The storage and loading of petrochemical products leads to the generation of hazardous vapours. These vapours are harmful to the environment and mankind. In the past, these vapours have been released into the atmosphere in an uncontrolled way, resulting in atmospheric pollution and product losses.
Emissions that occur during the loading, discharging and storage of organic liquids are called Volatile Organic Compounds (VOC). VOC emissions contribute to the formation of photochemical oxidants such as ozone, which in high concentrations, can impair human health and damage vegetation and materials.
Some of the VOC emissions from petrol are classified as toxic, carcinogenic or teratogenic. These emissions represent a significant contribution to air pollution especially in urban areas. Throughout the world legislative bodies are increasingly focusing on the detrimental effect of these VOC emissions.
The Vapour Processing System (VPS) is designed to avoid these emissions. At the same time the VPS contributes to the sustainable development of bulk-handling companies by reducing their electricity consumption.
How does the VPS work
The VPS consists of a modified gas engine with a continuous dual fuel device and is controlled by a specially designed engine, generator and fuel management system.
The VPS operates as a fully automatic device. As soon as any hazardous vapour is detected the system starts operating.
The fuel management system will constantly monitor and adjust all settings within the system to ensure an efficient and effective operation. When the system does not detect any vapour it will shut down automatically. The collected vapour is converted into electricity by the gas engine and generator.
The recovery of the engine heat can be used for heating storage tanks as well as buildings at the terminal. The VOC reduction exceeds up to 99,9% with and energy recovery efficiency of 31% for electricity production up to 76% (when heat recovery is included).
The prime advantage of the VPS is the generating of electricity during the process instead of consuming it. The produced electricity can be used by the terminal to reduce purchase from the grid.
An average 50% to 75% of the yearly electricity consumption at the terminal can be produced by VPS. Additionally any surplus production of electricity from the VPS can be sold to the grid. In this way real savings can be established that will positively contribute to the sustainable and society responsible enterprising of your company
The Vapour Processing System
 
Environmental performance
 The VPS meets the worlds most stringent environmental legislation:
  • German TA-Luft
  • NER (Dutch Emission Guidelines)
  • EU Directive 94/63/EC.
Due to the fully controlled combustion process, all VOCs in hazardous petrochemical vapours are processed. The VPS complies with the German TA-Luft standard, which is considered as the strictest norm in the world. The production of electricity out of harmful emissions, combined with an enormous reduction on the traditional energy consumption, assists you in creating a sustainable operation. 
Economics 
The VPS is designed to minimize operational costs. Because the system is fully automatic and remote controlled, no operating personnel is required. The VPS mainly consists of standardized components, such as its engine and generator. Maintenance is done by local mechanics. By far the most significant aspect however is the positive energy balance attained by the process as the VPS generates electricity. A return on excise duty can be granted by the authorities when processing taxed gasoline vapours.
Flexibility
The VPS is very flexible in its operations. More than 80 different product vapours can be converted into electricity simultaneously. We offer one universal system to tackle many problems. By using different application sizes we can install a solution for every throughput, small or large; at truck, barge or rail tank-filling. The VPS makes you much more independent as an electricity consumer; it can therefore also be applied for peak shaving at high rate periods and as a back-up power unit.
The ultimate solution
Dordtech Power in the Netherlands has developed the unique VPS for the handling of vapour emissions that erupts when loading and discharging petrochemicals at chemical plants, tank storage facilities or refineries.
