On account of severe water pollution condition, this paper combines refinery and chemical enterprises pollution reduction and linear programming method, builds a selection optimization model of water pollution emission reduction measures in refining and chemical enterprises, and puts the above model into practice to validate its validity and reliability. According to the case study, the maximum emission reductions of COD and NH3-N for refining and chemical enterprises was 6481.50 and 549.51tons, which has improved 29.63% and 9.90% compared with the target reductions, respectively. The optimal emission reduction scheme is choosing MycelxTMtechnology, and COD has installed on the Delay catalytic unit, while NH3-N has installed on the Sulfur recovery unit. This model could provide not only the maximum emission reduction and optimal scheme, but also the decision support of emission reduction for refinery and chemical enterprises during "the 12thFive-Year Plan".

On account of severe water pollution condition, this paper combines structure emissions reduction, engineering emissions reduction and management emissions reduction (namely SEM emissions reduction), builds an optimization model for total amount control of regional water pollution, and puts the above model into practice to validate its validity and reliability. According to the case study, the emission reduction of COD and NH3-N are 43.94 and 7.09 (104 tons), respectively. The optimal total costs of reduction is 36.89 (billion yuan), which decreases 7.47% than the existed recommended scheme (39.87 billion yuan). This method can be used for providing technical support and thus achieves the 12th Five-year goals of the environment protection plan more effectively.

Combining environment policies of structure emissions reduction, engineering emissions reduction and management emissions reduction, this paper uses an interval-fuzzy linear programming and builds an optimization model for total amount control of regional water pollution, on account of severe water pollution condition. The developed model is applied to a case of Hunan Province to validate its validity and reliability. The optimal result demonstrated that the emission reduction of COD and NH3-N are [43.39, 47.57] and [7.05, 7.64] (104 tons), and the optimal total costs of reduction is [35.11, 37.35] (billion yuan), which decreases 6.32~11.20% than the existed recommended scheme (39.87 billion yuan). This method can be used for providing technical support and thus achieves the 12th Five-year goals of the environment protection plan more effectively.

Abstract This work investigates the level of noise in oil and gas fields and its impact on the health of the operators, visitors, and trainees, as well as controlling noise within acceptable levels in the workplace by proper measurement. Risk assessment is done to identify the associated hazards of particular activities or tasks in the fields. Sulfur recovery unit (SRU) at a gas processing complex is the case study which consists of three production plants.Many master points were randomly selected, where workers are present. Therefore, in order to sufficiently measure the level of noise, the measurement of the noise level was performed in different periods of time within the years 2014-2017 and was compared with OSHA limits. Results show that most of the gathered noise field data were beyond the permissive limits of OSHA (85 dB). Ishikawa Diagram depicts the analysis of cause and effect of over limits readings which are rotating machines, maintenance activities, steam leakages, fluid flow, and gas flaring.Finally, the risk assessment presents that such workplaces may present a high noise risk score that could harm the workers.

Abstract This paper presents the results of testing the applicability of the MIKE Basin model for simulating the efficiency of scenarios for reducing water pollution. The model has been tested on the Olšava River Basin (520 km2) which is a typical rural region with a heterogeneous mix of pollution sources with variable topography and land use. The study proved that the model can be calibrated successfully using even the limited amount of data typically available in rural basins. The scenarios of pollution reduction were based on implementation and intensification of municipal wastewater treatment and conversion of arable land on fields under the risk of soil erosion to permanent grassland. The application of simulation results of these scenarios with proposed measures proved decreasing concentrations in downstream monitoring stations. Due to the practical applicability of proposed measures, these could lead to fulfilment of the water pollution limits required by the Czech and EU legislation. However, there are factors of uncertainty that are discussed that may delay or limit the effect of adopted measures in small rural basins.

The Electrification ratio in Indonesia is 89.10%, which means there are 7, 245,728 of 66, 489,400 households don’t have access to Electrical Energy Sources (EES). Kupang Regency is one of the Regency in Indonesia which has a low electrification ratio. 29,542 of 78,109 households haven't access to EES spread over 29 villages (electrification ratio of 62%). Solar Photovoltaic in Kupang Regency 5 MWp capacity has been operating but directly connected (On-Grid) to the State Electricity Company (PLN), it is not able to help rural communities that are difficulties to reach due to its geographical conditions. The aim of this research was design the electrification ratio optimization model with the consideration of CO2 emission reduction using Solar Photovoltaic. The method of research using dynamic modeling approach. The result of the research shows that electrification ratio can be achieved optimum estimated in 2020-2021 if the addition of capable power each year 4,000 kW. The addition of capable power 2,000 kW/year, can reach the optimum electrification ratio in 2023-2024 and if the addition of capable power is only 1,000 kW/year, the optimum electrification ratio can be achieved in 2030-2031. Diversification of DPG into Solar PV can reduce CO2 emissions by 98.8%.

Controversy is common on environmental issues, with carbon taxation in Canada a current example. This paper uses Canada as a case study for analysis based around balanced presentation, a technique developed some time ago, yet largely forgotten. Using the method, analysis is shifted away from the point of controversy to a broader quantitative question, with comparative data employed from official government sources. Simple quantitative analysis is applied to evaluate emission trends of individual Canadian provinces, with quantitative metrics to identify and confirm the application of relevant emission reduction policies by individual jurisdictions. From 2005 through 2019, three provinces show consistent downward emission trends, two show consistent upward trends, and the remaining five have no trends, showing relatively “flat” profiles. The results clarify, in terms of diverse emission reduction policies, where successes have occurred, and where deficiencies or ambiguities have existed. Neither carbon taxation nor related cap-and-trade show any association with long-term reductions in overall emissions. One policy does stand out as being associated with long-term reductions, namely grid decarbonization. The results suggest a possible need within Canada to rethink emission reduction policies. The method may be relevant as a model for other countries to consider as well.
