Domestic wastewater heat recovery
, 2017 The aim of this thesis is to study and explain the purpose and the function of drain water heat exchangers. The thesis goes over theory behind heat transfer and heat exchangers and presents the general solutions of domestic drain water heat recovery systems. Systems gone over in detail are the different general shower drain water heat recovery systems.

AIChE Journal, EarlyView.ABSTRACT Conceptual process design combines discrete configuration choices with continuous operating decisions, often yielding difficult mixed‐integer nonlinear or simulation‐based optimization problems. This work presents an exploratory computational assessment of Ising‐based solvers, simulated annealing, quantum annealing, and entropy computing, as ...

Modelling heat recovery potential from household wastewater
, 2019 There is a strongly growing interest for wastewater heat recovery (WWHR) in Sweden and elsewhere, but a lack of adequate tools to determine downstream impacts due to the associated temperature drop.

Horizontal wastewater heat recovery heat exchanger, a model
, 2019 The residential and service sector amounts to approximately 40 percent of Sweden’s entire energy demand. In which 90 percent of that is used by households and non-residential buildings. All in all about 80 TWh are used for heating and the provision of hot water in households and non-residential buildings. Since heating has always been such a large part

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT This study presents the first experimental liquid–liquid equilibrium (LLE) data for quaternary systems composed of refined olive pomace oil, oleic acid, ethanol, and water at 303.15 K. These data are essential for the design and optimization of solvent‐based deacidification processes, particularly for oils with high free fatty acid (FFA ...

Optimising thermal energy recovery, utilisation and management in the process industries [PDF]
The persistent increase in the price of energy, the clamour to preserve our environment from the harmful effects of the anthropogenic release of greenhouse gases from the combustion of fossil fuels and the need to conserve these rapidly depleting fuels ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.

Steam Saving by Waste-Heat Recovery from Pulping Wastewater
JAPAN TAPPI JOURNAL, 2007 三菱製紙（株八戸工場では，当社のフェニックスプランに掲げるコストダウンテーマに則り省エネルギー推進を緊急課題として進めている。運用体制として，工場エネルギー活用委員会及びISO14001幹事会の会議委員を共通化して取組を連係させることにより，リアルタイムに省エネ効果を把握しながらエネルギー原単位の向上に取り組んでいる。今回は，平成18年11月に運転開始した排水廃熱回収設備の省エネ効果について紹介する。冬期の水温低下によって抄紙工程における蒸気使用量の増加を抑制することを目的として，従来パルプ系排水の冷却塔から大気放出していた廃熱を回収利用することによって，抄紙工程の清水温度をアップさせた。これにより，工程蒸気原単位が大幅に向上した。
