The Chinese petrochemical industry is facing pressure to meet strict targets of energy consumption and carbon emission reductions. Water pumps are the primary equipment used in most chemical and agrochemical industries sectors since water is commonly used for cooling and heating purposes, but these pumps also consume a large amount of energy. Other uses of water pumps in these industries include producing steam for heating, preparing reaction media or absorptive reagents, rinsing products, and distilling. As for the electrical components of the water pump systems, current technologies of variable frequency drives and superconducting transmission lines are unable to increase the energy efficiency of these systems with a fixed load. However, the Balanced Wave Technology (BWT) is offered as a solution to overcome these limitations. In this report, a case study using a BWT optimizer is conducted on a closed loop water circulation system. Two BWTs are added to the individual motor-controlled section of each pump that is being used on the switchboard. For the first time, a detailed example was provided on how to implement option B of the International Performance Measurement and Verification Protocol (IPMVP) in China by evaluating the performance of BWT as an energy conservation measure. The evaluated periods included those of the baseline, post-installation, and actual performance of the optimizers. An average saving of energy of about 10.46% is recorded in a 5-week reporting period. On this basis, that annual electricity saved is estimated to be 66,447.18 kWh, which is equivalent to the emission of 68.94 metric tons of CO2e. This case study demonstrates in detail how option B of IPMVP can be implemented for BWTs applied on pumping systems. In addition to petrochemical production plants, other industries like textile and clothing sections, which are heavy users of water and electrical energy with fixed loads in the production processes of raw materials, fiber, yarn, and fabric, as well as textile-dyeing and final treatment, could benefit from applying this new technology.
The global supply chains in the Textile and Clothing (T&C) industry have been shaping by various forces, among them economic development policy is one of the strongest. Amid the rollout of the Chinese's new national development strategy-Belt and Road Initiative (BRI), major T&C companies see both opportunities and challenges in optimizing and restructuring the networks of their production facilities. One notable and growing trend associated with the BRI is the relocation of T&C manufacturing from China to ASEAN countries and establishment of new factories along the Belt and Road (B&R). Much has been examined about the BRI at the national level, yet little is known about how companies in the T&C industry have responded to this grand economic development plan.This study aims to explore from industrial stakeholders' perspectives, the factors that drive and hinder synergistic, mutually beneficial development of T&C production and trade among the B&R countries. To achieve this aim, it addresses the following questions: what are the challenges and opportunities faced by T&C companies establishing or relocating production to B&R countries, and what tangible actions have been taken by them?In-depth interviews were carried out with ten industry professionals from Hong Kong-based companies and government institutions involved with T&C trade in the Asian B&R countries, such as Bangladesh, Cambodia, Indonesia and Myanmar. The findings of this study highlight the importance of pursuing sustainable development. On one hand, there is full of potential for T&C companies to achieve cost-effective production along the B&R countries through harnessing economic policy and transport infrastructure that facilitate trade. On the other hand, T&C companies see challenges in managing culturally diversity in the workplace as opportunities for pursuing corporate development in a socially responsible manner.In sum, this study reveals mutual supportiveness of economic and social aspects of T&C production and trade.
