Abstract

Various separation processes were used in the chemical industry along with their corresponding separating agents. The separation processes play a critical role in various chemical process industries, including the removal of impurities from raw materials, purification of products, separation of recycle streams, and removal of contaminants from air and effluents. Hence it can be intensified by integrating of existing and new unit operations, it offers a huge increase in efficiency and controllability, thereby saving a lot of raw materials and energy, reducing waste production, increasing yield and quality and improving production safety. This review, deals on the development and implementation of small scale continuous processes and processing systems helping chemical industries to get more out of their processes.

Keywords

Abstract

Mediator less dual chamber microbial fuel cell (MFC) using paper industry waste for energy generation and wastewater treatment was studied. The potassium permanganate as a cathode solution with paper industry wastewater the substrate source to an anodic chamber. Nafion membrane is used for exchanging proton. MFC was efficient in the removal of COD (85% removal). Energy generation will be 0.747 V to 1.12V .

Keywords

Abstract

Combustion of the fossil fuels at the current rate would contribute to the environmental crisis globally. Bio-fuel recognized as alternative to fossil fuels, India contributes to 27% of world's banana production. 25 to 40% bananas wasted due to bad handling, Waste banana can be used to produce bio-fuel. Production of bio-fuel is studied by enzymatic hydrolysis and fermentation by using Saccharomyces cerevisiae. Utilization of rotten banana is more suitable for bio-fuel production as renewable energy which could reduce the cost of initial process. Although several separation technologies are technically capable of removing volatile products from fermentation broth, distillation requires more energy and cost. Pervaporation has been used as an alternative to classical separation process as distillation. It is an attractive technology because of the potential to selectively separate volatile component and water. and energy intensive, economical, safer separation technology.Hydrophobic PTFE (Polytetrafluoroethylene) Membrane of porosity 0.2 micron is used for Pervaporation of Bioethanol-water. The separation processes have many advantages that can improve the total efficiency of bioethanol production refineries.

Keywords

Abstract

In present study sugarcane bagasse was used for production of bioethanol. In enzymatic hydrolysis, ―trichoderma ressi‖&―aspergillus‖ were used. Trichoderma ressi found relatively effective offering conversion up to 14% glucose in two days compared to three days for aspergillus. Fermentation carried out under optimized conditions with, S. cerevisiae produced 11.6% of ethanol. Considering the limitations of azeotropic mixture, pervaporation was used for the purification of ethanol. Hydrophobic Poly Tetra FluroEthylene (PTFE) was used for pervaporation. The study demonstrated membrane technology as promising, highly selective, cost&energy saving technology.

Abstract

This study was intended to observe the feasibility of developed swept tubular pyrolyzer for the production of bio-oil by pyrolysis of biomass such as cotton stalks. To study pyrolysis parameter, a 628 cm³ (ID 4 cm) swept tubular batch pyrolyzer was developed itself in our workshop. The effect of temperature (400 °C to 700 °C), particle size (0.3 mm, 0.35 mm, 0.425 mm, 1 mm) and time of pyrolysis of cotton stalk on the amount of bio-oil and bio char were investigated at atmospheric pressure condition with a heating rate of 5 to 6 °C/min and under the constant mild flow of N₂. The designed swept pyrolyzer has given the 42 % bio-oil yield and temperature and time of pyrolysis of cotton stalk showed pronounced effect on the yield of bio-oil, whereas particle size did not shown significant influence on the yield of bio-oil.

Abstract

The current issue of responsible environmental management adds pressure on the dairy industry to reduce demands for energy, chemicals and water. So from the CIP solution recover NaOH&HNO3 used membrane filtration techniques like nanofiltration and after that reconcentration using reverse osmosis. Nanofiltration reduced the COD content of the caustic washing solution by 76-90% depending on the concentration ratio used. The alkaline/acid content of the nanofiltration permeate was similar to the feed. By reverse osmosis treatment alkaline NF permeates were concentrate NaOH.
