In Romania, major focus and interest are currently expressed for the energy strategies domain. The increase of the energetic efficiency is therefore a main concern for the authorities. In the current paper the main factors which are leading to the increase of this energetic efficiency are highlighted. These are: CHP (Combined Heat Power), combined cycles, the use of RER (reusable energy resources). The article also contains a classification of the RES (secondary energy resources) as function of the thermodynamic agent nature and/or its thermodynamic state. The theory and concepts are strengthened with relevant examples which have direct applicability in the oil and gas industry.

This paper depicts certain thermodynamic processes possibly involved in the oil industry specific activities operation and/or proper equipment maintenance. On this basis we present a series of courses of action in performing processes like oil storage and transportation, aiming the thermal energy consumption reduction.

The present paper first discusses a calculation model for the complete combustion of fuels � with the minimum amount of air needed � whose volumetric and mass composition is known. It then describes evaluation models for the heat resulting from fuel combustion, i.e., superior and inferior caloric power value. In this context, the carbon dioxide emission factors for fuel and biofuel combustion, respectively, are evaluated. The results obtained have allowed a comparative analysis regarding carbon dioxide emission.

The security of the functioning systems represents, through the four specific components (security, availability, reliability and maintenance), a basic component of the processing requirement. Monitoring of all specific intrinsic and operating parameters of oil and gas pipelines can be technically detected and diagnosed by: –existing defects; –rapid and effective intervention to eliminate the damage, if they occurred. To establish the maintenance programs that can ensure the proper functioning of the gas pipelines, it is necessary to establish their technical status. The research done helps reduce the risk of gas pipeline damage.
