting of foaming, off-spec gas, high amine losses and corrosion problems
- Solvent selection and changeover support when switching to a more efficient amine
- H₂S scavenger program design: product selection, dosing optimization and field trials
- Dosing equipment: chemical injection pumps and skids
- Monitoring: HACH laboratory and online analyzers
- Operator training on amine unit operation, sampling and testing
