Making biogas 1

PART 1 -
 
1. INTRODUCTION

When someone speaks of biogas, which is usually referred to is the gas produced by anaerobic biological process (without contact with free oxygen), which consists of a combination of methane (CH4), carbon dioxide (CO2), Water in the form of vapor (H20), and some Other gases like hydrogen sulfide (H2S), nitrogen (N2), hydrogen (H2) and other types of gas in small quantities.
In shorter, biogas can be interpreted as a "gas produced by living things."

In this article tells a bit about the concept of biogas and Biodigester and will be told and documented regarding the manufacture and installation of plant (digester) biogas.
 
WHAT IS AND WHAT IS BIOGAS BIODIGESTER?
 
BIOGAS

Biogas is gas produced from anaerobic decomposition (without oxygen) or fermentation of organic material.

Types of Organic Materials

Gas production per kg of manure (m3)

Cow  / buffalo Manure

0,023 - 0,040

Pig Manure

0,040 - 0,059

Chicken manure

0,065 - 0,116

Human waste

0,020 - 0,028

 

 

Gas produced from the anaerobic process
