Fe ^ C40M POLISH PEOPLE'S REPUBLIC PATENT DESCRIPTION No. 45751 Gryfino Dry Distillation Factory, Poland KL. 26 d, 9/23 The method of cleaning gas pipes in hard coal degassing plants from organic impurities, especially from naphthalene The patent has been in force since April 4, 1961. various organic products in the lines, especially naphthalene. They cause a reduction in the internal diameter of these wires, and often lead to their complete obstruction. These deposits were usually removed with the use of solvents such as solvent, benzene, toluene, xylene, acetone and tetraline. It was found that the cleaning of the above-mentioned pipes is very suitable *). of the invention are Jerzy Bobkowski, MSc Stanislaw Hulisz, Zygmunt Michalak and Janina Hulisz. is breaking oils obtained by dry distillation of hardwood. They dissolve undesirable deposits very well. Before they are used to clean gas lines, they are treated with water and possibly bases to remove acid components causing corrosion of the lines, and then by fractional distillation under The characteristics of the oils used in the process according to the invention are given in the table on the next page. * These oils are ketone oils Oils obtained by distilling deciduous wood tar at atmospheric pressure tar oils b) light tar oils Oils obtained by distilling deciduous wood tar in a vacuum of 20 mm Hg a) the lightest tar oils b) light tar oils Density 0.905 0.950 0.905 1.037 0.902 1.031 Boiling point range 1 ° C 70-98 70-160 70—110 110—180 70— 99 105—163 Ketones% 20—30 10—19 15—27 • 7—10 19—31 7—12 Emergency Esters% 5—8 3—6 5—6 3—5 5 —7 4 ^ -6 t Other ingredients% 60 70 60 80 60 80 Dry residue% 2.0 4.0 2.7 3.0 1.3 2.4 The method according to the invention is simple and cheap.
