On-Site Gas Treatment Units
Integrated Gas Treatment Unit (IGTU) is a system of process equipment and various auxiliary devices that collects and treats associated petroleum or natural gas and gas condensate in accordance with the requirements of STO Gazprom 089-2010 (for further transportation) and GOST 5542-2014 (for use as fuel), as well as in compliance with requirements of industry (OST) and state (GOST) standards.
Integrated Gas Treatment Unit (IGTU) is designed for purification, regulation, distribution, measurement and treatment of associated petroleum or natural gas to the specified parameters, which shall be used in oil and gas producing enterprises, as well as at petrochemical and chemical production facilities.
IGTU equipment allows to implement the following tasks:
- gas treatment to parameters set by the requirements of technical specifications;
- gas treatment to a given gas dew point;
- gas treatment to a given hydrocarbons dew point;
- supply of gas with given pressures and temperatures to the main pipelines;
- gas treatment for own needs;
- purification of gas from condensate;
- purification of gas from hydrogen sulfide;
- gas separation and purification using hydrate inhibitors;
- gas condensate treatment.
Unit is installed outdoors or can be made as fully prefabricate block-modular device, tested and adjusted to operating parameters. Scope and design of each specific unit is determined based on Client’s requirements.
Advantages
- Block-modular design and maximum level of prefabrication allow to install equipment in a short time
- Can be developed individually according to Client’s requirements
- All calculations are made in specialized licensed software systems
- Easy and flexible process control
- Own production of flare and heating equipment, air coolers
- Possibility of designing and manufacturing Gas Treatment Units with required capacity
Units are designed for operation in climatic zones with air temperature from minus 60°С to plus 45°С.
IGTU equipment is developed for various methods of product preparation:
- gas treatment units using filtration/separation method;
- gas treatment units using low-temperature separation method;
- gas treatment units using low-temperature condensation method;
- gas treatment units using absorption drying method;
- gas treatment units by adsorption drying;
- modernized gas treatment unit.
