Facilities Topics
Part 1 : Shale gas is typically considered an “unconventional” resource, along with tight gas and coalbed methane. Of these three, coalbed methane (CBM) has several characteristics that make it quite different than shale gas and tight gas, including: shallow depth, low pressure and temperature, and the need for a significant early life “de-watering...

LNG / Gas Plants: Problems & Solutions
There are three key processing units, viz. Acid Gas Removal Unit (AGRU), Mol Sieve Dehydration Unit (MSDU) and Mercury Removal Unit (MRU) that are common in both gas processing, and LNG facilities. In this TOTM, we discuss some common operating problems associated with these process units and suggests ways to troubleshoot the root cause of these op...

Development of 7% Nickel Steel for LNG Storage Tanks
The construction costs of LNG storage tanks are very high, mainly due to the availability and cost of nickel. Most LNG storage tanks built in the modern era use 9% wt nickel steel as the materials of construction because of the materials well documented toughness at cryogenic temperatures. This article looks at advances in cryogenic metallurgy in...

LNG Containment Tanks: Why is the internal liner 9% Ni and not 7% Ni?
The base material for the tank containing the liquid gas (such as LNG) at below -165°C (-265°F) must remain ductile and crack resistant with the highest level of safety. The material must also permit welding without any risk of defects, for example, induced brittle fracture. Stainless steels, aluminum and 9% nickel steels can be used as they do no...
