“…In addition, there were other oil contaminated wastes including hydraulic oil, oily rags, sewage sludge, and rolling mill sludge (approximately 603 tons/year). With the heating values of oil sludge and oily wastes ranging from 14–44 MJ/kg (Qin et al., 2015), the energy recovery of the oily wastes at the facility is expected to replace about 1100 tons of biomass (rice husk pellets) used for the steam boilers (the heating value of rice husk pellets ranging from 15.129 to 17.589 MJ/kg (Tokan et al., 2016). The economic benefits from the implementation of this BAT are expected to be approximately $100,000 saving per year for the waste treatment services (the waste treatment cost of oily wastes was approximately 17 cents per kg), and approximately $72,000 additional saving per year for the energy recovery of oil‐containing sludge and the reduction of biomass use (the market price of rice husk pellets was $65 per ton).…”

The cold rolled coil manufacturing is one of the steel making processes with great environmental concerns due to the high energy consumption and greenhouse gas emissions, significant wastewater discharge, and hazardous waste disposal. A large number of technical solutions have been introduced to improve energy efficiency and environmental sustainability in the steel rolling sub-sector, particularly the best available techniques (BATs) adopted by European IPPC Bureau (2001). In this study, fuzzy analytic hierarchy process and linear goal programing are combined in the development of a multi-criteria decision support system for evaluating and selecting best available techniques (BATs) in the cold rolled coil manufacturing industry.The proposed approach comprises of four steps and results in the rankings of the potential BATs for the cold rolled coil installations. In a case study of a cold rolling mill in Vietnam, amongst eleven BATs that were recommended for the installation, two BATs of the highest priority were further analyzed, including: (1) improving the spent degreasing baths and the alkaline wastewater treatment system using membrane technology; and (2) recovering spent emulsion to supply fuels for the steam boiler. It is expected that the application of these BATs can enhance environmental performances and significantly reduce energy cost for the steam boiler during its operation.

The Method of Obtaining Amorphous Nanosized Silicon Dioxide from Rice Production Waste

et al. 2019

View full text Add to dashboard Cite

The method of using rice husk, which is a rice production waste, as a raw material for the production of silicon dioxide as an alternative to synthetic silicon dioxide – aerosil is considered. A low-energy process for extracting silicon dioxide and cellulose from the husk by alkaline digestion in an NaOH solution was proposed, followed by treating the black liquor with an acid solution and calcining the precipitate at 575 °C during 5 hours. The yield of inorganic products from rice husk is determined based on the ash content of the pulp. It was shown that the product obtained mainly consists of silicon dioxide (SiO2) of amorphous structure, has an average particle size of less than 100 nm, which makes it possible to characterize it as nanosilica. At the same time, silicon dioxide consists of 51.7 % silicon and 48.3% oxygen against theoretical amounts of 30.4 % silicon and 69.6 % oxygen, respectively. The output of silicon dioxide is 8.8 % by weight of rice husk. At the same time, the process allows to obtain another valuable nanocellulose product.
