Pulp & Paper
Heat exchangers for pulp and paper mills: black liquor, condensate and process heat recovery equipment.
What This Sector
Demands
Dolphin Group is an ADNOC-approved, Local+ Certified manufacturer of ASME U2 Section VIII Div.1 and TEMA Class C evaporator heaters, condensate coolers and heat recovery exchangers for fibrous, scaling media. Operating from its Mussafah, Abu Dhabi facility for over 40 years, it delivers stainless and duplex-construction equipment to pulp and paper mills worldwide.
Fibrous fouling
Fibre and scale plug conventional exchangers; wide-gap and free-flow geometries keep mills running. A standard tube-gap exchanger dropped into this service will plug and lose duty far faster than one engineered for fibrous media.
Corrosive liquor service
Black and green liquor circuits demand stainless and duplex construction with qualified welds. Carbon steel equipment in this service corrodes quickly and shortens the interval between refurbishments.
Energy economy
Steam economy defines mill margins — recovered heat is the cheapest energy a mill can buy. An evaporator heater running below its steam economy target quietly erodes margin on every tonne produced.

Why Operators Choose
Dolphin Group
ADNOC-approved, Local+ Certified
Qualified to the procurement standards ADNOC group companies require, with in-country value that scores directly on mill operator tenders.
Wide-gap geometry for fibrous, scaling media
Free-flow and wide-gap exchanger geometries are engineered at Mussafah specifically to resist fibre and scale plugging that stops conventional exchangers.
40+ years of corrosive-liquor fabrication experience
Four decades of stainless and duplex construction with qualified welds inform every evaporator heater and cooler we build for black and green liquor service.
Frequently Asked Questions
Yes. We design and fabricate to ASME U2 Section VIII Div.1 alongside TEMA Class C for evaporator heaters, condensate coolers and heat recovery exchangers.
Yes. Wide-gap and free-flow geometries are engineered specifically to keep mills running against fibre and scale plugging.
Stainless and duplex construction with qualified welds are standard for corrosive liquor service.
Yes. An evaporator heater bundle was refurbished and returned to steam economy targets within a planned outage.
Yes. Heat recovery exchangers are engineered to recover steam economy, since recovered heat is the cheapest energy a mill can buy.
Yes. Chemical cleaning services restore performance on fibrous and scaling equipment without attacking the underlying metallurgy.
Yes. Dolphin Group is ADNOC-approved and Local+ Certified — one of roughly 70 Local+ Certified companies in the UAE.
