Ibitekerezo ku giciro cy'amavuta yatwitswe ku isoko mu Bushinwa mu minsi ibiri ishize

Mu minsi ibiri ishize, ubucuruzi bwa peteroli ya calcined coke mu Bushinwa buri ku rwego rwiza, kandi umubare w’ibigo bishya uhagaze neza. Ku ruhande rw’ibyifuzo by’isoko ry’ingufu mu bijyanye n’ibiciro ni rusange, hafi y’iserukiramuco ry’impeshyi, umutwaro wo hasi wakomeje kugabanuka; Ingufu zo kugura aluminium carbone ku isoko ni nziza, ubucuruzi bw’isoko buri ku rwego rwo hejuru, kandi igiciro cy’isoko cya calcined char kiracyahagaze neza by’agateganyo. Isoko rya peteroli rya low sulfure coke ryinjiye ku isoko mu mwuka mwiza, igiciro cy’ibikoresho fatizo bya sulfure bike cyakomeje kuzamuka, amasoko ya graphite electrode na graphite cathode yari akenewe cyane, kandi ibiciro by’ibiciro fatizo bya sulfure bike byari bihagaze neza cyane. Inkunga y’isoko ry’ibikoresho fatizo bya sulfure bike ntiyagabanutse, ishyaka ryo kubika imitungo riri ku rwego rwo hasi ni ryiza, inyungu z’ibigo zariyongereye, kandi byitezwe ko igiciro cya low sulfure coke cyahagaze neza. Isoko ry’ibikoresho fatizo bya electrode riracyari ryiza, kandi imiterere y’ibigo ni myiza, ishyigikira igiciro rusange cy’isoko rya sulfure; Inganda za aluminiyumu zifite ibisabwa bikomeye ku bintu bifatika, isoko ry’ibipimo ni rito cyane, igiciro cy’ibikoresho fatizo kiri hejuru, kandi igiciro ku isoko cy’ibicuruzwa bipima ubunini n’ubunini bya sulfur kirimo kuzamuka. Biteganijwe ko isoko ry’ibipimo bipima ubunini n’ubunini bya sulfur rizakomeza gukora neza.
