“…Stabilization of petroleum wastes is performed through the addition of additives to reduce the moisture content, mobility, and toxicity levels, while solidification of PWs would remove the free liquid, increase the mechanical strength, and produce a monolithic solid product. The end product can be applied as construction materials depending on certain properties [3,8,9]. Fly ash, lime, and Portland cement are among the additives used for the S/S of petroleum waste.…”

Petrochemical is a vital pillar industry for the national economic growth wherein the past few years, it has produced a huge amount of petroleum sludge. Petroleum sludge (PS) contains toxic and carcinogenic-mutagenic compounds and heavy metals, which are a major source of pollution in the environment. Thus, it needs to be properly treated and disposed of. Correspondingly, this paper presents a review of the techniques to treat petroleum waste to effectively immobilize the heavy metals and highlights their possible application as construction materials. This review concludes that each treatment method (i.e., solidification, stabilization, incineration, bioremediation, centrifugation, etc.) has its own merits and demerits and may be more suitable for certain applications than others. The use of pyrolysis, solidification, and stabilization techniques has been demonstrated to be potentially beneficial in protecting the environment from contaminants in PS and further recycling PS as cementitious materials. However, the selection of suitable treatment methods has to be made based on the chemical composition of the waste, method capacity, costs, and disposal standards. Therefore, an overall evaluation is required prior to treatment method selection to ensure the safe disposal or recycling of petroleum waste. This review could improve basic knowledge of PS treatment and disposal techniques and serve as a future guide for recycling PS as a building material.

“…The tremendous amount of wastes generated is alarmingly increasing as the production of crude oil becomes more important in time because crude oil is the sole source of energy and acts as feedstock in refineries [ 2 ]. Oily sludge is the result of several processes of the oil industry (wells drilling, crude oil pools, refining, transporting, and storage tanks) [ 3 ]. Oily sludge is a hazardous waste containing a complex mixture of different emulsified petroleum hydrocarbons, water, heavy metals, and solid particles.…”

In the industries of petroleum extraction, a large volume of oily sludge is being generated. This waste is usually considered difficult to dispose of, causing environmental and economic issues. This study presented the novel experimental method of manufacturing mortar used in civil construction by cement and oily sludge ash (OSA). The defined method was described with a logical experimental study conducted to examine a feasible manufacturing method for casting cement-based mortars by partially replacing cement with OSA. Replacement concentrations for OSA ranged from 0 to 20 percent by cement weight, while the water-to-cement (w/c) ratio was varied from 0.4 to 0.8, and the amount of sand was kept constant. The strengths and absorption rate of the mortar were monitored for 28 days. The OSA contains a crystalline structure with packs of angular grains. Because of OSA in the cement-based mortar mixtures and water-to-cement ratios, the mechanical strength was improved significantly. However, the water absorption trend increased linearly. Using variance analysis, the influence of OSA and w/c ratio on the behavior of mortar was acquired. The developed models were significant for all p-value reactions of <5%. Numerical optimization results showed that the best mixture can be obtained by replacing 8.19 percent cement with OSA and 0.52 as a ratio of w/c.

“…The main areas of producing petroleum sludge are crude oil storage vessels and the separation of water from oil [ 23 ]. The petroleum types and sources are the main factors that influence the petroleum sludge complexity [ 28 ]. The mixture of petroleum sludge is mainly generated due to sedimentation and accumulation of crude oil in the storage tanks [ 29 ].…”

Petroleum sludge is a waste product resulting from petroleum industries and it is a major source of environmental pollution. Therefore, developing strategies aimed at reducing its environmental impact and enhance cleaner production are crucial for environmental mortar. Response surface methodology (RSM) was used in designing the experimental work. The variables considered were the amount of petroleum sludge ash (PSA) in weight percent and the ratio of sodium silicate to sodium hydroxide, while the concentration of sodium hydroxide was kept constant in the production of geopolymer mortar cured at a temperature of 60 °C for 20 h. The effects of PSA on density, compressive strength, flexural strength, water absorption, drying shrinkage, morphology, and pore size distribution were investigated. The addition of PSA in the mortar enhanced the mechanical properties significantly at an early age and 28 days of curing. Thus, PSA could be used as a precursor material in the production of geopolymer mortar for green construction sustainability. This study aimed to investigate the influence of PSA in geopolymer mortar.
