A new wet limestone−gypsum process for flue gas desulfurization (FGD) has been developed. The main difference compared to a conventional wet FGD process is the ability of the new process to utilize granular limestone directly as a desulfurizing reagent. Thus, the pulverizing of limestone, which causes power consumption, can be …

Hydrom, the green hydrogen orchestrator of the Sultanate of Oman, announced signing two new green hydrogen projects in Dhofar worth $11 billion. The signings follow the successful completion of Hydrom's second round of auctions bringing the total hydrogen production in Oman to 1.38 million tonnes per year (mtpa) by 2030.
Our Granulated Lime is made from a micronized powder which is pelleted to make it easy to apply to the crop without producing clouds of dust. Immediate pH improvement is achieved followed by a fast response from the crop. Correct and fast pH adjustment allows maximum utilization of expensive fertiliser. It is also an excellent source of calcium ...
The carbonate rock of the Qiulitage Formation is a significant stratum for oil and gas exploration in the Tarim Basin.

Pelletized limestone, often referred to as pelletized lime, is created when limestone rock is crushed into a powder and then granulated. The powdered lime is ground to a very fine consistency, allowing the product to dissolve quickly and start working fast.
Granulated lime is spread at a rate of 3:1, Ground Limestone to Granulated Limestone. For example, If you require 3 tonnes/acre of ground limestone, therefore this is equivalent to 1 tonne of granulated lime spread over 5 years. In this example, the annual application of granulated lime is 200kg/ha per year. (1,000/5 =200kg/ha/yr)
