Vapor Emission Control System

Introduction
• Minimizing the emissions of VOCS (Volatile Organic Compounds) from oil tankers during the fluctuating ambient conditions experienced during voyages is important from both environmental and commercial points of view.
• The controlled release is often undertaken when the gas pressure approaches a pre-set point. However, it is not always clear at what pressure a manually controlled release should be stopped. Without this information, excess vapor can be released, causing air pollution and a loss of gas.
• To meet this challenge, a VECS and Reporting System can be used to control the vapor pressure in oil cargo tanks to minimize and fully control VOC emissions. It is designed to comply with the latest international rules and regulations with an advanced reporting system.
• The VECS is installed on the mast riser’s bypass line, and controls the vapor pressure in all the cargo tanks during voyage for direct emission control in order to reduce VOC loss from the tanks during voyage.
• By controlling the pressure in the venting system, it is possible to fully control the VOC emissions.
• The VECS can be programmed to enable adjustment of the opening setting on the valve according optimal level for the specific cargo.

Model : EVDE

There is little technical difference between EVDD and EVDE model.

But EVDE was tested according to the international standard IACS UR M82 was newly established in March 2023 and is applicable to engines or ships contracted from July 1, 2024.

It is a special one for applicable Ship’s Engine and was firstly tested and approved by this rule.

We are currently approved by DNV and KR classification societies, and ABS, BV, LR, etc. are waiting for classification review after application by the end of this year.

Also as IACS UR M82 4.3.5, the shield of this can be selected to option.

So EVDE was tested with 2 option with shield or without shield and also successfully passed the test.

Therefore, if the engine or vessel should be applied with IACS UR M82, we recommend you the select EVDE model.

Air Release Valve

Introduction
While the system is flowing under pressure, air release valves continually and automatically exhaust the small quantities of air that would otherwise be collected at system high points. This ensures the system remain free of trapped air (and sewage gases) thereby increasing system efficiency and reducing pumping costs.

Benefits
• Pressure relief function (exceeding atmospheric pressure)
• Liquid overflow protection
• Relief of small air pockets from pipeline
• Increase of pump efficiency
• Less system energy
• Maintenance free

Air Release & Vacuum Valve

Introduction
There is two critical time in the operation of a pipeline. During filling, air occupied in the empty pipe must be evacuated ahead of the incoming liquid in a controlled and efficient manner so that surge and water hammer can be minimized and liquid can completely be filled in the pipe. During draining, whether planned or unexpected, air must be admitted into the system to replace the out flowing liquid to avoid excessive vacuum and possible pipeline damage. Air release valve are designed to release accumulated air pockets from the system, while pipelines are pressurized. Air pockets cause increase of energy consumption because pumping operation will be at higher water heads to overcome pressured air. Air release valves have function to protect high shock and surge pressure, water hammer and liquid overflow from fresh or sea water pipelines. PROSAVE Valve can assure to provide low maintenance cost of pipelines and pump systems.

Benefits
• Pressure & Vacuum relief function
• Surge and water hammer prevention
• Liquid overflow protection
• Providing high capacity venting for pipeline protection
• Increase of pump efficiency
• Less system energy
• Maintenance free

Combination Air Valve

Introduction
Combination Air Valves are normally installed at high points of pipelines where air would naturally is arisen ahead of the incoming liquid during filling and collect air during operation and/or where negative pressure occurs during draining. The large (air release & vacuum breaker) and the small (air release) orifices are both opened during filling, and the majority of the air passes through the large orifice. The rate of air discharge is a function of the differential pressure across the air release & vacuum breaker valve. During filling, incoming water compresses the air in the empty pipe until the pressure differential across the air valve is sufficient, so that air is discharged at the same volumetric rate as water is entering the pipe.
After all the air has been purged, liquid enters the valve, lifts the float ball and closes both orifices. While the large orifice is closed, the small orifice is reopened as necessary to release any air that collected in the valve after it has closed. In case that the internal pressure falls below atmospheric pressure, both orifices are opened to allow air to flow through the valve into the system at the same volumetric rate at which the liquid is draining thus avoiding critical vacuum and damage to the pipe.

Benefits
• Pressure & Vacuum relief funciton
• Surge and water hammer prevention
• Liquid overflow protection
• Providing high capacity venting for pipeline protection
• Increase of pump efficiency
• Less system energy
• Maintenance free
• Release of small air pockets under operation pressure

Vacuum Breaker with Air Release Valve

Introduction
The VB-AR(L) model is a combination of KSVB and AR(L). When negative pressure occurs in the piping system, air flows into the valve from the outside by KSVB, and when the inside of the piping is filled, a small air pocket is discharged to the outside of the valve through AR(L).

Benefits
• Protection of piping systems from positive pressure or vacuum overpressure
• Avoid evaporative loss of product
• Discharge of small air pockets in piping system
