The ATP content of lodgepole – jack pine (Pinus contorta × banksiana) hybrids in the cordillerean–boreal transition zone was monitored during sulfur dioxide fumigations. Foliage was stabilized for analysis during the course of sulfur dioxide fumigations originating from a sour gas processing plant located in west-central Alberta. Controlled sulfur dioxide fumigations of seedlings were conducted in the laboratory to measure their effect upon ATP content. Field studies demonstrated that ATP concentrations of needle cells declined as sulfur dioxide concentration increased in the ambient air. An inverse linear relationship was found between ATP content and the measured sulfur dioxide concentration. The effect could be repeated in the laboratory with growth chamber cultured seedlings only in exceptional cases. It was repeated with detached branches from the field site exposed to sulfur dioxide under laboratory conditions. The results illustrate the fundamental differences between foliage preadapted to low-level sulfur dioxide fumigations and foliage grown under optimal conditions in a growth chamber.

Sour Gas

A 42km/356mm diameter pipeline was built and commissioned in 1962 and is the primary source of sour gas to a sour gas processing plant. The pipeline has operated as a dehydrated sour gas/condensate pipeline, and was assessed as a candidate for an Internal Corrosion Direct Assessment (ICDA). This analysis came with the challenge of a lack of operational and inspection history. The decision was made to obtain as much history as possible by interviewing previous operators, and to perform an ICDA analysis based on this information. The ICDA analysis was performed by a technical specialist utilizing 1) wet sour gas corrosion methodology and 2) ICDA (critical angle) technology. The analysis was performed for one ICDA region. Nine assessment cases were identified as the operating criteria changed with time and each was assessed. On occasion the gas specifications had criteria below the minimum levels of influence, and analysis was also performed with these adjusted to force identification of potential internal corrosion locations. The results were presented identifying two locations of potential long-term corrosion, and one location susceptible to corrosion post 2000. Following a review of the ICDA analysis, it was felt that there was sufficient confidence to proceed with the direct assessments. The decision was taken to expose the three identified locations. The direct assessment at all three locations was performed using guided wave UT as the initial anomaly detector, and phased array UT was then utilized to confirm any anomalies, and was run along the bottom of the exposed line to confirm no anomalies were missed. The results of the NDE indicated no anomalies of more than 10%, and it was concluded that no significant internal corrosion of concern exists. The final phase of the ICDA (post assessment) concluded that the analysis was successful and that the ICDA project was a success. The re assessment intervals will be driven by any future changes in the transported product, and information obtained from on line corrosion monitoring.

The Impact

The  presence  of  air  pollution  in  ambient  air  is  closely  related  to  the incidence  of  adverse reactions affecting human health. One of harmful pollutants and potentially major cause health problems is sulfur dioxide (SO 2 ). The number of vehicles that are passing and queuing on the crossroads  because  of  traffic light can  affect  the  concentration  of  SO 2 .  Besides,  in  these locations  there  are a lot of road users  which  are  potentially  exposed  by  contaminants, so information about the concentration of SO 2  is important to know. This study aimed to investigate the  impact  of  meteorological  factors  and  the  number  of vehicles  on  SO 2   concentrations. Impinger was used for air sampling, and pararosaniline method was used for determining SO 2  concentration. Sampling and calculation  of the number of passing vehicles were performed 3 times ie in the morning, afternoon and evening. Based on the results of the study, the highest concentrations of SO 2  were on the range of 15-21 mg/Nm3.

Rescue Time

Introduction. GOST R 12.3.047-2012 standard offers a methodology for determination of required fire resistance limits of engineering structures. This methodology is based on a comparison of values of the fire resistance limit and the equivalent fire duration. However, in practice incidents occur when, in absence of regulatory fire resistance requirements, a facility owner, who has relaxed the fire resistance requirements prescribed by GOST R 12.3.047–2012, is ready to accept its potential loss in fire for economic reasons. In this case, one can apply the probability of safe evacuation and rescue to compare distributions of fire resistance limits, on the one hand, and evacuation and rescue time, on the other hand.A methodology for the identification of required fire resistance limits. The probabilistic method for the identification of required fire resistance limits, published in work [1], was tested in this study. This method differs from the one specified in GOST R 12.3.047-2012. The method is based on a comparison of distributions of such random values, as the estimated time of evacuation or rescue in case of fire at a production facility and fire resistance limits for engineering structures.Calculations of required fire resistance limits. This article presents a case of application of the proposed method to the rescue of people using the results of full-scale experiments, involving a real pipe rack at a gas processing plant [2].Conclusions. The required fire resistance limits for pipe rack structures of a gas processing plant were identified. The calculations took account of the time needed to evacuate and rescue the personnel, as well as the pre-set reliability of structures, given that the personnel evacuation and rescue time in case of fire is identified in an experiment.

Hazardous Air Pollutants

: The NOx gasses (NO and NO2) are among the most important air pollutants, due to the toxicity of NO2, as well as the role of NOx in the tropospheric oxidation of Volatile Organic Carbons (VOCs), contributing to the formation of other hazardous air pollutants. Air pollution is one of the biggest health threats world-wide, hence reducing NOx levels is an important objective of the UN sustainable development goals, e.g. #3, “Good health and well-being” and #11 “Sustainable cities and communities”. Photocatalysis using TiO2 and light is a promising technique for removing NOx along with other pollutants, as demonstrated on laboratory scale. Furthermore, a long range of real-life test studies of varying scales have been conducted during the past two decades. The results of these studies have been conflicting, with some studies reporting no effect on the ambient air quality and others reporting significant reductions of NOx level. However, the studies are very difficult to compare and assess due to the very different approaches used, which consequently vary in quality. In this review, we aim to develop a set of objective evaluation criteria to assess the quality of the individual studies in order to simplify the interpretation and comparison of the existing studies. Moreover, we propose some guidelines for future test-studies. Furthermore, the approaches and main conclusions from 23 studies are independently assessed and discussed herein.

Pavel Kurochkin, manager of labor protection, industrial safety and ecology at NIPIGAS company, talks about the realization of the NIPIGAS project for the construction of the Amur gas processing plant for LLC Gazprom pererabotka Blagoveshchensk and about the design and implementation of preparatory works for the construction of the Amur gas-chemical plant for LLC SIBUR. New approaches to labor protection and safety, which are used at NIPIGAZ construction sites, make it possible to control the safety of work at heights and in inaccessible places and to monitor construction and installation works using video surveillance technologies and video analytics.
