Industrial Lining & Coating for Petrochem & Refineries — Sasol, Engen, Natref

Hemera Projects delivers engineered industrial lining and coating systems across South Africa’s petrochemical and refinery sector — Sasol Secunda and Sasolburg, Engen Durban refinery (Enref), Natref at Sasolburg, Astron Energy Saldanha, Total/TotalEnergies, Shell and the broader downstream petrochem industry. Storage tanks, process vessels, drums, reactors, pipework, structural steel and floor systems are all within scope, applied to the operator’s coating spec with documented application QC.

Petrochem and refinery coating projects live in a brutal corrosion environment — sulphur, hydrocarbon vapours, acidic condensate, salt, UV, elevated temperature and mechanical wear all attack unprotected steel and concrete. The right lining or coating system, properly applied, protects the asset for decades. The wrong system, or the right system poorly applied, fails inside months — and a coating failure inside a hydrocarbon storage tank, fuel pipeline or process drum costs more than the original coating budget many times over.

Hemera’s role on a petrochem coating project is to specify the correct system for the duty (or apply the operator’s specified system), prepare the substrate to the coating-spec standard, and apply the system with documented QC so the asset performs.

Where industrial coating is critical in a petrochem environment

Corrosion attack in a refinery or petrochem plant is constant and aggressive. Sulphur compounds in crude and intermediate streams degrade carbon steel; chloride salt-laden cooling water attacks heat exchanger and pipework internals; hydrocarbon vapours saturate atmospheric steel; acidic condensate in flue-gas paths corrodes ducting and stack; UV breaks down organic coatings on external surfaces. Without engineered coating systems specified for each duty, asset replacement cost outpaces the maintenance budget within years.

Hemera’s coating crews work across the full range of petrochem coating scopes:

• Crude, product and intermediate storage tanks: Internal linings (epoxy, novolac, vinyl ester, polyurea) and external coating systems (epoxy/polyurethane) for crude oil, refined product, intermediate, additive, and slop tanks. Floor zone, shell wall and roof linings each engineered for the storage service.
• Process drums, reactors and vessels: Internal linings for separator drums, knock-out drums, charge drums, FCC reactors, hydrocracker reactors and process vessels exposed to specific chemistries.
• Heat exchanger water-side coatings: Where saline cooling water or process water service warrants a barrier coating on the water-side surfaces of heat exchanger shells and channel covers.
• Pipework coating and lining: Internal lining and external coating of refinery process pipework, fuel oil pipework, steam pipework, instrument air and utility lines.
• Structural steel coatings: Pipe rack columns, vessel skirts, deck steel, walkway and stair structures — all exposed to aggressive atmospheric corrosion in a petrochem operating environment.
• Bund and tank-pad coatings: Chemical-resistant floor systems for tank farms, bunded areas, drum-storage zones and process spill containment.
• Stack, duct and gas-handling system coatings: Internal coatings for flue-gas ducting, FGD equipment, scrubber internals and stack interiors.

Hemera Projects: Coating Specialists for SA Petrochem and Refineries

Our reputation in this sector is built on three things: the right system for the duty, properly prepared substrate, and documented application QC. Each scope is mobilised with the equipment, applicators and supervisors needed to deliver the spec — every layer thickness recorded, every coat inspected, every test pulled and signed. The result is a coating that performs and a project record the operator can audit, hand to the certifier and use to plan the next maintenance cycle.

Coating Applications Specific to SA Refineries

South African refineries and petrochem complexes share common coating requirements with international peers but have specific local variants — coastal refining at Saldanha and Durban brings salt-laden atmosphere; inland operations at Sasol Secunda and Sasolburg bring acidic condensate and CO/CO2 atmospheres; gas-to-liquids and coal-to-liquids operations bring unusual process streams that mainstream refineries don’t see. Hemera’s coating capability covers each variant with engineered systems matched to the duty.

Specific coating scopes that recur in our SA petrochem work include:

• Crude tank floor and shell linings — epoxy or novolac systems for crude oil storage with rust-prevention and demulsification properties
• Refined product tank linings — clean-service epoxy systems for fuel storage
• FCC reactor and regenerator refractory anchor coatings
• Sulphur recovery unit coating systems
• Cooling water heat exchanger water-box and channel coatings
• Effluent treatment plant coating systems
• Stack and gas-handling coatings
• Bunded tank-farm floor systems

Painting and coating applications are critical in protecting these refinery assets, forming a robust corrosion protection envelope around the steel or concrete substrate. The application sequence — surface preparation, primer, intermediate, topcoat — is engineered for the specific service, with each coat applied at the right film thickness on a clean, profiled substrate. The role of the applicator on a refinery turnaround is to deliver this without compromise even when the work window is tight, weather is unfavourable, and the working environment is challenging.

Hemera’s coating crews are trained, certified and equipped for petrochem-specific work. Our equipment includes airless spray pumps, rotary atomisers, plural-component pumps for fast-cure systems, and the auxiliary kit (containment, heaters, dehumidifiers, blast pots) needed to control conditions at the work face. Our supervisors enforce the application spec on every shift, and our QC documentation is project-grade for major operators.

Operators we serve in SA petrochem and refining: Sasol Secunda, Sasol Sasolburg, Natref Sasolburg, Engen Durban Refinery (Enref), Astron Energy Saldanha, Total/TotalEnergies, Shell, BP and the broader downstream distribution and blending sector.

While corrosion protection and coating remain Hemera’s core expertise on petrochem sites, our SA operation supplies a full industrial services catalogue around the coating scope — surface preparation, insulation, fireproofing, scaffolding and access — combined into a single contractor scope. See related Hemera services for the full picture: HP & UHP water jetting for petrochem and refineries for surface preparation, insulation, lagging and cladding, industrial fireproofing for petrochem and fuel storage, thermal metal spray, and scaffolding for petrochem turnarounds. Single contractor, single safety plan, single supervisor, single accountable interface to the operator.
