“…Mercury will prevail long in the environment after that due to mercury re-volatilisation and Table 5 Mercury in fossil fuels and potential amounts available for release of it was all released by fuel combustion. The mercury removal yield relates to cleaning systems applied to exhaust and to fuels production (Mojammal et al 2019;Bingham 1990;Selin 2009;Wilhelm 2001;Wilhelm et al 2007;Wu et al 2017 Coal 2,500,000 0.8; 0.5-5 2,000,000 1,300,000-5000,000 80 400,000 Sum 3,620,000 2,244,000 1,420,000-6,230,000 453,000…”

How mercury flows from geological sources to society and to the environment was modelled for this study. The industrial dynamics of mercury was modelled and included in the integrated assessment model WORLD7. The simulated mercury losses were used as input for a simplified global model for environmental pollution. The outputs were analysed and used to assess mercury pollution amounts and supply to society. In fossil fuels, there are a potential stock of 2 million tons in coal and other hydrocarbons, and 450,000 tons of that could be released to the environment if the fossil fuels are all to be burned. Such release would potentially cause major environmental damage and a significant human health risk. The simulations suggest that environmental mercury flows may peak in 2025, and slowly decline as mercury gets immobilized in nature. The simulations show that the pollution from technical use is eliminated by putting the 2013 Minimata Convention into effect, but that environmental pollution from fossil fuels combustion and from environmental re-emissions will remain a significant problem for the next decades.

“…The buildup stream from the membrane exhausted in LPG and enhanced in hydrogen and lighter hydrocarbon gases (ethane, methane), remains at pressure and can be sent straightforwardly to the fuel headers or for additional hydrogen purification. Now and again, the hydrogen purity is sufficiently high to permit direct recycle to other refinery methods is appeared in Figure 1 [10]. Vapour separation technology includes gas reception, gas sweetening, drying and filtration, followed by LPG recovery using a combination of turbo-expander technology and hydrocarbon washing to achieve high recovery of LPG.…”

“…This combined residue gas stream (comprising the ethane and lighter components) can then be routed to the plant fuel system. Removal of the LPG components from the plant fuel gas system may also improve the operation of fired equipment throughout the facility [3,10]. Depending on the feed pressure, some limited amount of feed compression may still be required with PRO-MAX.…”

With the growing need and demand for petroleum fuels in the industrial, automotive and domestic sectors, it has become the need of time to address this problem. The important question is, what engineers can do in this regard. There is a simple solution to cater this problem, the production trends worldwide are increasing every year, but still, the demand keeps increasing exponentially. One way is to stress emphasis on reducing the wastage of these precious fuels and, at the same time, implement methodologies and techniques to recover these. The research caters to cope up with the shortage of LPG within Pakistan. Since LPG is a fuel that is being used in the industrial, automotive as well as domestic sector, adequate responsive measures should be taken to meet the market requirements. This research focuses on the technique to recover LPG from refinery off-gases. Since off-gases usually are flared of by most of the refineries leading to potential loss of lighter end fuels like LPG. The article encloses a detailed proposal of a recovery plant that makes use of simple techniques and efficient process accompanied by economical and feasible solutions.

“…Landfilling is the common way of disposal of the sludge produced from the liquid effluent treatment plants of an oil industry [6]. Waste oil sludge product is one of the by-products of the categorized refineries (oil refinery A) [7]. The huge quantity of oily sludge originates from the upstream and downstream processes [8].…”

Oily sludge (OS) contains toxic compounds such as aromatic hydrocarbons and polyaromatic hydrocarbons; oily sludge is hard to dehydrate due to its high viscosity. Generally, it contains about (40 to 50 wt.%) of water. However, this research's oily sludge sample contains about (50 wt.%) of water collected from North Refineries Company Baiji (NRC). NRC Baiji yields around 3000-3500 m 3 annually of oily sludge. This research aims to study oily sludge specifications, thereby prove suitability to undergo the thermochemical process. The physical properties of oily sludge samples have been conducted, it indicated the complex formula of oily sludge, and it has a serious effect on human health and environmental issues. In this study, the oily sludge has a low heating value (LHV) of 6.705 MJ.kg -1 (as received) and a high heating value (HHV) of 9.465 MJ.kg -1 for a dried sample at 105 °C for 24 h, which indicate that it is a rich in carbon content. FTIR has been carried out to obtain the function group characterizations. The TGA of the oily sludge sample as received showed the greatest loss in volume (39%), while the loss in volume for the dried sample was (15%). The thermochemical conversion process eco-friendly, rapid, short time, moderate temperature, and low-cost. It is used for the total reclamation of waste. It is a novel way of totally converting oily sludge for solid carbon fuel production.
