Process and production enhancement in biogas generation

Project Title

Process and production enhancement in biogas generation

Project Area of Specialization Mechanical EngineeringProject Summary

Pakistan is facing a severe Energy crisis due to its heavy dependency on the import of costly fossil fuels, which ultimately leads to expansive electricity generation, a low power supply, and interruptive load shedding of both electricity and Natural gas. Also the   increased   use   of   fossil   fuels   for   energy   consumption   has   causes environmental problems both, locally and globally.

According to Pakistan council of Renewable Energy Technologies (PCRET’S), There are almost 51 million animals (Buffaloes, Cows, Bullocks) in Pakistan. Thus, 19.125 Million M3 biogas can be produced daily by anaerobic fermentation of dung through installation of about 3.825 million family size biogas plants, which could meet the cooking needs of about 50 million people. The total population of Pakistan is about 170 million, out of which 70% reside in the rural areas, which comes to be 98 million. Therefore we can meet the cooking / heating requirements of 44% rural masses from this single source of energy (biogas) besides, producing 57.4 million Kg of nitrogen enriched bio-fertilizer per day or 21.00 million tons of bio-fertilizer per year, which is an essential requirement for sustaining the fertility of agricultural lands as well.

Project Objectives

Utilization of available renewable energy resources within the country for production of electricity and domestic gas.

We will provide feasible solution/Efficient Energy source for farm houses and people living in different rural areas that instead of relying on government why not they utilize their available resources.

Project Implementation Method

The Project is suitable for community level and for farm houses where huge amount of  waste is being produced on daily basis. The  collection of waste is done on dailly basis and collected in a single place. The waste is dumped into the digester tank for production  process. Bio-Gas produced pass through the filter plant to remove carbondioxide and sulphur contents and then move towards for storage or transporation purpose.

Our targeted market/customers include

• Farm houses
• Geyser companies
• Domestic users
• Fertilizers companies

Benefits of the Project

• Renewable energy source
• Waste Management
• Reduces land and water pollution
• Production of nitrogen-rich organic fertilizers
• Alternate for gas and electricity in rural areas
• Prevents Health Problems & Biodiversity Loss

Technical Details of Final Deliverable

we were  use digestor tank of 300 liters capacity in which different batch processes being conducted. Due to some limitation of waste collection (just to cnduct study), tank was not filled to desied volume. Following data was collected from the batch processes  

Batch Processes:

Digestor	Ratio	Ingredients
Batch 1	1:1:0.5	10kg cow dung,10 kg fruit and vegetable waste,5 kg water
Batch 2	1:0.5:0.5:0.5	10kg cow dung,5 kg poultry waste,5 kg vegetable waste,5 kg sludge
Batch 3	1:1	Cattle dung along with sewerage water 12.5 kg of each
