Shrijee Biogas

Established in 1976, Shrijee is one of the world’s leading suppliers of modern sugar mills, sugar refineries, sugar machinery and alcohol plants.

Shrijee has successfully completed a 1,500 TCD sugar mill project in Zambia on a turnkey basis. Shrijee is also well-known for specialty steam saving sugar machinery that results in enormous savings and efficiency gains for sugar mills.

Shrijee has successfully executed 39 turnkey Process House projects for sugar mills and 25 Boiling House expansion projects. Shrijee has also successfully executed 7 turnkey sugar refinery projects. Shrijee has supplied sugar machinery to more than 30 countries.

Shrijee is offering complete biogas plant services in technology collaboration with a renowned German company – J&F Biogas.

 

Shrijee’s Technology Partner: J & F Biogas

Germany is the world’s leader in biogas plants. Therefore Shrijee decided to bring the best of German biogas technology to India. Shrijee’s technology partner J&F Biogas has more than 35 years of experience in setting up biogas plants using various organic feed stocks in Europe and International markets.Their solutions are based on state-of-the-art German technology.

Together Shrijee - J&F Biogas offer world-class design and engineering services for constructing biogas plants using organic feedstocks. Biogas generated can be used for power generation or upgraded to BioCNG. Every plant we build is designed and built after understanding the specific needs of our customers.

J&F Biogas is managed by two experienced biogas professionals Joseph Vimal & Dr. Hans Friedmann.

What is Biogas?

Biogas is formed when bacteria break down organic material in the absence of oxygen, also called anaerobic digestion. Typical biogas composition consists of 55-60 % of CH4, 30-35 % of CO2, 1-3 % of H2S and 1-2% Moisture. Raw biogas can be upgraded to BioCNG/CBG (compressed Biogas) by using suitable upgrading technology. The biogas once upgraded will have CH4 > 95% and CO2 < 5%, which can be used as vehicle fuel or for various industrial applications or as replacement for LPG.

Biogas an all-rounder

Biogas is a true all-rounder; raw gas generated during fermentation process can be used for various applications. Biogas can be used for generating power and heat or purified to produce bio-methane/BioCNG. The digestate obtained after the fermentation process can be further used as high value organic solid and liquid bio-fertilizers rich in nutrients. Organic fertilizer contains adequate quantities of N, P, K and several micronutrients essential for plant growth.

The filter cake specialists

Other than commonly used organic wastes we specialize in offering solutions for setting up biogas plants using filter cake/press mud as feedstock. Press mud also called as Filter cake is one of the by-products generated during the sugar manufacturing process. Amount of filter cake generated in a sugar mill varies depending up on the crushing capacity of the mill and crushing season. Filter cake is a soft, spongy, amorphous and dark brown material containing sugar, fiber and coagulated colloids including cane wax, albuminoids, inorganic salts and soil particles. Filter cake is suitable for anaerobic process as the sugars in filter cake are easily degradable substrates. We have carried out number of years of research and development programs to study and commercialize filter cake-based biogas plants.

Biomethane/BioCNG  

Raw biogas once purified is equivalent to the quality of natural gas. Purified biogas can be bottled into cascades and transported to end user location or the purified gas can be directly injected in to the natural gas grid. The gulf between domestic demand and supply of natural gas is widening is many countries including India. Domestic production of natural gas is gradually decreasing across natural gas producing countries. Imports of liquefied natural gas (LNG) by developing countries and energy deficit countries will soar in the next decade to fuel the expanding economies. With all these uncertainties and rising costs on LNG imports, domestically produced biogas would provide a cost-effective alternate to natural gas.
