Quality adjustment solutions

Lowering wobbe index through ballasting

Most of the LNG produced worldwide has a wobbe index higher than the maximum allowed values for natural gas in the UK. The ballasting installation at the terminal is used to inject liquid nitrogen in the LNG flow in order to lower the wobbe index and gross heating value of natural gas after regasification. This enables shippers to send-out natural gas from the terminal to the UK or the Zeebrugge hub.

Downstream swaps

Another solution to meet downstream quality specifications is offered through swapping or mixing gas flows, e.g. mixing or swapping the gas flows coming from the Zeepipe Terminal (ZPT) with gas flows coming from the LNG terminal.



Mixed send-out

Quality adjustment is also possible by combining one quality of LNG with another quality of LNG at send-out. Different qualities of LNG are stored in different storage tanks and can be regasified together in certain ratios to meet specific requirements.

Tips for using search operators

Use "quotation marks" to search for a series of words or a phrase in a specific order.

Boolean operators

You can find a group of words or a phrase by using the link words AND, OR and NOT:
known as Boolean operators, these words are used to combine terms in the search field.

  • AND: All the search terms must be included in the publication. Typing in Apple AND Pear will return publications containing both the word Apple and the word Pear.

     

  • OR :  At least one of the search terms must be included in the publication. Typing in Apple OR Pear will return publications containing either the word Apple or the word Pear or both.

     

  • NOT: The term preceded by NOT must not be included in the publication. Typing in Apple NOT Pear will return publications containing the word Apple but not the word Pear.
