Gas separators (GS)
Gas separators are used to remove solids, liquid hydrocarbons, liquid drops, suspended and other particles from natural and petroleum gas. This equipment is a crucial element of process trains at natural gas production, treatment and storage facilities. It is used by enterprises in oil & gas, chemical and processing industries.
Structure and operating principle
A gas separator can be used either as an autonomous piece of equipment or as one of the units within the whole complex.
It is customary to classify gas separators in accordance with their structural peculiarities. As per this classification, gas separators manufactured by the Joint-Stock Company ModulNefteGazEngineering can be horizontal and vertical. The main difference between these devices is in the way of installation.
Regardless of the classification, gas separators consist of a horizontal or a vertical shell with elliptical heads and internals. Lug supports or legs can be used to install gas separators to the design position.
The structure of gas separators also includes manholes, process and auxiliary nozzles. Such structural peculiarities are necessary to ensure access inside equipment, inlet/outlet of gas, withdrawal of condensate, installation of instruments, block and safety valves and other equipment. Gas separators can be additionally equipped with a system of liquid or steam tracing ensuring maintenance of the operating temperature.
The type, structural peculiarities and composition of the equipment depend on the following factors:
- Amount of inlet gas;
- Properties and composition of gas at the inlet;
- Requirements for the gas parameters at the outlet.
One of the kinds of gas separators is a centrifugal gas separator. The operating principle of such separator is based on the action of the centrifugal force, under the action of which liquid drops and solids are separated from gas.
Technical characteristics
When selecting a gas separator, it is important to pay attention to the technical characteristics of these devices:
- Volume;
- Pressure;
- Capacity;
- Degree of purification.
JSC MNGE offers low pressure (less than 0.6 MPa), medium pressure (0.6 to 2.5 MPa) and high pressure (over 2.5 MPa) models. Our gas separators also differ in the applied purification technology. Solids, hydrocarbon condensate and other particles are removed using gravity, inertia, centrifugal or combined technology.
Advantages of placing an order for a gas separator with JSC MNGE
Gas separators manufactured by the Joint-Stock Company ModulNefteGazEngineering are distinguished by a high degree of gas separation due to the use of special packings. Our products are also distinguished by a high level of capacity and a possibility of operation in case of a slug flow or a normal gas flow. The specialists of JSC MNGE are ready to design and manufacture gas separators taking into account individual requirements of the Client. One more advantage of our company is a favorable price for gas separators, since we are a manufacturer of this kind of equipment. You can order the required model of a gas separator on the website of JSC MNGE or by phone + 7 (347) 216-10-01 (ext. 104).
