Oil Spill Cleanup

Recent developments in the application of lignocellulosic materials for oil spill removal are discussed in this review article. The types of lignocellulosic substrate material and their different chemical and physical modification strategies and basic preparation techniques are presented. The morphological features and the related separation mechanisms of the materials are summarized. The material types were classified into 3D-materials such as hydrophobic and oleophobic sponges and aerogels, or 2D-materials such as membranes, fabrics, films, and meshes. It was found that, particularly for 3D-materials, there is a clear correlation between the material properties, mainly porosity and density, and their absorption performance. Furthermore, it was shown that nanocellulosic precursors are not exclusively suitable to achieve competitive porosity and therefore absorption performance, but also bulk cellulose materials. This finding could lead to developments in cost- and energy-efficient production processes of future lignocellulosic oil spillage removal materials.

Oil Spill Cleanup

ABSTRACT Trailing suction hopper dredges maintain ports and their entrance channels around the world. Several of these dredges have already operated as oil spill cleanup vessels as a secondary assignment. Different types of available oil spill response systems were applied. Recent developments allow these dredges to use their own dredge pumps, making these vessels by far the largest capacity oil spill cleanup vessels available in the world. The add-on system requires no modifications of the vessel and a relatively low investment. Tests have documented very good performance.

Oil Spill Cleanup

ABSTRACT The use of chemical dispersants for the handling of oil spills has had a brief but highly turbulent history. Despite extensive laboratory data and field application experience, their role in oil spill cleanup is still controversial. This paper reviews some of this past history as background in order to derive the pros and cons regarding their use. Opinions vary from an extreme of no use whatsoever to an acceptance of this as the only practical technique to combat an oil spill under rough sea conditions. Improvements in the formulation of dispersants during the past several years are reviewed. These innovations involve modifications to improve effectiveness, application techniques and toxicological properties. A brief outline of the mechanism of dispersing is presented to permit a better understanding of these formulation modifications and the manner in which said changes influence dispersant properties. The future outlook for dispersants, based on current and anticipated research in this field, is also discussed. This research involves biological as well as operational aspects of dispersants.

Oil Spill Cleanup

Abstract When compared on an individual basis to major oil pollution disasters, the average Navy oil spillage incident seems insignificant. However, when the cleanup costs are tallied, these limited oil spills do not appear so small. For example, a one barrel oil spill, discharged from a destroyer berthed at the Long Beach Naval Shipyard, took nine laborers, a boat operator, a truck driver, a crane operator and a supervisor one and a half days to clean up at a cost of $1,300. On the East Coast, the Norfolk Naval Shipyard spends approximately $1,000 an incident in its oil spill cleanup operations. These spills vary between 50 and 500 gallons. From the presented data which defines the limited oil spill, three general statements are derived:1. Limited oil spills are a large problem due to their numerous occurrences.2. Limited oil spills require proper treatment.3. Limited oil spills are expensive to treat. This paper investigates this last statement and by so doing discloses the actual problems which contribute to the high cost of cleaning up limited oil spills. Three factors are discussed:1. The physical conditions affecting an oil spill.,a. Location of the slick,b. Oil Slick Movement,(1) Spreading,(2) Weather, wind and current effects,2. The type of equipment employed.,a. Booms,b. Chemical Dispersants,c. Physical Removal,(1) Skimmers,(2) Straws,3. The completeness of the removal operation. The limited harbor oil spill is expensive and the cost is expected to rise. At the present time, the typical oil spill costs the Navy over $1,000 to clean up. This cost will increase as control agencies rightfully require more removal and more complete removal.

Oil Spill Cleanup

ABSTRACT The Forties oil field in the UK sector of the North Sea is about 100 miles off the Scottish coast. Four steel platforms will eventually produce 500,000 barrels of oil per day, and deliver it by the subsea pipeline and 130-mile landline to the BP Grangemouth oil refinery and the Hound Point oil terminal on the Firth of Forth. Although the safety measures both on the platforms at sea and on the shore installation should largely negate the risk of oil spillage, BP has developed oil spill contingency plans to cover the entire Forties system, from the production platforms to the refinery and tanker terminal. This paper describes these plans and the types of problems involved. The work has required, in part, re-examining methods of oil spill cleanup at sea and on land, bearing in mind ecological problems, and redesigning equipment where necessary; coordinating with relevant authorities, and insuring personnel involved in the plans are adequately trained.

Oil Spill Cleanup

Purpose In recent years, oil spill pollution has become one of the main problems of environmental pollution. Recovering oil by means of sorbent materials is a very promising approach and has acquired more attention due to its high cleanup efficiency. Compared to synthetic fibrous sorbents, the use of natural fibers in oil spill cleanups offers several advantages including environmental friendliness, degradable features and cost-effectiveness. Therefore, studies on developing sorbents using natural fibers for oil spill cleanup applications have become a research hotspot. Design/methodology/approach This paper reviews the work conducted by several researchers in developing oil sorbents from fibers such as cattail, nettle, cotton, milkweed, kapok, populous seed fiber and Metaplexis japonica fiber. Some featured critical parameters influencing the oil sorption capacity of fibrous substrates are discussed. Oil sorption capacity and reusability performance of various fibers are also discussed. Recent developments in oil spill cleanups and test methods for oil sorbents are briefly covered. Findings The main parameters influencing the oil sorption capacity of sorbents are fiber morphological structure, fiber density (g/cc), wax (%), hollowness (%) and water contact angle. An extensive literature review showed that oil sorption capacity is highest for Metaplexis japonica fiber followed by populous seed fiber, kapok, milkweed, cotton, nettle and cattail fiber. After use, the sorbents can be buried under soil or they can also be burned so that they can be vanished from the surface without causing environmental-related issues. Originality/value This review paper aims to summarize research studies conducted related to various natural fibers for oil spill cleanups, fiber structural characteristics influencing oil sorption and recent developments in oil spill cleanups. This work will inspire future researchers with various knowledge backgrounds, particularly, from a sustainability perspective.

Abstract: Algae (both micro and macro) have gained huge attention in the recent past for their high commercial value products. They are the source of various biomolecules of commercial applications ranging from nutraceuticals to fuels. Phycobiliproteins are one such high value low volume compounds which are mainly obtained from micro and macro algae. In order to tap the bioresource, a significant amount of work has been carried out for large scale production of algal biomass. However, work on downstream processing aspects of phycobiliproteins (PBPs) from algae is scarce, especially in case of macroalgae. There are several difficulties in cell wall disruption of both micro and macro algae because of their cell wall structure and compositions. At the same time, there are several challenges in the purification of phycobiliproteins. The current review article focuses on the recent developments in downstream processing of phycobiliproteins (mainly phycocyanins and phycoerythrins) from micro and macroalgae. The current status, the recent advancements and potential technologies (that are under development) are summarised in this review article besides providing future directions for the present research area.
