Asia`s Largest Oil and Gas Company Seeks to Lower its Own Rising Costs
Growing demand and higher prices for natural gas might seem like good news for Asia’s largest oil & gas company. But for giant, Sinopec -- the world’s fifth largest company -- significant gas price increases in China also impact the cost of its own gas processing operations. That’s why engineers from the Sinopec Nanjing Engineering Company (SNEC) sought innovative ...

Energy analysis in industrial districts: a statistics-based approach
Considering the particular structure of the Italian productive system, characterised by local concentration of a great number of small and medium-sized enterprises in industrial districts, this study aims at developing a "district-oriented" approach to energy analysis. A combination of statistical methods is proposed in order to describe similarities, variability and relations among different ...

Entropy generation metric for evaluating and forecasting aircraft energy management systems
A general Entropy Generation Minimisation (EGM) technique is applied to analyse the feasibility of energy recovery from aircraft avionics via thermoelectric (TE) devices. In employing this approach, a suitable control volume definition is chosen to evaluate the impact of an energy recovery system on the overall entropy generation of the aircraft over a mission. Only those systems which are ...

Energy recovery from waste by use of fluidized-bed technology
Revolving type fluidized-bed technology, developed by Ebara Corp., is installed in more than 100 facilities worldwide. The technology is applied for waste, coal and in situations where a conventional fluidized bed is difficult to use. Waste and/or coal can be treated and valuable energy can be recovered from a non-renewable source. This paper describes the application of the revolving fluidized ...

Regenerative snubber for UPS inverter
An uninterrupted power supply (UPS) is used to provide electrical power to a load during an emergency situation in which the main utility power is not available. UPS topologies are well known. The inverter plays the most important role as an element in the UPS system. Usually, pulse width modulated inverters with voltage control and waveform shaping are used in UPS. This paper proposes an ...

Maximum possible efficiency for energy recovery from low-grade heat sources
Gas-to-gas heat exchangers are increasingly being used to recover low-grade heat (or cooling) to reduce energy requirements for space heating, drying and other applications. The efficiency of heat recovery is often limited by practical considerations which could – in principle – be reduced or eliminated by development of new materials and technology. However, this paper posits a fundamental ...

Energy Recovery System - Case Study
Addfield collaborated with an energy recovery company and one of the UK’s largest landscaping and recycling companies to produce the innovative idea of creating energy from waste. Some things cannot be recycled so instead of sending these to a landfill they are incinerated and reused to create hot water and electricity. This is then used to heat and power the garden centre whilst ...

Oil sludge pyrolysis equipment
Oil sludge is a by-product of the petroleum production process that is mixed with water, oil, and solid sediment, and is a hazardous waste that can be harmful to humans and the environment. Proper disposal of oil sludge not only protects the environment but also creates fuel oil, which is why environmentally friendly recycled sludge has received much attention in various countries. Oil sludge ...

Case study - Oxidizer energy recovery options
Overview The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and energy ...

Role of primary sedimentation on plant-wide energy recovery and carbon footprint
The goal of this paper is to show the effect of primary sedimentation on the chemical oxygen demand (COD) and solids fractionation and consequently on the carbonaceous and energy footprints of wastewater treatment processes. Using a simple rational procedure for COD and solids fraction quantification, we quantify the effects of varying fractions on CO2 and CO2-equivalent mass flows, process ...

Recovering energy from biogas emission: the case of Mariana Mantovana landfill (Italy)
This paper deals with the analytic rating of the economic investment in an energy recovery plant for municipal waste, in relation to the estimate of its capability to exploit biogas production transformation, and sale of electricity production, and the Green Certificates. The approach entails the assessment of potential scenarios of biogas flare coming from its production forecasts, according to ...

Turning waste into wattage
How we are helping to meet the growing demand for waste energy recovery It’s a sign of the times that more and more companies and organisations are now looking at ways to capitalise on the waste material their production process produces rather than having to pay a third part to take it away for them. One reason of course is the high cost of scrappage. Another is the reduced availability ...

Anaerobic digestion of post-hydrothermal liquefaction wastewater for improved energy efficiency of hydrothermal bioenergy processes
Hydrothermal liquefaction (HTL) is a promising process for converting wet biomass and organic wastes into bio-crude oil. It also produces an aqueous product referred to as post-hydrothermal liquefaction wastewater (PHWW) containing up to 40% of the original feedstock carbon, which reduces the overall energy efficiency of the HTL process. This study investigated the feasibility of using ...

Case study - Waste heat generates steam and savings
OVERVIEW A coil coating facility purchased a new a 15,000 SCFM Regenerative Thermal Oxidizer (RTO) which had a nominal heat transfer efficiency rate of 90% thermal energy recovery. It was designed with supplemental fuel injection (SFI) which is used during low VOC loading conditions, to help save fuel cost. The facility was looking for additional ways to decrease their exhaust air temperature ...
