In the upstream sector, gum in condensate causes significant erosion in value worth millions of dollars per annum and increases operational cost due to high injection concentration of conventional antioxidants. Phenolic compounds are commonly used at low concentrations in the downstream sector to inhibit gum formation in refined petroleum products. However, gum inhibition in condensates, in the upstream sector, requires high concentrations of phenolic antioxidant. Therefore, there is need for cheaper and more effective antioxidants for gas condensates. The present study investigates the use of Red Onion Skin Extract (ROSE) as a natural inhibitor for gum formation in condensate based on ASTM D381. Treatments with ethanolic extracts of red onion skin were carried out on seven gas condensate samples with gum formation tendency.  At a dosage of 200ppm red onion skin extract caused a reduction of 17.4% to 99.6% in washed gum content of the condensate samples. The performance of ROSE was comparable to, and in some condensates better than, commercially available catechol. The result obtained using ROSE highlights the need to explore the commercial viability of this application in oil & gas upstream operations.

Vapor Absorption

The problem of losses of oil products from leaks during their storage and transportation at oil supply facilities is considered. The influence of oil product leaks on the environmental situation around oil depots and gas stations is shown. A detailed overview of existing methods and tools for detecting leaks of petroleum products from storage facilities is presented. The evaluation of their effectiveness. Two methods for detecting oil leaks and devices based on them are proposed. The first device monitors the movement of liquid in the tank, the second-detects petroleum products in wastewater. The problem of recovery of petroleum vapors and environmental pollution from the release of vapors of light fractions into the atmosphere is also considered. An overview of existing methods and means of recovery of petroleum vapors is presented. Two methods and devices for capturing oil vapors and returning them to the reservoir are proposed, based on different principles: vapor absorption in the cooled oil product and vapor recovery on the principle of the Carnot cycle. It is shown that these devices can provide effective detection of oil leaks and recovery of their vapors, as well as improve the effectiveness of environmental protection at modern gas stations and tank farms.

Irrigation Network

At the stage of water treatment for irrigation systems, the efficiency capture coarse and fine mechanical impurities, as well as oil products and organic compounds affects the reliability of the equipment of the irrigation network and the safety of energy exchange processes in irrigated agricultural landscapes. The violation of work irrigation system can cause disruptions in irrigation schedules of agricultural crops, crop shortages, degradation phenomena on the soil and ecological tension. For the combined irrigation system, a water treatment unit has been developed, representing a hydrocyclone apparatus with a pipe filter in the case. For the capacity of 250 m3/h the main geometrical dimensions of hydrocyclone have been calculated. To organize the capture petroleum products and organic compounds, it has been proposed a modernization of a hydrocyclone unit, consisting in dividing the cylindrical part of the apparatus into two section. The first is section is for input irrigation water, the second one is for additional drainage of clarified irrigation water after sorption purification by the filter, placed on the disk and installed coaxially with the drain pipe and the pipe filter.
