Ethylene Oxide Addition

Ethylene oxide (also known as ETO or oxirane) is a flammable gas with a somewhat sweet odor. Ethylene oxide is one of the most important raw materials used extensive in chemical production. It dissolves easily in water, alcohol, and most organic solvents. Ethylene oxide is produced in large volumes and is used to make other chemicals, especially ethylene glycol, a chemical used to make antifreeze and polyester. Polyethylene glycols are used in perfumes, cosmetics, pharmaceuticals, lubricants, paint thinners and plasticizers. Other products of ethylene oxide Ethanolamines are used in the manufacture of soap and detergents and for purification of natural gas. 
With all the merits Ethylene oxide is highly toxic to humans. 
Sierra Instrumentation & Controls in the field of chemical plant automation is offering high-quality and reliable automation system controllers, analyzers and solutions with professionalism.

Falling Film Evaporator

Heart of the heat economy 
Vertical shell and tube heat exchanger, with a laterally or concentrically arranged centrifugal separator. The way an evaporator plant works has a crucial impact on the heat economy of sugar factories and refineries. Perfectly tailored to the overall process, it allows effective action to increase the energy efficiency of upstream or downstream process steps.




Sulfonation, also spelled Sulphonation, in chemistry, sulphonation process is widely applied for the production of the corresponding sulphonic acid (LABSA), Important sulfonation procedures include the reaction of aromatic hydrocarbons with sulfuric acid, sulfur trioxide, or chlorosulfuric acid.






Esterification is a chemical reaction that occurs between the acid (usually carboxylic acid) and the alcohol (or compounds containing the hydroxyl group) where esters are obtained. Ester is known as esterification.

Multiple Distillation

Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture.
In the field of industrial chemistry, large amounts of crude liquid products of chemical synthesis are distilled to separate them, either from other products, from impurities, or from unreacted starting materials.



Thermic Fluid Heating Controls

It is a heat source that can supply heat of temperature from 300 c; it heats a fluid (Thermic Fluid) to required temperatures and the fluid then be passed to process points where heating is required. Installation of Temperature indicator cum Controllers indicates the temperature and prevents undesired overheating at the inlet and outlet of the system.

Mixing & Blending Automation

Automation can be involved at every level, from mixing, blending, and load out (attended and unattended), track your inventory in real-time. This means no more speculation. Be sure with your forecasts for the year, and dramatically reduce shrink.
Our Process specialists
• Designing hygienic or aseptic process
• Developing and integrating the correct automation system (monitoring, process control, etc.)
• With automated mixing and blending the time savings is tremendous and the amount of loads that can be handled in a day increases dramatically.
We can determine your companies exact needs and engineer a solution that allows you to meet all goals. Sierra Instrumentation & Controls offers several levels of Mixing & Blending Automation Solutions to meet the client requirements.

Cryogenic Liquid Nitrogen Plant Automation

Nitrogen, as an element of great technical importance, can be produced in a cryogenic nitrogen plant with a purity of more than 99.9999%. Air inside a distillation column is separated at cryogenic temperatures (about 100K/-173°C) to produce high purity nitrogen with 1ppm of impurities. 
High purity liquid nitrogen produced by cryogenic plants is stored in a local tank and used as a strategic reserve.
Sierra Instrumentation & Controls has successfully accomplished my company’s projects on Cryogenic Liquid Nitrogen Plant Automation using PLC & SCADA Projects with centralized controls. The field of chemical processes varies from simple to complex batch processes with different formulas & multiple complex controls with the need for planned automation.
