“…Pinch technology has demonstrated exceptional success in the works of Adnan et al (2017), Ajao andAkande (2009), andAdejoh et al (2013), in which considerable amounts of energy were recovered, resulting in a cost-effective design. In the works of and Tibasiima and Okullo (2017), better energy recovery was accomplished in the food industry, indicating that wherever heating and cooling occurs, there is a potential opportunity. Several literatures were reviewed on pinch analysis of units in the refinery, Ajao and Akande (2009) worked on "Energy Integration of Crude Distillation Unit using Pinch Analysis."…”

Most Nigerian refineries were constructed before pinch technology was developed, hence, the design were not optimal, leading to high energy loss. The objective of this work is to evaluate energy integration of crude distillation unit (CDU) of a refining and petrochemical company in Northern Nigeria using pinch analysis by utilising HINT software. Minimum heating and cooling demand of 32251.1 kW and 29637.9 kW at the pinch point of 506.5 K was evaluated from the composite curve, grand composite curve and the cascade diagram. The region of overlap in the composite curve indicates a total of 108,945 kW as the possible energy that can be recovered in the process. Existing utility demand of the unit was 96,873.5 kW, after heat integration it reduces to 61,889 kW, this showed 36.11 % energy saving with a total operating cost of US$4,560,766.5 that could be saved (annually). Minimum approach temperature (DTmin) analysis results showed an optimum DTmin of 15 K which resulted in a total annual cost of US$6,715,700. Furthermore, the analysis showed the effect of DTmin on energy, area, minimum number of units and cost targets. The design objective of the retrofit heat exchanger network (HEN) was set toward maximum energy recovery. A total of twenty (20) heat exchangers made up the new network, which comprises of twelve (12) process to process heat exchangers, two (2) heaters and six (6) coolers.

“…The process of determining this minimum is referred to as trade-off between energy cost and capital cost in economic analysis of chemical plants. The *Corresponding author: abubakara@abu.edu.ng doi: http://dx.doi.org/10.4314/njtd.v17i3.5 minimum is known as optimum annual total cost and the minimum temperature difference at which this optimum is obtained is known as optimum minimum temperature difference (Attarakih et al, 2013;Rokni, 2016;Tibasiima and Okullo, 2017). Next is the determination of existing annual energy cost ( ) of the FCC unit which was achieved by applying Equation (3) to the existing utility thermal data.…”

“…The technology is based on thermodynamic principles that provides a systematic approach for energy saving with a wide range of applications in many chemical processes (Yoro et al, 2019). Although the application of this technology is most pronounced in oil and gas industries (Marton et al, 2017;Akpa et al, 2018;Ulyev et al, 2018), its use can be found in bioprocessing industry (Anastasovski et al, 2107), sugar production industry (Barambu et al, 2017), brewing industry (Tibasiima and Okullo, 2017) and cement industry (Verma and Kumar, 2017). It has also been used in addressing project selection problem (Pritam et al, 2017).…”

Pinch technology is one of the most powerful methodologies of process integration that allows industries to increase their profitability through reductions in energy, water and raw materials consumption. In this study, reduction in the total annual cost of heat exchanger network (HEN) of Fluid Catalytic Cracking (FCC) unit in Kaduna Refining and Petrochemical Company (KRPC), Kaduna was determined. With the help of pinch technology, the reduction was achieved by first determining optimum minimum temperature difference by trading off energy cost and capital cost targets as a function of minimum temperature difference. Thereafter, the total annual cost obtained at the optimum minimum temperature difference was compared with total annual cost of existing design. The results of the analysis showed that the optimum minimum temperature difference was 12℃, the total annual costs of the existing design and the optimum-minimum-temperature-difference based cost were $8.7 and $7.1 Million respectively. This amounted to percentage reduction in the total annual cost of 18.4% which means that about $1.6 Million would been saved annually using the optimum minimum temperature difference to design the HEN of the FCC unit.

“…Rising energy‐related costs and environmental concerns have led breweries to search for techniques for the reduction of energy consumption 9 . Breweries have started to consider the concept of sustainability and cleaner production in their processes, rethinking the impact of activities on the environment and seeking strategies to minimize solid waste generation and emissions.…”

The production of beer is an energy‐intensive process, and due to the progressive global increase in its consumption, this has raised environmental concerns especially regarding energy‐related impacts. The study presented herein applied the life cycle assessment methodology to quantify the greenhouse gas emissions associated with traditional supply of electricity (electric grid) and heat (liquefied petroleum gas) to a craft microbrewery. It was then considered that electricity could be provided by solar photovoltaic (PV) panels, and heat by solar collectors, and these values were compared with traditional energy supply. Solar PV electricity resulted in 66% less emissions per kWhe consumed, and solar collectors yielded 95% less emissions per kWhth. It was verified that there is potential for climate change mitigation associated with energy transition in breweries, considering electricity and thermal energy.
