At present, the compressor industry of the oil sector of Azerbaijan is one of its leading links. If by the end of the 20th century the number of wells using the gas-lift method of production was about 42-46%, then by the end of 2019 it exceeded the 50% level. Compressors are an integral part of this technological process and require a strict improvement in the technical level of their safe operation. Therefore, improving the technical and economic performance of the compressor unit is an important task. This work is devoted to the study of design features and the main causes of valve failures in reciprocating compressors, as well as an assessment of their safe operation. Keywords: reciprocating compressor, reliability, valve, safety, gas-lift extraction method.

Compressor Reliability

A 38 MMSCF/D Cooper Bessemer Model LM-9 reciprocating compressor in hydrogen service at the Praxair Westlake LA facility has experienced notable particulate contamination within the feed gas. The particulates were believed to be caused by upstream piping corrosion; however, to definitely state the cause, the properties of the fluid existing in the five-stage compressor needed to be more fully understood. An OLI electrochemical simulation software was used for dew point prediction, determination of the condensed phase ionic equilibria, and corrosion rate prediction. These tasks were beyond capabilities of the site-licensed UniSim software, as presently configured. Specifically, the model was used to identify the dew point conditions (temperature, pressure) and properties of the condensed water (pH, corrosivity, dissolved O2, and chlorine speciation). Model results were compared with site inspection findings. Subsequently, recommended limits for chlorine and oxygen in the feed gas were established to improve long term compressor reliability.

Fault Feature Extraction

This paper presents a feature extraction method based on LMD and MSE for reciprocating compressor according to the strong nonstationarity, nonlinearity and features coupling characteristics of vibration signal. The vibration signal was decomposed into a set of PFs, and then multiscale entropy of the first several PFs were calculated as feature vectors with different scale factors. Based on the maximum of average Euclidean distances, the feature vectors which have the best divisibility were selected. The feature vectors of reciprocating compressor at different bearing clearance states were extracted using this method, and superiority of this method is verified by comparing with the results of sample entropy.

The Impact

Oil-rich countries often face negative consequences of natural resources-led development on their overall economic performance. One of the reasons is that a country’s rising extraction rates frequently lead to various changes in its public policy and revenue management. Colombia has spectacularly increased its oil production by almost 500,000 barrels per day (bpd) in ten years, which was the effect principally of the implementation of strongly market-oriented petroleum policies in 2003. It is now the fourth largest crude producer in Latin America, registering nearly ten times more export sales than at the end of the 20th century. The economic effects of the oil-boom are already visible, which has created many new challenges the government must face in order to ensure sustainable development in the country, and to be able to mitigate the impact of the recently dropping world oil prices. The purpose of the article is to present the latest findings on the impact of the oil sector development on the Colombian economy in the 21st century, focusing especially on the current situation.

Donor Interest

Donor interest in the natural resources extractives sector is based upon the premise that it represents an opportunity to improve a country’s development prospects. However, in many cases the presence of extractive resources is associated with poor economic performance. As a result, some donors are trying a radically different approach. This chapter explores one such programme funded by the UK Department for International Development: the Facility for Oil Sector Transparency and Reform in Nigeria. The chapter outlines five lessons learned from this example. First, continual analysis is essential to understand the underlying incentives of key actors. Second, interventions need to be locally led in order to provide legitimacy for reform. Third, interventions need to be flexible and adaptive. Fourth, acceptance of an element of risk is necessary. Fifth, donors need to develop a new way of measuring impact.

Gas Lift

Tightness, as well as the reliability of the valve plate, is a complex property of the effective operation of compressor cylinders of the first stage and, in general, gas-engine reciprocating compressors. The issue of valve plate tightness is a subject of independent study, since technical and economic efficiency depends on their work. In this connection, only some data obtained under operating conditions are presented in this work. As a research result, it is found that, taking into account the identified requirements for the gas lift system, in order to effectively increase the operating hours of valves with increased tightness of the plate, it is necessary to check and purge the valves. Therefore, each valve in the gas lift compressor station, without subjecting them to cleaning, is first recommended to check for leaks. To confirm the feasibility of checking valve tightness, special equipment is offered for each gas-lift compressor station, a purge chamber, on which the tightness of valve plates is checked. The usefulness and importance of the purge chamber is in preparation of the valve at the gas lift compressor station, which contributes to increased efficiency, safe operation, normal tightness and reliability of its operation.

Design And Construction

This article describes some of the safety considerations for the design and construction of micro/nano facilities and applicable building code provisions. The two key elements required for safe operation in micro and nanotechnology facilities are: (1) engineered features incorporated into building construction, and (2) administrative features that deal with how people work within the facility.
