Liquidation of Oil and Petroleum Products Spills Based on Use of NA and CA-Differences of Zeolite

Abstract

The article discusses the use of ecologically and economically practical proved methods of neutralizing the soil ecosystems in Yakutia after emergency oil spills. Experimental studies have been made to develop a new biosorbent based on a natural sorbent. The natural zeolite Na and CA-differences from the Khonguruu deposit (The Republic of Sakha (Yakutia), Russia) is used as a base for obtaining the biosorbent. The necessary typification of zeolite deposits revealed at the stage of exploration, in order to determine the field of practical application of raw materials in the preparation of the field for industrial development. The types of raw materials according to the cationic composition difference are identified: clinoptilolite-heulandite and heulandite. A brief description of the material composition and averaged physico-chemical characteristics of various types of zeolite raw material is given. We present the results of the experimental application of hydrocarbon oxidizing microorganisms (HOM) immobilized on zeolite (clinoptilolite- heulandite series) from the Khonguruu deposit in oil-contaminated soils. It has been established that the obtained biomineral compositions provide a significant activation of petroleum hydrocarbons (HC) biodegradation in the soil. In general, the technology of using zeolite raw materials for cleaning up oil spills from different types of permafrost soils provides a significant ecological and economic effect, thus contributing to the reduction of the time for rehabilitation of disturbed lands and the improvement of the environment in the disturbed territory.

Study of the Possibility of Using Na- and Ca-Differences of Zeolite for the Drinking Water Purification

“…Physical and chemical properties of zeolite rocks of deposits by types of raw materials vary: the content of zeolites in the rock, % -70 -98; ion exchange capacity, mg-eq/g-0.16 -1.91; water adsorption properties at P / Ps=1.0, % -10.34 -12.03; thermal stability, °C -700; optimal dehydration temperature, °C -300 -550 [13][14][15].…”

Novel Insights into the Influence of Soil Microstructure Characteristics on the Migration and Residue of Light Non-Aqueous Phase Liquid

“…Chemical spill caused by tank bottom corrosion, pipeline damage, or facility explosion has increased the frequency and harm degree of soil pollution incidents, with the spill of petroleum products especially being the most frequent [ 1 , 2 , 3 ]. Petroleum products (e.g., diesel) are water insoluble or sparingly water soluble, which belongs to light non-aqueous phase liquids (LNAPLs) [ 4 ].…”
