Gate price plant

If one considers that the operator at the remote site may have additional costs, such as increased shipping and possibty import duties, this "gate price" is effectively reduced. Assuming that these additional cost factors amount to 25/t, then the te price for this methanol in the preceding example is 175 25 = 150/t. At 120 and 140% plant cost and 150/t methanol price, with an IRR of 15%, the corresponding natural gas cost is about 1.55 and 1.05/MMBtu, respectively. 

The cost of treatment to process one tonne is difficult to define since it depends on many factors such as scale, location, scope, preparation stages, and economic parameters used. As a rough example, for a 25,000 tpa plant in Western Europe (1998 prices), BP estimated the investment to be 15 to 20 million. This would imply a gate fee of around 172 per tonne (some 250). For a 50,000 tpa plant the gate fee could be 100 per tonne (some 150).These figures are net, i.e., include product values but exclude collection and preparation. 

The intervening years to 1981 have seen several world market sulfur demand cycles which have effected the rate of acceptance of these new sulfur sources but slowly the recovered sulfur product has taken its place alongside other world sulfur sources such as Frasch mined and pyrites. In very recent times there have even been moves to re-open very sour gas wells as sulfur wells as world demand for this key commodity has grown and prices have crossed 100/tonne FOB the plant gate.

The electricity prices estimated by H2Sim are at the plant gate. If hydrogen production is not done on-site, one must include transmission and distribution costs, t3q)icaUy in the 2 cent/kWh range. H2Sim allows the user to evaluate the impact of these prices on hydrogen, as well as consider the impact of off-peak electricity. Table 6.3 summarizes the default assumptions about electricity costs in 2020. 

The production sensitivity and capital cost sensitivity for electrolysis allow the user to alter the source of the electricity. The default electricity option assumes electricity is produced using gas combined cycle technology (GasCC). The user may also directly set a price (User Set option). The electricity costs are calculated at the plant gate and do not include transmission and distribution (T D) costs. T D costs may be added by the user (Electricity Transmission and Distribution box). 

Basic technological and technical data collected during the UNIDO workshop on Minifertilizer Plant Establishment, held in Lahore in 1983, show an alternative means of developing the fertilizer industry and allow the preliminary technical assessment of such a concept. However, it is not possiNi to recommend an economical size fertilizer plant if only unit production costs are known. The cost of the marketing and delivery system is a second component of the fertilizer price at the farm gate, and this price should be considered when determining the size of the fertilizer industry operation. 

Existing transportation infrastructure, such as road n works, navigable rivers, and railways, presents a great advantage for locating a fertilizer plant. Today even medium-scale plants should expect to transport more than 1 million tonnes of material per year. Therefore, access to a transportation network is very important for investment costs and future farm-gate fertilizer prices. Constmetion of a 1-km (6-m width) road may cost from US 1-3 million, and no investor would be able to recover these costs from the profits of fertilizer production. Construction of railway or port facilities should...
