A comprehensive approach to energy efficiency should be implemented in improving oil and gas industry performance. A strong, corporate-wide energy management program is essential to this process. Cross-cutting equipment and technologies such as boilers, compressors, and pumps are common to most plants and manufacturing industries, and present well-documented opportunities for improvement. The production process may also be fine-tuned to produce additional savings.

Key word: energy efficiency, energy management, additional saving.

Комплексний підхід до енергоефективності може впроваджуватись задля покращення ефективності нафтогазової галузі. Для цього процесу важлива потужна корпоративна програма енергоменеджменту. Різні види обладнання та технології, такі як котли, компресори та насоси, є спільними для більшості виробничих галузей, а також добре зарекомендували себе у такому виді роботи. Вважаємо, щовиробничий процес слід налаштовувати та вдосконалювати, задля подальшого заощадження.

Introduction

Energy Management Systems (EMS) and Programs сhanging how energy is managed by implementing an organization-wide energy management program is one of the most successful and cost-effective ways to bring about energy efficiency improvements.    

Analysis of current research

The U.S. EPA, through the ENERGY STAR program, has worked with man of the leading industrial manufacturers to identify the basic aspects of an effective energy management program [1]. In this field are working also O. Barchatov, M.Karpash, B. Mishchuk, N. Myca and other.

The main research material

An energy management program creates a foundation for improvement and provides guidance for managing energy throughout an organization. In companies without a clear program in place, opportunities for improvement may be unknown, or may not be promoted or implemented due to organizational barriers. These barriers may include a lack of communication among plants, a poor understanding of how to create support for an energy efficiency project, limited finances, poor accountability for performance metrics or changes from the status quo. Even though energy constitutes a significant cost for industry, companies may lack a strong commitment to improve energy management.

The major elements in a strategic energy management program are depicted in Figure A successful program in energy management begins with a strong organizational commitment to continuous improvement of energy efficiency. This typically involves assigning oversight and management duties to an energy director, establishing an energy policy, and creating a cross functional energy team. Steps and procedures are then put in place to assess performance through regular reviews of energy data, technical assessments, and benchmarking. From this assessment, an organization is then able to develop a performance baseline and set goals for improvement.

Performance goals help to shape the development and implementation of an action plan. An important aspect for ensuring the successes of the action plan is the involvement of personnel throughout the organization. Personnel at all levels should be aware of energy use and goals for efficiency. Staff should be trained in both skills and general approaches to energy efficiency in day-to-day practices. In addition, performance results should be regularly evaluated and communicated to all personnel, and high performers should be recognized and rewarded.

Energy Monitoring and Control Systems

           The use of energy monitoring and process control systems can play an important role in energy management and in reducing energy use. These may include sub-metering, monitoring and control systems, which can reduce the time required to perform complex tasks, often improving product and data quality and consistency, and optimizing process operations. Typically, energy and cost savings are 5% or more for industrial applications of process control systems without updated systems in place [2]. Many refineries may already have modern process control systems in place to improve energy efficiency.

Conclusion

            Though energy management systems are already widely disseminated in various industrial sectors, the performance of these systems can still be improved, reducing costs and further increasing energy savings. For example, total site energy monitoring and management systems, as opposed to traditional monitoring and management of a limited number of energy streams, can increase the exchange of energy streams between plants on one site. Various suppliers provide site-utility control systems.
