Weihai Puyi Marine Environmental Technology Co., Ltd.
In 2009, Puyi was founded in Weihai with 50 million USD investment
and area of 200,000 square meters, and took the lead in the
research and development of scrubber tower ( marine Exhaust Gas
Clean System) . Puyi currently has built three automatic production
bases for scrubber tower (EGCS) in Weihai, Nantong and
Zhangjiagang, respectively. It also has set up a marketing center
-Puyi(Shanghai) Environmental Technology Co., Ltd., in Shanghai,
one of the international financial and trade centers. It has
established a perfect after-sales service network in major shipping
countries and regions around the world.
After ten years of development, Puyi has ranked in NO.1 or top
position as follows:
--- the first marine scrubber (EGCS) manufacturer in the world.
-- the leading Asian Mg-based desulfurization inventor.
-- Puyi has become the only scrubber tower (marine Exhaust Gas Clean System) manufacturer with independent software copyright and the capacity
of independent production of Exhaust Gas Clean System control
systems.
-- the first batch of manufacturer who obtained compliance
certificate and IAPP certificate Japanese classification society in
China
-- the manufacturer who has got most orders for scrubber towers in
China.
Puyi has obtained orders for about 200 sets of Exhaust Gas Clean
System , 68 sets of which have been delivered and 50 sets of which
are in installation. Our customers are from the Chinese mainland,
Norway, Denmark, Italy, Turkey, UK, Cyprus, Greece, Japan,
Singapore, Thailand, Chinese Taiwan, Chinese Hong Kong and other
countries and regions. Our product quality is highly praised and
recognized by such customers.
Environment protection does not have the end. In the future, Puyi
will continue leading in the research, development and
manufacturing of ship environmental protection equipment.
Scrubber Tower
A marine exhaust gas cleaning system is such device that can remove
SQx from vessel’s engine and boiler exhaust gases with seawater or
NaOH solution or Mg(OH)2 solution to meet the IMO regulation on SOx
emission

Advantages |
Disadvantages |
Summary |
| Sea water (for open loop) | 1: Reliable technology and simple process for operation 2: Easily available sea water 3: Less equipment invest cost 4: No consumption of fresh water | 1: Larger scrubber required 2: Extra CO2 discharge 3: Not suitable for exhaut gas with high SOx 4: Large occupying space and low desulfurization efficiency in low
salty sea water 5:Depending on the sea water alkalinity 6: Produced more effluent | 1: Simple structure and cheap cost 2: Applicable to the sea where discharge effluent can be allowed |
Fresh water +NaOH (close loop or Hybrid) Hybrid- can be realized by one touch control beteen open loop and
close loop | 1: Not relying on the condition of sea water 2: High desulfurization efficiency 3: Less CO2
| 1: Consuming fresh water 2: Requiring dosing system 3: Requiring cooling system 4: NaOH is required to be stored safely | 1:High equipment cost 2: Better stability |
Sea water + Mg(OH)2 (close loop or Hybrid) Hybrid- can be realized by one touch control beteen open loop and
close loop
| 1: Not relying on the condition of sea water 2: Better desulfurization efficiency than sea water 3: Less alkaline required 4: Can be easily and safely stored and transforted | 1: Requiring dosing system 2: Requiring cooling system
| 1: High equipment cost 2: Better stability 3: Harmless to the body |
