Summary

In this video, the presenter discusses the practical formulas used in the palm oil mill industry, focusing on steam distribution and its role in processing fresh fruit bunches (TBS). The video explains how steam is generated by boilers, converted into electricity through turbines, and used for various processing tasks such as sterilizing TBS and heating oil extraction tanks. Key calculations for steam, water, and fuel needs are shared, including how to determine energy output from the boiler and appropriate turbine selection. The video is a detailed, technical guide for those interested in palm oil mill operations and calculations.

Takeaways

• 😀 The channel introduces practical formulas used in palm oil mill operations, focusing on steam distribution and energy generation.
• 😀 Steam is generated by boilers, which are then used in turbines to produce electricity by converting steam pressure into rotational energy.
• 😀 The output steam from turbines is stored in a back-pressure vessel (BPV), which supplies steam to various processes like sterilizers for fresh fruit bunches (FFB).
• 😀 Steam is also distributed for heating purposes, including for oil extraction and kernel processing, ensuring the desired output from palm oil mills.
• 😀 A practical formula is provided: to process 1 ton of FFB, 0.55 tons of steam is required.
• 😀 For example, a palm oil mill processing 60 tons of FFB per hour will need 33 tons of steam per hour, calculated using the formula.
• 😀 Water is needed for boilers in the palm oil mill, with 1 ton of steam requiring 1 ton of water, meaning the mill needs 33 tons of water per hour for steam production.
• 😀 The palm oil mill's boiler fuel requirement is calculated using a practical ratio, with fiber consumption being 0.2 times the steam requirement and shell consumption being 0.1 times the steam requirement.
• 😀 For a mill processing 60 tons of FFB, it would require 6.6 tons of fiber and 3.3 tons of shells per hour to meet steam production needs.
• 😀 The electricity generated by the turbine is calculated by dividing the boiler capacity by the specific steam consumption (SSC) of the turbine, providing the total power output.
• 😀 An example calculation shows that a boiler with a 45-ton per hour capacity, using a SSC of 25 kg per kilowatt, can generate 1800 kilowatts of power, guiding turbine selection for the mill.

Q & A

What is the main focus of the video?

The video mainly focuses on explaining the practical formulas used in palm oil mill operations, specifically in relation to steam distribution, energy generation, and boiler requirements in the production process.

What is the practical formula for steam consumption in a palm oil mill?

The practical formula for steam consumption in a palm oil mill is 0.55 tons of steam per ton of Fresh Fruit Bunches (TBS). This means for every ton of TBS processed, 0.55 tons of steam is needed.

How is the required steam per hour calculated for a palm oil mill?

For a palm oil mill with a capacity to process 60 tons of TBS per hour, the required steam per hour is calculated by multiplying 60 tons by 0.55 tons of steam, resulting in 33 tons of steam per hour.

How is the steam for the palm oil mill generated?

Steam is generated in a boiler, which heats water to produce steam. The steam is then used for various purposes within the mill, including powering turbines and heating equipment like sterilizers.

What is a back-pressure vessel (BPV) used for in the mill?

A back-pressure vessel (BPV) is used to collect the steam output from turbines, maintaining the pressure and ensuring that the steam can be redirected for further use in the mill's processes.

How is steam utilized in the sterilization process in palm oil mills?

In the sterilization process, steam is used to heat and cook the fresh fruit bunches (TBS), which helps in loosening the fruits from the bunches and preparing them for further processing.

What role does the bypass steam line (makeup steam) play in palm oil mill operations?

The bypass steam line, also known as makeup steam, is used to supplement the steam supply when there is a shortfall in steam generation, ensuring that the mill's operations continue efficiently.

How is the water required for the boiler in a palm oil mill calculated?

The water requirement for the boiler is directly related to the steam output. Since 1 ton of steam is equivalent to 1 ton of water, for 33 tons of steam per hour, the required water is also 33 tons per hour.

How is the fuel requirement for a boiler determined in a palm oil mill?

The fuel requirement for the boiler is calculated using a practical ratio, with fiber required at 0.2 times the steam output and shells (cangkang) required at 0.1 times the steam output. For example, for 33 tons of steam per hour, the mill requires 6.6 tons of fiber and 3.3 tons of shells per hour.

What formula is used to determine the power output from a steam turbine in a palm oil mill?

The power output is determined by dividing the boiler capacity by the specific steam consumption (SSC) of the turbine. For example, a boiler with a capacity of 45 tons per hour and an SSC of 25 kg/kW will produce 1800 kW of electricity (45 tons/hour * 1000 kg/ton * 25 kg/kW = 1800 kW).
