Vol. 25, no. 2

36--58

The purpose of this paper is to introduce basic principles of benchmarking and explain the methodology to set the specific energy consumption (SEC) target for the beer and beverage industry in Vietnam to evaluate performance, support decisions, and energy efficiency (EE) improvement. Energy benchmarking management method is used to assess EE performance. This study also presents the SEC methodology as a guide for Vietnam enterprises in the brewery sector on how to manage the EE consumption and to comply with the legal energy consumption quota in the beer and beverage production. The study supports the enterprise in how to determine the SEC and support for national EE is essential to the promotion and deployment of practical energy saving solutions and compliance with the SEC through a suitable energy-saving target. In addition, this paper is introducing the original SEC calculation in three cases of production in the beer and beverage industry including producing beer only, producing beverage only, and producing both beer & beverage in the context of Vietnam.

Improving the energy efficiency of large grinding mills is of great importance to reduce the energy cost of mineral processing. The ratio of SAG mill to ball mill’s energy consumption varies greatly among SABC operations. Thus far, very few research studies have been conducted to demonstrate how the SAG mill or ball mill responses to the change of circuit energy distribution in terms of comminution efficiency. The present study investigated the energy performance of an operating SABC circuit at variable circuit energy distributions. An energy benchmarking model was used to assess the comminution energy efficiency of SAG mill, ball mill, and overall circuit. It is found that the target SABC circuit achieves the highest overall energy efficiency when 37.6% of the total circuit energy is distributed to the SAG mill and 62.4% to the ball mill. The maximum energy efficiency of this SABC circuit is approximately 25% when compared to the minimum practical energy required to carry out an equivalent comminution duty. The study also showed that the ball mill is more sensitive to the variation in circuit energy distribution than the SAG mill.
