The following contains details of PANASIA’s eco-friendly energy systems designed to protect the air and water environments.

International Maritime Organization (IMO) has set the maximum allowable content of sulfur in fuel used by ships through MARPOL 73/78 ‘International Convention for the Prevention of Pollution from Ships’ that entered into force in 2005. All ships operating in Sulfur Emission Control Areas (SECA) have been required to use fuel with a sulfur content of 1% or less since July 2010 and to use fuel with the sulfur content of 0.1% or less since 2015.

In addition, the regulatory requirement of using fuels with a sulfur content of 0.5% or less in all oceans throughout the world is to take effect in 2020. To meet the requirements on the permitted sulfur levels in ship fuel, ships must use fuel with low sulfur content or be equipped with a desulfurization system that meets IMO, MARPOL 73/78 regulations.

Low-sulfur fuel is a viable option on a short term basis but is too expensive to use which makes the fuel gas desulfurization system combined with a continued use of existing high sulfur fuels an optimal alternative in terms of long-term operating costs while meeting environmental regulations.

Emission Control Areas

Emission Control Area. Emission Control Areas (ECAs), or Sulfur Emission Control Areas (SECAs), are sea areas in which stricter controls were established to minimize airborne emissions from ships as defined by Annex VI of the 1997 MARPOL Protocol

Area Sulphur Limit Scrubbers
Global 0.50% (2020) Local restrictions may apply for Open-loop scrubbers
SECA 0.10% Yes
EU 0.10% in all ports Open-loop scrubbers restricted In some countries
China 0.50% in national Waters (12 nm) Certain restrictions apply for Open-loop scrubbers
California 0.10% within 24 nm No, only with research exemption

SOx emission control areas reported to IMO are the North Sea, the Baltics and the North American seas. In addition, IMO adopted Res. MEPC. 202 (62) and the U.S. Caribbean region has been additionally designated as NOx and SOx emission control areas. Moreover, as a measure to control smog within China, the Chinese government has designated Yangzi River (Shanghai), Pearl River (Hong Kong, Macao) and Bohai Bay as the emission control areas, and intend to expand regulation in stages.

Products
U-Type
1-80MW

The foot print in the U–Type Scrubber is wider in width and shorter in height than that in I-Type.
In the U–Type Scrubber System, each exhaust gas discharge medium (ex. main engine, aux. engine and boiler) has its own bypass line, and dry mode is not applicable.
Packing is used in the inside of the Scrubber.

The foot print in the I–Type Scrubber is narrower in width and higher in height than that in the U-Type. In the I–Type Scrubber System, Dry mode is available and a bypass valve is not applied. Packing is not used in the inside of Scrubber. I-Type is recommended when there is not enough space for a bypass line in the funnel and the difference in the total gas exhaust flow of the combustion engine is not significant.

We provide solutions optimized for the characteristics of different ships, from small-sized to large-sized. We also offer square scrubbers that can keep cargo loss to a minimum for certain vessel types.

1-6MW

PANASIA’s Scrubber PaSOx™ V.MCR offers a range of solutions that fit installation spaces on board limited to small-sized desulfurization systems (1 to 6MW), which have been optimized for small- or medium-sized ships. It will be the ideal solution that can efficiently respond to the sulfur dioxide regulations.

System Diagram

PANASIA PaSOx™ Exhaust Gas Cleaning System removes sulfur oxides in the marine environment. It is largely classified into the Open Mode, Close Mode, and Hybrid Mode. In Open Mode, seawater is used as wash water. In Close Mode, an alkaline solution is used as wash water. In Hybrid Mode, you can switch between Open Mode and Close Mode.

Open Mode System

In Open Mode, seawater is used as wash water.
This exhaust gas cleaning process utilizes the ability of seawater to remove sulfur dioxide naturally.
In the Open Mode System, seawater is supplied through seawater pipes.
The wash water from the scrubber is discharged to the sea.
The quality of such discharged water is monitored through the wash water monitoring system.
Exhaust gas discharged following treatment in the scrubber is monitored by a gas monitoring system in real time.

Close Mode System

In Close Mode, the system circulates wash water in the wash water tank.
Wash water is supplied to the scrubber at a constant temperature by the wash water pump through the cooler. The used wash water from the scrubber is collected back into the wash water tank and reused. The system monitors the pH level of wash water to automatically control and supply alkaline (NaOH) dosing to remove sulfur oxides.
During the reuse process, wash water is cleaned through the Wash Water Cleaning System.
The wash water cleaned through the Wash Water Cleaning Unit is either re-supplied to the wash water tank, discharged, or stored in the holding tank (discharge restricted area).
Sludge is generated in the water purification process of the wash water cleaning unit, and it is stored in the sludge tank. During the scrubber cleaning process, temperature rise of the wash water is managed by the cooler.

Research & Test Apparatus (Scrubber Test Facility)

PANASIA developed a hybrid of the I Type and U Type scrubbers for its own barge vessel to achieve optimal design and performance. Using HFO and seawater, the company ran tests under conditions that were most similar to the operating conditions of the scrubber actually onboard. We continuously work hard to improve the performance of our products.
