Output Enhanced Using LNG
The trademark product of Saudi Perlite Industries, the industrial insulator Cryolite, is now to be produced using liquefied natural gas (LNG) fuel as opposed to diesel.

The company claims Cryolite is the most reliable insulation material for cryogenic storage tanks and cold boxes.
It's acclaim is due to its widely accepted thermal conductivity of 0.025-0.039 W/m- deg K (0.17 - 0.27 Btu-in/h-ft2- deg F) and it also boasts a density range of 48 to 96 kg per cu m (3 to 6 pcf).
It is used by companies engaged in engineering, procurement and construction of deferent petrochemical factories locally and internationally.
Lately Saudi Perlite has transferred its production process from diesel fuel to LNG for better quality fuel consumption, and also due to an awareness of its  environmental effects.
The origins behind Cryolite lie in the change in today's technological advances
Liquefied gases, which have boiling points as low  as 452øF, have created a demand for storage facilities capable of economically reducing evaporation losses.
While the storage vessels vary as to configuration, type of supports and accessory equipment, a large majority of the vessels are of double wall construction, and the annulus needs to be filled with an effective insulator; Cryolite.
The thermal conductivity of Cryolite insulation at atmospheric pressure conditions has been shown to correlate directly with density.
Cryolite has been applied in several petrochemical plants in both Saudi Arabia and neighbouring states. In the Kingdom, Cryolite has been supplied to major companies including Saudi Aramco, Saudi Yanbu Petrochemical Company (Yanpet), Arabian Petrochemical Company (Petrokemya), Al Jubail Petrochemical Company (Kemya) and National Industrial Gases Company (Gas).
Cryolite is a trusted product used by international contractors including Chiyoda Petrostar and Mitsubishi Heavy Industries of Japan and Germany's Linde.
Perlite is a generic term for naturally-occurring siliceous volcanic rock. The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands by four to twenty times its original volume.
This expansion is due to the presence of two to six per cent combined water in the crude perlite rock. When quickly heated to more than 1600F (870øC), the crude rock pops in a manner similar to popcorn as the combined water vapourises and creates countless tiny bubbles in the heat softened glassy particles.
It is these tiny glass-sealed bubbles which account for the excellent insulating properties and light weight of expanded perlite cryolite.
Expanded perlite can be manufactured to weigh from 32 kg/cu m to 240 kg/cu m, making it especially suitable for use in insulating applications.
Cryolite perlite is used in the manufacture of cryogenic, low temperature and high temperature insulation.
