Condensate or, in conjunction with hydrocarbons, hydrates will from in the natural gas depending on the gas humidity. Hydrates and condensates cause problem on the natural gas refueling installation and vehicles.
ISO 15403: 2000(E) states (paragraph 5.1):
The single most important safety requirement of compressed natural gas (CNG) fuel us a very low water dew point temperature to preclude the formation liquid water at any time.
The skid mounted twin tower, external-heated, fully automatic, closed-loop regenerative dryer is used for the purpose of dehydration natural gas and provide dryer and oil free gas.
Havayar dual tower regenerative natural gas dryer is included the latest technology and safety features. It’s equipped with two desiccant filled Pressure Vessels, Electrical heater, Air cooled, Heat exchanger, Pre-after filters and can work with two working mode:
- AUTO DEW SWITCHING MODE
- FIXED TIME CYCLE SWITHING MODE
All dryers have been designed based on manufacture standard and in conformity with the latest edition of blew standard:
- ASME Sec. VIII for pressure vessel design
- ISA standard for instrumentation
- IEC & NFPA 70 standard for electrical components.
- API 661 standard for heat exchangers
- ASME B31.3 & B31.8 for piping
- GPSA for process
Havayar Dryer Features
Maximum EfficiencyLow running cost, low pressure drop and steady dew point are considered through careful design and manufacture.
Easy InstallationAll parts and sub equipment’s are completely assembled on the dryer bed and are shipped ready for installation with no assembly work required on the site.
Easy start up, operation and maintenance Completely automated control equipment which starts after pushing operation button, thereafter it can be controlled from a control panel, with all necessary interlocking devices provided to prevent trouble arise from operators or other disturbance. Routine inspection and maintenance are facilitated by optimum arrangement.
Minimum Pressure Drop The unique design of the regeneration system ensures the pressure stability during the heating and cooling regeneration processes.
