Steam Heat Exchanger
Specification:
The steam-heat exchanger requires an adequate steam supply, which may require a steam generator depending on the rig’s steam supply.
Steam enters the vessel through an automatic control valve. Heat from the steam is transferred to the vessel’s internal tubing bundle and, in turn, the effluent passing through it. A choke between the effluent inlet and outlet enables preheating the effluent before and after pressure is reduced at the choke.
Technical parameters:
1) Working environment: Anti-sulfer EE or anti-acid 15%
2) Pressure level: 35MPa, 5072psi
3) Connection mode: 3"Fig 602 union
4) Coil pipe material: 20G(Heating coil pipe) Anti-sulfer EE, 20G+316L(Heating coil pipe) anti-acid 15%
5) Applicable codes: ASME VIII Div. 1, ANSI B31.3, API-6A(PSL-3), DNV2.7-1 skid and frame, H2S (NACE MR0175), DNV NPD,CE
Schematic diagram:
Features:
1) Automatic control valve for steam entry;
2) Internal tubing bundle for effluent traffic;
3) Steam trap with steam condensate outlet;
4) Safety relief valve;
5) Temperature controller;
6) Glass-wool insulation with aluminum jacket;
7) Choke between inlet and outlet to allow preheaing of effluent.
8) Increased safety by eliminating fire risk;
9) Improved efficiency through hydrate formation prevention, viscosity reduction, and emulsion breakdown.
Applications:
Surface well testing, production;
Conditions where regulations do not permit indirect-fired heaters.
