Shell-and-tube heat exchangers for acute and recovery steam in the production of alcohol and bioethanol.

Production of valves for a distillation column made of 08Cr13 steel with a thickness of 2 mm.

Rectification columns are used to separate oil into fractions during distillation.

The internal devices of the plate and the column body are made of heat-resistant stainless steel.

Our company manufactured valves for the distillation column from 08Cr13 steel, a 2 mm thick heat-resistant stainless steel.

The use of energy resources at enterprises producing ethanol, in particular “heat” and “cold,” play an important role in determining the cost of production and the price of the finished product.

The most effective method of heat recovery is “heating” the distillation column (DC) with alcohol steam from the distillation column (RC). This method works as follows: alcohol steam from the boiler is supplied to the annulus of the recuperative boiler of the boiler; stillage from the bottom part of the DC is supplied by a circulation pump first to the pipe space of the recuperative boiler of the DC, which is also a reflux condenser of the DC, and then to the pipe part of the live steam boiler of the DC. Next, it is fed into the bottom part of the DC for further heating of the stillage to the required temperature and cooling (condensation) of alcohol vapor in the DC.

For force majeure and commissioning modes, live steam boilers are installed. Alcohol vapor condensate (reflux) is fed to the upper plate of the water chamber.The prerequisite for this method of “heating” is the operation of the columns under different pressures: the distillation column is under low pressure (vacuum), and the rectification column is under excess pressure.The use of reheating is also supported by the fact that this heating method saves thermal energy and cold and reduces the cost per unit of production.

Consider an example of regenerative “heating” for a plant with a capacity of 3000 dal/day

The total energy consumption of the two columns is 46 kg/dal of thermal energy from live steam and 42 kW/dal of cold energy from recycled water.

Working according to a recuperative scheme (using secondary heat) allows you to save thermal energy in the form of high-temperature steam for heating the distillation apparatus and part of the energy for cooling the distillation column.

The total energy consumption in two columns with a recuperative scheme is as follows:

• Thermal energy in the form of high-temperature steam 26kg/dal;
• cooling - 26 kW/dal of circulating water.

This means that in a distillation column-distillation column connection, the energy that is saved only by using preheating is as follows.

• Thermal energy of live steam 20kg/dal;
• 16kW/gave “cold” from recycled water.

This method of heat recovery between the rectification and distillation columns was implemented at Uzlovsky Alcohol Plant LLC. This made it possible to reduce heating steam consumption and, accordingly, fuel consumption by 30%.

Ricardo diesel generator models are a high power power plant equipped with a professional diesel engine.It can be used as the main or backup source of energy in everyday life, in emergency services, in construction, in hospitals, gas stations, etc.Ricardo is able to work up to 24 hours without refueling and stopping, depending on the consumption and power of the model.

Features of diesel generators:

Engine

The model has an original RICARDO diesel engine. Starting autorun, without your participation. The engine is designed specifically for diesel electric generators.

Industrial generators are equipped with a radiator for cooling, so they can work continuously as the main power sources (stopping only for refueling).Works on diesel fuel. It has a built-in oil sensor with the function of automatic shutdown of the device if the oil level is extremely low, as well as an engine temperature sensor that will ensure smooth operation and protect against engine overheating.Engine parts are made of high-quality hard alloys, which guarantees the reliability and durability of the device.

Corps

The Ricardo engine is protected by an all-weather noise-absorbing housing. Which allows you to protect the main nodes of your generator in working condition for many years, and very importantly, reduces noise (can be compared to a working passenger car).

It has an anti-corrosion coating that ensures stable operation even in conditions of high humidity.

AVR automatic reserve input

The diesel generator set is equipped with an AVR unit, which makes it possible to quickly and almost imperceptibly for the connected equipment to switch from power supply from the main network to a backup generator and, importantly, without human intervention. Switching is done automatically.

Due to the presence of the AVR system, the generator can be used to provide facilities with increased reliability of power supply, such as: medical institutions, production lines, banks, gas stations, incubators and other cases where uninterrupted current supply and uninterrupted operation of connected electrical appliances are important.

Alternator

Ricardo has a synchronous alternator.

It is capable of withstanding high-amplitude variable loads while producing a stable output voltage (fluctuation within ≤1.0%).The high quality of the winding material is 100% copper, which ensures the longevity of the generator.

Control panel

The multifunctional control panel allows you to monitor all processes, performance and parameters of the diesel generator. If the generator is equipped with an AVR, the start mode is set from the control panel, manual (start when the button is pressed), automatic (the station starts and shuts down automatically without human intervention).

Advantages of the generator

A high-power power plant with an increased fuel tank volume is capable of providing electricity to a large suburban farm, construction or commercial enterprise. Suitable for the needs of repair crews or emergency services. A versatile, reliable and durable device that can be used as the main and backup power source.

Frugality

The diesel engine has a long engine life, many times greater than that of gasoline counterparts. Despite the high power of the engine, the generator consumes fuel economically, and the fuel itself is cheaper than gasoline.

And yes, buying a Ricardo PR358GF diesel generator is a smart investment that pays for itself much faster than its analogues on other types of fuel.

Autonomy

The device is completely autonomous from stationary power sources. It does not require special operating conditions, provides a stable voltage, which allows you to use it as the main power source where the network is not available.

Ease of use

The generator does not require increased safety (except for the operating conditions described in its technical documentation), it is easy to use and reliable.The simple start system works even when working in low temperatures.

Reliability

All Ricardo generator parts are original, manufactured to Ricardo's high quality standards. Water cooling extends the life of the engine, and a strong protective casing reduces the risk of downtime due to external damage to the generator.

All weather

Tests show that the generator works equally stably both at low (up to -30 C) and at high air temperatures at any level of humidity.

Security

All current-carrying parts of the device are reliably isolated, their contact with external panels or the operator is excluded, therefore, even with the engine running, it is absolutely safe for you to touch the generator. Grounding will protect you from electric shock, and the system of sensors and fuses will ensure safe shutdown of the device in case of overheating or voltage increase above the established norms.
