Development of A Method of Utilization of Oil and Gas Industry Waste at Pereshchepyno Field (Ukraine)

The object of research is the technological solutions for the construction of sludge barns at the Pereschepyno field (Ukraine). One of the most problematic places is the lack of reliable insulation of sludge barns and storage facilities. The study used a screen type «wall in the soil» of elements of soil cement, which prevents the filtration of the aqueous phase. The screen was built monolithic. It is proposed to arrange the shade between the centers of the curtain equal to 0.8 of the diameter of the element. It is proposed to make elements from soil cement by the brown-mixing method. After 28 days (hardening of the elements) up to 60 % of the soil was removed from the waste storage area. This is due to the fact that the proposed method of arrangement of waste storage has a number of features. Over time, the strength and permeability of the aqueous phase of soil cement increase. It is proposed to fill the storage with drilling waste after the enclosing elements have hardened. In order for the soil to have a suitable humidity of 4–5 %, it is proposed to dry it outdoors. It is proposed to build a cover over the soil dump. If the optimum humidity of the mixture is not obtained after drying and mixing the waste with the soil, it is proposed to add a drying additive (ash removal of Mykolayiv thermal power plant). The amount of additive is from 1.5 to 3 % depending on the type of soil. Next, it is proposed to seal the layers of sludge and loam by rammers. After compaction, the operation is repeated. Compaction of soil layers is proposed to be carried out at optimum humidity. In comparison with similar known methods, this method provides the following advantages: low cost of manufacture due to the use of a waterproof layer of soil as the bottom of the structure; high water resistance – W12; high compressive strength; environmental safety and durability

Methods to Improve the Quality of Ceramic Products

This article presents the results of experimental studies aimed at improving the physicomechanical properties of effective hollow ceramic stones using various technological methods that will disperse, homogenize and structure the ceramic mixture by introducing industrial waste with high alumina content, dispersed reinforcement, and also mechanical activation of the molding material, accompanied by the fragmentation of clay particles to a colloidal degree of dispersion, allows eliminating the aging process. The main molding characteristics of the investigated mixtures were determined, X-ray phase analysis of ceramic masses and a shard of the control composition was performed and after dispersion, activation modes were worked out, strength characteristics of ceramic samples made of dispersed clay raw materials were determined
