JSC «EC «Technohim» designs and manufactures the following process units:
- filtration & separation,
- external cooling,
- measurement of an expense,
Units for use as a hardware component in installations for the oil, gas and chemical industries and enterprises; represent maximum prefabrication product as a block or building unit.
Separation and filtration unit
The main purpose:
- capture impurities (0.1 to 50 microns or more) contained in the stream environment;
- separation of the stream consisting of gas and liquid phases, respectively a gaseous and a liquid phase.
The main equipment: filter and separator.
The value depends on the fineness of filtration requirements that apply directly to the customer, or the need to ensure the safety and efficiency of the equipment located behind the filters.
The composition of the unit and the type of filter used depends on the composition, physico-chemical parameters of the medium, the presence of mechanical impurities, their number, size and composition.
Depending on the type of filter the choice of the filter element.
The filter elements can be regenerable, not regenerable and provides all the required service life without replacement.
Response of the filter - is specified filtration fineness, the material of the filter element, the performance in the medium, pressure, temperature, allowable pressure drop (for the destruction and replacement) and climatic performance.
Depending on the presence and number of phases are different types of separators.
The main types of separators:
- two-phase, three-phase;
- horizontal, vertical.
In the selection of separation equipment is taken into account the performance of flow, pressures, temperatures and fractional composition of stream.
The principle of operation is based on capturing the liquid phase of the fluid flow and accumulation in the bottom part of the separator to further fluid diverting to achieve a predetermined level through drain fitting.
Depending on the flow capacity of the liquid phase and the amount of applied liquid withdrawal or automated, or manual.
The main purpose: reducing the pressure of the fluid or gas to the required process parameters.
The main equipment: pressure regulators.
Depending on the equipment used by different pressure regulators control method and can maintain pressure.
The operating principle of pressure regulators are divided:
- regulators of direct action and indirect controls;
- discontinuous and continuous.
The controller direct regulatory authority is under the control parameter either directly or through a dependent parameter.
The controller indirect sensing element acts on the regulator outsiders independent source of energy that can be air, gas, liquid, and so on.
Both types of regulators consist of a valve sensitive (measurement) and control elements.
Number of pressure regulators is determined by the operating conditions of the equipment for maintaining the desired pressure, as well as according to customer requirements.
External cooling unit
The main purpose: cooling fluid flow by using external energy source.
The main equipment: air coolers and refrigeration units, using as a cold stream different refrigerants.
The main principle of air coolers: use of ambient air as a coolant for cooling the hot fluid flow through the tube bundle to the desired temperature parameters (10-30°С).
The use of this type of external cooling is limited to the ambient temperature in the summer and are not always able to provide the required flow temperature. In some cases, a coolant circuit with the addition of the intermediate heat exchanger and pump.
For a deeper cooling applied install artificial cold.
The basic principle of the install artificial cold - used for artificial cooling in processes requiring low temperatures.
This unit is characterized by its own refrigerant circuit with its own engineering networks and automatic control system.
Components and scope of the equipment specified for each request and are specific to each calculation.
The main purpose: displacement and compression of gas for process.
The main equipment: compressor machines.
Depending on the degree of compression of the following types:
- fans - to move large quantities of gases;
- gas blower — for moving gases at relatively high resistance to the gas pipeline network;
- compressors - to create a high pressure;
- vacuum pumps.
According to the principle of action:
- Piston. Compression occurs as a result of reducing the volume containing the gas, the reciprocating motion of the piston;
- Centrifugal. Compression occurs under the action of inertial forces generated by the rotation of the impeller;
- Rotary. Compression occurs at a volume reduction. Containing the gas, when the rotation of the rotor eccentrically located;
- Axial. Compression occurs when the gas motion along the axis of the impeller and guide vanes.
In this unit the equipment represents difficult system, with existence of own control system and engineering systems.
The main purpose: heating the fluid flow necessary to the parameters set in the process.
The main equipment: heat exchangers.
Depending on the mode of heat transfer applies two groups of heat exchangers:
- surface heat exchangers — heat transfer between the environment occurs through the separation of the heat exchange surface - blank wall.
- mixing heat exchangers — heat transfer occurs between the environment with their direct contact.
The main types of surface heat exchangers:
Substances involved in the process of heat transfer are called coolants. Heat transfer fluid having a higher temperature is called the heating agent.
Depending on the technology used heating medium can be steam, hot water, electricity, gas (intermediate heat transfer fluid) and high-temperature heat transfer fluids.
The choice of the heat carrier depends on the demanded temperature of heating and need of its regulation, and also in compliance with requirements in inquiry.
In technically justified cases, possible to use a specially designed heat exchangers.
Measurement of an expense unit
The main purpose: measuring the amount of flow.
The main equipment: flow meters (separate counters or measuring systems).
Depending on the desired type of flow accounting distinguish:
- commercial metering;
- operational (technical) metering.
Number of working measuring lines metering defined by the project.
For each group of measuring lines connected to one collector, provides a back-up measuring line.
For operational accounting provides a measuring line and bypass with a shut-off device.
The main purpose: mixing multiple streams into a single stream with certain process parameters.
The main equipment: mixers.
The design of the mixer every time is selected on the basis of calculation, depending on the performance parameters and process stream flows to be mixed.
