English term or phrase: coalescing
• Standard material Stainless steel ASTM A 182 GRF 316(L) with higher grade alloys as option
• Maximum Flow Rate:
Sizing in accordance with API614, API 692 or alternatively based on maximum filter media drain layer velocity
Design Features
• Coalescing/particle or particle only filtration element options
• Interlinked transfer valves with bolted construction and providing a safe and zero-leak operation both to atmosphere and isolating the pressure vessels
• Both transfer valve (class A) and needle valve (class B) compliant to ISO 15848 (fugitive emission)
• Bolted cover construction allowing an easy and clean filter element change out
• Integrated equalizing line and standardized, modular needle valve simplifying tubing and flange requirements
Performance Characteristics
Pressure-drop
The pressure-drop in a filter system is the pressure difference before and after the filter system.
Pressure-drop occurs due to transfer valves, pipe bends, filter media selection and the loading of the filter element.
Pressure drop curves in seal gas coalescing application show three stages:
1.
Start-up (clean) pressure-drop
When a new filter element is installed, the element is clean and dry, the filter media pores are not blocked with particles or liquid droplets, and gas flows freely; most of the pressure-drop is caused by the filter system.
The start-up pressure-drop (clean and dry filter element) of the total system is described in the API 692 as filter sizing parameter.
2.
Operational (saturated) pressure-drop
The filter element is capturing/**coalescing** and draining liquids from the gas flow.
The filter element pores are partially blocked with captured droplets (saturated) and the gas has more restrictions when passing through.
The operational pressure-drop when fully saturated can be 4 times higher than start-up.

Фильтры-коалесцеры широко применяются в установках систем очистки природного, транспортируемого, попутного нефтяного газов, в установках систем очистки топливного, импульсного и буферного газов, а также в установках систем очистки сжатого воздуха и других технических газов.

Фильтры-коалесцеры предназначены для тонкой очистки жидких и газообразных сред от механических частиц и капельной жидкости. В корпус фильтра-коалесцера устанавливаются нерегенерируемые, сменные фильтрующие элементы (картриджи) коалесцирующего типа.

В фильтрах-коалесцерах очистка среды от жидких примесей происходит благодаря способности фильтрующего элемента коалесцировать (объединять) жидкие аэрозольные частички мельчайшего диаметра от 0,3 мкм в более крупные с последующим накоплением и удалением жидкости через дренажную систему фильтра.
