Corrosion Control for Sugar, Pulp and Paper Mills
Corrosion monitoring, cathodic protection and off-crop preservation for sugar mills, ethanol plants and pulp and paper mills.
What drives complexity in this sector
Sugar mills and pulp and paper mills run some of the most corrosive processes in Thai industry: acidic cane juice and molasses, Kraft black liquor and bleaching chemicals, bagasse and biomass boilers that produce fly ash and sulphur oxides, and buried fuel, water and fire-water lines in wet ground. JST Group brings corrosion monitoring, cathodic protection, preservation chemistry and coating systems to mill operators across the cane belt and the paper-producing provinces, with programmes planned around the crop season.
Corrosive Process Gases
Sulphur compounds from Kraft pulping, bleaching chemicals and boiler flue gas corrode everything from structural steel to control-room electronics.
How we solve it: Corrosive Process GasesBoiler and Fuel Systems
Bagasse and biomass boilers, fly ash and piped fuel gas create corrosion on boiler circuits, ducting and the buried fuel and water lines that feed them.
How we solve it: Boiler and Fuel SystemsCorrosive and Abrasive Process Liquids
Cane juice, molasses, black liquor and bleach attack process piping, tanks and rotating equipment from the inside.
How we solve it: Corrosive and Abrasive Process LiquidsSeasonal Shutdowns
The off-crop season leaves idle equipment to corrode unless it is preserved, and compresses the window for survey and repair work into a few months.

Sugar, Pulp & Paper
Where corrosion starts in Sugar, Pulp & Paper assets, and how we stop it
The asset groups that corrode first, the mechanism behind each, and the JST service that addresses it. Compiled by our Corrosion Control Division from survey and maintenance work across the region.
- 01
Control, MCC and instrument rooms
How we solve it: Control, MCC and instrument roomsThe threat Hydrogen sulphide, mercaptans, sulphur oxides and chlorine from pulping, bleaching and bagasse boilers infiltrate control rooms and corrode circuit boards and contacts.
How we protect it Air IQ real-time atmospheric corrosion monitoring to ISA 71.04, filtration and pressurisation recommendations and vapour-phase inhibitor emitters in cabinets.
- 02
Boilers, flue-gas ducting and fly-ash areas
How we solve it: Boilers, flue-gas ducting and fly-ash areasThe threat Bagasse and biomass boilers produce fly ash, sulphur and nitrogen oxides that attack boiler tubes, ducting, structural steel and nearby equipment.
How we protect it Corrosion monitoring on the boiler feed-water and condensate circuits, coatings specified for flue-gas service and materials advice.
- 03
Juice, liquor and bleach piping
How we solve it: Juice, liquor and bleach pipingThe threat Acidic cane juice, molasses, Kraft black liquor and bleaching chemicals corrode and abrade process piping from the inside.
How we protect it Corrosion coupons, ER and LPR probes in process lines, materials selection and inhibitor programmes.
- 04
Buried fuel gas, water, steam and fire-water lines
How we solve it: Buried fuel gas, water, steam and fire-water linesThe threat Buried and exposed pipework carrying fuel gas, boiler feed-water, steam condensate and fire-water corrodes externally in the wet, acidic soils around a mill.
How we protect it Cathodic protection design and installation, DCVG and CIPS surveys and coating repair at soil-to-air transitions.
- 05
Fuel, molasses, black liquor and water tanks
How we solve it: Fuel, molasses, black liquor and water tanksThe threat Soil-side corrosion of tank floors and internal attack from water bottoms and corrosive product.
How we protect it Tank-bottom CP, CorroLogic vapour-phase inhibitor under the floor, internal linings and coupon monitoring.
- 06
Rolling equipment, bearings and off-crop lay-up
How we solve it: Rolling equipment, bearings and off-crop lay-upThe threat Mills, shredders, pumps and gearboxes corrode during the off-crop shutdown, and bearings fail early where lubricants carry acidic contamination.
How we protect it Cortec VpCI preservation of static and rotating equipment through the off-crop season, and corrosion-inhibited lubricants for roller bearings.
