this paper is a preliminary communication of a study on removal and recovery of heavy metalsfrom industrial waste waters using electro-coagulation (ec) technique. the larger study envisages use of solarenergy for producing the d.c. current, and simple chemical methods of standard methods in chemistry like useof hydrochloric acid, hydrogen sulfide, collection of precipitate, incineration and get...

microbial cells have been successfully used as biosorbents to remove heavy metals from wastewater. in some cases, dead cells appear to offer more advantages than living cells in the removal and recovery of heavy metal ions from industrial wastewater. maintaining higher biosorption capability and understanding the biosorption properties of dead cells are the keys to heavy metal removal and recov...

since the pressure of hydrocarbon reservoirs drops due to production, in order to keep the production rate constant or increase enhanced recovery, few methods are used. one of which is gas injection to the reservoir. on the other hand, due to reduction in oil production potential of aghajari oil field, gas injection is highly required to pressurize and enhance oil recovery. there is a possibili...

The world's first Liquefied Hydrogen (LH2) Carrier which will transport LH2 from Australia to Japan has been built. At Japanese port, reducing the tank pressure be required for safe operation. However, reduction cause flashing, leading an excess of venting capacity or liquid leakage. Hence, purpose this research is clarify rate and behavior through experimental numerical approaches respectively...

Proper thermal management can improve the efficiency of hydrogen storage chains based on liquid organic carriers (LOHC). The energy and exergy efficiencies 24 LOHC chains, which are differentiated by two sources (SEL: from electrolyzer SINDU: industrial by-product), three consumers (CPEMFC: proton exchange membrane fuel cell, CSOFC: solid oxide CINDU: consumer), four pairs calculated thermodyna...

The aim of this work was to determine a cost-optimal design the distillation unit Andrussow process. For purpose, feed with mass flow rate 121 t h−1 and concentration ca. 2 wt % hydrogen cyanide (HCN) considered. An approach for process intensification developed goal achieve desired product qualities, while minimizing organonitrile accumulation in column. simple column established base case ext...

Significant volumes of wastewater are routinely generated during agro-industry processing, amounting to millions tonnes annually. In line with the circular economy concept, there could be a possibility simultaneously treating and recovering bio-energy resources such as bio-hydrogen. This study aimed model effect different process parameters that influence treatment recovery from agro-industrial...
