News from Krohne UK: Krohne has been selected as a Frame Agreement supplier for flow and level instrumentation on one of the world's biggest oil and gas developments, the Karachaganak project in Kazakhstan. The Karachaganak project is a joint venture between four leading international companies; BG, Eni, Chevron Texaco and LUKOIL, to develop the giant gas condensate and oilfield in Western Kazakhstan, which will produce more than 7 million tonnes of liquids per year.
Krohne has already successfully completed two contracts for Bechtel and Snamprogetti as part of the Karachaganak project, supplying over US$1,2 million worth of flow and level equipment. The first contract involved supplying equipment for the new facilities and the order included Krohne's H250 variable area flowmeters, Ultrasonic 500 flowmeters (UFMs) and BM70 radar level gauges, as well as a range of more basic instrumentation such as PD flowmeters, Pitot flow tubes and level probes. Krohne equipment is also playing a key role in the Export Pipeline project from Karachaganak to the CPC Pipeline at Atyrau, with the supply of four UFM 500s with 24" Hastelloy 1500 RTJ flanges. Two of these units are being used for flow monitoring, and the other two are employed in leakage detection.
Krohne is an acknowledged leader in the supply of ultrasonic flowmeters to the hydrocarbons industry. Unlike turbine meters and PD meters the UFM is non-intrusive flow measurement technology that causes no obstruction to the flow, thereby offering 'zero pressure drop' which means less powerful pumps can be used producing savings on energy costs and resulting in higher flow rates. The Krohne UFM range delivers outstanding accuracy - and because there are no moving parts to wear, the instruments are virtually maintenance free.
The comprehensive range of flow and level instrumentation available to Karachaganak contractors from Krohne also includes the BM70 radar level meter and Krohne's H250 variable area meters. The BM70 is approved by the PTB for use in intrinsically safe circuits (EEx ia IIC and EEx ib IIC) in accordance with ATEX (Approval No: 1. Supplement to EC type approval PTB 99 ATEX 2061 X). It is suitable for measuring the level of fluids with low dielectric constant such as organic solvents, benzene, toluene and hydrocarbons, and can also accurately measure low tank levels, due to its unique 'tank bottom' following function. The H250 variable area meter is well suited for process gas or fluid at temperatures up to 300°C, pressures from 1,6 to 4 MPa, and flow rates from 2,5 to 100 000 l/h, (water) and 0,7 to 600 m3/h air). Special versions to suit customer requirements, such as the high temperature H250s, which measure flow at process temperatures up to 400°C, and high pressure H250s for up to 50 Mpa (dependent on flow tube size and temperature) are also available.
