“…The process is easily understandable and simple in operation as compared to other techniques that may involve designing of turboexpanders, catalytic reactors or de-methanizer, depropanizer, debutanizer. The raw material kerosene can be recovered back by distillation 90% of the LPG can be recovered from off-gases through this process [14,15].…”

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.

“…The petroleum industry generates mainly gaseous pollutants and heavy metals in waste water stream (Chan et al, 2016). Carbon (iv) oxide, nitrogen oxides and methane, generally termed greenhouse gases (GHGs) generated from petroleum refineries are the prominent obnoxious gases that are responsible for global warming (Callan and Thoma, 2004;Amanda et al, 2010;Giwa et al, 2017).…”

“…Some of these approaches do have some drawbacks making it difficult for operators of refineries to adopt. For example, carbon capture and storage is very expensive and can cost even up to $162 per ton of CO2 (Chan et al, 2016). Most refineries would prefer to vent their emissions directly in order to save cost.…”

The high volume of green house gases released from petroleum refineries has contributed greatly to global warming. The crude distillation unit of a refinery being an energy-intensive unit generates high volume of greenhouse gases. Unlike solid and liquid pollutants that can easily be handled and treated, gaseous pollutants are difficult to handle once they are generated, hence an effective means of reducing their generation is paramount.Â Because of the cost penalty placed on defaulters, emission trading scheme has been an effective way of controlling the release of these obnoxious gases into the environment as refiners would seek alternative processing schemes that reduce emissions. The crude distillation unit of the refinery under study was simulated in Aspen Hysys. The unit was designed to process 125,000bpsd of a blend of three Nigerian crudes. Greenhouse gases from the unit were targeted from direct (heating sources) and indirect (electricity usage) respectively. The concept of global warming potential was adopted to estimate the carbon (iv) oxide equivalent of the greenhouse gases from the unit. A methodology to allocate emission quota to a refinery was developed and a carbon fee of $5 per tonne was placed for above- limit emissions. The crude distillation unit was found to have a base generation of 491576.27tonne/yr of carbon (iv) oxide equivalent while it pays $491,576.25per year for above-limit emission. The sensitivity analysis revealed that the gross profit is quite sensitive to carbon fee.Â Â

“…The CO 2 concentration in the atmosphere is increasing every year, as well as global warming and its effect on climate change (Barbosa et al, 2016;Chan et al, 2016;Hussain et al, 2015;Nouri and Ebrahim, 2016;IPCC, 2013;Seo et al, 2014). Preventing the growth of carbon dioxide emissions in the atmosphere is essential for achieving the global warming reduction target (Dutcher et al, 2015).…”

Aqueous amine solutions are benchmark solvents for CO 2 capture and their operational drawbacks are well-known. In order to overcome these problems, the support of amines on solid materials appears as an option for CO 2 capture. Cellulose is a versatile and low-cost material that can be used as a support. This study reports chemical modification of cellulose fibers extracted from rice husk with different amines and their potential for CO 2 capture. The obtained compounds were characterized by different techniques. The CO 2 sorption capacity was gravimetrically assessed in a Magnetic Suspension Balance. Quantum mechanical simulations and experimental results revealed that-NH-and-NH 2 represent major working sites of the employed compounds. The best result for CO 2 sorption was attained for the amine-modified cellulose CL-D-400 with a sorption capacity of 409 µmol CO 2 /g at 1 bar and 1091 µmol CO 2 /g at 10 bar with amine concentrations as low as 2 × 10-6 mol/mg.
