STUDY OF THE PROPERTIES OF SODIUM SULFIDE OBTAINED FROM OIL AND GAS PRODUCTION WASTE

open access: yes
Experiments were carried out in a chemical laboratory to obtain sodium sulfide from natural gas processing waste, which contains hydrogen sulfide.  As you know, hydrogen sulfide is a harmful substance that is released in many industries. Issues of cleaning, neutralization, disposal, or use of hydrogen sulfide as a raw material by industrial ...

PRODUCTION OF SODIUM CARBOXYMETHYLCELLULOSE FROM PINE WOOD WASTE AND INVESTIGATION OF ITS PHYSICOCHEMICAL PROPERTIES

open access: yesSERIES CHEMISTRY AND TECHNOLOGY
With the increasing use of wood resources, wood waste disposal is becoming a more pressing issue. Wood waste can be effectively processed and reused, thus reducing environmental impact. Our study proposes using wood waste to produce sodium carboxymethyl cellulose (Na-CMC) with enhanced physical and chemical properties.
