RECOVERY OF CRUDE OIL SPILLS FROM WATER WITH PLATANUS ORİENTALİS L. ADSORBENT

Öz

Since the Industrial Revolution, industrial developments and the discovery, production, and processing of petroleum have significantly increased environmental pollution risks. In recent years, the rise in the volume of oil-contaminated water worldwide has led to severe environmental problems as these waters are discharged into the environment. Therefore, the treatment of oil contaminated waters is of critical importance for the protection of ecosystems. Traditionally, oil-contaminated waters are treated using physical, chemical, and biological methods. However, many of these methods fail to completely remove small suspended oil particles and dissolved components from water, involve high operational costs, and lead to the production of hazardous sludge, particularly on offshore platforms. In this context, adsorption has emerged as an attractive alternative for removing oil contaminants due to its low cost and ease of application. In this study, the cellulosic fibers surrounding the seeds of the oriental plane tree (Platanus orientalis) were selected as an adsorbent for the removal of oil from water. The adsorption capacity of the adsorbent was measured according to the ASTM F726-06 international standards. Optimized oriental plane tree seeds were subjected to short- and long-term oil adsorption tests as well as dynamic degradation tests. The tests were conducted using simulated seawater containing 3% salt. The results of the 24-hour long-term tests revealed that the adsorption capacity of the fibers surrounding the oriental plane tree seeds was 26.21 g of oil per gram of adsorbent. The findings demonstrate that oriental plane tree seeds are a cost-effective and highly efficient alternative to other adsorbents due to their high oil retention capacity and ease of availability.

PLATANUS ORİENTALİS L. ADSORBANI İLE HAM PETROL DÖKÜNTÜLERİNİN SULARDAN GERİ KAZANIMI

Öz

Sanayi devriminden bu yana endüstriyel gelişmeler ve petrolün keşfi, üretimi ve işlenmesi, çevresel kirlilik risklerini artırmıştır. Özellikle son yıllarda, dünyadaki petrol kirliliği içeren su hacmindeki artış, bu suların çevreye boşaltılmasıyla ciddi çevresel sorunlara yol açmıştır. Bu nedenle, petrol içeren suların arıtılması, ekosistemlerin korunması için hayati öneme sahiptir. Geleneksel olarak, petrol içeren sular fiziksel, kimyasal ve biyolojik yöntemlerle arıtılmaktadır. Ancak, bu yöntemlerin çoğu, su içinde asılı kalan küçük petrol partiküllerini ve çözünmüş bileşenleri tam olarak ortadan kaldıramamakta, yüksek işletme maliyetleri gerektirmekte ve açık deniz platformlarında tehlikeli çamur oluşumuna neden olmaktadır. Bu kapsamda, petrol döküntülerinin adsorpsiyon yoluyla giderimi, düşük maliyeti ve kolay uygulanabilirliği nedeniyle dikkat çekici bir alternatif olarak öne çıkmaktadır. Bu çalışmada, Petrolün sudan uzaklaştırılmasında, doğu çınarı (Platanus orientalis) tohumlarının çevresindeki selülozik lifler adsorban olarak tercih edilmiştir. Adsorbanın petrol adsorplama kapasitesi, ASTM F726-06 uluslararası standartlarına uygun testlerle ölçülmüştür. Optimize edilen doğu çınarı tohumlarının, kısa ve uzun vadeli petrol adsorpsiyonu testleri ile dinamik bozunma testleri gerçekleştirilmiştir. Simüle edilmiş deniz suyu (%3 tuz içeriği) kullanılarak yapılan testler sonucunda, 24 saatlik uzun vadeli değerlendirmede adsorban kapasitesi 26,21 g petrol/g adsorban olarak belirlenmiştir. Elde edilen sonuçlar, doğu çınarının kolay temin edilebilir olması ve yüksek adsorpsiyon kapasitesi nedeniyle benzer yöntemlerde kullanılan diğer adsorbanlara kıyasla daha ekonomik ve etkili bir seçenek sunduğunu göstermektedir.
