Amine regeneration unit

Here the amines are being “unloaded” from the unwanted sulphur components they are carrying. After this process the “lean” amine is sent back to train 1 and 2 in the gas sweeteners. The amines are continuously recycled.

Apartment building for citizens of Rozhkovo

The village of Rozhkovo, with a population of approximately 300 residents, was formerly situated within the exploration zone of the Chinarevskoye Field. In order to successfully pursue its drilling and exploration activities in the licence area and to carry out activities in compliance with environmental law, Nostrum Oil & Gas needed to relocate the residents of the village of Rozhkovo to new housing. 

After a series of consultations with the residents of Rozhkovo in 2006, the residents of the village unanimously approved the terms of the relocation programme (the “Resettlement Action Plan”). Nostrum Oil & Gas also obtained permission from the administrative body of western Kazakhstan in December 2006 regarding the relocation programme. In addition to complying with all applicable legislation, Nostrum Oil & Gas obtained additional expert advice so as to conduct the resettlement according to standards for such activities established by the EBRD.

The resettlement plan was finalised in July 2009. Most families relocated to an apartment building in Uralsk that the company constructed, while other families relocated to other housing. Demolition of the village and restoration of the land in its initial condition in an environmentally responsible way is ongoing. The relocation committee of Nostrum Oil & Gas continues to assist residents with post-relocation needs on an individual basis.

Compressor C101 and C103

Compressors are used at different positions in the GTF. They are needed because certain processes require different pressures in consecutive stages. The high capacity compressors are directly driven by gas engines using gas produced on site. 1. Inlet Compressors The inlet compressor C101 boosts associated gas pressure to desired level (64 bar) for complex processing and gas cleaning. The inlet compressors C103 & C104 boosts gas pressure from gas and condensate wells to desired level (64 bar) for complex processing and gas cleaning 2. Compressor C105 The stabilizer overhead compressor C105 boosts gas pressure after stabilization to 40 bar at the inlet of compressors C103 & C104. 3. Compressors C1131 & C2131 The overhead compressors C1131 & C2131 boosts gas pressure after outlet from complex cleaning to desired level for further transportation and sale.

Flare stack

The Gas Treatment Facility (GTF) also has a gas flare stack to protect the pipes and groups from the GTF from over-pressuring de to unplanned upsets. As such this flare is nothing else than a safety device. It can be compared with the spout on a tea kettle when it starts whistling as the water starts boiling. In case of overpressure in the GTF, the pressure is automatically routed through pipes to the flare stack where it is burned. This is only done exceptionally in case of emergency to avoid damages to the GTF and its employees.

Incinerator

In the incinerator all residual fractions are combusted using high temperature. Incineration of waste materials converts the waste into ashes, flue gases and heat that is used to generate electric power. The flue gases are cleaned of pollutants before they are dispersed in the atmosphere.

LPG tankfarm

The Gas Treatment Facility has 18 LPG-tanks with a capacity of 250 cubic meters each. The LPG tankfarm includes fire fighting infrastructure, control pannels, pumps, etc.

Main pipe rack

The main pipe rack is the central transportation system of the Gas Treatment Facility (GTF). Through the pipes all liquids and gases are transported to and from the different processes.

Nostrum Oil & Gas welcomes President of Kazakhstan

In June 2009, Nostrum Oil & Gas had the honour of welcoming His Excellency Nursultan Nazarbayev, President of Kazakhstan for the official opening of its rail terminal. The President was impressed with the Company’s commitment to invest in the infrastructure needed to develop the Chinarevskoye Field further. In the picture below, the then General Director of Zhaikmunai LLP is talking with His Excellency Nursultan Nazarbayev.

Rail terminal

Nostrum Oil & Gas has a railway terminal nearby the city of Rostoshi where the oil from the Chinarevskoye field is loaded.

The pipeline and loading terminal were successfully completed in 2008 and have been fully operational since January 2009. The oil pipeline has a maximum annual throughput capacity of 3 million tonnes. The rail-loading terminal receives all crude oil and condensate produced by Nostrum Oil & Gas and has a capacity of approximately 4 million tonnes of crude oil and condensate per year.

By transporting oil production by rail, Nostrum Oil & Gas does not encounter any dilution of the quality of its crude oil as it would if it was transported by pipeline and mixed with oil from other sources, and is therefore able to obtain a higher price for its production in the export market.

Slug catcher

Here the associated gas coming from the Oil Treatment Unit (OTU) together with the condensate & gas from the condensate wells enters the Gas Treatment Facility (GTF) and gaseous fractions are separated from the liquid fractions. Under the influence of gravity liquids will tend to settle on the bottom, while the gasses occupy the top section of the vessel.

Stabilization

In this part of the Gas Treatment Facility (GTF) the liquid fractions (the condensate) will be further stabilized: i.e. gaseous hydrocarbons evaporating from the liquid fractions are separated.

Train 1

The GTF has two identical “trains” (i.e. processing lines) where a group of processes are combined to remove acids, dehydrate the gas and separate the fluids into sweet and dry natural gas, LPG and stable condensate (liquid). Stable condensate has a higher value than crude or natural gas. To remove the acids from the gas (this is to “sweeten” the gas) amines are used. They are chemical components that remove acid sulphur components from the gases and they can be recycled in the amine regeneration unit.
