Stationary gas treatment plants
Integrated gas treatment unit (CGTP) is a system of process equipment and various auxiliary devices that provides collection and treatment of associated petroleum or natural gas and gas condensate in accordance with the requirements of STO Gazprom 089-2010 (for further transportation), GOST 5542-2014 (for use as fuel), as well as in accordance with the requirements of industry (OST) and state (GOST) standards.
Integrated gas treatment unit (IGTU) is designed for purification, regulation, distribution, measurement and preparation of associated petroleum or natural gas to the specified parameters, which are to be used in oil and gas producing enterprises, as well as in petrochemical and chemical industries.
The equipment of Integrated gas treatment unit (IGTU) the GTU allows to carry out the following tasks:
- gas treatment to the parameters specified by the requirements of the technical specifications;
- gas treatment to a given gas dew point;
- gas treatment to a predetermined dew point;
- supply of gas with specified pressures and temperatures to the main pipelines;
- gas preparation for own needs;
- gas purification from condensate;
- gas purification from hydrogen sulfide;
- gas separation and purification using hydrate inhibitors;
- preparation of gas condensate.
The unit is mounted on an open site or can be a complete prefabricated unit, tested and adjusted to operating parameters. The composition and execution of each specific installation is determined based on the requirements of the Customer.
Advantages
- unit-modular design and maximum factory readiness allow the installation of equipment in a short time
- Can be developed individually according to customer requirements
- All calculations are made in specialized licensed software systems
- Ease and flexibility of process control
- Own production of flare and heating equipment, air coolers
- Possibility of designing and manufacturing gas treatment plants with the required capacity
The units are designed for operation in climatic zones with air temperature from minus 60°С to plus 45°С.
GTU equipment is developed for various methods of product preparation:
- gas treatment plants by filtration/separation;
- installations for gas treatment by the method of low-temperature separation;
- gas treatment plants by low-temperature condensation;
- gas treatment plants by absorption drying;
- gas treatment plants for adsorption drying;
- modernized gas treatment plant.
