What is the advantages of solvent extraction as compared to mechanical operation?

∙ 11y ago
- Instead of using heat and pressure to facilitate in the extraction of essential oils from the plant material, the use of solvents make a safer alternative. The purity of the oil is preserved since both heat and pressure are known to contribute in destroying the natural chemical composition of the plant oil.
- As compared to the other extraction methods, this one is actually much friendlier to your budget. Plus, it does not take a great deal of time so you won't have to spend all day doing this.

What are good things about vulcanized rubber?
Vulcanization is a chemical process for converting rubber into more durable materialsby adding sulfur. Non-vulcanized (uncured) natural rubber is sticky, deforms easily when warm, and is brittle when cold. Vulcanized rubber is less sticky and have superior mechanical properties compared to non-vulcanized rubber.Such as:better weather resistance (sunlight, temperature changes, water and snow)better durability (stands mechanical wear better)better elasticitybetter mold ability (easier to make things out of)
Does 316sst have better corrosion resistance than 304sst in di water?
Compared to 304 grade stainless steel, the 316 has higher strength, can withstand higher temperatures, and yes it can resist corrosion better. One factor is the molybdenum content in the 316 grade which gives it the overall corrosion resistant properties. The downside, 316 stainless steel grade is way more expensive than 304.
What are the cons of thermal desalination?
Advantages· Distillation offers significant savings in operational and maintenance costs compared with other desalination technologies. · In most cases, distillation does not require the addition of chemicals or water softening agents to pretreat feedwater.· Low temperature distillation plants are energy-efficient and cost-effective to operate.· Many plants are fully automated and require a limited number of personnel to operate.· Distillation has minimal environmental impacts, although brine disposal must be considered in the plant design.· The technology produces high-quality water, in some cases having less than 10 mg/1 of total dissolved solids.· Distillation can be combined with other processes, such as using heat energy from an electric-power generation plant.Disadvantages· Some distillation processes are energy-intensive, particularly the large-capacity plants. «Disposal of the brine is a problem in many regions. · The distillation process, particularly MSF distillation, is very costly.· Distillation requires a high level of technical knowledge to design and operate.· The technology requires the use of chemical products, such as acids, that need special handling.
How steam required for steam tracing of jacketed lines is calculated how much steam required for sulfur melting?
The steam required for steam tracing is calculated on the basis of the amount of heat transfer that is required or the temperature that you want to maintain with the help of steam. It also depends on the pipe material through which the steam is passing,the condition of the steam that whether it is saturated or superheated etc. Overall heat transfer cofficient is calculated considering all the factors like fouling or scaling,inside and outside dia. , surface area etc. After calculating the amount of heat to be transferred, the requirement of rate of steam is calculated. Generally, Low pressure steam is used as it has got more latent/Sensible heat as compared to MP or Superheated steam.
What is supercritical boiler?
The following extract taken from an article by Ingo Paul in Energy Issues No 19 April 1999 published by the World Bank [external link] briefly describes the difference between a subcritical and a supercritical boiler. "Supercritical" is a thermodynamic expression describing the state of a substance where there is no clear distinction between the liquid and the gaseous phase (i.e. they are a homogenous fluid). Water reaches this state at a pressure above 22.1 megapascals (MPa) The "efficiency" of the thermodynamic process of a coal fired power (sic) describes how much of the energy fed into the cycle is converted into electrical energy. The greater the output of electrical energy for a given amount of energy input, the higher the efficiency. If the energy input to the cycle is kept constant, the output can be increased by selecting elevated pressures and temperatures for the water-steam cycle. Up to an operating pressure of around 19 MPa in the evaporator part of the boiler, the cycle is sub-critical. This means, that there is a non-homogeneous mixture of water and steam in the evaporator part of the boiler. In this case a drum-type boiler is used because the steam needs to be separated from water in the drum of the boiler before it is superheated and led into the turbine. Above an operating pressure of 22.1 MPa in the evaporator part of the boiler, the cycle is supercritical. The cycle medium is a single phase fluid with homogeneous properties and there is no need to separate steam from water in a drum. Once-through boilers are therefore used in supercritical cycles. www.whizkris.com
