What are the benefit of diesel fuel ?_Waste Oil Distillation Plant

In today's world, where fuel prices are increasing as a consequence of spiraling demand and diminishing supply, you need to choose a cost effective fuel to meet your needs. Diesel fuel is priced moderately higher than gasoline but diesel has a higher energy density, i.e. more energy can be extracted from diesel as compared with the same volume of gasoline. Therefore, diesel engines in automobiles provide higher mileage, making it an obvious choice for heavy-duty transportation and equipment. Diesel is heavier and oilier compared with gasoline, and has a boiling point higher than that of water.  And diesel engines are attracting greater attention due to higher efficiency and cost effectiveness.

Diesel engines are commonly used as mechanical engines, power generators and in mobile drives. They find wide spread use in locomotives, construction equipment, automobiles, and countless industrial applications.  Their realm extends to almost all industries and can be observed on a daily basis if you were to look under the hood of everything you pass by. Industrial diesel engines and diesel powered generators have construction, marine, mining, hospital, forestry, telecommunications, underground, and agricultural applications, just to name a few. Power generation for prime or standby backup power is the major application of today's diesel generators.

Essential oil (EO) distillation units, which are commonly installed on farms, have difficultly accessing knowledge centers. The apparent simplicity of the process hides unwanted losses and deviations that go undetected and, therefore, not corrected. This article proposes improvements to the process that are based on &#;4.0&#; technologies in order to detect and correct two important deficiencies, with an impact on the yield, quality and environmental performance. The first deficiency comprises the steam channels that are formed through green mass (channeling), are well known and are considered normal by EO producers. Without detection and correction, this negatively affects the extraction results. The second is the lack of technology that is able to automatically determine the extraction endpoint. Smart sensing, control, self-configuration and the dynamic determination of improved process parameters make up a set of actions undertaken by a smart extraction plant (50-liter capacity). Nineteen experiments using lemongrass (Cymbopogon citratus) exhibited remarkable 24% and 10% improvements in the yield and quality, respectively. Energy consumption and a more than 50% reduction in the processing complete the set of results achieved. In addition to manufacturing costs and the utilization of capacity, better sustainability indicators are positive consequences of this technological updating.

Introduction

Essential oils (EO) are aromatic liquids and volatile substances that are obtained via extraction from various parts of plants, such as their flowers, leaves, roots, barks, fruits and seeds. Chemically, they comprise a range of fractions from the terpenoid family that exist in a homogeneous mixture, from the most volatile to the heaviest [1]. Lemongrass (Cymbopogon citratus) is one of the plants most used to obtain essential oil due to its sweet and attractive aroma; it is therefore widely applied in the cosmetics and food industry for the development of perfumes, bath soap, tea, and cooking spices, in addition to its use in traditional medicine as an antimicrobial and antioxidant agent [2]. These properties are mainly related to the composition of lemongrass EO, which comprises a significant number of bioactive compounds, such as citral (with two isomers: geranial and neral), myrcene, isoneral, isogeranal, geraniol, geranyl acetate, citronellal, citronellol, germacrene-D, and elemol, in addition to other bioactive and mineral compounds [3]. Noteworthy in this composition is the presence of citral, which is also considered a quality factor of lemongrass EO [4] due to its important bioactive properties [5].

It is common knowledge that the extraction method employed is one of the most critical factors in the process of obtaining EO. Steam distillation is widely applied in the essential oil industry, accounting for more than 93% of the oil volume produced worldwide [1]. Via the use of steam distillation, the technological scenario of the EO extraction industry confers interesting opportunities with regard to enhancements in the yield, quality, energy efficiency, and operational effectiveness [6]. The dimension of sustainability is equally important, as the concern for environmental performance continues to grow. So-called green extraction, which comprises a set of design and operational principles, aims to mitigate this specific area of concern [7, 8]. Usually installed next to farms in rural areas [9], these extraction units are mostly characterized as small and medium-sized companies (SME) that use extremely simple processes and, therefore, represent an interesting opportunity for technological update [10]. The fact that they are far from developed industrial centers means that they experience difficulties when attempting to access innovative technology, both in terms of suppliers and knowledge [11].

Despite its importance in this context, obtaining EO through steam distillation has significant disadvantages, such as its long duration; this can have an impact on the loss of thermosensitive components and reduce the quality of the oil extracted [12]. When duly applied, technological elements that are allied to quantitative and qualitative improvements are able to enhance performance, thus contributing to a minimized energy and water consumption, as well as a reduction in all other manufacturing resources (labor, capacity, maintenance) and the planted area [13]. Industry 4.0 promotes the concept of smart manufacturing and its use as a sustainable process [14]. The significance of applying this technological framework to EO distillation is clear, as it offers operational advantages such as improved yields and quality, as well as reduced production costs and increased product value.

Thus, this study proposes technological improvements to the steam extraction process by targeting two identified weaknesses: channeling detection and correction (or attenuation), and the automatic determination of the process duration, using "industry 4.0" tools to obtain lemongrass EO. The control of the condensation water temperature is also part of the proposal. A long chain of positive results arises from these improvements, beyond the important benefits observed regarding the yield and quality. A better use of capacity, the postponement of investments and enhanced financial and environmental performances are factors that are more important than the operational aspects of the factory floor. For perspective, the environmental performance of the EO industry is indeed not limited to the indicators of energy and water consumption during the process. When there is an improvement in yield, less acreage is needed to produce the same amount of essential oil; this means that fewer supplies for the care of soil, less irrigation water and equipment, and a smaller work force are required.
