Uzbekistan SEG 1 TPY Zeolite Gas Purification Unit DCS + IODS Engineering Project

Overview

Shurtan Gas Condensate Field: A Pillar of Uzbekistan's Energy Security

• 15.25 Million USD Total Investment for the Project

• 20 Billion Cubic Meters of Natural Gas Annually Processed

• 4 Billion Cubic Meters of Desulfurized Gas Purified Each Year

The Shurtan Gas Condensate Field, one of the largest natural gas fields in Uzbekistan, is situated in the Guzar District of the Kashkadarya Region and is developed by Uzbekneftegaz. Since its industrial commissioning in 1980, this field has played a crucial role in ensuring Uzbekistan's energy security by supplying domestic power generation, city gas, and petrochemical feedstock.

The zeolite gas purification unit at Shurtan's headquarters comprises 5 modules. Here, cleaned and dried natural gas is transported to a propane-butane mixture plant, while regeneration gas is recirculated back to the amine-based purification unit. Operational from 1985 to 1997, this aging equipment now necessitates modernization. Uzbekneftegaz is advancing the project with a total investment of 15.25 Million USD aimed at upgrading zeolite purification technology to process an annual volume of 20 billion cubic meters of natural gas for desulfurization, dehydration, and impurity removal. Additionally, it plans to purify another 4 billion cubic meters of desulfurized gas each year.

Solution

Ensuring Intelligent and Stable Operations

HollySys has provided the project with a Distributed Control System (DCS) cabinet featuring 260 I/Os, along with a power distribution cabinet, effectively addressing the intelligent requirements of purification modules and regeneration units. Commissioned in January 2024, the system's stability and intelligence have received high praise.

Results

Enhancing Gas Quality and Supporting Sustainable Development

This project enhances gas quality to comply with international standards, extends equipment lifespan, reduces maintenance costs, and bolsters Uzbekistan's energy economy by optimizing gas processing for both export and domestic consumption. Additionally, it promotes technical collaboration by integrating global expertise with local manufacturing capabilities. The modernization significantly elevates purification capacity and gas quality, thereby reinforcing Uzbekistan’s energy supply system.
