Production & LACT Sampling
The CLIF MOCK LGS-2000* gas and light liquid sampler is an easy to use means of dependable sampling of liquid or gas flow streams. The CLIF MOCK LGS-2000 sampler is easily configured to sample product in proportion to time or volume using the CLIF MOCK True Cut LGS-1* pneumatic positive displacement sample pump to collect product samples from the pipeline and deposits them into a low pressure receiver or constant pressure cylinder that can be transported for offsite analysis.
The M20-3 Mixing System is designed in accordance with API 8.3, to thoroughly mix crude oil samples. The system consists of an explosion proof motor, a gear pump, and an inline static mixer mounted on a carbon steel drain table.

The CLIF MOCK True Cut sampling technologies have been a workhorse of the crude oil sampling world since its inception 60 years ago. The CLIF MOCK True Cut technologies are used for sampling conventional crude oils, condensates, and refined products that are below viscosities of 350 cSt and gauge pressures below 1,500 psi. A selection of accessories can be used with the sampling technologies to help with the operation of the probe and the insertion of the probe into smaller line sizes.
Cameron’s CLIF MOCK™ True Cut™ R Series portable sample receivers are designed to meet or exceed all API, ISO and ASTM industry standards and are available in one, two, and five gallon sizes. The receivers help ensure proper handling of crude oil and other petroleum products. Cameron’s CLIF MOCK True Cut P Series portable sample receivers are available in two quart, two gallon, and five gallon sizes. The receivers help ensure proper handling of petroleum products.
Blending
Jiskoot is also an internationally acknowledged leader in
the field of in-line blending systems. With over 40 years
experience of blender design Jiskoot can supply solutions
ranging from simple ratio control two-stream blenders for
fuel and crude oil applications through to large systems
with automatic density or viscosity blend optimisation.
Jiskoot is able to provide complete blending solutions from
design to start-up and our systems are guaranteed to
operate as a totally integrated part of the process plant
and reduce operating costs.
Jiskoot can design a range of turnkey, integrated inline
blending systems for process liquids including crude oil,
LPG, LNG, ethanol and bunker fuel oil.
JISKOOT Blending Products
When designing and executing an In-Line blending project, selecting the correct analyzers is critical to the accuracy of its performance. These analyzers are the one critical component that allows the rest of the blending system (system control, flow control and mixing) to continually adjust the blend, to meet the required physical property specifications, but also optimize your companies operational efficiency and profitability.
The InSpec blender controller is a true 3-term PID controller, suitable for controlled rate batch blending, wildstream responsive blending and analyzer trim blending applications. The InSpec Enhanced Blend Controller can be developed in two different form factors for Safe-area and Hazardous area applications. It is designed to control every type of in-line blending system, from simple two-stream systems to complex multi-stream blenders. It can operate in controlled rate or flow responsive modes providing either the regulation of both streams to achieve the required flow, quantity, quality and ratio, or for a wildstream application, where you are not able to control the main flow stream, to maintain a second stream, or additive stream to the required ratio with respect to the wild unregulated stream.
Mixing at the outlet to a blender header is crucial to ensure that the product delivered is fully homogenous. Mixing becomes even more important if analyzers are mounted in the blender header to provide quality optimization of the blended products. Our mixing systems are all designed in accordance with international sampling standards to guarantee product homogeneity.
Blending System types
Density or API gravity trim blenders are suitable for blending liquid hydrocarbons where the quality of the feedstock is not stable or varies due to inconsistent supply or product layering in tanks and the main parameter of importance in the final blended product is density.
Ratio control blenders are suitable for any liquid hydrocarbon blending application where the quality of the feedstock is consistent and known. The final blended product is produced to an extremely accurate component ratio determined by the flow meters, the efficiency and linearization of the control system. Accuracy of better than +/- 0.25% over the full metering range can easily be achieved.
Viscosity trim blenders are suitable for blending liquid hydrocarbons where the quality of the feedstock varies due to inconsistent supply or tank layering and the main parameter of importance in the blended product is viscosity.
blending Systems
Today bunker terminals and tank-farms are implementing in-line blending as a key component of their operations. A modern, ratio control or quality trim in-line blending system can improve flexibility, reduce capital lock-up in blended product and reduce the time required to produce blends.
The main objective of blending LNG is to blend low value “Lean” LNG with high value “Rich” LNG to maximize the sale price and improve the quality of the lower specification product. This is achieved by ensuring that the final product is blended to a target BTU specification, at the lowest possible cost.
Annual payback is in the region of $7M – $17M based on a plant producing 3M tons a year.
It is desirable to optimize the energy value of the LNG, ensuring specifications to the various regional areas that exist around the world. Sensia JISKOOT’s LNG blender ensures that the blended LNG is within specification under all circumstances, whilst minimizing the commercial cost.
LPG (Liqid Petroleum Gas) is becoming widely used for heating and cooking rather than biomass.
The demand for blended LPG (propane and butane blends) has increased significantly due to the growth in CFC free propellant and liquid gas based fuel production.
The propane and butane feedstocks used for blending LPG often vary in quality and for this reason in-line LPG blenders are often supplied with a density trim control system.
Crude oil blending is often undertaken to increase the sale price or process-ability of a lower grade crude oil by blending it with a higher grade, higher price crude. The objective is to produce blended crude oil to a target specification at the lowest cost using the minimum higher cost crude oil.
Ethanol is used in a wide range of industries and before dispatch from a bonded plant is often blended by adding a variety of denaturants to the ethanol.
An in-line ethanol blender allows the product to be denaturized as it is loaded into road tankers reducing the blending and despatch process to a single operation, minimizing wastage and avoiding the need for intermediate storage. The ethanol blending process is fully automated once the recipe and required volume are selected. Denaturants are automatically selected from multiple sources depending on the recipe. Ethanol blenders incorporate an ethanol flushing cycle after each batch to avoid contamination of subsequent batches.
