Small-Scale Gas-To-Liquids Gains Momentum

CompactGTL gets order for Kazakstan plant


Published:

To date, there are only three commercial gas-to-liquids (GTL) plants in the world — in Malaysia, South Africa and Qatar. A fourth is expected to come into operation in Angola this year. Adoption of GTL was limited as gas had been considered a costly feedstock relative to crude oil. However, with the present crude oil prices, the industry is starting to reconsider the commercial viability of GTL projects in North America and Central Asia.

Shale gas in North America and restrictions on gas flaring in Central Asia are now driving the market to look more closely toward smaller size GTL plants which, if not enjoying the economy of scale, are more flexible and easy to realize. Unlike larger GTL projects, which seek to profit from sales of the final oil products produced through low gas feedstock costs, the goal of smaller GTL projects is simply to tackle the problem of gas flaring. Hence, the opportunity cost of choosing GTL production over other modes of gas utilization — which will require far larger quantities of gas to be viable — is much lower for small GTL projects. Moreover, the modular nature of small GTL plants could also speed up construction for faster monetization. Therefore, despite comparable costs, smaller projects could be deemed more economical than the penalties firms could face from gas flaring.

Caterpillar Releases Valves, Seats For Pressure Pumping Customers

Caterpillar has released its Cat valves and seats for well stimulation pump fluid ends. Cat 4- and 5-series valves and seats are designed to maximize interchangeability across the Cat well stimulation fluid end line and be dimensionally compatible with industry standard fluid ends in the 2000 to 3000 hp (1491 to 2237 kW) range. Fluid end valves and seats are highly-consumed parts in well stimulation operations and, as a result, are frequently replaced. Historically, Caterpillar uses valves and seats obtained from alternate sources. Caterpillar’s new fluid end valves and seats provide decreased wear and extended life to pressure pumping customers, the company said. The material life of the fluid ends is extended by optimizing the geometry of the Cat valve and seat, increasing the contact area and improving the distribution of forces, resulting in reduced material fatigue, Cat said. The flow area is increased by balancing the pressure drop across the Cat valves, reducing flow restrictions and the potential for cavitation. Additionally, impact forces are reduced as the contact area between valve and seat has nearly doubled from previous designs. Caterpillar manufacturers a line of pressure pumps with maximum inputs ranging from 600 to 3000 bhp (447 to 2237 kW). The new valves and seats can be ordered from the global Cat dealer network.
