This research, with the introduction of productivity as an alternative to the outcomes, presents a mathematical model for performance-based budgeting in order to allocate budget to productivity criteria. New trends in budgeting are process-oriented, so the productivity is suitable for PBB. This research presents a mathematical model for PBB. The model has been designed by Chebyshev's goal programming technique. Data for calculating productivity indicators were collected from gas refineries of Iran in 2011–2015 and analyzed by Excel and GAMS software. Then, the model was tested for determining the 2016 budget of those refineries. The model was solved by LINGO software by linking it to Excel. The solution of the model reduced 1.47% of the total refinery's budget compared with the actual budgets for 2016. The results of this study showed that the presented model provides significant improvement in the level of achievement of goals and the objective function. Saving costs and collecting funds from low-productivity units and directing them to high productivity is a strategic and important policy. Manuscript profile -

EPA's AP 42 documents provide the most comprehensive emission factor system for all industries based on process type, fuel, and control types. Target of this study, wasto investigate concentrations, emission factors of SO2, NO2 and CO in Ilam gas refinery.Method: In this study, concentrations of SO2, NO2 and CO and other required parameters such as temperature, pressure, flow rate and diameter of the 6 main stacks were measured by direct field measurements by Testo 350 XL. By results of these measurements and measurements of previous years in the refinery, the mean average for the two normal scenarios and the worst condition, and then the emission values were calculated. Data analysis was carried out with a confidence level of 95%.Findings: The estimated secondry, hourly, daily, monthly, and annual emissions from Ilam gas refinery was calculated and analyzed based on 2 normal and worst-case scenarios. Field measurement of flue concentrations showed that the highest concentrations of carbon monoxide (3565 ppm) and sulfur dioxide (5099 ppm) relates to SRU1 unit, the highest produced nitrogen dioxide (188 ppm) produced by SRU2, 1396 were the most polluted year according to the measured gases. The results of environmental measurements showed that CO at the sewage station is, 4/12 ppm and in Mehran road with an undetectable amount, the lowest amount of NO2 in the Chegae with 0.6 and Mehran road with the undetectable, the lowest amount, the amount of SO2 at the laboratory point with a maximum of 0.13 ppm and in the housing camp with an undetectable amount, the lowest It was.Discussion and Conclusion: Considering that the amount of environmental pollution and concentration of pollutants in the production units are more significant. So, planning for corrective actions to reduce emission of pollutants in production units, seems to be necessary. As well as the recovery and reduction of feed of flaring, can have a significant impact on the emission of pollutants. Manuscript profile -

Method: In this study, the risks related to the storage tanks and flare were identified and prioritized. Then, the consequences of the identified risks for the selected scenarios comprising radiation due to fire, the pressure due to an explosion, and leakage of toxic material were modeled using the Process Hazard Analysis Software Tool (PHAST) for possible accidents. In this study, the ETBA method identified 70 risks, among which seven of them were in the unacceptable range, in which four risks were associated to the spherical storage tanks, loading (two risks), and the cylindrical storage tank and the flare were each assigned one risk. The risk associated with the heat energy of the spherical and cylindrical storage tanks and the flare were significant. Subsequently, the consequences of four scenarios including the sudden release of gas from the spherical storage tank, leakage of gas condensate from the cylindrical tanks, leakage of Liquid Petroleum Gas (LPG) from the loading arm, and flare-off were selected for simulation. Discussion and Conclusion: In the first scenario, the radiation resulting from fire and the shockwave of the spherical storage tank explosions affected a wide area of the refinery. In the second scenario, leakage of condensate gas from the adjacent wall to the cylindrical storage tanks is of certain significance. In the third scenario, the location of the loading platform is unsuitable. In the fourth scenario, the height of the flares is suitable and the release of toxic and flammable gases does not pose a significant consequence for the installations and people in connection. Reviewing the fire extinguisher systems, constant assessment of the lightning arrestors, and conducting firefighting drills are among the recommendations of this study. Manuscript profile -

Therefo MoreIn industrial plants such as gas refinery, sustainable production is a top priority. The cooling pump plays an essential role in a gas refinery. If the pump is out of service (and if the replacement pump is not ready), the refinery will be shut down immediately. Therefore, the sensitivity of this equipment is very critical in terms of operation and process and should be maintained in the shortest possible time. The status of this equipment is monitored regularly using vibration technique. In a period of time, after the vibration analysis, a decision was made to modify the base plate of the pump as well as to reduce the stress; piping arrangement of the pump was redesigned and modified. These modifications resulted in a reduction in vibration rate from 8 mm / s to 5 mm under new conditions. Also, in order to investigate the effect of fluid behavior on pump performance, in a separate project, flow fluid was simulated by computational fluid dynamics (CFD), within the impeller and pump casing.

The risk was studied and then the results were modeled using PHA-pro software. The results showed that out of 15 identified risks, 7 had a risk number higher than 14, which can be said that approximately 46% of the activities were in the high risk area. Most of the values related to checking the seals were in the sulfur recycling unit, which resulted in spraying sulfur in the area outside the seals and causing burns and death. The corrective action was the use of face shields, work clothes and fireproof gloves. The next activity that had a high risk number was loading LPG, which resulted in improper installation of connections, gas leaks, fire / explosion, and damage to people and equipment. Be. It is clear that after the implementation of the control proposals, the number of high-risk cases has been reduced from 7 to 1, and the modeling bar chart has been moved to a safe area. In other words, before the control measures, 46% of the activities were in the high risk zone, 26% in the medium risk zone and 28% in the low risk zone. After the control measures, only 6% of the risks were in the high risk zone and 13% in The middle zone and 81% of them were in the low or safe risk zone. Manuscript profile -
