Oil systems

Design parameters

For over 30 years, OELTECHNIK oil supply units have been supplied as so-called compact units. The delivery program ranges from modular standard units to special lubricant, sealant and standard oil units and water injection units. These are used mainly in process compressors in industrial use.

OELTECHNIK supplies complete engineering in accordance with the customer’s requirements. This means that the units are fitted out with both appropriate process technology and measurement and control technology.
If required, international regulations of the petrochemical industry or the standards of the American Petrol Institute (API) can be taken into account during construction. Basically, all units are designed to operate in continuous service and guarantee an enormously long service life.

OELTECHNIK has designed, engineered, tested and continuously improved its oil system product in response to the needs of the turbo machinery equipment manufacture. In-house testing facilities allow customers to witness oil system tests according to API 614 and other customers' specified requirements. OELTECHNIK's oil consoles are special engineered systems designed to perform an exceptional job in:

  • Controlled oil cooling
  • Filtering of all abrasives from bearings and other sources
  • Degassing the oil coming into the system

OELTECHNIK has supplied lube, seal and control oil system to the international market for over 35 years. Oil systems designed and manufactured in accordance to API Standard 614 are a daily routine.
OELTECHNIK's oil systems are in use worldwide. Our design and manufacturing capabilities cover all international design codes and national regulations. As oil coolers, filters, accumulators, and occasionally also oil reservoirs are considered pressure vessels, they have to be built according to codes and regulations of the country of installation. With us you can establish a world wide standard of your product since we have the knowledge, capability and certified authority to build pressure vessels to all international design codes and national regulations.

Element coolers

Design parameters

OELTECHNIK has developed, tested and continuously improved the EKE Element Intercooler product program in response to the need of the compressor industry. Over decades the in-house developed software has been checked against test performance of our equipment.
OELTECHNIK has always taken challenges to extend the applications of the EKE Element Intercooler to serve our innovative customers' requirements. OELTECHNIK's products are successfully in use worldwide. Our design and fabrication capabilities are all international design codes and national regulations.

The EKE Element Intercooler with enhanced surface finds its application where heat has to be transferred from a poor heat conducting fluid (e.g. gas) to a liquid fluid or vice versa. The liquid fluid is placed on the tube side, and the gaseous fluid is on the shell.
The EKE type heat exchanger allows with its enhanced outside tube surface to compensate the poor thermal conductivity of the gas. The gas flow is directed in one pass perpendicular through the enhanced tube bundle.
Even numbers of passes on the tube side are forming a combination cross-flow and counter-flow which allow for temperature approach of 5K.

 

Capabilities – Range of application:

 
Design pressure: 2-90 barg 29-1305 psig
Design temperature: -25 - 200 °C -13 - 392 °F
Minimum flow rate: ~7000 Nm3/h ~4120 scfm
Maximum flow rate: Function of operating pressure and allowable pressure drop
Minimum shell diameter: 560 mm 22 inch
Maximum shell diameter: ~3500 mm ~138 inch

 

Typical fluids :

Shell side: Wet air, dry air, Nitrogen, Oxygen, NH3, CO2, CO, CH4 and others
Tube side: Water, Glycol and water glycol solutions

 

Material combinations:

Tubes: 90/10 CuNi, 70/30 CuNi, Admiralty, 304 SS, 316 SS, Duplex, Titanium and all other commercial available materials
Fin: Aluminium, CU, Stainless steel, Steel
Tube sheets: Carbon steel, 90/10 CuNi solid, cladded, Stainless steel and all other commercial available plate materials
Shell side: Carbon steel, Stainless steel

 

Beneficial features:

  • Lowest pressure drops on gas side due to optimum flow guiding through the shell and the tube bundle of the intercooler. Energy consumption is minimized.
  • High flexibility in nozzle arrangement, in- and outlet connections for the gas can be located in a wide range on the shell without limiting the heat transfer performance.
  • Internal moisture separation device: For wet gas application the dew point might be reached which creates water knock out. The EKE Intercoolers allow for moisture separation devices inside of the shell.
  • Easy bundle removal: with or without the bundle removal device, the EKE Intercooler Bundle can be removed and inserted readily. Two stainless steel angle iron guide the brass roller pairs installed along the two lower edges of the bundle.
  • Stainless steel Y-seals with highest performance: A multiple layer stainless steel Y-shaped seal separates the hot and cold gas side. The seal type lasts several maintenance cycles.
  • Numerous options of enhanced surface: Due to the options of plate fin, helical high fin and bi-metallic high fin as means to provide enhanced surface, numerous combinations of fin and tube material are feasible.
  • No chance of vibration: The plate fin design connects all bare tubes with the fin to each other. The unsupported length is going towards zero. For the high fin tubing several spacer options are available. At the spacers' locations, rigid clamping bars are installed with adjustment features to optimise the tightening process.
  • Bundle removal device: A tool to remove and insert the bundle during maintenance can be designed upon customers' request. Adjustment options on this equipment allow to use one bundle removal device for a whole set of EKE Intercooler.

Shell & tube heat exchangers

Design parameters

OELTECHNIK has developed, tested and continuously improved its shell & tube product program in response to the challenges of the industry. The in-house developed software is based on recognized literature such as VDI Wärmeatlas and HEI. It has been checked against actual test performance of our equipment. OELTECNIK has always taken challenges to explore further design options for shell & tube heat exchangers. Shell & tube heat exchangers are rated, designed and fabricated in-house and can be supplied according to individual customer’s specifications.

OELTECHNIK's products are successfully in use worldwide. Our design and fabrication capabilities are covering all international design codes and national regulations.

Our type OK coolers are standardized from 100 mm (4”) to 400 mm (16”) in shell diameter. Typically, oil is on the shell side and water on the tube side. For every application the coolers are individually check-rated with our thermal rating programs. For higher flow rates custom tailored designs are prevailing. Certainly, the OK type shell & tube heat exchanger can be used for other liquid to liquid applications.

The type LK indicates that one fluid is gaseous or has major gas components. Together with our customer we decide whether the gaseous fluid is on shell or tube side. Factors like design pressure, desired nozzle location, aggressiveness of fluids, desired material combination, thermal performance and allowable pressure drop influence the decision about fluid location.

OELTECHNIK will assist you in making the most economical selection under consideration and evaluation of all parameters.
