Petroleum Conservation Research Association (PCRA) is a registered society set up under the aegis of Ministry of Petroleum & Natural Gas, Government of India. As a non-profit organization, PCRA is a national government agency engaged in promoting energy efficiency in various sectors of economy. It helps the government in proposing policies and strategies for petroleum conservation, aimed at reducing excessive dependence of the country on oil requirement. Over the years, PCRA has enlarged its role in improving productivity in use of various sources of energy.
The Energy Audit provides the vital information base for overall energy conservation program covering essentially energy utilization analysis and evaluation of energy conservation measures. It aims at:
- Identifying the quality and cost of various energy inputs.
- Assessing present pattern of energy consumption in different cost centers of operations.
- Relating energy inputs and production output.
- Identifying potential areas of thermal and electrical energy economy.
- Highlighting wastage’s in major areas.
- Fixing of energy saving potential targets for individual cost centers.
- Implementation of measures for energy conservation & realization of savings.
Benefits of Energy Audit from PCRA:
Petroleum Conservation Research Association (PCRA), under the aegis of MOP&NG, since its inception in the year 1978, has been actively engaged in formulating strategies to promote energy efficiency and conservation of petroleum products for sustainable development, energy security and environment protection.
PCRA has been the nodal agency in the country for many energy efficiency programmes across far and wide corner of the country penetrating to almost every sector of energy consumers viz. Industrial, Transport, Domestic and Agriculture etc. PCRA has a qualified and well experienced pool of manpower drawn from oil sector PSUs and to undertake such jobs. During the last 25 years, PCRA conducted more than 12,000 energy audits in small, medium and large industries.
The Board guidelines indicating the methodology for such an energy audit is given below. Possible stages for interaction/conference are also indicated.
- Collections of data on operational parameters, energy consumption both normal and electrical, coal and power quality etc., through a questionnaire.
- Study the existing plant capacities and their performance to assess plant operations.
- Study of the specific energy consumption (both thermal and electrical) department-wise and plant as a whole.
- Study of the power sources, distribution system and drive controls, load factor and efficiency of large motors (above 10 kW), process automations, plant illuminations etc.
- Collection of requisite data and analysis and identification of specific areas with potential for conservation of thermal and electrical energy.
- Field measurements of operational parameters and carrying out heat and mass balance.
- Study of limitations, if any, in the optimal use of thermal and electrical energy.
- Formulation of specific recommendations along with broad system concept for conservation of thermal and electrical energy.
- Preparation of capital cost estimates and establishing techno-economic feasibility for recommended measures.
- No investment and/or marginal investment by doing system improvements and optimization of operations.
- Major investment due to incorporation of modern energy intensive equipment and upgradation of existing equipment.
- Formulating tentative time schedule for implementation of the recommendation.
- Undertaking broad cost benefit analysis in terms of savings in energy consumption per unit of production and pay-back period.
- Follow-up with the industry on periodic basis to ascertain the level of implementation of recommendation and assist, if require, in implementation of the measures to achieve energy user efficiency.
Assistance required from Client Side:
- Nomination of one engineer as coordinator from client side and to provide the relevant data / record about equipment etc. (maximum available), during course of the Energy Audit. Any other requirement would be conveyed at site, as & when required.
- As and when required, the team of energy auditors will make visits in building / plant therefore arrangement of entry pass and gate pass for instruments carried by the team.
Preliminary Energy Audit
The Preliminary Energy Audit focuses on the major energy suppliers and demands usually accounting for approximately 70% of total energy. It is essentially a preliminary data gathering and analysis effort. It uses only available data and is completed with limited diagnostic instruments. The PEA is conducted in a very short time frame i.e. 1-3 days during which the energy auditor relies on his experience together with all the relevant written, oral visual information that can lead to a quick diagnosis of the plant energy situation. The PEA focuses on the identification of obvious sources of energy wastage’s. The typical output of a PEA is a set of recommendations and immediate low cost action that can be taken up by the department head.
Detailed Energy Audit
The detailed audit goes beyond quantitative estimates of costs and savings. It includes engineering recommendations and well-defined project, giving due priorities. Approximately 95% of all energy is accounted for during the detailed audit. The detailed energy audit is conducted after the preliminary energy audit. Sophisticated instrumentation including flow meter, flue gas analyzer and scanner are use of compute energy efficiency.
