Challenges in the Palm Oil Industry

The palm oil industry is one of the strategic sectors in Indonesia that supports national economic growth. However, in the production process, there are various critical equipment that have the potential to experience technical and chemical disruptions. If not handled properly, these disruptions can lead to decreased productivity, equipment damage, and environmental pollution.

The following is a comprehensive description of various critical equipment in the palm oil industry, common problems that often occur, as well as solutions and products that can be used to overcome them.

1. List of Problems in the Palm Oil Industry

2. Explanation of Palm Oil Industry Issues

2.1. Boilers

Boilers are the heart of the thermal process in palm oil mills. Its function is to generate steam for process energy needs. However, boilers are highly susceptible to the following problems:

Problems:

• Scale Formation on Tubes: Mineral deposits impede heat transfer, leading to decreased efficiency and risk of overheat.

• Internal Corrosion: Occurs as a result of dissolved oxygen or unstable pH damaging internal metal surfaces.

• Carryover Steam: Steam carries water particles or chemicals, can damage turbines or distribution pipes.

• Low Boiler Efficiency: Caused by scale buildup, incomplete combustion or sub-optimal operation.

Product Solution:

• Scale Inhibitor to prevent scale formation.

• Oxygen Scavenger binds free oxygen.

• pH Booster maintains boiler water pH balance.

• Antifoam Agent reduces carryover-causing foam.

• Operator Training to make boiler operation more efficient and safe.

2.2. Reverse Osmosis (RO)

Reverse osmosis is used to purify water by filtering out microscopic contaminants. However, RO systems are very sensitive to fouling.

Problems:

• Membrane Biofouling: The growth of microorganisms on the membrane causes clogging.

• RO Membrane Scaling: Mineral deposits reduce membrane permeability.

• Flux Decrease: The ability of the membrane to filter water decreases.

• High Pressure Drop: Due to dirt buildup on the membrane.

Product Solution:

• RO biocide to kill microorganisms.

• Antiscalant prevents mineral deposits.

• Membrane Cleaner for periodic cleaning.

• pH Adjuster adjusts feed water conditions.

2.3. Cooling Tower

Cooling towers serve to lower the temperature of the circulating water from the process. However, it is also susceptible to microbiological contamination and corrosion.

Problems:

• Algae growth: Open water is prone to algae growth.

• Pipe Corrosion: Occurs due to oxygen and aggressive chemicals.

• Scale on Heat Exchanger: Lowers cooling efficiency.

• Legionella Bacteria: Harmful bacteria that thrive in warm, stagnant water.

Product Solution:

• Cooling Tower Biocide to control microorganisms.

• Corrosion Inhibitor prevents corrosion of pipes and metals.

• Scale Inhibitor to prevent scale formation.

• Dispersant keeps solids from settling.

2.4. Clarifier

Clarifier functions to separate solid particles from liquids. Problems with clarifiers can impact the cleanliness of process water and effluent.

Problems:

• High water turbidity: Lowers process water quality.

• Suspended Solid Excess: Particles are not filtered properly.

• Flocs Not Formed: Low coagulation effectiveness.

• Dirty Water Overflow: Due to clarifier capacity being exceeded.

Product Solution:

• Coagulant PAC helps agglomerate particles.

• Flocculant Polymer enlarges flocs for easy settling.

• pH Adjuster maintains ideal conditions for the coagulation process.

• Clarifier Aid increases the efficiency of the separation process.

2.5. WWTP (Wastewater Treatment Plant)

Wastewater treatment plants are essential to comply with environmental regulations. The effluent from the palm oil process is rich in organic matter and oil which must be treated properly.

Problems:

• High BOD COD: The effluent contains a lot of organic matter.

• Excess Oil & Grease: Waste from lubrication and cleaning processes.

• Fluctuating pH: Difficult for biological processes.

• Sludge Bulking: Activated sludge develops abnormally, causing poor separation.

Product Solution:

• Bacterial Nutrient to strengthen decomposing bacteria.

• Oil Water Separator separates oil from wastewater.

• pH Buffer stabilizes system pH.

• WWTP Defoamer reduces excess foam in aeration.

2.6. Demineralization Plant

Used to produce ultra-pure water, e.g. for high pressure boilers and pharmaceutical applications.

Problems:

• Resin Fouling: The resin is contaminated with organic matter or heavy metals.

• Resin Capacity Decreases: Resin is saturated or damaged.

• Ineffective Regeneration: Regeneration does not restore full capacity.

• Silica Breakthrough: Silica is not absorbed properly.

Product Solution:

• Resin Cleaner to clean the resin from contaminants.

• Cation Resin and Anion Resin as ion exchange media.

• Regenerant (HCl/NaOH) for chemical regeneration of resin.

3. Conclusion

Every equipment in the palm oil industry has an important role that is inseparable. Problems that arise in each process unit can affect the overall smooth operation. Therefore, technical and chemical solutions must be designed thoroughly, starting from the selection of the right chemical products to improving operator competence.

Implementing the right solutions also helps companies maintain energy efficiency, reduce operating costs, and ensure compliance with environmental regulations. Investing in water control systems, equipment protection, and technical training is a wise move to maintain the sustainability of the palm oil industry in the future.
