Research Paper | Mathematical and Technical Model Biogas Plant

Mathematical and Technical Model Biogas Plant with a Membrane Separator

ZhanatUmarova and SharipzhanEskendirov South Kazakhstan State University, Tauke-Khan avenue 5, Shymkent, Kazakhstan

Abstract. The given mathematical model describes biogas plant with a membrane separator. There is

separation of multicomponent gas flow in modules of hollow fiber membranes in co-flow and counter flow.
The solution of the system, modeled by us, can be made with the help of Runge-Kutta method, traced to
Cauchy problem. Counter current configuration with component gases, having high selectivity, requires more
computing time.
Penetration of gas mixture similar to biogas, consisting of three components: methane, carbon dioxide and
oxygen have been presented in correspondence with the experiment. The results of modeled gas separation
correspond to observed estimations well. The highest indicator has been achieved at counter current
configuration.

Keywords: Mathematical model, Membrane Separation, Biogas, Permeate, Retentate.

1. Introduction

Biogas production, as a source of energy, is increasing annually in most countries of the world, which do
not have natural gas. For these countries biogas employment as fuel for gas-engines, for producing electro
energy and heat as well have three advantages: first, it reduces dependence of its economy from importers of
natural gas; secondly, it realizes the international policy on carbon dioxide burst, thirdly, it supports its
producer economically.

Besides, insignificant content of harmful components, unlike natural gas, containing large volume of
sulphur compounds, creating significant expenditure in its purification, biogas contains from 45 up to 70% of
methane, from 30 to 45% of carbon dioxide and less than 10% of ammonia, hydrogen sulphide, nitrogen and
oxygen totally, and also insignificant amount of water vapour. To approximate biogas in quality to supplied
market natural biogas technological transformations are necessary. Separation of harmful substances [1],
drying and evolution of carbon dioxide, as inert one for constituents combustion, that is biogas enrichment
are the most important of them.

Biogas Project by Skidmore College student Peter McInerney

Biogas Project by Skidmore College student Peter McInerney



Peter McInerney created this biogas/anaerobic digestion project during a study abroad trip to Uzi Island in Zanzibar with the School for International Training, a program he learned about through Skidmore College. He was able to obtain funding through the Responsible Citizenship Task Force on campus during the 2010-11 Academic Year in order to fund the materials and build the project. This creates methane gas to be used for cooking in a home there by way of anaerobic digestion from food waste created by the residents.

News: construction of 100 bio-gas plants in Gujranwala will completed soon

construction of 100 bio-gas plants is in final stages in various villages of Gujranwala, District Coordination Officer Muhammad Amin Chaudhry said on Friday. He was speaking at the inauguration ceremony of a bio-gas production plant in Benka Cheema village in Gakhar.
The DCO said work on 45 plants had been completed. He said gas supply to respective villages had also begun form these plants. Work on another 400 plants would soon be started, he added.
DCO Chaudhry urged the livestock farmers and affluent people to come forward and cooperate with the administration in establishing more biogas plants. He said many more villages could benefit from the facility if plants could be established at all the 2,665 livestock farms in Gujranwala.
Citizens Community Board (CCB) chairman Mian Attaur Rahman, secretary Nasir Ghumman, coordinator Muhammad Israel and plant owners Rana Riasat, Rana Muhammad Yaqoob, Rana, Maqbool and Rana Abdul Ghani were present at the ceremony.
CCB chairman Rahman said plants were being set up on a public-private partnership model. He said 80 per cent of the cost of a plant was borne by the government and 20 per cent by the land owner. He estimated the cost of a plant at Rs160,000.
About the 100 under construction plants, he said the government had released Rs8.4 million of its share (Rs15 million) to the contractors.
The remaining Rs6.6 million would be released once construction was complete, he said.
CCB coordinator said the pressure of gas generated by these plants was 300 per cent more than Sui Gas.
He said the pressure remained constant up to 400 feet away
