For the successful transportation and refining of crude oils, a whole raft of additives are required. These vary from simple surfactants through to complex blended scale and corrosion inhibitors. The chemical additives are injected in small quantities at high pressure and are critical to the whole refining process. Consequently, careful monitoring of their addition to any process is essential.
Petrochemical additive injection fluids vary in both viscosity and density, and any flowmeter installed into a plant should be able to cope with a wide range of physical and chemical properties.Unlike other types of flowmeter, measurement accuracy of Oval Gear flow meters improves as the liquid viscosity increases, from a nominal 1% of reading to around 0.1% of reading at higher viscosities.
Titan’s Oval Gear range of flowmeters include ATEX compliant IP67/NEMA 4 protection models, designs that can be pressure tested in-house up to 1200 bar, and devices that offer intrinsically safe options to be used in potentially explosive atmospheres. These oval gear meters offer excellent chemical resistance whilst maintaining high performance and 0.1% repeatability. Titan’s proprietary oval gear design ensures these flow meters give reliable, high performance in high pressure applications.
Titan’s standard Oval Gear models used in additive injection are manufactured with options in materials compatible with the presence of strongly acidic or basic chemicals, such as 316 stainless steel, aluminium, and non-metallic PEEK, with pressure ratings from 50 bar to 950 bar (for custom-designed models). Benefiting from a compact, rugged design, Titan’s Oval Gear flowmeters are proven to operate reliably even at high pressures and at temperatures up to 150°C, providing long-term performance with minimal maintenance.
Adapting designs to meet specific high-pressure requirements and aid chemical compatibility, the use of non-magnetic materials and exotic metals, such as Hastelloy and Titanium, are examples of our growing bespoke flow meter capability. Titan has partnered with OEM customers to provide optimised flow metering solutions for oil, gas, petrochemical and green energy applications. These have included bespoke oval gear flow meters for marine fuel flow measurement, monitoring the volume of grease being supplied into a wind turbine main bearing mechanism, high pressure intrinsically safe units for offshore oil drilling additive injection, and for biodiesel plants converting bio waste into sustainable biofuels.
